Raw Fresh Food vs. Cooked Food - Scientific Evidence
There are tons of studies that directly or indirectly point at the undeniable truth that a diet primarily of raw organics foods can cure or prevent disease. Here are just a few examples.
Scientific
evidence shows that raw vegan diets decrease toxic products in the
colon (From: J Nutr 1992 Apr;122(4):924-30). Shifting from a
conventional diet to an uncooked vegan diet reversibly alters fecal
hydrolytic activities in humans, according to researchers, Ling WH, and
Hanninen O, of the Department of Physiology, University of Kuopio,
Finland. Results suggest a raw food uncooked extreme vegan diet causes
a decrease in bacterial enzymes and certain toxic products that have
been implicated in colon cancer risk.
From the book Diet, Nutrition and Cancer
published by the Nutritional Research Council of the American Academy
of Sciences (1982) and the FDA (Food and Drug Administration) Office of
Toxicological Sciences, additional carcinogens in heated foods include:
Hydroperoxide, alkoxy, endoperoxides and epoxides from heated meat,
eggs, fish and pasteurized milk; Ally aldehyde (acrolein), butyric
acid, nitropyrene, nitrobenzene and nitrosamines from heated fats and
oils; Methyglyoxal and chlorogenic atractyosides in coffee; Indole,
skatole, nitropyrene, ptomatropine, ptomaines, leukomaines, ammonia,
hydrogen sulfide, cadaverine, muscarine, putecine, nervine, and
mercaptins in cheese.

Using words like "undeniable truth" in the context of science is palpable nonsense. Science is about the balance of evidence. While it will always be possible to find fringe scientific studies to support the most ludicrous of propositions this does not make it the "truth". There is plenty of other research that comes to very different conclusions.
