Yogurt is made of milk, which can prevent osteoporosis, and it is converted into calcium lactate by lactic acid bacteria, which is more easily absorbed by human body. In addition, people who drink milk will have diarrhea. If they drink yogurt instead, they will not only get the same nutrition, but also will never have the problem of indigestion like drinking milk because lactose in milk has been converted into glucose by lactic acid bacteria. There are also benefits such as lowering blood cholesterol, improving immune function, and caring skin, all of which can be obtained by eating yogurt or yogurt products.
