Research is not the right place to seek answers to questions about health. Time does not permit me to list all of its problems, but at the top of the list is the fact that unless you investigate the methodology used in each study and know whom it was conducted by and for what reasons ($), you cannot trust the published outcomes. On top of that, medical research is not true science. It relies heavily on animal studies, which are fatally flawed. Even when the studies are done on humans, the researchers are biased going in. The germ theory and the notion that humans are omnivores are two examples of unproven ideas that researchers commonly labor under, and many times base their conclusions on. You must be aware of the mountain of contradictory and conflicting information that has come from medical science. The entire field is a vast morass of confusion. In the end, we all know that research is driven by money and nobody makes any money by proving that raw food is optimal.

I know it sounds like sacrilege, but we don't need studies. What we need to know, we can easily know without them. If this weren't the case, our ancestors would not have survived through the millenia. The truth is always obvious and self-evident, not hidden away in medical journals. If what you want is proof, eat all raw for 6 months. Then have a cooked meal, even one that you regard as "healthy" now. This will convince you better than any study could. If you're trying to convince someone other than yourself, you'll never be able to do it with medical research because a study that "proves" the opposite of what your study "proves" can always be found.
