In the Yellow Emperor’s Canon of internal medicine, “Su Wen · Bi Lun” said: “diet doubles, and the intestines and stomach are injured.” Su Wen · Ju Tong “said:” labor leads to gas consumption. “This shows that Chinese medicine realized very early that people’s sub-health is related to people’s bad lifestyle and habits. Modern medicine believes that in order to improve the sub-health state of the human body, we should pay special attention to the diet rule, reasonable structure, regular life, combination of work and rest, strong abstinence from smoking and alcohol, and proper exercise, so that people can return to the healthy state through scientific and reasonable adjustment.
Diet plays a key role in regular living habits. People should pay attention to vitamin supplementation while choosing diet. Relevant studies have proved that vitamins play an important role in maintaining human health. This is because although vitamins are not the raw materials that directly constitute the human body, nor can they directly provide the energy that the human body needs, they play a key regulatory role in the process of material metabolism. It is a component of many coenzymes in the human body, which determines whether many chemical reactions in the human body can proceed smoothly. The human body does not have much demand for vitamins every day, but once it is lacking, it will cause obstacles to the metabolism of human substances, affect the health status, and then cause sub-health conditions.
According to the survey, more than 50% of the population in China is deficient in vitamin A or D, and vitamins B1, B2 and C are generally deficient, especially the middle-aged and old people. We can conduct self-test on the symptoms caused by lack of different vitamins, scientifically recognize our physical health, appropriately supplement the vitamins we lack, and resist the invasion of sub-health. So, what is the effect of each vitamin on the human body?
Vitamin A is called “beautiful vitamin with bright eyes and bright teeth” This is because its main role is to maintain the healthy growth of skin, hair, bone and mucosa, and enhance vision and reproductive function. Vitamin A only exists in animal foods, and there is no vitamin A in plant foods. Only the precursor of vitamin A can be changed into carotene of vitamin A in the human body.
Vitamin D, vitamin D deficiency usually occurs in infants, pregnant women and lactating women from 2 months to 1 year old after birth. Once children lack vitamin D, they are prone to rickets. The easiest way to supplement vitamin D is to get in the sun. Because there is a substance in human skin called “7-dehydrocholesterol”, which can be converted into vitamin D under ultraviolet radiation and used by the human body. Of course, taking more cod liver oil, egg yolk and liver is also very good.
Vitamin B1 is the highest in grain products with germ and bran. Now pasta is refined and processed, so most of vitamin B1 is lost in the processing, which is a pity. No wonder some nutritionists said: “in the past, the food of poor people was rich in vitamin B1. Now that people are better off, their nutritional level is not as high as that of the poor people in the past.”
The main source of vitamin B2 is animal liver, as well as eggs, milk, meat, fish, green vegetables, beans, etc. In China, the content of vitamin B2 in the dietary structure is less, which can only reach half of the standard, especially in the off-season of vegetables, which is very serious. Therefore, vitamin B2 deficiency is common in China.
Vitamin C is the main raw material for the formation of intercellular matrix. Its main role is to connect cells, maintain the normal functions of teeth, blood vessels, bones and muscles, promote wound healing, and enhance insensitivity to diseases. The most common deficiency of vitamin C is gum bleeding and subcutaneous punctate bleeding.
Vitamin deficiency will lead to decreased physical fitness, reduced immunity and easy illness. Therefore, the body is in a sub-health state and needs to be supplemented with vitamins appropriately, but it is not allowed to supplement blindly. It is best to test first and make a specific decision after understanding the physical condition.
