The United States Department of Agriculture lists milk products such as yogurt as being highly beneficial in preventing high blood pressure and building strong bones and teeth. The potassium content found in yogurt helps keep blood pressure at a healthy level, and the calcium content provides the building blocks for proper bone mass and healthy teeth.
According to the Center for Young Women's Health in Boston, eating one cup of yogurt per day can contribute to preventing osteoporosis due to the calcium content and added vitamin D found in yogurt. This is especially true when you start a child on a healthy diet that includes yogurt.
