First, Mongolians are physically strong, which has something to do with diet. As we all know, the three nutrients that the human body needs are carbohydrate, protein and fat. What is the specialty of Mongolia? Dairy products and cattle and sheep. Dairy products and beef and mutton can supplement a lot of high-quality protein. In this diet structure, the more nutrients you supplement, the stronger your body will be, and there is a certain linear relationship between them.
Secondly, Mongolians are strong because they often exercise. A strong figure means more muscles in the body. If you eat a lot, but seldom exercise, then your meat is slack and fat. This figure can't be called strong, only fat. Only by eating more and exercising regularly can we have a good figure. Mongolia has a vast territory and is very suitable for riding. In addition, Mongolians are good at riding and shooting, wrestling and so on. These lifestyles will make their bodies look strong.
Third, Mongolians are strong in order to adapt to the bad weather environment. In winter in Mongolia, the temperature is very low, MINUS degrees Celsius. If you are weak, you can't resist the cold winter at all. Before there was air conditioning and heating, everyone had to rely on their own bodies to fight, except for making a fire with wood. Only by being strong can we spend the winter safely. Natural selection, survival of the fittest and long-term evolution have made the Mongolian body more and more adaptable to winter and stronger.
To sum up, the reason why Mongolians are strong is not only because of Mongolia's unique eating habits, but also because of the environment, living habits and so on. If you want to be strong, you can refer to the eating habits and lifestyle of Mongolians.
