Lately there are many food intolerances and one of the many is lactose, a sugar naturally contained in milk and all its derivatives. The highest concentrations of lactose are found in milk, yogurt and fermented milks, ice creams, soft cheeses, cream and butter. However, it is also contained in many industrial products and baked goods in which milk is used. Even if it is traumatic, the first thing to do afterwards in the event of a positive test result is to give up pizza, buffalo mozzarella and cappuccino overnight, which is very hard but necessary. Eliminating all foods that are potentially harmful to the body is the first step to regain well-being.
