A common misconception reads: "Anyone who wants to be healthy and slim must give up fatty foods." In fact, everything turns out to be the opposite: the one who refuses fats in favor of carbohydrates becomes fat, unhappy and sick. Dr. Anne Fleck, a well-known nutritionist and representative of holistic medicine in Germany, debunks the dogma about the benefits of low fat in food, explains the role of fats in the formation of cells and organs of our body, and helps to understand which fats are really useful and which should be abandoned.
