The Improper Diet Can Cause Myopia For Children

People usually think that the myopia of children is caused by bad lines of sight, wrong sitting positions or some other factors. However, according to the latest research, the improper diet is also an important factor of causing myopia for children. In order to help children avoid getting myopia, it is essential to supplement some nutrients for them. Except protein and vitamins, calcium, chromium and hard foods are also necessary. The lack of calcium, chromium and hard foods can probably cause myopia.

Calcium is a kind of ordinary element for us. The main effect of it is to accelerate the growth of the bones and prevent rickets for children. Few people connect it with the health condition of eyes. According to the medical experts, the lack of calcium is an important factor of causing unhealthy development of eyesight and even myopia. The lack of calcium can cause the hydraulic pressure inside the eyeballs to be unstable, which can cause the abnormal growth of the eyes. Many foods contain abundant calcium, such as milk, bean products, fish, animal bones and so on. When people eat these foods, they can eat yolks, green vegetables and animal livers at the same time. These foods contain abundant vitamin D, which can improve the absorption and utilization of calcium for the human body.

Chromium is a kind of essential mineral element needed by the human body. It can maintain the balance of osmotic pressure. The imbalance of osmotic pressure can cause protrusion of crystalline lens and further cause myopia. According to the calculation of the experts, children need about 50 to 200 micrograms of chromium. In order to supplement chromium for children, mothers should provide corn, meat, cream and yolks for children every day.

In addition, mothers should provide some hard foods for children every day. Hard foods can increase the frequency and potency of eating and accelerate the development of eyesight for children. According to the medical research, the children who always eat soft foods like noodles are easy to get myopia, and the children who often eat some hard foods usually have normal eyesight. Chewing potency can increase the power of facial muscles including ocular muscles so as to make the muscles have the ability of adjusting crystalline lens. Suitable hard foods for children mainly include carrot, fruits, and bean products and so on. These foods all contain abundant nutrients for children to grow healthily.
