The SUGAR Expert: This is What Too Much Sugar Does to Your Baby (Eat Carbs This Way Instead)

Pregnancy only lasts nine months, but what you eat during that time can shape your child for life. Jay Shetty welcomes back biochemist, bestselling author, and “Glucose Goddess” Jessie Inchauspé for a conversation that goes even deeper into the impact she’s had on millions of lives. This time, they focus on something few people truly understand: pregnancy isn’t just a waiting period, it’s a critical window that can shape a child’s physical, mental, and metabolic health for life. Jay and Jessie unpack why so many parents feel under-informed, how outdated myths like “eat for two” still dominate the conversation, and what the science actually reveals about the nine months that truly count forever. Jessie breaks down complex biology into simple, actionable insights. She explains how key factors: blood sugar balance, protein, choline, and omega-3s play a critical role in brain development, metabolism, and long-term disease risk for your child. Jay guides the conversation with curiosity and care, highlighting how small, intentional shifts during pregnancy can create lifelong resilience, while also acknowledging the systemic failures that leave parents without clear guidance or support. In this interview, you'll learn: How to Support Your Baby’s Brain With Just Four Key Nutrients How to Reduce Blood Sugar Spikes That Affect Your Baby How to Build Your Baby’s Brain Before They’re Born How to Lower Your Child’s Lifetime Risk of Diabetes How to Use Protein to Stabilize Energy and Nausea How to Care for Your Mental Health After Miscarriage How to Make Small Food Choices That Create Lifelong Impact Life doesn’t come with a manual, we’re all doing the best we can with the information we have. When we learn more, we can make better choices, not just for ourselves, but for the people whose futures depend on ours.

    Debunking the Biggest Pregnancy Myths

    1. JS

      The biggest thing I think that I want to start with is so many people feel that you can eat whatever you want when you're pregnant. There's really no rules. Why do you disagree with that?

    2. JI

      There are many myths around pregnancy. That's one of them. There's the myth that you should eat for two, the myth that you're gonna gain weight anyway, so it's the perfect time to eat all the stuff you never usually eat and that you don't think you should eat because they're not good for you. There's another myth around, uh, your baby will get what he needs from you. And I think the main myth, Jay, is that when you're pregnant, you have a bun in the oven. Have you heard that expression before?

    3. JS

      I have heard that expression, yes.

    4. JI

      Okay. So I was told when I was pregnant by people in the street, "Oh, you have a bun in the oven." And I think this is where most of our problems starts because as I was thinking about this metaphor, I thought, "There are so many things wrong with this sentence." First, it implies that as the mom, you are an oven, meaning-

    5. JS

      [laughs]

    6. JI

      No, but seriously, that you are this passive box of heat and time. It implies that when you're pregnant, all you gotta do is keep the temperature at the right temperature and just wait. And then it also implies something a bit more subtle. 'Cause if you bake something, like if you're making, I don't know, a brownie, the moment you put the brownie in the oven, it's gonna stay a brownie. The oven doesn't change the recipe, right? So it implies that your baby, the moment that the sperm meets the egg, it implies that at that point, the baby is set in stone, and that all you gotta do is wait and let nature do its thing, and the baby's gonna come out. I learned in the science that actually, what happens during the nine months, and specifically what you eat during the nine months, co-creates the baby. So if you eat two different diets, a different baby will come out. Your diet during pregnancy is calibrating things in your child. It's setting his metabolism, the number of brain cells he has. It's setting his resilience or his sensitivity to disease. It's like you're a co-creator when you're pregnant. You're not an oven. A better metaphor is being soil out of which your baby's little seed growing. Like, you have a beautiful garden, right? If I were to give you a seed for an apple tree and I said, "Jay, you have two options. You can plant this seed in your driveway, where it's just rocks and gravel, or you can plant it in the soil in the sun," you know intuitively you should plant it in the soil in the sun. Because even if that seed has the same genetic plan, where you plant it is gonna determine how it adapts and what it becomes.

    7. JS

      Mm.

    8. JI

      And as the mom, you're the soil.

    9. JS

      Mm-hmm.

    10. JI

      And it's a lot of responsibility, for sure, and I felt that too. But the science I discovered helped me navigate that responsibility more easily, and that's what I want to share with people

  3. 3:135:49

    The Four Nutrients That Shape Your Baby’s Future

    1. JI

      today.

    2. JS

      Is it simple enough for someone who's not educated on this, i.e., myself, is it simple enough to be able to say, "This food links to this, and this food links to this?" Like, is it that obvious?

    3. JI

      It is that simple.

    4. JS

      Really?

    5. JI

      Yeah, it is that simple.

    6. JS

      Wow.

    7. JI

      So in the studies, I discovered these four main nutrients that have a outsized effect on your baby's long-term health during pregnancy. The first one is glucose.

    8. JS

      [laughs]

    9. JI

      Glucose, we meet again. So the amount of glucose circulating in your bloodstream during pregnancy is gonna program your baby's DNA to be more or less vulnerable to type 2 diabetes later in life. Second one is choline. Choline is found in eggs, and it builds your baby's brain. And we know that if there's not enough choline in a brain during pregnancy, well, the brain will be formed with fewer neurons. Neurons are the brain cells that process information. Third one is protein. During pregnancy, you need to eat more protein than usual, and animal studies show us that if you have too little protein, the baby comes out smaller and with a setting to keep his muscle mass low for life.

    10. JS

      Wow.

    11. JI

      Yes. And the fourth one is omega-3s. Omega-3s are a type of fat that come from algae in the ocean, and this fat also builds a baby's brain. And we see, for example, studies that show that if you have enough omega-3s during pregnancy, you can measure a higher IQ in a baby at four years old.

    12. JS

      No.

    13. JI

      Yes. So as I was discovering this, I was making that same face. I was like, "What? Why is there such a gap between what science knows and what parents are told?" And that's the gap that I'm hoping to bridge, 'cause this stuff is essential.

    14. JS

      So Einstein's mom basically had an amazing diet.

    15. JI

      [laughs]

    16. JS

      Like-

    17. JI

      Well, who knows? Maybe she didn't know this stuff. I think back in the day, they ate a f- a little more organ meats and, you know, foods with higher nutrition, so maybe she did have a better diet. Because the problem is today, most of us are eating a diet of processed foods. It's not our fault.

    18. JS

      Mm.

    19. JI

      The food industry, marketing messages, and so 90% of mothers today are eating a diet that is not giving them the right nutrients for their baby to grow. So 90% of moms today are missing one of these crucial nutrients. For choline, it's 90% of moms are not getting enough. For protein, it's 70%. For omega-3s, it's 75%. And for glucose, well, most moms today eat three times the recommended amount of sugar during pregnancy. And it's not their fault, Jay. This is really important. The food industry, our food landscape, has created this toxic environment, and we're all trying to eat as well as we can, but the system has failed us.

    20. JS

      What's

  4. 5:4910:23

    How Gestational Diabetes Impacts a Child for Life

    1. JS

      the negative impact of, for example, the three times the glucose, not enough of the omega-3s, not enough protein? Like, what-- how bad can it get?

    2. JI

      Mm.

    3. JS

      And what are the ex- sad experiences that mothers are having during and post-pregnancy that they may not even be connecting to those things?

    4. JI

      So for choline, for example, we know that when moms have very low levels of choline, it can lead to more brain defects that can end in miscarriage.Doctors will often tell you about folate. This is the only thing my doctor told me. He said, "Take a fo- a folate supplement." Everybody talks about this, and it's because low folate levels are also linked to higher risk of miscarriage. Nobody talks about choline, but it's just as important. So that's a main one. In terms of choline, like, if you don't have enough choline, your baby will be fine, right? Maybe his brain will be formed a little bit less optimally, but will be fine. My mom didn't eat any eggs when she was pregnant with me. When it comes to glucose, if you have a very high sugar diet during pregnancy and if your blood glucose levels are very high, we know that it means that your baby will be more likely to develop type 2 diabetes. For example, there's this condition called gestational diabetes, which means the diabetes of pregnancy, which means just having very high blood sugar during pregnancy, and when we look at the kids of moms who have gestational diabetes, 21% of the kids will have developed diabetes by age 22.

    5. JS

      Wow.

    6. JI

      Versus 4% of kids of moms who did not have gestational diabetes.

    7. JS

      Wow.

    8. JI

      And this is a big deal, Jay, because if you develop diabetes as a teenager, you have 15 years of life just knocked off.

    9. JS

      Mm-hmm.

    10. JI

      You're on average gonna live 15 fewer years than your peers. And there's all these incredible studies done on millions of women, statistics like this that are mind-blowing. Even siblings, Jay. If one was developing in the womb of the mother when she had gestational diabetes, and if he has a sibling that was developing in the womb when the mom did not have diabetes, the sibling developing during the diabetes has a four time increased risk in developing himself diabetes in his lifetime. So what's going on? Like, why is this going on? So one of the main things we need to understand about pregnancy is that while your d- baby's DNA is set in stone when the sperm meets the egg, there's something else that is not set in stone, and that's called epigenetics. It's a complicated word, but it simply means that there are these tiny little microscopic switches, like the dimmer switch on a light, that control our genes and that say, "This gene more activated. This gene more silenced." Epigenetics, switches on your baby's DNA, and these epigenetics, where do they come from? They come from the environment that you provide during pregnancy. So as a pregnant mom, you are programming your child's DNA with what you eat, and in particular, when it comes to diabetes, we see that moms with h- very high glucose levels have babies who have the genes linked to, to diabetes that are activated at birth, and this setting can stay with them for life. So it's like the moment they're born, they're born with this innate vulnerability to that condition. So that's choline and glucose. For protein, now this is fascinating, and I know you're a vegan, so I think protein is a big one for you.

    11. JS

      Mm-hmm.

    12. JI

      Okay. So animal studies show us that if a mom doesn't have enough protein during pregnancy, even if she has enough calories, so it's not about she doesn't have enough food, it's specifically she doesn't have enough protein. This is in animal studies. They see that the babies are born with epigenetic switches that say, "Keep your muscle mass small." It's as if low protein during pregnancy is sending a message to my baby saying to him, "Hey, baby, you're gonna be born into a world with not a lot of protein, so you should keep your muscle mass small."

    13. JS

      Wow.

    14. JI

      So he's getting a message. Your baby's getting information about the world he's gonna be born into with what you're eating during pregnancy. He can't see anything. He can kinda hear through the water, but, you know-

    15. JS

      [laughs]

    16. JI

      ... it's muffled, and he's like, "What kind of world am I being born into?" Because as he's creating his organs, his brain from scratch, he needs information, and your diet is providing information. So if you have a very low protein diet, your baby's gonna think, "Okay, I gotta create my body and set up myself in a way that I'm gonna survive optimally in a low protein world." This moment of pregnancy is preparing him for the rest of his life.

  5. 10:2312:46

    How Much Protein Do You Really Need During Pregnancy?

    1. JS

      Is there a recommended protein amount for pregnant moms?

    2. JI

      Yes. So for a long time it was too low, and recent studies that are using a very fancy new technique have found that it's 50% higher than we thought.

    3. JS

      That's a lot.

    4. JI

      That's a lot.

    5. JS

      Yeah.

    6. JI

      Because when you think about it, protein is not just muscle. So many things in your body are protein, like your immune system, like the molecules that make up your skin, like all of your hormones. I mean, most of your hormones. So basically, we kn- we now know that during pregnancy you need about 1.5 or 1.6 grams of protein per day per kilo of body weight, so that's about 100 grams of protein, give or take. Today, 75% of moms are not getting that amount.

    7. JS

      Mm.

    8. JI

      So most of us are sending a signal to our baby, without even knowing we're doing that, of there's not a lot of protein in the world you're about to be born into. And I, when I was reading the science, I was like, huh. I have these two friends, Gabriel and Nicholas, okay? They have kind of the same diet, and they do pretty much the same exercise. One builds muscle mass super easily, and the other one struggles so much to put on muscle. And I was wondering, well, maybe one of the reasons is their programming from the womb when they-

    9. JS

      Mm

    10. JI

      ... were in their mother's belly.

    11. JS

      Yeah.

    12. JI

      So we're not equal. Like, who we are today, you and me, we're gonna be more or less vulnerable to things depending on what happened when our mom was pregnant with us.

    13. JS

      Yeah. I mean, and, and you can feel that as well. Like, you can... As you were saying certain things, I'm like, I need to go ask my mom what she was eating when-

    14. JI

      That's what I did.

    15. JS

      Did you do that? [laughs]

    16. JI

      I called her. I was like, "Mom, okay."

    17. JS

      [laughs]

    18. JI

      "So I have this little list here. How much choline did you have? What, how many eggs?" She was like, "No, it was the '90s, honey. Like, in the '90s we only ate sugar and low fat foods."

    19. JS

      [laughs]

    20. JI

      I thought, "Man, that's why. That makes sense."

    21. JS

      That's why you're so smart.

    22. JI

      [laughs]

    23. JS

      I'm like, yeah.

    24. JI

      No, but actually, you know, I'm fine.But if I'm honest-

    25. JS

      [laughs] I'm fine

    26. JI

      ... I'm, I'm okay. But if I'm honest, Jay, like I struggled with mental health my whole life. When I was 25 years old, I was on the cusp of prediabetes. Like clearly I had a vulnerability to prediabetes. Maybe it was because my mom only ate sugar and Special K when she was pregnant.

    27. JS

      Mm.

    28. JI

      We don't know.

    29. JS

      Yeah, yeah.

    30. JI

      We're never gonna know. But the, all the animal studies, the decades of studies on animals that we have point to the fact that what happens during pregnancy sets up a baby for life.

  6. 12:4617:32

    What an Ideal Pregnancy Diet Actually Looks Like

    1. JS

      If you were talking to a room full of pregnant moms right now who are just starting their journey, their, their nine months, they're all gonna take a copy of your book away home because it's gonna help them through the next nine months, what's the first thing you'd want them to know today-

    2. JI

      [laughs]

    3. JS

      ... that's gonna shift the next nine months?

    4. JI

      I would say the first three months, don't worry about anything I'm saying because nausea is usually so bad that you can't eat anything of remote nutritional value.

    5. JS

      Is there any way of avoiding that nausea-

    6. JI

      Nope

    7. JS

      ... that moms... There's nothing?

    8. JI

      Well, if it's really bad, there's medication you can take. But for most of us, you just have to wait it out. There's some few, a little few things you can do. You can make sure your blood sugar levels are balanced, so use all of my hacks from my previous work.

    9. JS

      Mm-hmm.

    10. JI

      Protein in the morning, protein basically all the time. It's the only thing that can help really balance the nausea. I would even keep some almonds by the side of my bed and have them before I got up.

    11. JS

      Mm-hmm.

    12. JI

      Like I would literally open my eyes, not move, put my hand to the side, grab 10 almonds, put them in my mouth, and then get up. Like, that's how bad it was.

    13. JS

      Wow.

    14. JI

      Um, you could do that. Ginger helps. Exercise also helps actually. But mostly it just sucks, man. It just sucks.

    15. JS

      Did you try anything that was crazy or like a myth and then busted it and realized this doesn't work for sure?

    16. JI

      I was like, "I'm the glucose freaking goddess, and I know all this stuff, and all I can- I've been able to eat for the past month is croissant and pain au chocolat."

    17. JS

      [laughs]

    18. JI

      [laughs]

    19. JS

      That sounds amazing.

    20. JI

      No, it's 'cause the carbs were the only thing that didn't make me wanna throw up.

    21. JS

      But for first three months-

    22. JI

      Yeah

    23. JS

      ... you're okay.

    24. JI

      Well, the first three months you do what you can. If you're not nauseous, use everything in this book. And what I would say to pregnant moms is, okay, first trimester is kind of unique. Do what you can. Then I would say eat four eggs a day because four eggs are gonna give your baby all the choline that he needs. Two, make sure you have a protein at every single meal.

    25. JS

      Mm-hmm.

    26. JI

      This is gonna give your baby enough protein. Three, have fish or supplement with omega-3s. I did that every day. Two grams of omega-3s every day, which is more than you might think. And four, watch your sugar.

    27. JS

      Mm.

    28. JI

      Because cravings are strong during pregnancy.

    29. JS

      That's what I was about to say, so the cravings is not a myth. That's a real thing.

    30. JI

      Depending on who you are, you're gonna have different cravings. Like I was craving kiwis and red meat.

  7. 17:3219:24

    Are You Actually “Eating for Two?”

    1. JI

      et cetera.

    2. JS

      What are you actually eating for? That idea of you're eating for two, are you just eating for one? Like why, why is it... And if wife-

    3. JI

      You're eating for like 1.2.

    4. JS

      Right.

    5. JI

      So it's-

    6. JS

      So the double is a mistake because you could overdose on the sugar and-

    7. JI

      It's a total myth.

    8. JS

      Right.

    9. JI

      Like for example, for glucose, so glucose comes from carbs, so like bread, pasta, rice, or cake and fruit. Those are foods that contain glucose. They're called carbohydrates, carbs. You might think, "Oh, I'm pregnant. I need to eat like way more pasta, way more sugar." You don't. The studies show us that in the very end of pregnancy when your baby's about to be born, so he's as big as he's gonna get, he only needs a very small amount of glucose per day, 70 grams of glucose per day. That's about the amount of glucose in a cup and a half of rice.

    10. JS

      Mm.

    11. JI

      That's it. At the very end of pregnancy, you need one cup and a half of rice extra per day. And at the v- at the beginning of pregnancy you need no extra glucose. Second trimester, very little. So we need-... tell people about this [laughs] very important information. And you might think, Jay, "Okay, well, if a baby needs 70 grams of glucose, surely he just takes that and he doesn't take more."

    12. JS

      Mm-hmm.

    13. JI

      This is another misconception. Your baby does not just take what he needs. Your baby takes what is there. If there's more glucose in your bloodstream than he needs, he's gonna also register more glucose in his body than what he needs.

    14. JS

      Mm.

    15. JI

      So that's why we see that at birth some babies have super, super high glucose levels, and others have normal glucose levels, because it's all dependent on the mom's own glucose levels.

    16. JS

      Right.

    17. JI

      You're connected. You're connected. It's like if it's high in your blood, it's gonna be high in your baby's blood. If it's low in your blood, it's gonna be low in your baby's blood. If you don't eat any eggs or any choline whatsoever, your baby's not gonna get enough, and that's the whole point. You have to learn about this stuff, 'cause nobody's telling you, unfortunately.

  8. 19:2423:57

    You’re Born With the Brain Cells You’ll Keep for Life

    1. JS

      Yeah. I ca- I can't believe that this hasn't become necessary learning-

    2. JI

      Yeah

    3. JS

      ... in life. I remember people always talk about this idea of you go to the hospital, you give birth, and then you come home with a human being.

    4. JI

      [laughs]

    5. JS

      And there's no exam, there's no test-

    6. JI

      [laughs]

    7. JS

      ... there's no education. You know, we, we obviously have to take a driving test, right? We, we take exams to get jobs. It just feels like having a baby feels bigger and harder than all of those things.

    8. JI

      I think you'd think that because it's biological, you just know how to do it, and you'd think that society would naturally support it to the best of its abilities. But actually, the food around us today is failing moms.

    9. JS

      Celebrate your unique story with Pandora jewelry, crafted with meaning and exquisite artistry. I've learned that the most meaningful gifts aren't just beautiful, they carry a memory. When I think about gifting jewelry, I think about the women who've shaped my life. For Radhi, it might be a simple engraving that reminds her of who she is, even on the days she forgets.

Shop in store or online at pandora.net. If someone is eating a diet of processed foods, they're obviously not getting all these key markers, the four that you keep telling us. What's happening to that baby? What kind of nutrients is it getting?

    10. JI

      It's getting what it can. The mother's reserves are gonna be depleted-

    11. JS

      Right

    12. JI

      ... up to a point. There's a limit, 'cause biology will always favor the mom staying alive. So all of the mom's choline is gonna get given to the baby, but up to a point. The mom's muscle mass is gonna start shedding to give the baby protein. The mom's omega-3 reserves are gonna go all to the baby. But again, with a limit. Like, if you don't eat any of these foods, your baby will not get enough, quite simply.

    13. JS

      Mm.

    14. JI

      Um, and I mean, same with sugar, right? It's like if you eat a lot of sugar, your baby's gonna be processing a lot of sugar. Now, humans are resilient and nature has a way, and so the baby will probably be fine, probably.

    15. JS

      Mm.

    16. JI

      But you're silently setting up that baby for more vulnerability.

    17. JS

      Mm.

    18. JI

      You're silently programming his, his genes a bit more towards disease. You're probably shaping his brain in a way that's not optimal. For example, the brain. So today, Jay, you have about 100 billion neurons in your brain.

    19. JS

      Mm-hmm.

    20. JI

      Can you feel them?

    21. JS

      No. [laughs]

    22. JI

      [laughs]

    23. JS

      I hope they're there.

    24. JI

      So you have a- about 100 billion neurons, and these are the brain cells that connect information-

    25. JS

      Mm-hmm

    26. JI

      ... that process information. These are the same neurons that you had the day you were born.

    27. JS

      Wow.

    28. JI

      Neurons never get replaced. They stay with you from the moment you're born until you die.

    29. JS

      So they're getting older.

    30. JI

      They're getting older. And most importantly, all your neurons, give or take 5%, were created when your mom was pregnant with you, and choline and omega-3s are super important to creating those neurons. And so depending on how much choline and omega-3s your mom was having, your brain will be shaped differently. In the studies done on animals, again, 'cause we can't do this in humans, scientists will reduce the amount of choline and omega-3s in the mom's diet. And then when the baby's born, they look at the brains very, very closely under the microscope and they see that if there's very low levels of choline, the babies have fewer neurons and a smaller brain.

    When Food and Supplements Work Best Together

    1. JS

      Do you recommend people getting those from supplements or from food? And what does that look like?

    2. JI

      Food is always better absorbed and always cheaper.

    3. JS

      Right.

    4. JI

      However, if you don't eat any animal foods, you should take the supplements. It's just gonna be much easier. For example, choline. So four eggs a day is the amount you need, um, for your baby. If you're vegan, that would mean you have to eat eight pounds of soybeans per day. Eight pounds-

    5. JS

      Mm

    6. JI

      ... to get enough choline.

    7. JS

      Yeah.

    8. JI

      So take a supplement.

    9. JS

      Yeah, right.

    10. JI

      It'll be way, way easier.

    11. JS

      Yeah.

    12. JI

      Way easier.

    13. JS

      Right.

    14. JI

      For omega-3s, you can only find them in fish-

    15. JS

      Yeah

    16. JI

      ... or in algae or krill. So if you're vegan, you wanna take, um, some supplements made from algae.

    17. JS

      Mm-hmm.

    18. JI

      Now, I still supplemented with extra omega-3s and extra choline.Just because

    19. JS

      Just to be safe

    20. JI

      I wanted to put as much as I could there.

    21. JS

      Yeah.

    22. JI

      But supplements are great, but again, like, if you're only supplementing, the molecules are still gonna be a bit less well-absorbed than if you take the real food.

    23. JS

      Is there any way of knowing whether all of what you did has helped your son?

    24. JI

      I mean, he's wonderful.

    25. JS

      Yeah.

    26. JI

      He's very smart.

    27. JS

      Yeah.

    28. JI

      Super awake, like, uh, éveillé, which means, like, just, you know.

    29. JS

      Yeah.

    30. JI

      He's, he's really present. Is there any way I could know? I don't think so.

  10. 26:3030:03

    Avoid These Foods During Pregnancy!

    1. JS

      What are the foods that mothers when they're pregnant need to avoid?

    2. JI

      Well, I would say the classic ones. So alcohol is one. There was some debate a few years ago around, oh, maybe alcohol is not that bad. The thing is, when you understand how the biology of it all works, if you drink a glass of wine when you're pregnant and your blood alcohol level goes up, your baby's blood alcohol level in your uterus also goes up by the same amount. So when people say, "Oh, a glass of wine is fine during pregnancy", I'm like, "When your baby's born, would you give him red wine in his bottle? No." You're doing the same thing.

    3. JS

      That's crazy.

    4. JI

      Yeah, it's crazy.

    5. JS

      And what impact does that have?

    6. JI

      Well, we know that very high alcohol levels can lead to proper, proper, proper health conditions with babies born with a lot of disability, but the one glass a day, we don't really know. It seems to be fine, but what's happening in the brain, we're not sure. In animal studies, they s- they show that even the equivalent of one glass a day leads to the brain forming differently than it should. So that's one thing. Another thing to avoid, I mean, cigarettes, all drugs, toxic chemicals if you can, because again, they go into your baby's bloodstream.

    7. JS

      What kind of toxic chemicals are the ones we don't think about? The ones that you had to really clear out.

    8. JI

      Hmm, that's a good question. I think the big ones is, like, asbestos, mold, um-

    9. JS

      Cleaning products in the house?

    10. JI

      ... pesticides. So there's no studies on those-

    11. JS

      Okay

    12. JI

      ... but, yeah, probably. It's a good idea. I try to clean everything with vinegar. [laughs]

    13. JS

      Yeah. [laughs]

    14. JI

      I either drink it or I clean with it.

    15. JS

      Yeah.

    16. JI

      Uh, that's a good idea. I also was very careful with plastics. So I was wearing Invisaligns, you know-

    17. JS

      Mm-hmm. Mm-hmm

    18. JI

      ... the teeth retainers? And I took them out during pregnancy because I saw some studies that show that there's minuscule amounts of plastic that can be leaching into your body, so I thought might as well be safe. But again, this is very early stuff.

    19. JS

      So even drinking from a plastic water bottle, for example.

    20. JI

      I try to avoid that.

    21. JS

      Yeah.

    22. JI

      For myself also, 'cause the microplastics.

    23. JS

      Yeah.

    24. JI

      You wanna avoid heating plastic in the microwave or eating out of a warm or hot plastic container. Plastic bottles are a big, big one, so I ha- I, I lose it all the time, but I buy a nice aluminum water bottle, and then I lose it after four days-

    25. JS

      [laughs]

    26. JI

      ... and I have to buy another one.

    27. JS

      Yeah. Yeah. Yeah.

    28. JI

      But I try to drink out of those, for sure.

    29. JS

      Yeah. Wow.

    30. JI

      And then the big one we don't think about is, like, sugar. That's something that goes directly into your baby's bloodstream that your baby also has to deal with. So I did all this work on glucose, right?

  11. 30:0335:34

    How High Sugar Intake Affects Pregnancy

    1. JS

      And what's that training the baby's body to do?

    2. JI

      Well, it does exactly what you do, meaning it registers inflammation, and it also has to deal with the spike.

    3. JS

      So it has to crash.

    4. JI

      Yeah, and it has to turn the glucose into fat to manage the spike. So your baby's body as he's developing is like, "Oh, glucose spike. Okay, I'll take some glucose that I need, but the glucose I don't need, I'm gonna store it as fat." And that's why we see that baby's fat mass at birth is perfectly correlated to the mother's glucose levels.So the higher your glucose levels during pregnancy, the more fat mass your baby is born with

    5. JS

      And the most baby's really cute.

    6. JI

      So-

    7. JS

      Yeah

    8. JI

      ... absolutely.

    9. JS

      Yeah [laughs]

    10. JI

      Super cute.

    11. JS

      [laughs]

    12. JI

      But if there's a lot of fat, it's a sign that your baby had to deal with-

    13. JS

      Right

    14. JI

      ... a very high glucose environment when he was in your belly.

    15. JS

      Are they taking energy away from other areas of growth-

    16. JI

      Mm

    17. JS

      ... by having to process that?

    18. JI

      That's a great question. I don't know if they're taking energy away, but the main thing that's going on is that repeated glucose spikes is increasing inflammation.

    19. JS

      So it's setting them up for having in- inflammatory body long term.

    20. JI

      It's doing a few things. Yes. One thing, yes. Second thing is it's training their body that to, to put on fat.

    21. JS

      Mm-hmm.

    22. JI

      Like put on fat, put on fat, put on fat so that you know how to store glucose away quickly. And so in animals, we see that high sugar diets during pregnancy means that the babies have these switches activated on the genes for storing fat.

    23. JS

      Mm.

    24. JI

      So they are set up, they're calibrated to be really good at storing fat. And we all have friends who eat the same diet as another friend, but one friend puts on much more weight than the other.

    25. JS

      Yeah.

    26. JI

      And then the other thing that happens, Jay, has to do with your baby's brain, and this is an entire incredible universe. So as I said, all of your neurons are being built during pregnancy, and so you have the neurons in your brain. Pew, pew, pew. Lots of neurons being created. Da, da, da, da, da, da, da.

    27. JS

      [laughs]

    28. JI

      250,000 neurons per minute during pregnancy. Da, da, da, da, da, da. Okay, but that's not all. In your baby's brain, there's also another type of cell, and these cells are called the microglia. And they kind of look like starfish. They're like, "Hello, [laughs] I'm a microglia" And they are sort of your baby's rangers. They're in your baby's brain as he's growing his brain. And they detect problems. They say, "Oh, that neuron is not shaping out as it should. I'm gonna go grab it-

    29. JS

      Mm-hmm

    30. JI

      ... and destroy it." "Mm, that neuron is not connecting very well, or it looks a bit weird. I'm gonna go grab it and destroy it."

  12. 35:3438:24

    The Modern Food System Is Failing Families

    1. JS

      How do you encourage moms to think about the stress component of this or which I'm sure you had to navigate yourself?

    2. JI

      Yeah. I think the first thing we need to understand, this is not the mom's fault.

    3. JS

      100%.

    4. JI

      100%.

    5. JS

      Yeah.

    6. JI

      Society has, excuse my language, fucked up the food that is available today, the food that is cheap, the food that's at the grocery store, the food that they serve you, uh, even at the hospital, is bad for us, and it's leading to all sorts of stuff, from heart disease to diabetes. I mean, peop- we're all sick because of our food system, and it's also failing pregnant moms.

    7. JS

      Mm.

    8. JI

      Like, it's failing everybody else.

    9. JS

      Yeah.

    10. JI

      And so just like with everything else, we have to say, "Shit, we are in a bad situation. The food around us is not helping us. What can I do? What are small things I can do to try to put the odds back in my favor?"

    11. JS

      Mm.

    12. JI

      And just like with my glucose hacks, I teach people how to, you know, uh, reverse diabetes, for example. Here I'm like, "Okay, ladies, we're in a bad situation. Society is not helping us. Here are simple things that we can do to help us navigate this food landscape during pregnancy." And Jay, it is a lot of pressureLike, you're building a human, and I'm never gonna be able to take that pressure away. I felt it too.

    13. JS

      Mm.

    14. JI

      But I'm hoping that with this book, I'm gonna lead moms away from, like, the overwhelming Instagram information-

    15. JS

      Yeah

    16. JI

      ... and that barrage of, like, stuff, and be like, "These are four things that if you do them, you're gonna have an outsized positive effect on your baby's development-

    17. JS

      Yeah

    18. JI

      ... and long-term health."

    19. JS

      Yeah, it's just four things, yeah.

    20. JI

      It's stressful. It's so stressful to be pregnant because no matter what you do... And even now that I have my baby who's born, I feel like no matter what I do, I'm, I could have done it better. I, I'm gonna feel guilty of this, guilty of that. Like, it's tough. It's tough. But if we go back to science and we go back to simple stuff that has a big impact, I truly believe we can navigate that pressure with a bit more ease and serenity.

    21. JS

      And I appreciate you saying it's not, you know, the woman's fault because-

    22. JI

      Biologically-

    23. JS

      Yeah

    24. JI

      ... Jay-

    25. JS

      Yeah

    26. JI

      ... babies are developing in female bodies, and that's just biology.

    27. JS

      Yeah.

    28. JI

      But everybody is responsible for the society we live in.

    29. JS

      Yeah.

    30. JI

      We're not gonna hold moms responsible for the food at the grocery store.

  13. 38:2440:43

    What Can Contribute to Miscarriage

    1. JS

      is there also a connection between... And, and I'm asking because I genuinely don't know. Is there a connection between diet and miscarriage?

    2. JI

      Mm. So for a few core things, so folic acid is one, so that's why doctors will always tell you to take a folic acid supplement because if you have very low levels, then miscarriage is more likely. But choline is also associated with miscarriage when it's too low, and that's something people don't talk about. And listen, I was eating choline, I was taking my folic acid supplement, and I still had a miscarriage. So you can do your best, but some things are completely out of your control-

    3. JS

      Mm

    4. JI

      ... for sure. For sure. And the flip side of that is that even if you do nothing that's in this book, even if you've had kids before, they're probably gonna be okay. We're talking about small optimizations. We're talking about, as you, as you saw, like 3% to 4%, small stuff. I'm fine. You're fi- you're fine. Our moms didn't eat any choline, omega-3s, ate a lot of sugar. We're okay. Humans are resilient. But if we know this, we need to tell people about it.

    5. JS

      Yeah, and, and I think it's also as you grow older, you actually start to realize [laughs] how much all these things matter more-

    6. JI

      Mm

    7. JS

      ... when it comes to long-term health.

    8. JI

      Like the vulnerability, you mean?

    9. JS

      Yeah, like mental health. Like, you don't realize this in your 20s or when your kid's a teenager when, you know, your body's doing all the best work. But when you hit your 40s and your 50s and people go on, that's when you start to notice, oh, I've had inflammation in my body for years, people with mental health conditions that are based on that. You've-- When you look at all the impacts, like, I appreciate what you're saying, that humans are resilient, we'll survive, but the reality also is that you start to see the vulnerabilities and the cracks in the body and the mind as we get older that you don't appreciate when your kid's young and everything generally-

    10. JI

      Totally

    11. JS

      ... hopefully feels healthy and touch wood. I really appreciate you, uh, sharing your own experience because I'd say pretty much like 75% of my friends who've tried to conceive in the last 24 months have experienced at least one miscarriage, if not more, and I feel like it's an area that isn't talked about enough. It isn't shared enough unless you really are really close friends with quite a lot of people. And there seems to be at least some pain, and maybe there's even guilt and shame attached to it for many mothers that I've spoken to. Talk to

  14. 40:4345:48

    Understanding Silent Miscarriage

    1. JS

      me about the fact that you thought you were doing everything right, and then you go through that. What is, what is that experience like?

    2. JI

      So I'll take you back to the beginning.

    3. JS

      Mm-hmm.

    4. JI

      So I'll tell you the whole story. So my husband and I decided to try to have a baby. This was two years ago or something. And I got pregnant really quickly, in two months, and I had no, no cares in the world. I was just very nauseous, but I, I, I thought everything would be fine. So we go to the first ultrasound, and they find a heartbeat. I'm like, oh my God, great. My baby's gonna be born in December. How wonderful. Oh man, we've gotta move now. You get into the process. I go back at the three-month mark for the next ultrasound to check everything's fine, and I get to the doctor's office and I lay down, and they put this gel on your belly, and then they put this weird wand thing, like-

    5. JS

      Yeah

    6. JI

      ... to see inside your belly. And there's, there was a screen in front of me that showed me the image in real time of what he was seeing. So he put the thing on my belly, turned the machine on, the image popped up on the screen, and I just, I just knew instantly that there was a big problem. The embryo on the image had not grown, and it was... This is kind of a crude image, but it was sort of laying at the bottom of my uterus, a little bit like you would see a dead fish at the bottom of an aquarium. Like, I could see that it was lifeless. And just this, the ground was ripped out of under my feet, you know? I was like, "Oh my God, the embryo is dead." I had experienced what's called a silent miscarriage, silent being the key word here, meaning I had no symptoms. Most people when they have a miscarriage, they start bleeding. They have cramps, and the body expulses the embryo. I had no symptoms. I had been walking around for a month with a dead embryo, 'cause they can see when it stopped developing, and I had no clue.

    7. JS

      Mm.

    8. JI

      No idea. It was so freaking painful.So I needed to have a surgery where they take the embryo out, which was terrible, and it brought back all this trauma-

    9. JS

      Yeah

    10. JI

      ... of my back surgery. It was just so bad. And then I, I just spiraled, and I think I saw you, like, two weeks after, and I was like, "Jay, I'm really not okay." And I felt like if emotions could kill me, I'd be dead. That's the intensity I was feeling. 'Cause it's not just like you lost a pregnancy. It's you lost the entire narrative. You lost the life that you had projected and planned. All of a sudden, oh, in December I'm not gonna have a baby. It's so rough, and you're s- I was so scared. Am I gonna be able to get pregnant again? Is this gonna happen again? All of a sudden, all my friends were pregnant around me, and they were fine. You know? It's just like all of a sudden everybody was pregnant on Instagram. I felt so, so, so sad, and I felt so angry, and I didn't understand why it had happened to me. I was like, "Why me?" And then I started talking to my friends and family. I found out that my mom had had miscarriages, and she had never told me. My stepmom, my grandmother, my closest friend. All of a sudden, the tongues untied. But because I didn't know about these stories beforehand, I was not prepared.

    11. JS

      Mm.

    12. JI

      I had no clue that this could happen to me, therefore, I fell from so, so high. I even told people I was pregnant the day I got the positive pregnancy test. Usually you wait until three months because that's when you know it's probably gonna be okay. I was like, "Oh my God, pregnancy test positive." I called up everybody, "Oh my God, I'm having a baby." I had no conception, and I'm somebody who, I consider myself pretty well informed.

    13. JS

      Mm.

    14. JI

      But yet I, I was, I was so lost. And then the grief was so deep and so painful. But yet at the same time, I wanted to try getting pregnant again, and I was asking myself, "Do I have to have fully grieved this pregnancy before I allow myself to have another pregnancy?"

    15. JS

      Mm.

    16. JI

      And then I realized that that grief was always gonna be there and coexist. I was never gonna be able to completely say goodbye to it. So we tried again. I got pregnant again, and then followed the most stressful nine months of my life because every day I thought-

    17. JS

      Yeah

    18. JI

      ... maybe there's a problem and I don't know.

    19. JS

      You wake up with that feeling. It's the worst.

    20. JI

      'Cause for the first four, five months, you don't feel the baby. So I was just spiraling. I went to the doctor so many times. I was so embarrassed, wanting-- I wanted so many ultrasounds-

    21. JS

      Of course

    22. JI

      ... that I started seeing two different doctors, and they didn't know about each other 'cause I felt so-

    23. JS

      You're cheating on them [laughs]

    24. JI

      ... embarrassed of how much I wanted to get ul-

    25. JS

      Of course

    26. JI

      ... I got, like, 10 ultrasounds in the first three months, four months. 10. Usually you get, like, two. So anyway, it was terrible, and it was really, really, really painful. Um, and then when my son was born, I felt like I wasn't anxious anymore [laughs] 'cause I was like, "Okay, he's here. He's alive. He's okay." But it was an awful experience, and I wish that more people had told me about their own miscarriages-

    27. JS

      Mm

    28. JI

      ... so that I felt a bit less alone. I would even fi- I would go on Google and be like, "Celebrities who have had miscarriages," and I saw, oh, Beyoncé had a miscarriage. Okay, I feel less alone now.

    29. JS

      Yeah, yeah.

    30. JI

      That's how much I wanted connection.

    Processing the Grief of Pregnancy Loss

    1. JS

      Gabrielle Union's talked about it at length, her experiences of multiple and just... Yeah. It's, it's, uh, gosh, I mean, it's, you know, i- it's, it's one of those things that, like, it doesn't matter how, even how common it is. It's like the loss and the grieving and the experience of it is so heavy.

    2. JI

      And few people know how to hold space for it.

    3. JS

      Talk to me about that.

    4. JI

      You're grieving. You're properly grieving, and I think it's one of the only griefs that people don't know how to manage.

    5. JS

      Yeah.

    6. JI

      Usually when grief comes up in life, we kind of know what to do. We check in with the person. We say, "Are you okay? Do you want me to come over?" With miscarriage grief, it feels different 'cause it's invisible.

    7. JS

      Mm.

    8. JI

      Nobody physical died.

    9. JS

      Mm.

    10. JI

      And so I got a range of responses from people saying, "Oh, it's just nature doing its thing. Don't worry," to people saying like, "Okay, well, just move on, and, you know, it'll work next time." It was like, you don't understand. It's not about that. And then there were amazing people who also just knew to just hold it. But it makes-

    11. JS

      Yeah

    12. JI

      ... it, it makes a lot of us very uncomfortable 'cause we don't know how to handle it. And all you really, all I really wanted was just people to say, "I'm so sorry. This must be so hard."

    13. JS

      Yeah, of course.

    14. JI

      "Can I bring you a chocolate cake?"

    15. JS

      [laughs]

    16. JI

      That's all I wanted.

    17. JS

      Yeah. Yeah.

    18. JI

      So you, it's just like, it's just like any emotion.

    19. JS

      Yeah.

    20. JI

      You want it to be held better, but we're not educated. I mean, you do great work to help people know how to, how to deal this with emotion and hold it, but yeah, it's, uh, it's rough.

    21. JS

      Yeah. It's, it's shocking to me that people even still think they can say things like, "Oh, well, just move on. It'll work out." Like, I- and I get it. It's coming from a good-

    22. JI

      They wanna be positive

    23. JS

      ... Totally.

    24. JI

      Yeah.

    25. JS

      It's coming from a good place.

    26. JI

      Yeah.

    27. JS

      But it's like, I think we're so far past the thinking that positive outpaces-

    28. JI

      Yeah

    29. JS

      ... like, an-

    30. JI

      Yeah

  16. 48:2851:10

    The Most Common Causes of Miscarriage

    1. JI

      you know?

    2. JS

      Is there any research to suggest what causes a miscarriage is? Does anything exist?

    3. JI

      Yeah. SoYou kinda see these pie charts that show you the percentage likelihood. So maybe it's a nutritional deficiency, like folate or choline. Maybe it's a chromosomal abnormality, meaning that the chromosomes in the sperm and the egg were slightly messed up. And as you age, your eggs and your sperm have more abnormalities-

    4. JS

      Mm

    5. JI

      ... which is why miscarriage is more common as you advance in age.

    6. JS

      Mm.

    7. JI

      So maybe my egg had a chromosome that was missing or a problem. Maybe my husband's sperm had a problem in his chromosomes. We don't know.

    8. JS

      Right.

    9. JI

      But in a way, it's, quote-unquote, "good" because a miscarriage means that embryo is probably not viable.

    10. JS

      Right.

    11. JI

      Other reasons could be your placenta, which is, um, the, the organ that helps grow the baby. Maybe there was an issue there. Maybe your body was not able to hold onto the pregnancy, and it's probably a lot of stuff that we don't even know about.

    12. JS

      Mm-hmm.

    13. JI

      But in most cases, you can't control it, and so that's why it's, um, it's stressful.

    14. JS

      Yeah.

    15. JI

      Mm.

    16. JS

      Yeah, yeah, absolutely. I, I can't imagine it. I mean-

    17. JI

      You have to hold it lightly, you know?

    18. JS

      Yeah.

    19. JI

      And my therapist said something amazing. So when I was pregnant with my son, so my second pregnancy, and I was, like, four months in, and I was still super stressed. I was like, "Well, what if I miscarry? B- what if I lose him?" And she was like, "You don't know how long you're gonna have this baby. But for as long as you have him, you can choose to love him."

    20. JS

      Mm.

    21. JI

      Because I was even keeping myself from love and from joy during my second pregnancy until, like, the fifth-month mark because I was so anxious.

    22. JS

      Mm.

    23. JI

      I didn't wanna reopen my heart-

    24. JS

      Yeah, yeah

    25. JI

      ... 'cause I was so scared.

    26. JS

      That's real.

    27. JI

      And after she said that, I was like, "Okay, you know what? Yes, I can allow myself to love."

    28. JS

      Yeah.

    29. JI

      And love is vulnerable.

    30. JS

      Mm.

  17. 51:1053:54

    What Happens When You Eat Sugar on an Empty Stomach

    1. JS

      thing you raise as challenges for moms in their nine months is fatigue.

    2. JI

      Mm-hmm.

    3. JS

      And, you know, we've been talking about stress somewhat, and that's how we went off in this direction. But that fatigue-

    4. JI

      Oh

    5. JS

      ... that you get by being pregnant, and that naturally wants you to have sugar, and that naturally wants you to have carbs and fat, like, all the stuff-

    6. JI

      Yeah

    7. JS

      ... that we're trying to... So, like, what do you do when you're tired?

    8. JI

      Well, I totally get it. I was there too. And what's interesting about the sugar is that you think it's giving you energy. It's actually not. It's giving you dopamine.

    9. JS

      Mm.

    10. JI

      Dopamine is the pleasure molecule in your brain, so you feel kind of awake, like, "Whoa, I'm awake."

    11. JS

      [laughs]

    12. JI

      You think it's energy. It's not.

    13. JS

      Yeah.

    14. JI

      But it's okay because sugar helps us feel better, and I totally am there. I was there too. So what I did is I always made sure to not have sugar on an empty stomach.

    15. JS

      Mm-hmm.

    16. JI

      Why? Because this is gonna create a big spike and a big drop and more fatigue.

    17. JS

      Mm-hmm.

    18. JI

      And it's gonna create a big spike that's also gonna go into my baby's bloodstream. So always sugar after a meal. Never for breakfast, for example. And if I... I felt, sometimes I felt really, really hungry. Like, I was just like, "Wow, I need to eat so much today," and that was probably my body telling me, "You need more food." So I would eat spaghetti. I would eat all the carbs I wanted. But again, I would do that in certain ways. So for example, I would always have the carbs after a veggie starter built around vegetables-

    19. JS

      Mm

    20. JI

      ... because the fiber in the veggies creates this protection in your intestine, and it slows down how quickly glucose arrives into your bloodstream.

    21. JS

      Wow.

    22. JI

      So I was like, I'm gonna eat the carbs that I'm craving, but with the hacks-

    23. JS

      Mm-hmm

    24. JI

      ... so that I reduce spikes and inflammation in my body and in my baby's body.

    25. JS

      Mm-hmm.

    26. JI

      And all this is in the chapter in 9 Months That Count Forever about blood sugar and glucose. And you can use all of the hacks around my glucose work except one, which is vinegar. So if you do wanna do the vinegar hack during pregnancy, you have to make sure that it's pasteurized because you wanna make sure that it's safe to consume for you and your baby. And the hack is the following. You take one tablespoon of vinegar in a big glass of water before you eat carbs, and this can reduce the glucose spike by up to 30%.

    27. JS

      Yes, this is your, your magic formula.

    28. JI

      And the thing is here, what it does, it just slows down how quickly glucose arrives in your bloodstream-

    29. JS

      Mm

    30. JI

      ... 'cause it slows down the digestion of the carbs. So it's not erasing the carbs. It's fine to have carbs, and as I mentioned, your baby needs more carbs as pregnancy progresses. But it's helping them arrive more calmly-

  18. 53:5456:37

    The Importance of Movement During Pregnancy

    1. JS

      to know, that women listening need to know?

    2. JI

      [sighs] Well, if you feel like moving, even just going for a quick walk can be super helpful. Not only does it help with your blood sugar levels, but-

    3. JS

      I still walk for 10 minutes after eating dinner every night

    4. JI

      ... Nice.

    5. JS

      Yeah.

    6. JI

      That's amazing.

    7. JS

      Yeah.

    8. JI

      But during pregnancy, exercise seems to be doing something incredible.

    9. JS

      Mm.

    10. JI

      So this is one of my favorite studies, okay, that I discovered about pregnancy. So scientists took two groups of rats. They, both groups were pregnant, and they put them in the same houses, same diet, same lighting, everything. The only difference was one group of rats had these tiny little treadmills, and they had to walk on the treadmill for 30 minutes a day every day during their pregnancy. The other group did not do any exercise. That was the only difference. Then the babies were born-And the scientists put the babies in these mazes, and they measured the babies' anxiety levels. They found that the babies from the moms who exercised solved the mazes twice as fast-

    11. JS

      Wow

    12. JI

      ... and had 80% fewer anxiety symptoms.

    13. JS

      No way.

    14. JI

      The only difference was the physical activity during pregnancy.

    15. JS

      That's crazy.

    16. JI

      So even if you just walk, it's gonna help your glucose levels and gonna help probably your baby's brain development.

    17. JS

      Those 10,000 steps.

    18. JI

      I mean, listen-

    19. JS

      [laughs]

    20. JI

      ... when you're pregnant, one step feels like 10,000 steps.

    21. JS

      Yeah, yeah.

    22. JI

      So we-

    23. JS

      So what's realistic?

    24. JI

      Do what you can.

    25. JS

      Okay.

    26. JI

      Do what you can. I loved walking. I was... Personally, I went and weight lifted at the gym [laughs] up until, like, my eight and a half month of pregnancy, and it was very hard, but it felt good after I was done.

    27. JS

      Wow.

    28. JI

      That's the only thing I could do all day. I was like, "Okay, I'm going to the gym today," and I would just muster up all my courage with my big belly. And I was living in Montmartre in Paris, which is very, uh, on top of this hill, and I was living in this apartment which was a fifth story walk-up.

    29. JS

      Oh my God.

    30. JI

      Yeah, so I moved when I was eight months, but before that, I just naturally was in a situation [laughs] where I had to walk all the time.

  19. 56:3757:14

    How to Reduce Bloating During Pregnancy

    1. JS

      do pregnant moms do if they're experiencing a lot of bloating?

    2. JI

      Mm. That's a very good question. I think some of the bloating is hormonal, especially in the first trimester.

    3. JS

      Mm-hmm.

    4. JI

      Um, and then probably similar stuff as you would do the rest of the time. So counterintuitively, you actually wanna have more fiber.

    5. JS

      Mm.

    6. JI

      Um, sometimes if you increase fiber very quickly, it's gonna lead to a lot of bloating, so you wanna make sure you're doing that slowly. And then honestly, sugars is a big one. If you reduce your sugar intake, generally bloating goes down.

    7. JS

      Mm.

    8. JI

      And then sometimes you have food sensitivities that can increase bloating also, uh, but that's a big topic, yeah.

    9. JS

      Mm. One thing we haven't talked about,

  20. 57:1458:31

    Does a Father’s Diet Affect Conception?

    1. JS

      before we get into a game we made for you, uh-

    2. JI

      A game?

    3. JS

      Yeah. [laughs] Uh, one thing we haven't talked about is how does the man's diet affect his sperm and affect... You know, we, we touched on it briefly when we were talking about-

    4. JI

      Yeah

    5. JS

      ... miscarriages, but, like, how, how important is that? How valuable is that?

    6. JI

      So the man's diet before conception is gonna set up his sperm quality.

    7. JS

      Yeah.

    8. JI

      For sure. We know that. The problem is, from the moment conception happens, the entire responsibility of the diet is in the female body.

    9. JS

      Yeah, of course.

    10. JI

      For example, so women have these eggs, right? And the sperm me- meets the egg. The sperm only brings DNA. He's not bringing anything else. The egg is 10,000 times bigger than the sperm because it contains DNA and also food. So the mom's diet is more important to the development than the dad's diet.

    11. JS

      Mm.

    12. JI

      The dad's diet is important preconceptions. For example, my husband, three months before trying to get pregnant both times, he cut out all alcohol. He was exercising a lot. He was really careful with his sugar. He did all of that, and then he kinda threw me the ball, and I was in charge. [laughs] But it is helpful for the dad-

    13. JS

      Yeah

    14. JI

      ... to have a healthy lifestyle, especially preconception.

    15. JS

      Yeah. It's just, I feel like none

  21. 58:311:00:47

    Using Food to Set Your Child Up for Life

    1. JS

      of this is ever talked about.

    2. JI

      Yeah.

    3. JS

      Like, we almost, like, just have kids without thinking about it, and there's no-

    4. JI

      And listen, it works, right?

    5. JS

      Yeah, yeah.

    6. JI

      Like, it works.

    7. JS

      Yeah, yeah.

    8. JI

      But if, in a world where we have all these incredible scientific studies-

    9. JS

      Yeah

    10. JI

      ... we need to know about them.

    11. JS

      It works, but I also think we're noticing long-term the ramifications of-

    12. JI

      That's the thing.

    13. JS

      Yeah.

    14. JI

      Like, let me make you a little list of my problems.

    15. JS

      Yeah.

    16. JI

      So I have a unhealthy obsession with cats. [laughs]

    17. JS

      [laughs] No, I don't think that's a problem, is it?

    18. JI

      You know, I have existential crises all the time.

    19. JS

      Yeah.

    20. JI

      Lots of mental health issues, depersonalization, dissociation, anxiety, depression, cusp of prediabetes when I was 25, like, I was two points away from prediabetes, um, problems with emotional regulation, like, emotions can really overwhelm me. I am really bad at running fast. I mean, the list goes on, okay? Some of these things, maybe they're genetic. Some of these things, maybe they have to do with my mom's diet in the womb. Maybe they have to do with my child e- child experiences, like, who knows? But for sure, the nine months of pregnancy calibrate things. They're a window of outsized influence.

    21. JS

      Yeah.

    22. JI

      And so today, I'm, after knowing about all the science, I'm certain that my mom's diet, if it had been slightly more higher in choline, omega-3s, protein, and lower in sugar, I'm sure that I would feel different today.

    23. JS

      Yeah.

    24. JI

      And the-

    25. JS

      And those are all doable. They're practical.

    26. JI

      Exactly.

    27. JS

      They make sense.

    28. JI

      Exactly.

    29. JS

      And add on the couple of hacks that you just mentioned.

    30. JI

      So what's wrong with you now? Let's make a list.

  22. 1:00:471:04:02

    What the UK Sugar Ration Taught Us About Health

    1. JI

      is important.

    2. JS

      Yeah. What's a study that hasn't been done?That you'd wish we could do to understand pregnancy better

    3. JI

      It would be very unethical. If we really wanted to measure the impact, we would recruit 1,000 women, and half of them we would say, "Eat what you normally were gonna eat. Don't worry about it." And the other half, we would make sure that they're getting all the nutrients I talk about in this book, and we would supplement them and give them all the choline, all the protein, all the omega-3s. We would make sure they're below the WHO recommendation for sugar. And then the babies come out, then we would follow them for 30, 40, 50 years, and we would see what happened.

    4. JS

      Hmm.

    5. JI

      Actually, while this is impossible, something happened in the UK that was kind of close.

    6. JS

      Hmm.

    7. JI

      Do you know about this?

    8. JS

      No.

    9. JI

      Okay.

    10. JS

      No idea.

    11. JI

      So from 1940 to 1953 in the UK, there was a sugar ration, meaning the government reduced the amount of sugar that everybody could eat on a daily basis. People had a ration, an allowance. Everybody had 40 grams of sugar allowed per day. This was during the war, and it was a way to manage resources. So everybody got 10 sugar cubes a day. That's it. Moms, grandparents, pregnant moms, everybody, 40 grams of sugar per day. This lasted 13 years. Then all of a sudden, the ration was lifted. People went back to eating what they usually ate, which meant 80 grams of sugar per day. So all of a sudden, everybody in the UK went from 40 grams to 80 grams of sugar per day. And scientists in the early 2000s were like, "Huh, this is really interesting," because this means that we have babies who were developing when pregnant moms ate 40 grams of sugar, and then just after, we have babies developing when moms were eating 80 grams of sugar during pregnancy. And the scientists wondered if they could see any differences in the babies' health, 'cause the only thing that had changed was the amount of sugar.

    12. JS

      Sugar, yeah.

    13. JI

      So they called up... Well, they found the medical records, and they called 60,000 people, and they saw that the babies who were developing when sugar was lower had a 15% lower likelihood of having developed type 2 diabetes in their lifetime-

    14. JS

      Wow

    15. JI

      ... compared to their peers who were developing and born after the sugar ration, who had a higher likelihood of diabetes. So what does this mean? It means that reducing our sugar intake during pregnancy is associated with lifelong benefit-

    16. JS

      Mm-hmm, mm

    17. JI

      ... less vulnerability to diabetes lifelong in your baby for their entire life.

    18. JS

      Yeah.

    19. JI

      And the only change was the number of sugar cubes per day.

    20. JS

      [laughs]

    21. JI

      Isn't that amazing?

    22. JS

      Yeah, yeah, absolutely.

    23. JI

      Today, most moms eat 80 grams of sugar per day, which is the level that was shown to have higher diabetes risk.

    24. JS

      Hmm.

    25. JI

      The WHO recommends 25 grams, which is lower than the sugar ration. So even if you just look at your diet during pregnancy, you're like, "Okay, I'm gonna try to just reduce by even 5 grams-

    26. JS

      Yeah

    27. JI

      ... 10 grams-

    28. JS

      Yeah

    29. JI

      ... one sugar. Instead of having an orange juice, I'm gonna have a whole orange." That's 20 grams of sugar gone. Just these small tweaks can have an outsized impact-

    30. JS

      Yes

  23. 1:04:021:10:51

    This or That: Pregnancy Edition

    1. JS

      came up with a This or That game for you, Pregnancy Edition.

    2. JI

      Okay, I love it.

    3. JS

      This was inspired by your book, 9 Months That Count Forever, and so it's dedicated to you and your book. So Jessie, this or that, because you did the final five last time. So question number one, carbs first or protein first when you're nauseous?

    4. JI

      Oh, protein first. Protein all the time. It will, it will help a lot.

    5. JS

      Okay. Small frequent snacks or fewer, more balanced meals?

    6. JI

      Ugh. If you're very nauseous, the small frequent ones really, really helps. I was eating an almond every five minutes, basically. [laughs]

    7. JS

      [laughs]

      But ideally, it's always gonna be better to have bigger meals. But also, as you get more pregnant, as pregnancy progresses, your stomach gets smaller, so because your uterus is pushing on it, so you have to eat smaller meals.

    9. JS

      Yeah.

    10. JI

      So it's not a huge deal. Just make sure that you're eating the right stuff, like the protein and the fish and the eggs. [laughs]

    11. JS

      Very useful. Good advice. All right. Morning sickness the entire pregnancy or intense cravings?

    12. JI

      Like, what do I prefer?

    13. JS

      Yeah. [laughs]

    14. JI

      [laughs] Cravings. [laughs]

    15. JS

      [laughs] Pushing through nausea to eat for nutrients or meeting your body where it is?

    16. JI

      Oh, come on. That's easy. Meeting your body where it is.

    17. JS

      [laughs] We're just checking. We're, you know, we like trying to help everyone out. Uh, following strict pregnancy food rules or reducing stress around food?

    18. JI

      Mm. Reducing stress around food and knowing that by doing these four key things, you're helping your baby a lot.

    19. JS

      More rest or gentle daily movement?

    20. JI

      Ooh, both, if you can. [laughs]

    21. JS

      [laughs] Strength training or cardio during pregnancy?

    22. JI

      Ooh, great question. Whatever you do. Whatever you can do.

    23. JS

      Okay.

    24. JI

      Yeah, both are great, so do the one that you can do.

    25. JS

      And you, you said you were doing weight training.

    26. JI

      Yeah.

    27. JS

      That was what you were doing.

    28. JI

      Yeah, yeah.

    29. JS

      Yeah. Eating within an hour of waking or waiting until appetite kicks in?

    30. JI

      Oof. Depends on the nausea.
