I'm interested in whatever nutritional profile produces the lowest long term disease risk. It doesn't seem like they fully know what that is, or if it's the same for everyone. They keep putting out studies saying plants are healthy, and I don't eat any meat, but occasionally you see people say their health improved on a carnivore diet, and nobody seems to know if it's a real effect or what is causing it, or what genetic factors might influence it. Everyone just talks a lot about bioavailable nutrients, but I would imagine that unless you're a bodybuilder, finding the optimal amount of each nutrient would be more interested than just trying to maximize everything, which is what some people seem to be doing. I'm kind of amazed that it's still not really fully clear what the healthiest way to eat is. Seems like most scientists are pretty well in favor of Mediterranean though, right?
