Fresh milk is a rich source of several essential nutrients, including protein, calcium, phosphorus, vitamin A and vitamin D. Reduced-fat fresh milk in particular, because it lacks the fat content of other dairy products such as whole milk, offers health benefits — yet fewer of the risks associated with consuming saturated fat and cholesterol. Including three servings of fresh milk in your diet each day can help you maintain muscle mass, strengthen your bones, support a favorable body composition and improve your circulatory health.
