Milk is a very good source of calcium and promotes the health of bones. It is also a good source of riboflavin and B complex vitamins, especially B12, essential for cardiovascular health and the production of energy. Furthermore, milk is rich in vitamin A, which is necessary for good functioning of the immune system, and in potassium, which contributes to heart health. Compared to other animal products, milk is high in vitamin C that protects our body and at the same time facilitates the absorption of calcium at the gastrointestinal tract. Milk contains casein, a protein of high biological value. Casein contributes to the regulation of blood pressure, strengthens the immune system and alleviates stress. Finally, milk has linolenic acid, which seems to protect against the occurrence of various types of cancer, such as skin, colon and breast cancer.
