The epiphysis of 17-year-old children is not closed, so this age will continue to grow and develop, so they will still grow taller. Therefore, if 17-year-old children want to develop their height faster, first of all, they should participate in more outdoor activities, especially running and jumping activities to stimulate the epiphysis of the limbs, so that the epiphysis grows actively, thus promoting the increase of height; secondly, they can eat more foods with high calcium content, such as shrimp, soy products, dairy products, lean meat, seafood and fresh fruits and vegetables, to promote the absorption of calcium, thus promoting the development of height The second thing is to eat foods with high vitamin D content such as egg yolk, cod liver oil and animal liver to promote the absorption of vitamin D. This will promote the absorption and digestion of calcium and promote the development of height.
