The population of youth in China is a dynamic level. Generally speaking, it is said that the work pressure is high. Many people suffer from insomnia and sleep poorly at night. Therefore, they have the habit of taking vitamins, and even take multiple capsules of vitamins a day. In fact, it is not just office workers. There are many types of vitamins sold on the market, because they are from children to silver hair consumers. People who are loved by nationals are Vitamin B group, which believes that taking can enhance physical strength, promote immunity, and protect nerves. Still remember the TV refreshing drink ad? He was extremely physically strong, and he drank the vitamin-containing drink and immediately came back to life! The myth of vitamins comes from media information or "mouth transmission" by friends. For example, when you look at computers and smooth tablets every day, it is easy to hurt your eyes, and taking vitamin A can protect your eyes from injuries; when you get old, bone loss is prone to loosening and fractures, and you don't have enough supplements and supplements, and you have to eat vitamin D every day! There is also vitamin C. Eating more can promote the growth of the gel and have a skin-whitening effect! Indeed, proper vitamin supplementation can promote physical health, but does it need to be supplemented every day? And does everyone need additional vitamins?
What is vitamin? Vitamin (or vitamins) is one of the trace nutrients we need in our bodies. Compared with trace nutrients, huge amounts of nutrients are the oils, sugars and proteins contained in the daily diet. After digestion and absorption, it is used to maintain the body's new body and provide all the energy (heat) required for life operation. As for vitamins, the human body demand is not high (the name implies trace nutrients), which itself does not supply energy, but is used as a "coenzyme" or "cofactor", helping the new Chen Dae-Telephone reaction to promote energy production (vitamin A, E, K, C, B groups), and at the same time plays the role of scavengers (vitamin E, C) to eliminate oxidative harmful substances (free radicals) produced by the scavenger process. Sometimes vitamins also have the function of cholemones (vitamin A, D), which can maintain human body balance, such as skeletal system and blood calcification. If the human body is a treasure chest of energy, then vitamins are undoubtedly the key to open the box and are indispensable. Based on the above concepts, only when we have a balanced and sufficient diet, the body has "fuel" to "burn", and the existence of vitamins is intentional.
Except for vitamin D, which can be produced by the skin through the sunshine process, other vitamins must be obtained from the outside world. Even so, the body has a certain amount of vitamin stocks, which can be used by healthy people for weeks to years, unless long-term poor nutrition, such as developing Chinese dietary orders, lack, or poor kidney function, and the elderly, as well as specific diseases or physiological conditions such as chronic abdominal cavity, kidney washing, pregnancy, and breastfeeding, generally healthy people do not need additional vitamin supplements as long as they can eat normally.
The Ministry of Welfare has a designated dietary nutrition reference intake scale (DRI) for nationals according to different ages, which can meet the daily vitamin needs of most (97% ~ 98%) of healthy people. Vitamine itself is a natural thing, but after purification, it can be prepared with high doses and is classified as a drug (Table 1) and must be established by the doctor. Some vitamins are overloaded with excessive amounts of vitamins. Unless they have been evaluated by doctors, if the public buys healthy foods in the shop by themselves, they need to pay attention to the daily intake (Table 2). For example, vitamin C can increase oxalic acid removal from urine. Using too much will increase the risk of kidney stones. Excessive vitamin D content in the body will increase the absorption of calcification by the kidney and promote the calcification of bones, causing hypergalactia-related symptoms. Vitamin A can cause damage to the fetus when pregnant women are used.
However, taking specific drugs may also increase the risk of vitamin deficiency. For example, Metformin, a drug for type 2 diabetes, is generally used as a first-line drug for type 2 diabetes. However, this drug will interfere with the absorption of vitamin B12 at the end of the kidney and kidney. If the drug is taken at a high dose for a long time, about 30% of patients will suffer from B12 malabsorption. Vitamin B12 lack not only affects the blood circulation caused by red blood cell division, but also affects the health and information transmission of neuromyelin, and leads to neuropathy. It is worth noting that diabetic patients are prone to diabetes because their neuronal cells are immersed in high-sugar environments for a long time. When patients experience neurologic related symptoms, they should clarify whether they are poor blood sugar control or nutrient deficiency.
In addition, ionic supraphic inhibitors (PPI) that inhibit gastric acid secretion reduces gastric acid and intrinsic factors (Intrinsic factor) secretion by gastric wall cells. Gastric acid is responsible for breaking down B12 in food, and the inherent factors will form complexes in the kidney and B12 to help B12 absorb. Without these two necessary factors, vitamin B12 in food cannot be used properly. However, people who use Metformin or PPI should not be overly worried because vitamin B12 has sufficient resources in our liver, which is enough for us to use it for several years. B12 mainly comes from meat foods (especially liver), and a small amount comes from beans, grains, eggs and dairy products. Most people will not suffer from normal diet.. There are actually many examples of drugs affecting vitamins. This is mainly to remind the public that high dose of vitamins is also considered a drug. If you think it is necessary to use it, you should consult a doctor, nutritionist, and pharmacist first. Unless the disease is due to vitamin deficiency, vitamin replacement should not be treated properly. In addition, some of the commercially available vitamin-containing beverages contain alcohol, which can affect the absorption of vitamins by the kidneys. In addition, excessive alcohol is harmful to health, so you should take it with caution.
