Raw veganism is medically called one of the worst diets, and it unfortunately draws unfair judgment on a more balanced vegan diet. That's in the West.
In Eastern medicine, eating all cold or raw foods can cause a physical imbalance, most notably digestive problems. You're supposed to balance hot and cold for example.
I think it's good to incorporate a lot of raw food into the diet, have fresh fruit, salads, nuts, seeds, sprouts, etc. Sure even have cold pressed juices. But it can easily tear up your digestive system, you may find it more difficult to absorb enough nutrients, and feel unsatisfied if this is all you eat for a significant period of time.
It's actually a fact that while over-cooking of foods can leech out certain nutrients, there are other foods that have more nutritional accessibility when cooked. We also developed cooking as a means of killing bacteria.
I have eaten at a raw food restaurant before, and it was really good but very expensive because it was gourmet concoctions.
Raw for breakfast and dinner sounds like it could be plausible, especially in warmer seasons or warm/temperate climates. I am guessing you'd see more raw foodists in southern California or Florida, or desert communities.
I'll have to look these individuals up. I have never considered a completely raw food diet as sane, though apparently it does work for certain individuals.
