Not JUST fruit. Raw fats lubricate, protect, and are an antioxidant. They are very nourishing. Our bodies instinctively crave raw fat. It must be realized to all true health seekers that raw fat is exactly the opposite of cooked fat.
Cooked fats are carcinogenic, loaded with free radicals, and are harmful in many other ways.
Read any cooked nutrition book and you readily discern the dangers of cooked and processed fats. However, realize that raw fats are of a totally different biochemistry than cooked fats. Experiment and find what works optimally for you. Fruit is the best and highest quality source of sugars, accompanied by various vitamins, minerals, enzymes, living water, and fiber. Don't fear sweet fruit, and don't buy into the suggestions by others to eat dead, devitalized, cooked starches.
