Is it fine and ok for a teen(13-17) to drink 3 cups of full cream milk everyday?(the normal milk and not the skim milk)it is fine for our health and doesnt cause any health problem?(im asking it again bcz i didnt tell properly for earlier question).?

yes. If the person has no allergy to the milk and does not suffer from lactose intolerance this is fine. It should be integrated with other intake into a balanced diet.

Other sources of Vitamin D and Calcium include yogurt, cheese and certain vegetables. A healthy balanced diet is recommended. Regular milk is 4 percent fat and nonfat is zero. If non obese, it should be fine, otherwise skim may be advisable.
