Puberty is a special stage of bone development. During this period, bones are very active in absorbing calcium and other nutrients, and these nutrients can keep bones strong and healthy throughout the rest of their lives. Therefore, eating foods rich in bone nutrients can help improve bone strength and its mineral content. This can strengthen their bones and reduce the risk of rickets and osteoporosis when they grow up. These skeletal nutrients include calcium, vitamin D, vitamin K, magnesium and zinc.
