Quick-Fire Round: Salt, Sugar, and Marketing Myths
- TNTrevor Noah
[upbeat music] Wait, there's a, there's a list of ingredients, basic ingredients that, uh, people always interact with or always have in their homes that they might not be sure if they're good or bad, including myself. So I'm gonna do a quick fire of maybe a few, then you tell me yay or nay, and why the yay, right?
- JKDr. Jessica Knurick
Okay.
- TNTrevor Noah
So salt. Is it a yay or nay?
- JKDr. Jessica Knurick
You need salt. Your body needs salt to survive. It's too much salt that's the problem, which is probably gonna be the, my answer to all of these.
- TNTrevor Noah
So now there's a battle between Himalayan salt or just normal salt. Which one is good? Which one is bad?
- JKDr. Jessica Knurick
They're, they're both fine.
- TNTrevor Noah
Marketing.
- JKDr. Jessica Knurick
Yeah.
- TNTrevor Noah
Sugar, good or bad?
- JKDr. Jessica Knurick
Again, sugar, I mean, there's sugar in fruit, and fruit is a wonderful food, right? So, um, th- because you're also getting all of those nutrients. And so sugar is not necessarily bad. It's the overconsumption of sugar that's bad. And particularly, like, added sugar like a soda, right? 'Cause you're just c- drinking s- sugar with no nutrients-
- TNTrevor Noah
Mm-hmm
- JKDr. Jessica Knurick
... at all. So, so that's kinda what you wanna stay away from or limit, um, versus just thinking sugar itself is bad.
- TNTrevor Noah
White sugar or brown sugar, which one is the best?
- JKDr. Jessica Knurick
They're the same.
- 1:05 – 1:35
The Brown Sugar Trap: Is It Actually Healthier?
- TNTrevor Noah
Oh, I always thought brown sugar was way healthier. I thought it was like brown rice. I would eat it all the time, and I'd be like, "Mom, look, I'm being healthy."
- JKDr. Jessica Knurick
No.
- TNTrevor Noah
And then she'd throw carrots at my head.
- JKDr. Jessica Knurick
[laughs]
- TNTrevor Noah
[upbeat music] This is What Now? with Trevor Noah. [upbeat music] Dr. Jessica... Wait, you know what's funny? We were all
- 1:35 – 3:35
Meeting Dr. Jessica Nurik: PhD in Nutrition Science
- TNTrevor Noah
debating how to say the name. I thought it was Knurick, and then someone else was like Nurick.
- EUEugene
Nurick. Nurick.
- TNTrevor Noah
Nurick.
- EUEugene
Nurick. Nurick.
- JKDr. Jessica Knurick
It's more-
- TNTrevor Noah
Which one is it?
- JKDr. Jessica Knurick
It's closer to the second one.
- TNTrevor Noah
It's-
- JKDr. Jessica Knurick
It's Nu- Nurick.
- EUEugene
Nurick.
- TNTrevor Noah
It is Nurick.
- JKDr. Jessica Knurick
Yeah.
- TNTrevor Noah
Huh.
- JKDr. Jessica Knurick
The K is silent like knife.
- TNTrevor Noah
I don't like silent letters.
- JKDr. Jessica Knurick
Yeah. [laughs]
- TNTrevor Noah
I'm not gonna lie. I'm just gonna put it out there.
- JKDr. Jessica Knurick
Yeah, it's-
- TNTrevor Noah
I'm not, I'm... Your name can be your name. I just don't think this is cool for people because it's like your name is like a trap.
- JKDr. Jessica Knurick
I, it's a made-up name.
- TNTrevor Noah
Imagine if I was like, "I'm Trevor Noah," and then they're like, "N-O- no, K-N-O-A-H."
- JKDr. Jessica Knurick
I mean, the H-
- TNTrevor Noah
T
- JKDr. Jessica Knurick
... is kinda silent, isn't it?
- TNTrevor Noah
Yeah. The Noah?
- JKDr. Jessica Knurick
Noah.
- TNTrevor Noah
You caught me. [laughs]
- JKDr. Jessica Knurick
[laughs] You have a silent letter too.
- TNTrevor Noah
I do. I do.
- JKDr. Jessica Knurick
Yeah.
- 3:35 – 4:37
Lifestyle vs. Hereditary: Can You Prevent Chronic Disease?
- TNTrevor Noah
help us break down the difference between lifestyle chronic diseases versus what is, like, a non-lifestyle chronic disease.
- JKDr. Jessica Knurick
Yeah, I mean, cr- uh, lifestyle related are just things that we know, we have pretty good evidence that, like, lifestyle related habits, um, or, or behaviors are actually impacting your disease risk.
- TNTrevor Noah
Okay.
- JKDr. Jessica Knurick
So there are some, like, chronic diseases that, that we don't necessarily know that. We don't know, like, how much behavior is, or, or, or, like, lifestyle is actually impacting it. Um-
- TNTrevor Noah
Like, is there an ex... Give me an example just so I can wrap my head around it. I'm trying to... 'Cause y- you said type 2 diabetes would be more lifestyle.
- JKDr. Jessica Knurick
Yeah.
- TNTrevor Noah
Okay. And then type 1, I guess no.
- JKDr. Jessica Knurick
Type 1, no. Yeah.
- TNTrevor Noah
Okay. So that's just, it might just be you, hereditary.
- JKDr. Jessica Knurick
Yeah, like an autoimmune type, type of response.
- TNTrevor Noah
Ah, okay.
- JKDr. Jessica Knurick
Yeah.
- TNTrevor Noah
Okay.
- JKDr. Jessica Knurick
Yeah. M- a lot of hereditary factors.
- TNTrevor Noah
Right.
- JKDr. Jessica Knurick
Yeah, a lot of genetics.
- TNTrevor Noah
Yeah. And so you, you're the s-
- JKDr. Jessica Knurick
Potentially other, like, e- environmental factors. We just don't know as well.
- TNTrevor Noah
So some we know for certain, or there's a lot of research to suggest it?
- JKDr. Jessica Knurick
Yeah. And it's also that, like, you could potentially prevent the chronic disease-
- TNTrevor Noah
Got it
- JKDr. Jessica Knurick
... with lifestyle change.
- 4:37 – 6:18
The Good Side of Social Media: Bridging the Expertise Gap
- TNTrevor Noah
Got it.
- JKDr. Jessica Knurick
Yeah.
- TNTrevor Noah
I love the world that you're in. Um, you know, when we, we were chatting to the team. I, I feel like you are one of the bright spots of social media.
- JKDr. Jessica Knurick
Hmm.
- TNTrevor Noah
You know? And Eugene and I were chatting about this the other day, and we were saying, like, it was... I'm, I'm not gonna take credit for it, 'cause you said it.
- EUEugene
Yo. 'Cause Jessica-
- JKDr. Jessica Knurick
[laughs]
- EUEugene
... things that happen in our friendships with taking credit.
- TNTrevor Noah
[laughs] I'm not gonna-
- EUEugene
These disclaimers need to happen more often.
- TNTrevor Noah
I'm not gonna take credit because-
- EUEugene
So buckle up
- TNTrevor Noah
... because you said it.
- EUEugene
[laughs]
- TNTrevor Noah
But Eugene said something very valuable. He said, "You know, w- we can always jump to try and, like, vilify social media, and we can look at the bad, and we can..." You know what I mean?
- EUEugene
Hmm.
- TNTrevor Noah
But we also forget that there's a good side of what's happening on social media. There's also a good side of what happens on TV, et cetera. And I was like, "Man, Eugene, I f- I feel you, man. I feel you."
- JKDr. Jessica Knurick
Yeah. Class half fu- full.
- TNTrevor Noah
And, yeah. Yeah. And I, I feel like you're one of those bright spots, an expert on social media breaking down the most complicated-
- EUEugene
Yeah
- TNTrevor Noah
... topics for everyone to fully understand.
- JKDr. Jessica Knurick
Thank you. I appreciate that.
- TNTrevor Noah
No, we thank you. No, genuinely.
- EUEugene
Hmm.
- JKDr. Jessica Knurick
Yeah.
- TNTrevor Noah
We do. I love how you got into it as well. You know what I mean? It's like one minute you're, you're the scientist who's, like, really working on, like, the, uh... What do they call it again? The, um, uh, you, you, you write the research papers and the-
- JKDr. Jessica Knurick
Like a grant?
- EUEugene
The sketch pad?
- TNTrevor Noah
No. You're not my friend.
- EUEugene
[laughs]
- 6:18 – 9:34
Why Academics Avoid Social Media (and Why That’s Changing)
- JKDr. Jessica Knurick
Yeah, I've kind of, um, I've kind of talked about this before, that, um, for a very long time it was ver- really frowned upon for academics to go on social media.
- TNTrevor Noah
Right. Hmm.
- JKDr. Jessica Knurick
So it was ki- uh, it was looked down upon. I, I first went to social media actually back in 2016. My little brother was like, "You should get on this new app." It was like, um, Twitter's, like, version of a video app. And so I, I was teaching nutrition courses at, at a university at the time, and I was like, "You know, I could teach on, on this app. I'll just like, whatever my lesson is that day, I'll go teach it on the app." So that's what I did, and I, like, built up this little following within a few months, and, um, I got a lot of pushback from colleagues and from former colleagues.
- TNTrevor Noah
Hmm.
- JKDr. Jessica Knurick
And, you know, I was a brand new tenure track professor, and I didn't wanna, like, put my career in jeopardy.
- TNTrevor Noah
Yeah, yeah.
- JKDr. Jessica Knurick
And so when that happened and, you know, people were making fun of me, like, "How's your vlog doing?"
- TNTrevor Noah
Oh, damn.
- JKDr. Jessica Knurick
Um, and, and that was a really common occurrence. It was just not a space that, like, we were supposed to be in. And so I got off, and I was off for years and years after that. And I, I've talked to lots of other, like, academics and even, like, medical doctors, and they all feel very similarly. Like, it just, it was really frowned upon for us to go to social media, and unfortunately, that's where people go, for better or worse, for their information. And so we lost a lot of ground for many years-
- TNTrevor Noah
Hmm
- JKDr. Jessica Knurick
... not going to spaces where people went for information. Um, and so that's what really initially, well, well, I guess the second time, brought me to social media, was I was pregnant with my son. No, I was pregnant with my son in 2019 and then my daughter in 2022, and between those times, for whatever reason, I think it was after COVID, it was also, like, Twit- uh, TikTok had come out.
- TNTrevor Noah
Mm-hmm, mm-hmm.
- JKDr. Jessica Knurick
And I just started seeing way more misinformation than I had seen the first time around, and, like, getting targeted it, with it in my algorithm. Um, and so that's, I was like, "Well, that's not correct." And, like, I felt kind of a obligation to protect that particular demographic 'cause, like, we're quite vulnerable at that life stage when we have young kids-
- TNTrevor Noah
Hmm
- JKDr. Jessica Knurick
... um, or we're pregnant. And so I just went on and started correcting kind of, like, nutrition misinformation in the pregnancy space. Um, and then, you know, my, my content has shifted much more so, um, in the last year or so after last summer when I saw a lot of, you know, this, like, movement happening, uh, in public health and nutrition. It just happened to be, like, my exact area of focus the last 15 years. And so I was able to really see the manipulation that was happening with the narrative.
- TNTrevor Noah
Hmm.
- JKDr. Jessica Knurick
And, um, I decided to just start correcting some of the misinformation, and so that's kind of, like, what brought me to, to here, where I am now, sitting with you, Trevor. [laughs]
- TNTrevor Noah
Do you guys need a moment? [laughs] I've got places to be today.
- JKDr. Jessica Knurick
Here we are. Serendipitous. [laughs]
- TNTrevor Noah
[laughs] I, I, we always have this debate about social media, and we're thinking there's a pushback in trying to find... Not even a pushback, maybe a U-turn in how we experience social media now. People are trying to look for the bad, but seems like you found the good. What is, what is the good that is in social media right now that people can go look for?
- JKDr. Jessica Knurick
Well, I think that there's a lot of good content out there.
- TNTrevor Noah
Hmm.
- JKDr. Jessica Knurick
You just have to, like, sort through it and sift through it, right?
- TNTrevor Noah
Hmm.
- JKDr. Jessica Knurick
So, like, sifting through the bad. But I mean, it, social media gives you the opportunity to learn from people you never really would've been able to learn from before, right?
- TNTrevor Noah
Yeah, access.
- JKDr. Jessica Knurick
Like, if I have, like, a question about some sort of, like, beauty product, there's, like, so many dermatologists out there or cosmetic chemists just, like, creating content about it. And I'm like, "This is wonderful." So I think that's a great part about it. If you can find people giving credible information, I think it can be a great source of information.
- 9:34 – 12:01
How to Spot a "Health Scam" Online: 3 Major Red Flags
- TNTrevor Noah
Hmm. How do you figure out who the credible person is, though? Yeah.
- JKDr. Jessica Knurick
You know-
- TNTrevor Noah
That, that's, like, the biggest obstacle for me, is, you know, when I, when, when my friend sent me your videos at first, I was like, "This is amazing." Yeah. And then the, the second thing I always have to tell myself is I go, like, "Is it amazing because I want to believe it?" Mm-hmm. Because I'm not an expert. Mm-hmm. So how do I know this is the right thing? Hmm. And that becomes, like, the ultimate paradigm, uh, paradox, rather, online, is you get it from an expert, so you think it's real, and then you go, "Wait, how do I know this person is an expert?" 'Cause everyone's a doctor, you know? The Dr. Oz doctor. Yeah. And then if Dr. Oz says it-
- JKDr. Jessica Knurick
Everyone's a doctor. [laughs]
- TNTrevor Noah
Yeah, no, do you know what I mean?
- JKDr. Jessica Knurick
Yeah.
- TNTrevor Noah
Like, people just doctor. Everyone doctor, doctor, doctor. Hmm. Like, how did you... W- Was there a moment when people were like, "Who are you to say this?" I, I'm sure people even say that to you now in some way. I'm sure there's some people who go like, "You're the scam. You're the fake person."
- JKDr. Jessica Knurick
Yeah, people are always gonna do that, right? But-
- TNTrevor Noah
Did you just say that?
- JKDr. Jessica Knurick
[laughs]
- TNTrevor Noah
What do you mean? Is, is this how you feel? No, I'm... That's not how I feel. I said the... I'm sure- There's so much conviction in your eyes. Yeah, because I channeled the comments section. Okay, maybe let me ask Jessica the question.
- JKDr. Jessica Knurick
I just had that look on my face.
- TNTrevor Noah
Okay, okay, you ask the question. Dr. Jessica, do you find that sometimes on social media people look at you and think p- perhaps maybe you're the scam?
- JKDr. Jessica Knurick
[laughs]
- TNTrevor Noah
That was actually-
- JKDr. Jessica Knurick
Was that better?
- TNTrevor Noah
That was actually better.
- JKDr. Jessica Knurick
Yeah.
- TNTrevor Noah
That was better.
- JKDr. Jessica Knurick
I, I think that yes. I think that if, um, you know, if, if I'm saying something that, like, somebody doesn't like, it's very easy to write somebody off, just, just saying, like, "You're a scam," or whatever it is. Um, I think there's a couple of things you can look for. This is not foolproof, but, like, some things to, like, identify if somebody is giving accurate information. Um, they, they tend to not be super sensational.
- TNTrevor Noah
Hmm.
- JKDr. Jessica Knurick
So, which plays really well into the algorithm, right? So a lot of times-
- TNTrevor Noah
Mm-hmm
- JKDr. Jessica Knurick
... in my space, if it's, like, nutrition misinformation, they'll scare you at the front of the video, right? They'll scare you about, like, if you're poisoning your children or if you're consuming toxins.
- TNTrevor Noah
Oh.
- JKDr. Jessica Knurick
Um, experts don't generally talk like that. Like, ge- genuine people who are trying to educate are not gonna scare you. They're gonna explain the nuance. So if there's some sort of inflammatory claim at the front, that's kind of a red flag. And then particularly then if they walk you through kind of why, why it's, why that's so toxic or whatever it is, and then try to sell you something at the very end. Generally, those are some, like, good red flags. I'm not saying that's al- always the case.
- TNTrevor Noah
Mm-hmm.
- JKDr. Jessica Knurick
Um, but that's just something to, like, keep in mind. Maybe this is not, maybe this information, you know, has an ulterior motive to try to get me to purchase their whatever it is at the end. Um, so I think kind of being aware of that, and then, um, again, really sensationalized information is generally not how, like, experts talk.
- 12:01 – 13:51
The MAHA Movement: Identifying Real Problems vs. Fake Cures
- TNTrevor Noah
That, that feels like the crux-
- JKDr. Jessica Knurick
Hmm
- TNTrevor Noah
... of the RFK Me- uh, MAHA movement, Make America Healthy Again.
- JKDr. Jessica Knurick
Mm-hmm.
- TNTrevor Noah
Which, by the way, is a great starting point. Mm-hmm. Who doesn't want America to be healthy?
- JKDr. Jessica Knurick
No one.
- TNTrevor Noah
Yeah, you know what I'm saying? Well...
- JKDr. Jessica Knurick
Well, some people, but-
- TNTrevor Noah
Yeah. [laughs] Well, eh. You know what I mean? [laughs] But it's like, yeah, who doesn't want America to be healthy? Yeah. And then they go like, "Hey, you know, the, the foods that we're giving our kids and the-" One of the things I noticed about, you know, somebody like RFK and, and the people around him is they're often really good at identifying real problems.
- JKDr. Jessica Knurick
Yeah.
- EUEugene
Mm.
- TNTrevor Noah
They're not lying about the problems. And so they rope you in by saying, "Hey, kids are unhealthy, and kids are not getting good food in schools. And, you know, the, the medi- the pharmaceutical industry might not have your best..." And everyone's like, "Yeah, yeah, yeah, yeah." And then to your point, it flips, and then they sell you something.
- JKDr. Jessica Knurick
Yeah, I mean, it's great because, you know, the, the... If you identify a correct problem that, like, we all care about, and then you see somebody kind of countering some of the, uh, like, misinformation that's being spread, it's very easy for those people to be like, "Why don't you want America to be healthy?" People ask me that sometimes.
- TNTrevor Noah
Yeah.
- JKDr. Jessica Knurick
And it's like, "Wait, no, I want America [laughs] to be healthy. That's why I'm talking about this." Um, but I think it's, like, a brilliant kind of, like, propaganda tool to do.
- TNTrevor Noah
It's, it's, it's the snake oil salesman handbook. That's what it is. You come in, you identify the problem, and then you go, "I immediately can cure this thing with my snake oil."
- EUEugene
Yeah.
- JKDr. Jessica Knurick
Yeah.
- EUEugene
But I also feel like with nutrition, it gets very tricky sometimes. You know, growing up, there were those ads that would be like, "Open your cupboard right now, your food pantry. Open your fridge right now."
- TNTrevor Noah
Yeah, yeah.
- EUEugene
"Everything in there that you see is wrong." Then they'll be like, "Fresh veg- fruits and vegetables, you must eat this and eat that." But now later on in life, you get to hear, "So much sugar in fruit, so much sugar in this, so much sugar in that."
- JKDr. Jessica Knurick
Yeah, actually-
- EUEugene
"Don't eat, don't drink fruit juice. It's not good for you." It feels like the messages have been confused.
- TNTrevor Noah
What... Yeah, what, wait, what... Let's-
- EUEugene
Yeah
- TNTrevor Noah
... let's...
- 13:51 – 15:45
The Truth About Fruit: Fiber, Sugar, and Metabolic Impact
- TNTrevor Noah
Actually, what is the truth around that?
- EUEugene
Mm.
- TNTrevor Noah
Fruit good, fruit bad?
- JKDr. Jessica Knurick
Fruit good.
- TNTrevor Noah
Oh, okay.
- EUEugene
Fruit juice?
- JKDr. Jessica Knurick
Yeah. [laughs] Well, fruit juice is different than fruit, 'cause fruit itself has a lot of fiber in it. Um, fruit juice kind of strips out the fiber.
- EUEugene
Mm.
- JKDr. Jessica Knurick
So fruit juice essentially has a lot of sugar and not a lot of the fiber that f- that real fruit has. And so there c- those are differences in terms of, like, their metabolic impact on you.
- EUEugene
Mm-hmm.
- JKDr. Jessica Knurick
So we don't have a problem eating too much fruit in this country. Like, there's, we actually, m- most of us, almost 90% of us don't meet fruit intake guidelines. So the benefits of eating fruit, which is, like, all of the micronutrients and polyphenols and antioxidants and all of that, and the fiber, um, far outweigh any problems that we would see with, like, the, the sugar, 'cause the sugar's packaged within the fruit. So it's different than just k- like drinking a soda, for example, which doesn't have any of that. It's just the sugar.
- TNTrevor Noah
I, I can eat half a watermelon-
- EUEugene
Yeah
- TNTrevor Noah
... in one sitting.
- EUEugene
Same.
- JKDr. Jessica Knurick
That's a lot. [laughs]
- EUEugene
Same.
- TNTrevor Noah
Okay.
- JKDr. Jessica Knurick
Does that give you GI issues?
- EUEugene
Yeah.
- JKDr. Jessica Knurick
[laughs]
- EUEugene
Do you feel itchy somewhere? 'Cause that's GI.
- TNTrevor Noah
I don't think, I don't think that's GI.
- EUEugene
Oh.
- TNTrevor Noah
I'm glad we've got an expert here.
- JKDr. Jessica Knurick
[laughs]
- TNTrevor Noah
I don't think GI has-
- JKDr. Jessica Knurick
GI is, like, gastrointestinal.
- TNTrevor Noah
[laughs]
- JKDr. Jessica Knurick
Yeah.
- 15:45 – 18:02
The Surprising History & Stereotypes of Watermelon
- TNTrevor Noah
Yes, watermelon.
- EUEugene
Oh, I love watermelon.
- TNTrevor Noah
I mean, how can you not love watermelon?
- EUEugene
Yeah.
- TNTrevor Noah
You know the greatest scam ever committed?
- EUEugene
Is eating it shirtless.
- TNTrevor Noah
No.
- EUEugene
Oh.
- TNTrevor Noah
But I'm, I'm into it.
- EUEugene
You must try it.
- TNTrevor Noah
I've never thought of that.
- EUEugene
Spot's gone.
- TNTrevor Noah
Wow.
- EUEugene
Just you, a sticky chest.
- TNTrevor Noah
Damn.
- EUEugene
Then shower straight after.
- TNTrevor Noah
No, what I was gonna say is, like-
- EUEugene
Then finish off the rest of the watermelon that's left
- TNTrevor Noah
... what I was gonna say was, like, the craziest thing, the worst thing that ever happened was, like, when I came to America, and then I discovered, like, here, watermelon had, like, racist connotations. Then I was like-
- EUEugene
Oh.
- JKDr. Jessica Knurick
Oh, yeah
- TNTrevor Noah
... "What?" And they were like, "Oh, Black people love watermelon." And I was like, "Yeah." And they're like, "You love it." And I was like, "Yeah." [laughs]
- EUEugene
What is that?
- TNTrevor Noah
And they were like, "No, but you love it."
- EUEugene
Yes, yes, yes.
- TNTrevor Noah
I was like, "Yeah."
- EUEugene
Where does that come from?
- TNTrevor Noah
Ah, man, it's all, like-
- EUEugene
Jessica, do you know? Are you a nutritionist?
- JKDr. Jessica Knurick
I don't know. I, I... [laughs] I don't.
- 18:02 – 19:40
Food Deserts: Why Fresh Produce is Hard to Find
- EUEugene
I always feel like in any industry, there's always corporations getting involved and trying to take people off eating fruit and vegetables that are fresh, and going for the packaged foods. Do you find that in urban areas and in cities and in first world countries mostly, fresh fruit and vegetable are very expensive and unattainable for most people?
- JKDr. Jessica Knurick
Yeah, they're certainly more expensive relative to, uh, when we're looking at, like, the caloric density, so how many calories are-
- TNTrevor Noah
Yes
- JKDr. Jessica Knurick
... actually in the food. They're certainly more expensive than, than these packaged foods. A lot of that is because of the policies that we've enacted in this country. Um, and- Particularly kind of like zoning laws that have created these, what we term food deserts in a lot of the urban areas, um, where they literally don't have access, like easy access-
- TNTrevor Noah
Mm-hmm
- JKDr. Jessica Knurick
... to a grocery store with fresh fruits and vegetables. So, so they're going to dollar stores and they're going to gas stations for a lot of their groceries. Um, and so you know what we might take for granted, going to a grocery store, like I live in the suburbs, there's like five grocery stores within a, a close proximity.
- TNTrevor Noah
Yeah.
- EUEugene
Hmm.
- JKDr. Jessica Knurick
A lot of people don't have that, and so they have to take like, you know, multiple buses to get to a grocery store.
- TNTrevor Noah
Mm.
- JKDr. Jessica Knurick
And then they don't h- have transportation, so they're carrying all of that home, and it just, the, the barriers of access are much higher. So it's not even just cost, it's also just accessibility-
- EUEugene
Mm
- JKDr. Jessica Knurick
... of fresh fruits and vegetables. Um, and so what that, what happens then is people are heavily reliant on prepackaged foods, uh, much more so, so they're e- they're more accessible, they have longer shelf lives.
- EUEugene
Yes.
- JKDr. Jessica Knurick
The same fruits and vegetables go bad after a few days, and if you don't, you know, prepare them, um, then you have to go back and do that whole thing again to try to get a- access to them. Um, so yeah, that, that is a big problem in our country. I mean, millions of Americans live in these food deserts, um, that, that don't have r- easy access to fresh fruits and vegetables.
- EUEugene
Wow.

Defining Ultra-Processed Foods (The NOVA Classification)
- TNTrevor Noah
do, how do we think of ultra-processed foods? Because depending on where you look, they'll tell you they give you cancer.
- EUEugene
Mm-hmm.
- TNTrevor Noah
Uh, they causing obesity, you shouldn't eat any of them. Some people are like, "Oh, it's in moderation." Some people are like-
- EUEugene
Hmm
- TNTrevor Noah
... "No, they're, they're completely fine." W- w- what's your view on ultra-processed foods? And I know that's a broad term, but maybe-
- JKDr. Jessica Knurick
Yeah, we should define it.
- TNTrevor Noah
Yeah, let's, let's define it.
- JKDr. Jessica Knurick
So there's not a, there's not a great definition for it, which is why HHS right now has k- kind of an RFI out to fi- like a request for information to-
- TNTrevor Noah
Okay
- JKDr. Jessica Knurick
... figure out like what is a good definition for ultra-processed foods, 'cause they do a lot of talking about ultra-processed foods, but we don't have a great definition. In the nutrition science research, we use something called the NOVA classification.
- TNTrevor Noah
NOVA classification.
- JKDr. Jessica Knurick
Yeah. So it's, uh, it's out of Brazil actually. And so they did like a first effort years ago to define what ultra-processed means, and they defined it as, um, foods that include an ingredient or a processing method that you don't have access to.
- TNTrevor Noah
Hmm.
- JKDr. Jessica Knurick
So you can't replicate it in your kitchen. So, uh, my, the best way I can explain it is with corn. So unprocessed would be corn you pick from the garden.
- TNTrevor Noah
Okay.
- JKDr. Jessica Knurick
Um, minimally processed would be like frozen corn.
- TNTrevor Noah
Okay.
- JKDr. Jessica Knurick
Um, so they just shuck the corn and put it in the freezer.
- TNTrevor Noah
Yeah.
- JKDr. Jessica Knurick
And then, um, processed would be canned corn.
- TNTrevor Noah
Okay.
- JKDr. Jessica Knurick
That they add a little sodium. So just adding sodium is considered processed, like-
- TNTrevor Noah
Yeah
- JKDr. Jessica Knurick
... in this classification. Um, and then ultra-processed would be a Dorito chip. So you can't-
- TNTrevor Noah
Wow
- JKDr. Jessica Knurick
... replicate a Dorito chip in your-
- EUEugene
You're good
- JKDr. Jessica Knurick
... kitchen. But there is corn.
- TNTrevor Noah
She's,
- 21:03 – 23:07
Are All Processed Foods Bad? The Nuance of Nutrient Density
- TNTrevor Noah
she's amazing.
- EUEugene
You are-
- JKDr. Jessica Knurick
[laughs]
- TNTrevor Noah
You see now?
- EUEugene
... good.
- JKDr. Jessica Knurick
So, but if we use that definition-
- EUEugene
Mm-hmm
- JKDr. Jessica Knurick
... right? Because the, well, again, the definition is an ingredient or processing method you don't have access to.
- EUEugene
Mm.
- JKDr. Jessica Knurick
So that really means any of these additives that, you know, uh, that, that we use to like preserve food-
- TNTrevor Noah
Yeah, yeah
- JKDr. Jessica Knurick
... or change the color of food-
- EUEugene
Hmm
- JKDr. Jessica Knurick
... or those types of things. Um, there is so much variability in the nutrient density of those foods. So you can have something like a Dorito chip that doesn't have very much nutrient density, right? It's not, it's not great for you. But then you can also have something like a protein powder would be considered ultra-processed, but you're getting a lot of protein in that protein powder.
- EUEugene
Ah.
- JKDr. Jessica Knurick
Right? So, so the problem-
- TNTrevor Noah
So you can't just go good or bad.
- JKDr. Jessica Knurick
Exactly. And, and, e- uh, the people in charge right now are wanting to go good or bad and, and kind of like demonizing the previous administration for not like taking a hard stance on ultra-processed foods.
- EUEugene
Hmm.
- JKDr. Jessica Knurick
But this is the reason. When you look at the science, there is, there's like nutrient dense ultra-processed foods, and th- they're more accessible. And so if someone can devise a healthful diet that includes a lot of ultra-processed foods, but that it can still be a health promoting diet for those people who don't have access to fresh fruits and vegetables, for example, then we can't demonize those foods, right? The, the, we have to identify that, oh, those can actually be health promoting. Um, and so there's, there, we still need to do a lot more research in this area, and they, they, you know, um, they've been doing some of that research at the NIH looking at ultra-processed foods. Um, so it's very, it's a very nuanced kind of like ecosystem there. Um, but, but at the end of the day, low nutrient ultra-processed foods, these prepackaged foods, um, there's pretty good evidence that they're, that they're negatively impacting our health.
- TNTrevor Noah
How do, how do we figure this out? I- i- is there like a, a simple trick that we can use when we're out there buying food? You know, uh, so let's use Doritos as an example.
- JKDr. Jessica Knurick
Yeah.
- TNTrevor Noah
Someone grabs a bag of Doritos.
- EUEugene
I did.
- TNTrevor Noah
Uh, I wasn't gonna say who. Someone grabs a bag of Doritos, right? They haven't eaten that morning.
- JKDr. Jessica Knurick
Yeah.
- EUEugene
I didn't.
- TNTrevor Noah
I wasn't gonna name any names. And then they start nibbling away, and you can see that this person is hungry, and there's-
- EUEugene
I am
- TNTrevor Noah
... yeah, and they're just like, "You know, I just need like a few little nibbles of a thing, nibbles of a thing," and then they eat it. And then afterwards, they
- 23:07 – 26:51
The Science of Satiety: Why You Can’t Stop Eating Chips
- TNTrevor Noah
still don't really feel like they've eaten anything.
- EUEugene
I don't.
- TNTrevor Noah
And their stomach isn't full.
- EUEugene
At all.
- TNTrevor Noah
And they're going, "I still need to eat something."
- EUEugene
After the podcast, yeah.
- TNTrevor Noah
And because I feel like I need to eat something, it means that that wasn't like necessarily bad for me or didn't... Do, do, do you get what I'm saying?
- JKDr. Jessica Knurick
Mm-hmm. Mm-hmm.
- TNTrevor Noah
How do, like what, what is that gap that we, that we're... 'Cause we, we all experience it. Someone goes like, "Oh, I still have space."
- EUEugene
Mm.
- JKDr. Jessica Knurick
Mm-hmm.
- TNTrevor Noah
So help me understand that, 'cause I, I, on a, on a, you know, if I just read it, uh, ultra dense calories, I'm like, "Yeah, I understand this." I don't really understand it.
- JKDr. Jessica Knurick
Okay. So-
- TNTrevor Noah
Hmm
- JKDr. Jessica Knurick
... with Dorito chips, let's take Doritos.
- TNTrevor Noah
Yeah.
- JKDr. Jessica Knurick
I mean, I don't mean to throw Doritos under the bus, but-
- TNTrevor Noah
No, no, no. Let's say all chips.
- JKDr. Jessica Knurick
Yeah.
- TNTrevor Noah
All the chips.
- JKDr. Jessica Knurick
Chips.
- TNTrevor Noah
Yes.
- JKDr. Jessica Knurick
Let's, let's look at chips.
- TNTrevor Noah
Yes.
- JKDr. Jessica Knurick
So chips tend to be high in salt and fat.
- TNTrevor Noah
Okay.
- JKDr. Jessica Knurick
And so any combination of salt, sugar, and fat are g- is gonna be what we term hyper-satiating, right? So it's gonna be like you-
- EUEugene
Unholy trinity
- JKDr. Jessica Knurick
... you can just keep eating it, right?
- EUEugene
Mm-hmm.
- 26:51 – 28:41
Hunger vs. Fullness: How Hormones Signal Your Brain
- TNTrevor Noah
[laughs]
- EUEugene
You know, everything that you are saying about Doritos is so true about how they make you feel, 'cause I'm constantly battling with that. If I haven't eaten anything healthy in the morning, I'll start with junk and I'll start thinking I'm, I'm doing good, but then I'll feel even worse throughout the day. But my question has always been: What is, what is the definition of being full, and what is the definition of being hungry? Because there's people who go, "I don't eat that much," and they're fine, but there's people who if they skip a meal, they ultimately, you know, they fall into collapse because they are super hungry. So when you're eating something good, what is the battery level of, "No, now I'm full"? Is it because you've had the mass of food, or is it because-
- TNTrevor Noah
Oh, yeah
- EUEugene
... your mind is going, "We've ticked that box. We've got enough of that, and we're good now"?
- JKDr. Jessica Knurick
I actually do not know the exact answer to your question.
- EUEugene
Mm.
- JKDr. Jessica Knurick
Whether which one it is. I just know, we ha- we obviously have hormones that are kind of, like, sending signals to our brain. We have hunger hormones, we have... And satiety hormones. And so essentially-
- EUEugene
What are s- satiety hormones?
- JKDr. Jessica Knurick
Satiety means-
- EUEugene
Satiety
- JKDr. Jessica Knurick
... like you're full. Like-
- EUEugene
Okay
- JKDr. Jessica Knurick
... so hunger and then full.
- EUEugene
Okay.
- JKDr. Jessica Knurick
Um, and so when, you know, when you are eating to a certain level, this is why they kind of say to, like, eat slow and digest your food because it gives, like, it gives your hormones essentially time to kind of trigger your brain, "Hey, we're full," right? So if you're kind of, if you are relaxed, you're sitting. You know, a lot of people on vacation say that they feel a lot better when they're on vacation when they, when they're eating, and a big part of that is they're relaxed. They're not stressed. They're not running around while eating, and, like, they're not driving their car and eating a sandwich, right? They're, like, sitting at a table and chatting and, like, having a meal and digesting that meal. And so when they do that, they tend to eat less as well-
- EUEugene
Mm
- JKDr. Jessica Knurick
... because when you're digesting, it gives those signals time to be like, "Hey, we're full, so let's not overeat."
- EUEugene
Mm-hmm.
- JKDr. Jessica Knurick
Which is another thing about ultra-processed foods. It makes it really f- like, convenient to eat quickly, right? And so the quicker we eat, the more we're gonna eat before we feel that feeling of full.
- 28:41 – 32:25
Calorie Density Explained: Watermelon vs. Doritos
- TNTrevor Noah
Okay, so help me understand one more thing. Uh, 'cause I, I, I, I, I really don't get this even though I try and read it and understand it.
- EUEugene
Mm.
- TNTrevor Noah
How is it that that tiny bag can make you gain weight when it's, like, that, that tiny? Help me understand, like, the calorie and, and-
- JKDr. Jessica Knurick
Mm
- TNTrevor Noah
... why you're gaining weight from a thing. So I, I can eat half a watermelon, as I've said.
- EUEugene
Mm.
- TNTrevor Noah
And I can eat, like, a few bags of Doritos. Now, I'm not saying this scientifically.
- EUEugene
Yeah.
- TNTrevor Noah
But the Doritos will... If I look at my body, if I have, like, if I have a week of terrible food like that-
- EUEugene
Mm-hmm
- TNTrevor Noah
... I'll see a difference versus if I eat, like, watermelons the whole week type, like, fruit things. W- how, how does that work? Because it, it seems like this is, the mass of this is greater.
- EUEugene
Mm-hmm.
- TNTrevor Noah
But I don't think people fully understand how that tiny amount of food is making them gain more weight than more food, like, in a plate.
- JKDr. Jessica Knurick
It's just calories. It's, 'cause what, it's what we term energy density or calorie density.
- TNTrevor Noah
Yeah.
- JKDr. Jessica Knurick
So a, a watermelon is very, um, is not calorie dense at all, which means that for the mass that you're consuming-
- TNTrevor Noah
Okay
- JKDr. Jessica Knurick
... the calories are very low, right? Because they're, the watermelon, first of all, it has tons of water. Like, that's its main thing. Um, it's also got fiber, and it's got all of these other, like, properties to it. So, so when you're consuming it, you, it feels like you're eating a lot. It's just like if you consume, like, a huge plate of vegetables, right?
- TNTrevor Noah
Yeah. Mm-hmm.
- JKDr. Jessica Knurick
There's not gonna be a lot of calories in those vegetables, but it's gonna look like a lot. Like, uh, you're gonna... If you hand me a big salad, I'm gonna be like, "Whoa, that looks big." And then you hand me, like, this little bowl of pasta. It might not look as big, but it's gonna have way more-
- TNTrevor Noah
Ah
- JKDr. Jessica Knurick
... calories in it-
- TNTrevor Noah
Okay
- JKDr. Jessica Knurick
... than my big salad-
- TNTrevor Noah
Okay
- JKDr. Jessica Knurick
... right, of, of vegetables, you know, w- if you don't put dressing on it. So it's, it's all about the caloric intake.
- TNTrevor Noah
Yes.
- JKDr. Jessica Knurick
So the, the small bag of chips has likely far more calories than the half a watermelon or th- the few pieces of watermelon, whatever you're eating of the watermelon.
- TNTrevor Noah
Right. Yeah, yeah, yeah. Right.
- JKDr. Jessica Knurick
Um, so, so, so that's really what you're looking at.
- 32:25 – 34:36
Macronutrients 101: Why You Need Carbs and Fats
- TNTrevor Noah
is, this is what people need to learn. I, I-
- EUEugene
Yeah?
- JKDr. Jessica Knurick
Yeah
- TNTrevor Noah
... genuinely... Yeah, okay.
- JKDr. Jessica Knurick
So there's, what, we have macronutrients and micronutrients.
- TNTrevor Noah
Okay.
- JKDr. Jessica Knurick
Micronutrients are vitamins and minerals, right?
- TNTrevor Noah
Got it.
- JKDr. Jessica Knurick
Vitamin C, vitamin D, whatever it is. Macronutrients are calorie-containing nutrients.
- TNTrevor Noah
Mm.
- JKDr. Jessica Knurick
So that's protein, carbohydrates, and fat. Those are the, those are the three, like-
- TNTrevor Noah
Got it
- JKDr. Jessica Knurick
... prot- So, so everything you eat is comprised of i- and/or protein, carbohydrates-
- TNTrevor Noah
Got it
- JKDr. Jessica Knurick
... fats.
- TNTrevor Noah
Got it.
- EUEugene
And, and two out of those three-
- JKDr. Jessica Knurick
And those all have calories
- EUEugene
... okay. Two out of those three have been demonized.
- JKDr. Jessica Knurick
Except with-
- EUEugene
Carbs and fat.
- JKDr. Jessica Knurick
And we-
- TNTrevor Noah
Yes.
- JKDr. Jessica Knurick
Yeah, and we need all of them. They're all very important.
- TNTrevor Noah
Okay.
- JKDr. Jessica Knurick
Yeah, they all play roles in our, in our physiology.
- TNTrevor Noah
So if you were advising somebody on their diets and they said, "I'm staying away from carbohydrates-
- JKDr. Jessica Knurick
Uh-huh
- TNTrevor Noah
... and fats," you would be not happy?
- JKDr. Jessica Knurick
No, because you cannot eat 100% protein diet.
- 34:36 – 35:55
The Problem with "Meat-Only" Carnivore Diets
- TNTrevor Noah
When we, when we look at food labels, how are we able to discern any of this ourselves? So, you know, I know there's that, like, simple rule that they give you where they say, "If you wanna stay healthy, stay on the outside of a grocery store."
- JKDr. Jessica Knurick
Yeah.
- EUEugene
Wow.
- TNTrevor Noah
And they go like, "Just never go in."
- EUEugene
Mm-hmm.
- TNTrevor Noah
"So stay on the perimeter-
- EUEugene
Mm-hmm
- TNTrevor Noah
... and then leave."
- EUEugene
Mm-hmm.
- TNTrevor Noah
"And they say you will be healthier."
- EUEugene
Mm-hmm.
- TNTrevor Noah
Right? But, but if people are looking at a package, how do you know when the thing is or isn't bad? Because I, I remember once seeing, um, um, RFK was talking about, like, ingredients in food, and he was like, and he was like, "Oh, look at the back label." And I had to read the subtitles. [laughs]
- EUEugene
[laughs] I was, I was like, "Sticky Lizard, is that you?"
- TNTrevor Noah
No, and he would... And then he was, like, talking about the thing. And he said like, "Uh, this is, what is this? What is this? What?" And, and then-
- EUEugene
Mm
- TNTrevor Noah
... there was scientists who came on and said, "No, that's just the scientific name for vitamin C."
- JKDr. Jessica Knurick
No, it was riboflavin, I think, in that video.
- TNTrevor Noah
Yeah.
- JKDr. Jessica Knurick
Yeah.
- TNTrevor Noah
And it was like, "Oh, no, that's just the scientific name for s- for salt."
- JKDr. Jessica Knurick
Mm-hmm.
- TNTrevor Noah
"And that's the scientific..." So-
- EUEugene
Mm
- TNTrevor Noah
... like, h- is, is there a shortcut, or is there a way to know what, like, the colloquial word is versus the scientific word? Or, like, how, how, how are people supposed to know this? 'Cause it all seems like it's poison-
- EUEugene
Yeah
- TNTrevor Noah
... when you read it on a bag, but then some of it is not.
- JKDr. Jessica Knurick
Yeah.
- TNTrevor Noah
And then some of it may be.
- 35:55 – 39:50
How to Read a Nutrition Label Without Getting Overwhelmed
- JKDr. Jessica Knurick
So w- when you're looking at a nutrition label... And this is why, um, like, I'm a big advocate of front-of-package labeling, which is, like, more clear for people to really understand, oh, this is high in sugar, or this is high in fat.
- TNTrevor Noah
Yeah.
- JKDr. Jessica Knurick
Just so people are more aware. Right now, we don't have that, but they're working on it. But, um, we have labels, and you'll always be able to see the amount of calories, the amount of protein and carbohydrates and fats, um, and then an ingredient list.
- TNTrevor Noah
Right.
- JKDr. Jessica Knurick
And so, you know, it depends on what someone's goal is really. Like, if you're looking at a label... I don't actually look at labels much myself.
- TNTrevor Noah
Oh.
- JKDr. Jessica Knurick
Um, because I kind of, you know, I, I, I don't eat a t- ton of, like, prepackaged food, but the pa- prepackaged food I eat, you know, if I'm buying, like, crackers or something, you can look at it if you want to and, like, look at how much fat a cracker has, and then you can compare it to another cracker that has a bit lower fat. Um, but, you know, if, if you are just kind of, like, shopping for yourself, um- I don't, the label, the label can give you, you know, s- the way that the ingredients label is, is that it's, the first ingredient is the largest in the, in the food.
- TNTrevor Noah
Okay.
- JKDr. Jessica Knurick
And then it, it goes down from there. And so a lot of times in the ingredient list it's, like, vitamins and minerals, and there's a lot of them.
- TNTrevor Noah
Yeah.
- JKDr. Jessica Knurick
Especially, like, wheat products, 'cause we, um, fortify our wheat here, and so they have, like, different B vitamins in them. Um, so a lot of times it can s- feel very overwhelming to see, like, a big, long ingredient list.
- TNTrevor Noah
[sighs]
- JKDr. Jessica Knurick
But it's not as overwhelming as one might think.
- TNTrevor Noah
That's interesting.
- JKDr. Jessica Knurick
Yeah.
- TNTrevor Noah
Because it's actually just contained in the food, 'cause that's how the food was made.
- JKDr. Jessica Knurick
Yeah.
- TNTrevor Noah
Like, the, the, the actual...
- JKDr. Jessica Knurick
Mm-hmm.
- TNTrevor Noah
Yeah, you see, I didn't know that about wheat in that way.
- JKDr. Jessica Knurick
We fortify and we fortify with, like, vitamins, um-
- TNTrevor Noah
Right, right, right
- JKDr. Jessica Knurick
... and minerals in the, in the wheat.
- EUEugene
So you'd find that people who work out will have a pre-workout meal and a post-workout meal sometimes. Maybe it's a shake, maybe it's a salad, whatever it is. The average person who doesn't work out, do you have to be conscious about if you're gonna have maybe a busy day and you're gonna work, you're gonna walk, like, maybe four miles today, can you specifically look into your ca- pantry or your fridge and go, "I'm gonna eat like this because I'm gonna be active," versus, "I know I'm not gonna get out the house for the next four days, so eating this might be bad for me."
- JKDr. Jessica Knurick
In terms of the amount that they're eating?
- EUEugene
In terms of the kind of food and the amount that they're eating.
- JKDr. Jessica Knurick
Uh, they're, so they're going for a walk for f-
- EUEugene
Yeah, let's say I know that-
- JKDr. Jessica Knurick
A four-mile walk?
- EUEugene
... this week I'm gonna, I'm gonna walk.
- 39:50 – 45:16
The Psychology of Eating: Postpartum Anxiety & Food Fear
- TNTrevor Noah
interesting that you said that. Do you think there needs to be an overlap in how we talk about these subjects?
- JKDr. Jessica Knurick
Mm.
- TNTrevor Noah
Because for a long time, experts have always, like, stayed in their lane.
- JKDr. Jessica Knurick
Yeah.
- TNTrevor Noah
And I mean, like, just stayed in their lane.
- JKDr. Jessica Knurick
Yeah.
- TNTrevor Noah
You know?
- JKDr. Jessica Knurick
Mm-hmm.
- TNTrevor Noah
They'll go like, "No, no, I'm a bone doctor." And you're like, "But are you a doctor though?" They're like, "Yes, of bones." You're like, "But can you tell me what's..." They're like, "No."
- JKDr. Jessica Knurick
Mm.
- TNTrevor Noah
"Bones."
- JKDr. Jessica Knurick
Mm-hmm.
- TNTrevor Noah
And I'm not saying they shouldn't do that, but it, it almost feels like w- then the gaps open up for the people who are like, "Oh, I can tell you about bones and more."
- JKDr. Jessica Knurick
Yeah.
- TNTrevor Noah
And those people may not be the experts, you know? Uh, like I've, I've seen a bunch of your videos where, for instance, you're talking to moms. And I understand why, because you told us the personal connection you have with misinformation online to moms. But I've, I've noticed that you, you get into the emotional side of things. You don't just say, "Here's the facts."
- JKDr. Jessica Knurick
Mm.
- TNTrevor Noah
"Here are the..." Yeah. You'll say, like, "I know you're scared," or, "Hey, it might be scary when you hear," or, "When you... You might be worried about that," or-
- JKDr. Jessica Knurick
Mm
- TNTrevor Noah
... "Here's..." You feel like you want to... When did, when did you decide, or why do you think it's important to, to make that shift and expand beyond, like, just the literature and the science and include the human on the other side of the information?
- JKDr. Jessica Knurick
I think I benefit from my audience and the, the conversations that I have, like, in my DMs, which I, which I actually do engage with quite often, and, and hearing how much stress and anxiety and, and food anxiety-
- TNTrevor Noah
Mm
- JKDr. Jessica Knurick
... um, many of these women have. And, and again, I went through this life stage of pregnancy and postpartum, and I actually, with my second I had pretty bad postpartum anxiety. And so, um, I, it was important to, it's, I mean, I, I kind of lived it. And so I understand how they are feeling.
- TNTrevor Noah
Yeah.
- JKDr. Jessica Knurick
And I think that that gives me a lot of empathy for what's, what they're, what they're f- going through. Um, and so that's actually why I also am, like, so committed to kind of correcting some of this misinformation, particularly-
- TNTrevor Noah
Yeah
- JKDr. Jessica Knurick
... that that's targeted at new moms and young moms.
- TNTrevor Noah
Right.
- JKDr. Jessica Knurick
Because, because anxiety is really high. And so I hear from women all the time in my DMs about how much food anxiety they have and how they're scared to eat anything, and how-
- TNTrevor Noah
Oh, mm
- JKDr. Jessica Knurick
... you know, because that's, that's what the al- If you get into a particular algorithm on social media and you just keep seeing the same things over and over, and that's what plays really well to social media algorithms, are these conspiratorial kind of c- really sensational claims, um, it can be really problematic. And so I think it's really important to me when I'm presenting information to meet people where they are and, and kind of, like, bridge that gap so then they'll be more open to kind of hearing the information that I'm providing and, and the data that I'm providing.

time?
- TNTrevor Noah
Do the other people ever respond back to you? Like, w- because you're out there saying, "This is false. This is fake." Do those people ever come back at you?
- JKDr. Jessica Knurick
Um, I mean, it's happened a few times.
- TNTrevor Noah
Yeah?
- JKDr. Jessica Knurick
Usually they just block me.
- TNTrevor Noah
Oh, lazy.
- JKDr. Jessica Knurick
[laughs]
- TNTrevor Noah
So they don't, like, try and challenge you at all?
- JKDr. Jessica Knurick
Not usually, no.
- TNTrevor Noah
Ah, man. I, I always-
- JKDr. Jessica Knurick
Sometimes, though.
- TNTrevor Noah
Oh, yeah?
- JKDr. Jessica Knurick
Sometimes. Yeah, sometimes they refuse to, like, accept what I've said too, or they'll just kind of, like, dig in. Um, just depends on who it is, I suppose.
- TNTrevor Noah
So in that type of scenario, when someone is claiming to be an expert and another person is an expert- Is an expert, mm-hmm ... how do you then show a neutral observer where the truth actually lies?
- JKDr. Jessica Knurick
Yeah. Yeah, so I, um, I don't rely on them to just believe me because I'm me. I, that's, that's why I use so many, like, references in my videos, and I'll show, like... If I, if I tell y- For example, um, a lot of people on social media are saying, like, s- synthetic food dyes are banned in Europe.
- TNTrevor Noah
Yes.
- JKDr. Jessica Knurick
Right?
- TNTrevor Noah
Yeah.
- JKDr. Jessica Knurick
Like, you've probably heard it.
- TNTrevor Noah
Uh-huh.
- JKDr. Jessica Knurick
Red Dye 40 is banned in Europe.
- TNTrevor Noah
Mm-hmm.
- JKDr. Jessica Knurick
So I will... And I, I think that's a harmful narrative, because what it does is it kind of, like, plays into this idea that, like, America is poisoning us-
- TNTrevor Noah
Mm
- JKDr. Jessica Knurick
... and all these other countries care.
- TNTrevor Noah
Mm-hmm.
- JKDr. Jessica Knurick
Like, their scientists care, and their regulatory agencies care, and they're banning these things, and that's just not true. And so what I'll do is I'll show, you know, all five synthetic food dyes that are used in the United States predominantly, which is red f- uh, Red 40, Yellow 5, Yellow 6, Blue 1 and Blue 2, have all been deemed safe by EFSA in the European Union. All of them.
- TNTrevor Noah
Oh, they have?
- JKDr. Jessica Knurick
All of them.
- TNTrevor Noah
Huh.
- 49:44 – 55:38
Are Seed Oils Toxic? Sifting Through the Science
- JKDr. Jessica Knurick
that's the best kind of misinformation. You, you have a little bit of truth, and that's what gets people a- l- that's what brings people in.
- TNTrevor Noah
Yeah.
- JKDr. Jessica Knurick
Right? It's like, "Oh, they're- they're helping." Even if it's like 80% of the time they're helping.
- TNTrevor Noah
Yeah, yeah, yeah.
- JKDr. Jessica Knurick
Right? Some of these people. And it's like they're giving out good information, but it's the 20% of the time where they're completely manipulating the narrative and then, you know, taking advantage of you and the narrative, um, that's really the biggest problem. So yeah, I think, I think you're right, there is a problem right now because, um, much of the misinformation we see, which is sometimes why it's the h- so hard to kind of combat it and, and, like, explain the nuance because there's, there's overlap there.
- TNTrevor Noah
Mm.
- JKDr. Jessica Knurick
There's like, we, yes, this is true, and here is how that is being mani- manipulated.
- TNTrevor Noah
Yeah, because you now have, you have to go yes first.
- JKDr. Jessica Knurick
Yeah.
- TNTrevor Noah
And people are like, "Oh, so you do agree?" And then you're like, "But, but, but..." And now-
- EUEugene
Yeah
- TNTrevor Noah
... now it's too late. Like seed oils is a good one.
- EUEugene
Mm-hmm.
- TNTrevor Noah
That, that's like one of those myths that also doesn't go away. Do, do you, do, do you, do you ever see these where no matter what happens they just keep coming back, they just keep coming back, they just... So, like seed oils is a good one.
- JKDr. Jessica Knurick
Yeah.
- TNTrevor Noah
Um-
- EUEugene
Sunflower oil versus canola oil.
- TNTrevor Noah
It, just seed oils in South A-
- JKDr. Jessica Knurick
Those are both seed oils
- EUEugene
... in South Africa, that's what's going on now.
- TNTrevor Noah
Oh, that's the fight in South Africa?
- JKDr. Jessica Knurick
Oh.
- EUEugene
Yes, 'cause they're going, "Canola is, canola oil is used for things that you wouldn't wanna know about." And then people for a long time were using canola oil over sunflower oil.
- TNTrevor Noah
Huh.
- EUEugene
Yeah.
- TNTrevor Noah
And now the switch is people are going back to sunflower.
- EUEugene
Now everywhere you go, canola oil, canola oil, canola oil, canola, canola. So there's a big drive, I think it's a fight back obviously from the sunflower industry-
- JKDr. Jessica Knurick
Mm
- EUEugene
... that's going, "You need to use sunflower oil. You need to use sunflower oil." So a lot of people now have moved there. Avocado oil hasn't caught on that much, and obviously olive oil hasn't caught on that much, but the big battle right now in South Africa is between canola oil and olive oil.
- TNTrevor Noah
So are, are seed oils-

The Marketing of "Healthy": Organic, Non-GMO, and Protein Claims
- JKDr. Jessica Knurick
distinction.
- TNTrevor Noah
But I think to Eugene's point- A- and I mean, we've seen this. It, it's not even a conspiracy. We've seen how we are also, like you're fighting with, uh, you know, uh, misinformation.
- JKDr. Jessica Knurick
Mm-hmm.
- TNTrevor Noah
But we also forget that there's a company in the background somewhere, there's a food lobby somewhere that's trying to push something-
- JKDr. Jessica Knurick
Mm-hmm
- TNTrevor Noah
... to push something else out, to push something in. Like, look at how many years fat was bad.
- JKDr. Jessica Knurick
Mm-hmm.
- TNTrevor Noah
And then we found out, remember in that investigation where the, like the sugar lobby worked really well-
- JKDr. Jessica Knurick
Mm-hmm
- TNTrevor Noah
... to vilify fat and carbohydrates.
- JKDr. Jessica Knurick
Mm-hmm.
- TNTrevor Noah
And then only now are we going, "Oh, damn, sugar, you know." We didn't realize that sugar was, copious amounts of sugar. 'Cause again, nothing is just bad.
- JKDr. Jessica Knurick
Mm-hmm. Yeah.
- TNTrevor Noah
But sugar was the thing we should've been looking for in excessive amounts. But they, "It's fat-free."
- JKDr. Jessica Knurick
You're right.
- TNTrevor Noah
If it was fat-free, it was good for you.
- JKDr. Jessica Knurick
Mm-hmm, yeah.
- TNTrevor Noah
And you're like, "I can eat as much of it as I want 'cause it's fat-free, so I will not get fat." You know?
- JKDr. Jessica Knurick
Yeah. I mean, it's important. A- a- and I think you're, you're drawing an important distinction based on what, what are corporations going to do? First of all, the media is gonna sensationalize, like, science findings, right?
- TNTrevor Noah
Mm-hmm.
- JKDr. Jessica Knurick
A study, they're gonna sens- sensationalize the findings. But then corporations, they're gonna take any little thing and try to spin it as the, like, the best thing for them, right? So they're, and they'll use it in marketing. So if, you know, if there's a study that comes out that shows something good about blueberries, right, like, a product that has blueberries is gonna put that on their label-
- TNTrevor Noah
Yeah, they will
- JKDr. Jessica Knurick
... and be like, "This is the best thing that's ever happened," right?
- TNTrevor Noah
Mm-hmm.
- JKDr. Jessica Knurick
And so, so the problem is we need to be better at regulating those marketing claims. And, and so there are, there are s- quite a few claims that are regulated. Um, I think they just added, like, healthy last year. But there's quite a few that aren't, so they, they can put it on the label and just kind of like as a marketing tool for-
- TNTrevor Noah
Yeah
- JKDr. Jessica Knurick
... for the company.
- TNTrevor Noah
There's also a bun-
- JKDr. Jessica Knurick
You know, protein. Protein is that.
- TNTrevor Noah
Oh yeah, proteins having-
- 58:29 – 1:04:15
Why True Experts Aren't Afraid to Say "I Don't Know"
- TNTrevor Noah
understanding what a red flag is, is experts will tell you where their expertise ends. So you've said it, you know, we've had a, an, a, um, a neuroscientist on the podcast. We... And they'll go-
- JKDr. Jessica Knurick
Hmm
- TNTrevor Noah
... "Uh, actually, I don't know because that part I don't, I think this 'cause I know that part of it, but I don't know about this completely." And I wonder if that's also something-
- JKDr. Jessica Knurick
Yeah
- TNTrevor Noah
... we should look at as a, as a red flag-
- JKDr. Jessica Knurick
Red flag, mm-hmm
- TNTrevor Noah
... is if the person is all-knowing about everything all the time, something's fishy.
- JKDr. Jessica Knurick
Yeah, I think that is a good, good use of red flags on social media. Yeah, if somebody is, like, a- appearing to be a s- particularly, like, if they say they're a doctor and then they don't put their credentials in the actual, like, profile-
- TNTrevor Noah
Oh, yeah, okay
- JKDr. Jessica Knurick
... so they'll call themselves Dr. So-and-So, but there'll be no credentials, um, usually I have found that they are practicing outside of their scope of practice.
- TNTrevor Noah
Yeah.
- JKDr. Jessica Knurick
They're just... You know, you'll look at their page and they're an expert in nutrition and an expert in brain science and an expert in this and that. And so, um, that is a good thing to, I think, to look at.
- TNTrevor Noah
Yeah, like, I've always wondered, how does somebody who has, is just, let's say they're, they're a doctor of whatever, is, medical doctor or they've got a doctorate so they can say doctor.
- JKDr. Jessica Knurick
Hmm.
- TNTrevor Noah
How do they know about, like, 5G and Wi-Fi? I'm always, uh, 'cause I go, uh, aren't these two things separate?
- JKDr. Jessica Knurick
Hmm.
- TNTrevor Noah
And again, maybe I'm wrong, but I, I don't know that in medical school you're learning about r- the frequencies and radio waves and r- you, you, do you know what I mean? But I, but I, like, how do you deal with those types of claims? Do you, do you then pass it off to somebody? Do you, you know, like, what do you, what do you do with that when somebody says to you, um, "Oh, uh, Dr. Jessica, this is, this thing here is also, does this cause that?" What do you say to them in, in that instance? Do you go, "Well, I just don't know. Move on to someone else"? Or have you, like, formed, like, a little team of experts who you can pass it on to?
- JKDr. Jessica Knurick
I have, yeah. So if somebody asks me a question that's just outside my scope of practice, they, they do that quite often with, like, um, like, in, uh, beauty toxins.
- TNTrevor Noah
Okay, yeah, yeah.
- JKDr. Jessica Knurick
So, like, you know, the clean beauty movement.
- TNTrevor Noah
Yes.
- JKDr. Jessica Knurick
And that's just not my area. I, they ask me, like, "What about this ingredient in lotion?" I have absolutely no idea. So I have, like, cosmetic chemists that I'll refer people to.
- TNTrevor Noah
Oh, I love that.
- JKDr. Jessica Knurick
Yeah. So, so that, it's helpful to have, like, a little network of people who are outside your area.
- TNTrevor Noah
Oh.
- JKDr. Jessica Knurick
Yeah.
- TNTrevor Noah
Almost like a Avengers.
- JKDr. Jessica Knurick
Yeah. [laughs]
- EUEugene
Avengers of health.
- TNTrevor Noah
Yeah.
- 1:04:15 – 1:49:13
The Truth About Supplements: Essential Vitamins vs. Expensive Urine
- TNTrevor Noah
that you're giving it to people for free. You know? Th- this is something that we don't focus enough on in, in society-
- EUEugene
Yeah
- TNTrevor Noah
... and it's that you have to pay for the truth-
- EUEugene
Yeah
- TNTrevor Noah
... but lies are free.
- JKDr. Jessica Knurick
Hm.
- TNTrevor Noah
You know what I mean?
- JKDr. Jessica Knurick
Yeah.
- TNTrevor Noah
Like, there's no website that has lies that you have to pay for. Search anything online, search about any story, any news article, any health article, you name it.
- EUEugene
Mm.
- TNTrevor Noah
The arti- the news, the websites and the pages that are fake-
- EUEugene
Yeah
- TNTrevor Noah
... are free.
- JKDr. Jessica Knurick
You're right.
- EUEugene
Yeah.
- JKDr. Jessica Knurick
Yeah.
- TNTrevor Noah
And then when it's a real thing, they'll be like, "Would you like to pay for the truth?"
- JKDr. Jessica Knurick
Right.
- TNTrevor Noah
And I'm like, "Yeah, but if it's so important, why..." And don't get me wrong, I under-
- JKDr. Jessica Knurick
Like The New York Times and The Wall Street Journal. Yeah
- TNTrevor Noah
... exactly. And, and don't get me wrong, I understand that there are-
- JKDr. Jessica Knurick
And they have to pay their people.
- TNTrevor Noah
Yeah, they have to pay people, et cetera. But it is sad that we, we live in a world... And, and that's why I also appreciate that, because this is not your job, and yet you are giving people education that they wouldn't otherwise be able to access if they weren't in the institutions that you're in.
- EUEugene
Yeah.
- JKDr. Jessica Knurick
Yeah, yeah. I mean, y- you're, you're bringing up a point that's kind of, um... It- it's g- it's, like, nuanced because we have to also figure out a way to make it sustainable for people to do.
- TNTrevor Noah
Yeah, yeah.
- JKDr. Jessica Knurick
Like, like science communicators and things like that. And so, you know, we're, there still has to be conversation about how to do that. But yeah, I, I think that it's really important and, and that's why... I mean, I have a Substack that it, I never put things behind paywalls and that's why. Like, I want people to have access to, to the information, um, because I think that that's really important and we, they shouldn't... You know, we, you don't want to put things behind paywalls if you really want people to understand them. But I also understand the other side, that people have to make a living, you know?
- TNTrevor Noah
Yeah. I feel like in a perfect world-
- JKDr. Jessica Knurick
So it's like a nuance
- TNTrevor Noah
... that, that sort of be like a fund maybe or a-
