People have a tendency to believe that just because most people do something a certain way that it's the best way. In this culture, most people cook their food and have for a long time. It seems "unnatural" to eat food that has not been altered (by chemicals or by cooking). The fact is raw, living foods contain the enzymes, vitamins, minerals, carbs, proteins, fats and oxygen that the body needs in a form in which the body can use it. Once a food has been heated above approximately 118 degrees, the enzymes, vitamins and oxygen are cooked out. The minerals, carbs, proteins, fats are altered in such a way that the body cannot properly absorb the nutrients. It has also been shown that each time a person eats cooked food, the immune system kicks into high gear with increased white blood cell activity. So what's wrong with an active immune system? Well, when we keep it in high gear all of the time, it eventually gets tired and worn down. Then when there's a big threat, it has no strength left to protect the body.
More and more people are trying the raw food lifestyle and finding that they love the increased energy, and for many, the opportunity to live each day free of the symptoms of many troublesome "diseases". Even if you are not committed to going 100% raw, just increasing the amount of raw fruits, vegetables, sprouted grains, seeds and nuts can make a difference in the overall quality of life a person experiences.
