I just realized another massive foundational flaw in Generaux’s logic.
Generaux claims that the 1925 Wolbach and Howe study shows that the “Vitamin A Deficiency” was actually Vitamin A Toxicity, because Lard and Casein have more Vitamin A than claimed (and still do 100 years later), and that butter protects against Vitamin A toxicity, despite having much higher known levels of Vitamin A (hundreds of times more than the lard and casein together).
Yet, when Generaux constructs his own Vitamin A deficient diet, he takes all the Vitamin A levels straight from traditional databases like the USDA. Why? If you believe those values are wrong for lard and casein, why would you think they are accurate for things like beef and bison fat? Cattle graze on grass, and so are likely to get as much or more Vitamin A precursors than pigs. Why wouldn’t they store Vitamin A in their fat stores like pigs do?
Also, why not at least include butter in your Vitamin A deficient diet? I would think you could include any full fat dairy that hasn’t been fortified with Vitamins (and full fat usually isn’t). By Generaux’s own logic, it protected the rats in the Wolbach and Howe study from the “toxic vitamin A” in both butter AND casein, so isn’t it a massive oversight for anyone striving to protect themselves from Vitamin A toxicity to overlook this Vitamin A Toxicity Prevention Superfood?
