But experts disagree. There was never consensus on this. I agree in general "trust experts" is way better than "do your own research" but nutrition science was never a consensus. Thimk for example of the current collapse of the alleged consensus on medicalization of youth gender distress. Other factors led to some research being ignored and other research pushed despite bad quality. Why do we integrate animal proteins so well and vegan protein so poorly? We co-evolved with our foods. Why is ruminant meat so otherwise nutritious and vegetables not particularly unless a variety that isnt easily found year round in a small geographic area? It would be weird if meat were bad for us and novel/modern foods better. Butter is better than margarine.
