If you are not aware at least 50% of your diet should be RAW. Raw foods are those, which have not been cooked, processed, pesticided, micro waved or genetically engineered. This belief is based on the notion that cooking food denatures the naturally present enzymes and nutrients in food. According to raw food experts, enzymes are the “life force of a food.” They help us to digest food and absorb nutrients. Enzymes are greatly connected to life, health and longevity. If you overcook and/or over consume all of the foods you eat, your body will not get the nutrition and enzymes it needs to thrive.
It really becomes about researching and understanding the best way to cook and eat your foods so that you receive the maximum about of nutritional value. For example, the cancer-fighting compounds in broccoli (sulforaphanes) are significantly reduced when broccoli is cooked. Vitamin C is also destroyed by heat. However, some foods become healthier after cooking. For example, cooked tomatoes contain more lycopene than raw tomatoes.
If you are committed to improving your health, then eating RAW is one step in the right direction. Remember: "Disease is found right at the end of your fork." :)
