1aoot3 | Does the body really treat cooked food as a toxin? | A friend of mine recently claimed that he watched a "peer reviewed" documentary called "Food Matters". In this documentary, they discussed how - in his words - that "cooked food is treated like a toxin by the body, which is why raw food is better". Is there any truth to this statement? I would simply like to know. | askscience | http://www.reddit.com/r/askscience/comments/1aoot3/does_the_body_really_treat_cooked_food_as_a_toxin/ | {
