The first point is that pure milk contains high quality protein, which can promote the synthesis of a very important hormone called growth hormone in the process of growing taller after entering the body. The important raw material to promote growth hormone is protein, especially high-quality protein, so drinking pure milk can promote the synthesis of growth hormone through high-quality protein, which is still very beneficial to the growth of height. The second point is that pure milk is rich in calcium, which plays a good role in promoting the normal growth and development of bones. If growth hormone is sufficient, coupled with good bone growth and development, the positive effect on the growth of height is self-evident.
