> This is another nail in the coffin for the scientific validity of paleo diets, which are based on the idea that human nutritional needs haven't changed since we were primarily hunter-gatherers. That is an inaccurate characterization of Paleo Diets. Typical modern diets being out of sync with human digestion is in no way incompatible with ongoing evolution. There is no evidence that human evolution will never make modern constructions such as transfats good for consumption. It doesn't make sense to derail discussions of dietary alternatives with brittle arguments about hunter-gatherer eating patterns that are not well understood.
