Two substances, tyrosine and tyrosinase, are necessary for melanin synthesis. There are two sources of tyrosine: one is taken from food and absorbed into the body through gastrointestinal digestion; the other is converted from certain amino acids in the body. Although tyrosinase is synthesized in the cells, its activity is in turn related to metal elements such as copper and zinc, which are also taken from various foods. Therefore, in daily life, we should pay attention to scientific dietary regimen, pay attention to the reasonable combination of various foods to ensure nutrition. The food will be disproportionate, nutrition deviation, resulting in the synthesis of melanin necessary substances relative lack, so the partial diet is not conducive to the treatment of vitiligo, we hope that this part of the patient as soon as possible to develop a good diet habits.
The reason is: 1, interfere with the normal eating routine of children, small food and beverage sweet and delicious, children will do it as a snack at any time to eat, long time can not according to time normal meal, disrupt the normal eating routine.

3, some do not meet the health standards of small food will contain many chemical additives, such as coloring agents, preservatives, sweeteners, etc. can cause direct harm to children’s bodies.
Researchers have found that some toxic substances, when absorbed, can also cause direct damage to melanocytes by inhibiting the activity of certain enzymes in the body and making melanocyte synthesis impaired. From the current incidence in various countries, it can be seen that the pollution of the environment and food has a greater relationship with the disease, with high population density and high incidence in developing countries, with India ranking first in the world, followed by China and Japan, with a lower incidence in Western developed countries. The incidence rate is significantly higher in China’s heavy industrial cities, oil-producing areas, and coastal areas.
