As we age through childhood and into our teens, we frequently would hear people tell us that we looked much taller than when they had last seen us. We grow in height quickly, after all, the growing is (for the most part) done entirely in the first 18 years of our lives.
Genetics and your height
Children can get a general idea of their anticipated height when they grow up by simply looking at their parents. It is estimated 80% of an individual’s height is determined by DNA sequence variants they inherited (MedlinePlus).
In this way, how tall you grow is partially related to your genetics. However, which genes are affected and to what degree they have an impact on your height still needs to be better understood.
This makes the height of parents a good rule of thumb, but not an outright rule. You may know someone in your life who has a significantly different height than their parents.
The role of nutrition in influencing height
Vegetables and a healthy diet are essential in the development of young children. While loading up on vegetables will not automatically make you taller, it can help in ensuring you grow to your full potential height.
Your potential maximum height is, for the most part, set from birth in your genetics. You can not alter this to make yourself taller. Additionally, once you reach adulthood you will stop growing as well.
How exercise can influence height
Exercise, particularly early in life, can positively impact a child’s ability to achieve their maximum height later in life. This theory is based on the idea that increased exercise will result in stronger and larger bones.
Animals have been observed to have a correspondence between bone size and exercise.
However, what diet is eaten in correspondence with exercise can play a big role. Your body needs the energy from food to grow, but it also spends that energy exercising. Even with adequate exercise, a body low in protein can not develop as large of bones as intended.
