You must have come across people who look younger or older than their age, especially in high school. Although this situation is not completely, it can usually change depending on when the person enters puberty. During this period of huge hormonal changes, our physical appearance also undergoes changes. So why do some people enter puberty early and some of us later?
The answer to this question was actually given by a research that investigated why people are getting taller. Researchers looking for the real reason behind the increase in people’s average height stated that such a discovery could lead to new drugs to improve muscle mass and treat delayed growth. The research was successful and explained why we hit puberty early and increase our average height.
It all depends on our gene and a receptor in our brain:
Until now, scientists were aware of the parallel relationship between nutritional health and puberty and height growth. The most concrete example of this was in South Korea. South Korea, formerly a poor country, has also improved its nutritional health after becoming a developing country. With the improvement of nutrition in South Korea, the average height of people has also increased significantly in a short time. But the bridge between nutrition and the resulting effects was unknown.
According to the research published in the journal Nature, scientists discovered that what causes this process is the receptor in the brain called MC3R. This receptor has been shown to act as a bridge between food and sex development and growth. The MC3R briefly tells our body, “Things are good here, we have a lot of food so grow up quickly. Be a teenager quick and make lots of babies. ” messages.
When the MC3R does not function properly, puberty is delayed and the person is short:
When this receiver, named MC3R, does not work normally, that is, it cannot send the right messages to our body, it is seen that people cannot grow in height. However, these people also enter puberty at a later age. The research team was able to prove this in the genes of half a million volunteers, which they obtained and screened from the UK biobank. Children found to have gene mutations that disrupt the receptor in the brain were shorter and lighter than other children.
