The report on nutrition and chronic diseases of residents in China (20 15) shows that with the improvement of living standards, the dietary structure of people in China has changed greatly, and the proportion of vegetables and fruits intake has dropped significantly, and it has been replaced by a high-calorie and high-fat diet. The consequence of this is that it is very easy to lack nutrients, such as vitamin A, vitamin D, calcium and iron. As we all know, vitamins and minerals are very important and necessary to maintain the normal metabolism of the body. Lack of vitamins and minerals will inevitably lead to metabolic disorders and diseases. In fact, there are many similar products. Who can eat them for a long time? Will there be side effects?
What is missing and what is supplemented is the most reliable.
Special people, when the demand for nutrients increases and the diet may not be satisfied, need to be supplemented. For example, for pregnant women, folic acid supplementation is generally recommended. If you feel that your diet is not reasonable enough, it is ok to keep one tablet a day. For middle-aged and elderly friends, calcium and phosphorus should be supplemented appropriately. Under a normal diet, a single nutritional supplement is enough.
Some friends just don't like fruits and vegetables, and want to supplement nutritional supplements. In this case, targeted supplements can be considered. However, it should be emphasized that nutritional supplements are only a supplement and can never replace normal diet.
Can I eat it for a long time? Are there any side effects?
Let me give you an example first. Good storage contains 5000 international units of vitamin A, while normal healthy people can fully meet their needs by ingesting 2000~3000 international units of VA every day. Of course, this dose, one tablet a day, is no problem, and it is still far from the toxic dose. But don't overlook an important issue. Vitamin A is a fat-soluble vitamin. If it cannot be over-metabolized, it will easily accumulate in the body. If you take it in such a large amount for a long time, it is prone to poisoning symptoms.
Healthy adults should choose according to their own health. For example, people with high blood calcium content will take extra vitamins and consume a lot of calcium, which will easily lead to problems such as stones, constipation and hypercalcemia.
If you take extra supplements while eating normally, it will actually increase the burden on the liver and kidney. This kind of influence is illegally estimated in a short time, which varies from person to person.
If only from the nutrient itself, it may not be a problem for healthy adults to eat for a long time, and it is understandable to spend money on it. But considering the raw materials, some impurities are not detected at all. For example, the incident that valsartan detected carcinogens some time ago is a good example. I dare not say whether there are heavy metals exceeding the standard, whether it is easy to accumulate in the body and cause chronic poisoning, and whether preservatives are harmful to the body.
Dr. Buyao believes that if it is not necessary for the body, you can't eat these dispensable drugs or health products for a long time. For drugs, it is always when the benefits outweigh the risks that they will choose to use or use for a long time. Brief introduction of Dr. Yao
