Is height determined by genetics?
Height is mostly genetic, and in some cases, it can even be skipped generationally inherited. If both parents are tall, the child is unlikely to be short, excluding some diseases acquired later in life. However, if both parents are short, the child can still promote their growth through certain exercises.
Under the premise of good nutrition, 70% of a child's height is determined by their parents' genetics. Parental genetics are the primary factor in determining a child's height, as 35% of the factors determining height come from the father and 35% from the mother. If both parents are short, then it will depend on the child's 30% of efforts through postnatal development. Generally, a child will inherit the height of the taller parent in the family, but postnatal life also has an impact on height.
1. Protein Intake: Protein is a crucial nutrient for children's growth. Japanese children have a habit of drinking a glass of milk every day, and their physical improvement has attracted worldwide attention: their average height has increased by 11 centimeters compared to their previous generation, and their weight has increased by 8 kilograms. Japan has become one of the countries with the longest life expectancy in the world and is internationally recognized as a "miracle in human physical development".
2. Physical Exercise: Physical exercise promotes blood circulation, accelerates metabolism, and promotes bone growth and development in children. Outdoor sports are also beneficial for calcium absorption. We often see children who enjoy running and are tan and strong rarely get sick and are sturdy and tall.
3. Psychological Pressure: Excessive psychological pressure on children can lead to disorders in the neuroendocrine system, affecting the secretion of growth hormones, ultimately resulting in stunted growth.
