raw foods: Try a Google on: raw vs cooked foods There are a ton of sites out there that should help you out! :-) Ed, RN|||Cooked foods are much easier to digest than raw foods. For example raw lettuce and raw broccoli are very hard to digest and give some people severe stomach cramps but cooked broccoli and broccoli soup is fine. The same applies to raw tomatoes and cooked tomatoes. Unfortunately during the cooking process some of the water soluble B and C vitamin content is lost so it is better to eat raw fruit and raw vegetables if they don't give you stomach or digestion problems.|||I will give you very simple "science". Raw foods (except meats.) lose NO NUTRITIVE value when eaten uncooked. All foods grown in the soil already have the proper enzymes to digest them and retain the highest food value. These enzymes are killed at a low temp--hence cooking kills most digestive enzymes that were originally in the food. Cooking foods has been necessary for many reasons mostly because not all people have a garden, so must cook and refrigerate their foods. There are ways to cook and still save most of the nutrients. The Highest way to throw away valuable nutrients is to boil, then throw away the water.|||the human body/system was designed to eat raw foods.cooking destroys all the enzymes and most of the nutrients making digestion difficult.you can find all the info on the net.
