Calcium is big news in nutrition.
The bottom line is that Americans should have three servings of non-fat milk or low fat dairy products each day. Milk provides three minerals known for their roles as regulators of blood pressure - calcium, potassium, and magnesium. Studies have shown that eighty percent of those who are lactose intolerent can drink a glass of milk without discomfort. Others may substitute yogurt or cheese to provide calcium. A glass of milk before bed will make you sleepy.
