Height is always a major concern for parents when it comes to their children’s growth. Many believe that a child’s height is entirely determined by parental genes, as if genetics were an insurmountable barrier. However, scientific research shows that genetics only account for 60-80% of height, while the remaining 20-40% depends on environmental factors, particularly nutrition, exercise habits, and sleep quality. During a child’s critical growth phase, a balanced diet not only supports physical development but also helps children break through genetic limitations to reach greater height potential. As parents, understanding how to support your child’s growth through diet is a vital step toward ensuring their healthy future.
