The Too Thin author explains that when we eat pasty non-human foods, this super-fine food will start to digest in the small intestine. The more course whole foods will be rough enough that it will make its way down to the colon quickly before it has time to digest.
This would make sense. Uncooked foods often will exit the body much quicker than cooked foods.
The author explains those PAINS we feel after eating: Acids in the small intestine attempting to digest the wrong foods and these same acids enter into our blood stream and we feel sick....all self-induced! Probably the greatest explaination I have ever read explaining HEART BURN!
RAW FOODS move too quickly to allow ourselves to poison us. Nature is very smart! You can't easily our smart Nature, she has a penalty for ever sin we commit.
