I think its an interesting move from Pick up artist to Raw Food Fundamentalist. :)
But, I think raw food is another extreme end. Animals and us were probably not designed to eat cooked food. But over time we have evolved and our bodies have evolved towards it.
Now going back to HUMAN DESIGN. Humans have a digestive system like one that belongs to a cow. We were not designed to be meat eaters. So drop that meatloaf from your menu.
But we have evolved from being pure plant eaters to seafood and different meats.
Raw is good. Lots of raw is better. ALL RAW is probably not the best. RAW = Uncooked = Living Bacteria. Cooking kills common bacteria.
Now, talking about nutrient loss. Nutrients dont vaporize (maybe a little), but they are usually part of the original item and part of the liquid you cooked it in. Hence, dont BOIL and throw away the extra water.
Also LIGHT cooking is better than HEAVY cooking.
Once again, it is about BALANCE. Add a lot of raw foods: Salads, finger food carrots, fruits & nuts to your diet. But try eating SOYBEAN or LENTILS uncooked. You cant. Hence you boil the beans, lentils etc. and keep the liquid.
PS: This comes from a vegetarian who has grown up with half his lunch and dinner plate always consisting of sprouts salads, fruits, cucumbers, radishes, carrots & tomatoes.
