Is the hair “gray” old? The doctor says frankly: it is this kind of nutrition that you lack in your body

Nowadays, some young people like to dye their hair gray. The dark hair gives people a youthful and lively feeling, but now they dye their hair gray, which makes them mature. < / P > < p > they may not know that people’s hair will naturally “fade” with age. When people’s hair turns gray, it indicates that people are aging. But with the further study of hair by scientists, they found that the grayness of hair is not all caused by premature aging. In fact, the reason for the grayness of hair may be that you lack it in your body! Vitamin B12. < / P > < p > although the human body has little demand for vitamin B12, the lack of it in the body is also very worrying. When a person’s vitamin B12 is insufficient, his hair will gradually turn gray, and may eventually turn all white. < / P > < p > let’s look at this concept first. In fact, vitamin B is a big family with many members, including: VB1, VB2, VB3, VB5, VB6, vb7, vb9, VB12. It can be seen that vitamin B12 is only one of them. < / P > < p > but vitamin B group elements have one thing in common, that is, they are water-soluble cellulose, like vitamin C. Although the human body gets a lot of vitamin B from food for a while, after a period of time, they will eventually enter the urine and be discharged from the body with the metabolism in the body. There is only enough vitamin B left in the human body for later use, and the amount of vitamin B stored in the human body is very small. Therefore, the reason for the lack of vitamin B in the human body, to a large extent, is that the diet does not keep up. For example, people who lose weight excessively and those who do not eat fruits all the year round are prone to lack of vitamin B in the body. < / P > < p > health management believes that a person only needs to eat 30 grams of bovine liver every day to meet his demand for vitamin B12. Moreover, animal liver is rich in iron, which is the raw material for making blood and improves the oxygen carrying capacity of red blood cells. If there is enough blood and oxygen in the human body, the hair can be nourished and not easy to turn white. < p > < p > mutton is a high protein food, and also one of the foods with the highest content of vitamin B12. It can be used with green leafy vegetables and Lentinus edodes to supplement vitamin B elements. < / P > < p > however, to say more, although the method of dietotherapy is simple and feasible, some people’s hair turns gray early, which is due to congenital factors and can not be changed. It is “genetic”. If both parents have gray hair at an early age, the probability of their children’s “juvenile white” is higher than that of ordinary people. < / P > < p > there’s another reason why hair turns gray early, and that’s emotional stress. If young people are usually under great pressure, and then indulge in staying up late, smoking and drinking alcohol, they may eventually lose a lot of hair due to these bad habits. When the hair falls off, the hair follicles of the scalp continue to work and grow new hair. However, in the process of frequent hair growth, the “dye melanin” in the hair follicles gradually decreases, and finally becomes insufficient, unable to meet the requirements of dyeing black hair It turns grey. < / P > < p > to sum up, I hope you can find the reason why you grow gray hair. If it doesn’t appear for the time being, you might as well massage your scalp more and form the habit of combing your hair, which can promote blood circulation and prevent endocrine imbalance. Life as far as possible to avoid some troubles, timely relief of pressure, can reduce hair loss, avoid the occurrence of “melanin” reduction, people’s hair will not be prematurely white. Focus
