It seems obvious that various animals have different natural diets, that is, different diets that they are evolutionarily adapted to. A horse eats grass, a cat eats meat. I expect that of you performed the same dietary experiments using horses as the experimental animal, you would get very different results than if you used cats as the experimental animal. Cats are obligate carnivores, and are on a ketogenic diet, always. Is the rat natural diet the same as the human? If so, this might have some relevance to the human diet. This appears to be another example of the garbage that passes for nutrition science.
