Why “animal-based” shocks people: edible animals vs. defensive plants
Joe opens by describing the social backlash he gets for eating mostly meat, and introduces Saladino’s memorable claim: most plants are inedible while most animals are edible. They connect this to real-world examples like mushroom foraging mistakes and the risks of randomly eating vegetation.
- •Public fear that heavy meat intake is inherently dangerous (e.g., colon cancer claims)
- •“Animal-based” framing as a rebuttal to “plant-based” identity
- •Most wild plants are not safely edible; mushrooms as a high-risk example
- •Early setup for plants-as-defense-chemistry argument
- 2:09 – 4:43
Plants and animals as a 400-million-year arms race (and why we detox)
Saladino reframes diet through ecology: plants can’t run away, so they evolve chemical defenses. He argues human liver detox systems likely evolved to tolerate occasional plant intake rather than to optimize a plant-heavy diet.
- •Co-evolution and “warfare” between plants and animals
- •Plant defense chemicals (phytoalexins) as core botanical strategy
- •Phase I/II detox pathways as evolutionary tools for survival, not ideal nutrition
- •Questioning the default assumption that plants are benign or universally beneficial
- 4:43 – 9:17
Hormesis debate: sauna/exercise vs. plant ‘medicine’
Joe asks whether plant toxins can be beneficial via hormesis, similar to sauna or exercise. Saladino proposes two categories—environmental hormesis (heat, cold, exercise, fasting) and molecular hormesis (foreign compounds like plant chemicals)—and argues they shouldn’t be conflated.
- •Hormesis as adaptive stress: heat shock proteins, NRF2 activation
- •Environmental vs. molecular hormesis as distinct paradigms
- •Plants as ‘pharmacy’ without a package insert listing side effects
- •Claim that benefits attributed to plant compounds may be redundant with lifestyle stressors
- 9:17 – 15:06
Broccoli sprouts and sulforaphane: the ‘booby trap’ mechanism and thyroid effects
Saladino uses sulforaphane (from Brassica vegetables) to argue plant compounds trigger stress-response pathways while also carrying harmful effects. He explains sulforaphane’s formation only after chewing and links isothiocyanates to DNA damage signals and iodine/thyroid interference.
- •Sulforaphane formed only when chewing combines glucoraphanin + myrosinase
- •Pro-oxidant mechanism that triggers NRF2 but may have collateral effects
- •Isothiocyanates as goitrogens affecting iodine utilization and thyroid function
- •Argument: you can activate NRF2 via cold/heat/exercise without plant-toxin tradeoffs
- 15:06 – 22:09
Do fruits & vegetables improve biomarkers? Vitamin C, scurvy, and RCT skepticism
Joe presses on vitamins from plants, especially vitamin C and immune benefits. Saladino argues vitamin C needs may be lower than assumed, can come from animal foods, and notes many intervention trials fail to show strong benefits despite epidemiologic associations.
- •Claim: no essential nutrient uniquely requires plants; animal foods can supply equivalents
- •Vitamin C in organ meats and muscle; historical scurvy-prevention dosing data
- •RCT/meta-analysis discussion: weak effects on colds and major outcomes
- •Epidemiology vs. interventions as a recurring theme
- 22:09 – 31:34
Nose-to-tail eating: organs, indigenous priorities, and raw liver challenge
They pivot to ancestral eating patterns: indigenous cultures prize organs and fat, not just muscle meat. Joe and Saladino discuss wolves’ liver hierarchy, arctic explorer accounts, and then escalate into eating raw liver on-air, using it to illustrate nutrient density and cultural precedent.
- •Organ meats as historically prized and often distributed within tribes
- •Examples: wolves/alpha liver access; Stefansson accounts of favored fatty cuts
- •Raw liver tasting segment; “sacred liver” beliefs (Nuer tribe) and humor tangent
- •Food safety and nutrient-loss considerations between raw vs cooked
- 31:34 – 45:17
Foie gras ethics to regenerative agriculture: soil, subsidies, and scalability
A discussion about foie gras becomes a broader critique of factory farming and feedlots. They explore whether grass-fed/grass-finished and regenerative systems can scale, highlighting soil carbon improvements and how animals can restore depleted land—contrasting monocropping and subsidies.
- •Ethical inconsistency: banning foie gras while allowing factory farming
- •Grain-finished cattle still spend most of life on grass; consumer demand drives finishing
- •Regenerative examples: White Oak Pastures soil carbon vs neighboring monocrops
- •Policy/economics: corn/soy subsidies, Conservation Reserve Program, land restoration via grazing
- 45:17 – 53:28
Hunter-gatherer metabolism: fasting, ketosis cycling, and autophagy
They connect ancestral life to modern metabolic flexibility: intermittent fasting, switching between glucose and fat-burning, and the concept of cellular ‘housecleaning’ (autophagy). Saladino argues for cyclic ketosis rather than permanent ketosis, and Joe shares personal benefits from carnivore periods.
- •Metabolic flexibility: glycolysis vs beta-oxidation/ketones as ‘two engines’
- •Intermittent fasting and the mTOR/AMPK balance; autophagy explanation
- •Cyclic ketosis as a practical ancestral analog; carbs sometimes beneficial
- •Joe’s experience: stable energy, weight loss, perceived mental/behavioral shifts
- 53:28 – 1:10:39
Carbs on an animal-based diet: gluconeogenesis, fruit limits, honey + CGM data
Joe asks about gluconeogenesis and whether protein can kick someone out of ketosis; Saladino explains necessary glucose production from amino acids and glycerol. They then explore reintroducing carbs, using CGM readings to argue honey/fruit can be compatible, and discuss honey’s unusual dental and metabolic research.
- •Gluconeogenesis as essential backup glucose supply; protein can reduce ketosis depth
- •Saladino’s shift from strict carnivore to ‘carnivore-ish’ with honey/fruit for sleep/electrolytes
- •CGM observations: modest blood sugar changes with honey + animal foods
- •Honey research: oral applications, pH rebound, rat comparisons vs refined sugar
- 1:10:39 – 1:19:36
Plant toxicity spectrum and vegan ‘ideology’ dynamics (seeds, lectins, cyanide)
Saladino outlines a ‘plant toxicity spectrum’ based on which plant parts are defended (seeds, leaves) versus meant to be eaten (fruit). Joe and Saladino discuss seed toxins (amygdalin/cyanogenic glycosides), elderberry toxicity, and the social/ideological pressures within vegan communities.
- •Plants ‘want’ fruit eaten for dispersal; defend seeds/leaves with toxins
- •Examples: apple seeds, apricot kernels, almonds (toxicity bred out), elderberry raw toxicity
- •Veganism as lifestyle/identity: backlash toward defectors; anecdotal observations
- •EEG/behavioral claim: ‘motivational salience’ of animal foods persists
- 1:19:36 – 1:41:10
Processed seed oils as the modern driver: obesity/diabetes trends and linoleic acid theory
They pivot to the rise of chronic disease and track dietary trends, arguing vegetable/seed oils correlate most strongly with worsening metabolic health. Saladino focuses on linoleic acid, adipocyte changes, oxidation, and how monogastric animals (including humans) store dietary PUFA—linking feed practices to fatty acid profiles.
- •Chronic disease, obesity, and diabetes graphs rising despite less smoking and more exercise
- •Food trend comparison: red meat down, sugars down recently, vegetable oils up sharply
- •Linoleic acid hypothesis: signaling ‘winter is coming’ → fat storage/adipocyte hypertrophy
- •Ruminants vs monogastrics: PUFA storage in pigs/chickens/humans; feed changes fat composition
- 1:41:10 – 2:11:08
Cholesterol, LDL/HDL, and the ‘context’ model: metabolic health, oxidized LDL, and CAC=0
Saladino challenges the simplified ‘LDL bad, HDL good’ narrative, arguing LDL’s role as a nutrient/immune particle changes meaning depending on metabolic health. He critiques epidemiology, introduces HDL as a proxy for insulin sensitivity, discusses LDL oxidation (potentially from linoleic acid), cites PUFA intervention trials, and shares his own very high LDL with a zero coronary calcium score.
- •Standard lipid hypothesis vs. context: insulin resistance as the major driver
- •Framingham-style stratification: high HDL groups show minimal LDL-risk relationship
- •Oxidized vs native LDL; LDL quality and retention in subendothelial space
- •Interventional PUFA trials (Minnesota Coronary Experiment, Sydney Diet Heart) cited as negative
- •Personal labs: LDL >300 (reported 533) with low triglycerides and CAC score of 0; family history discussion
- 2:11:08 – 3:02:53
Carnivore transition realities: diarrhea, fiber myths, and Saladino’s raw-vegan cautionary tale
They close this segment with practical issues: the ‘disaster pants’ phase when switching to carnivore, a bile-acid explanation, and how small amounts of fiber can help during transition. Saladino disputes common fiber claims using an intervention study where zero fiber improved constipation, and he recounts his own period as a raw vegan with severe GI and muscle-mass downsides.
- •Diarrhea mechanism hypothesis: bile acids reaching colon during abrupt diet shift
- •Mitigation strategy: slower transition; temporary fiber (e.g., avocado) to bind bile acids
- •Fiber skepticism: cited 2012 study—zero fiber resolving idiopathic constipation in participants
- •Saladino’s raw vegan experience: extreme gas, muscle loss, and feeling unwell
