I don't know if fundamentalist is the word. I have no problem with killing animals for food or any other moral quandry. But it does make a lot of sense that we are NOT designed to eat cooked food.
The history is sketchy, but it's estimated that primitive cooking began between 8000BC and 6000BC. That's 10,000 years at most. Modern humans have been around for 100,000 to 200,000 years. The chance that our entire digestive system somehow evolved to be unlike any other digestive system in such a short time is very unlikely.
Bacteria being bad is also a myth. The problem is that we are so used to eating cooked food that we do not have the natural bacteria resistance we used to have. In fact, just by weaning yourself onto raw eggs and raw fish, you can avoid most bacterial infections when traveling aborad.
Nutriends definitely get damaged when you cook. Obviously there are varying degrees, but the important thing is that most enyzmes which aid digestion get destroyed between 118-145 degrees. Our bodies are designed to digest food with the aid of those enzymes.
You can eat certain beans by soaking them in water, although I don't know about soybeans or lentils. I do know that the Chinese ate soybeans before cooking was a common practice.
All that said, it's not NECESSARY, obviously, to eat this healthy. Your diet is probably better than 99.9% of Americans. However, I am quite sure based on my experience and that of others that Raw Food (including raw eggs and fish) is the best diet we know of.
