A common misconception is that "Those who want to be healthy and slim should 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 German nutritionist and representative of holistic medicine, debunks the dogma about the benefits of low fat content in food, explains the role of fats in the formation of cells and organs in our body, and helps to understand which fats are really useful, and from which should be abandoned.
