Maybe you will find that some people have white hair since childhood. This situation is also called "white hair". It is mainly common in young people and belongs to pathological white hair. Modern medical research generally believes that "baldness" is the cause of melanin production and pigmentation disorders in hair follicle cells, such as genetic factors, bad eating habits, tension and environmental pollution. But most people will have white hair later, which is related to age and dietary factors. For white hair that is not caused by genetic factors, we should pay more attention to our diet.

After forty years old, white hair gradually began to increase, mainly due to age factors. Some people have more white hair because of long-term mental stress, nutritional deficiency or illness. The appearance of white hair is related to melanin. The factors affecting melanin synthesis are related to tyrosinase activity, the number of pigment stem cells, the increase of free radicals in human body, the contents of trace elements copper and zinc, and the lack of genetic materials such as vitamins and chromosomes. Among them, the lack of tyrosine has an important relationship with white hair.

Tyrosine is an amino acid. If the intake of tyrosine in diet is insufficient, the synthesis of melanin will be seriously affected. Although black sesame is a black food, whether black sesame can nourish hair depends on the tyrosine content in black sesame. When it comes to the content of tyrosine in food, it belongs to soybeans and black beans. 100g The content of tyrosine in soybean or black bean is as high as 2g, which is much higher than that in black sesame.

Increase the intake of black beans or soybeans in your diet, and your hair will be darker and more shiny. As for whether black beans or soybeans can really make hair black, it depends on the transformation of tyrosine in human body. After all, black beans or soybeans are food, not medicine, and the process of dietotherapy is long, and you need to persist in order to be effective.

Copper in minerals is an essential element for hair to synthesize melanin. When the copper content in human body is lower than the normal level, it will not only cause metabolic disorder and anemia, but also make hair growth stagnate, fade and appear gray hair. In animal liver, lean meat, eggs, soybeans and hard fruits, besides copper, pantothenic acid is also rich, which can promote the formation of melanin and is also an important nutrient for blackening hair. If the diet is improved, the hair will become black and shiny, and the white hair will be improved.

In addition, according to the clinical observation of modern medicine, if the body lacks protein, vegetable oil, vitamin B 1, vitamin B2, vitamin B6 and other nutrients for a long time, it will also cause the hair to turn from black to white. Food is the main way for our body to obtain nutrition, and a reasonable diet is the basic condition for good health. If you are picky eaters or partial eclipse, it will lead to nutritional deficiency. China Residents' Dietary Guide and China Residents' Dietary Pagoda are the important basis for evaluating the dietary structure of China people and the important reference for improving the dietary structure. According to "China Residents' Dietary Pagoda" to match the diet, we can achieve a balanced diet and reduce white hair.
