The immunologist and bestselling author Attilio Speciani dispels the clichés about so-called 'food intolerances' and guides the reader to a healthy and better relationship with food. Colitis, migraines, hormonal changes, arthritis, autoimmune diseases, imbalances of metabolism and many other disorders, from the most common to the most severe, are often related to diet. There is a close relationship between food and health, and when the natural and physiological relationship with food changes, due to food excesses or the repeated introduction of food, the organism generates measurable inflammatory signals that induce and maintain many conditions or diseases.
