This is a surprising piece which goes against a lot of what I thought was established, namely that the carnivore diet of only meat was defective. Humans need anti-oxidants and other nutrients not found in meat, so the all meat diet is as flawed as the all-vegetable diet. But, consider the book by Paul Saladino, The Carnivore Code (2020):
“In his book, Saladino states he’s going to bust nutritional dogma, which he does in spades. Saladino, who struggled with asthma and eczema, was actually a vegetarian and then a vegan for a time. It didn’t help. In fact, it made things worse. His health problems didn’t resolve until he went on an exclusive carnivore diet, and he recounts the various twists and turns in his personal journey at the beginning of the interview. After hearing Jordan Peterson talk about the carnivore diet and how it improved his daughter's autoimmune symptoms, Saladino was intrigued enough to look into it. The rest, as they say, is history. “The more I thought about it and dug into it, I started to realize, maybe there's something to this,” he says. “I'm at least going to try it. And so, the first time I tried it, within a few days, my mood changed, and my outlook on life got to be significantly better and more positive. I thought, ‘There's something to this.’ A few weeks later, the eczema had completely resolved and hasn't come back since. I've been eating a carnivore diet for the last year and a half. But there really was this sort of personal quest throughout to find out what the triggering food was, and it was just so striking for me to see the eczema go away when I cut out all plants — and then the added benefit. The mental clarity, the psychological benefits were surprising. That kind of hooked me, and I thought, ‘OK. I need to just pour myself into this and understand this because this is going to help a lot of people, or it potentially could.’"
