Nutritional supplements are popular in the West Experts point out that trace elements or "food supplements" are the most reliable.

In recent years, after eating a variety of functions of nutritional supplements, it seems to have become a lot of people's choice. At the time, people pay more and more attention to health needs, how to eat properly, how to supplement nutrients and other issues have become the focus of people's attention. Is it necessary for the average consumer to take vitamins, minerals, and various dietary supplements in addition to daily dietary intake?

Explain nutritional supplements as explained in Food Nutrition, published by China Light Industry Press: Nutritional supplements are an auxiliary means of diet to supplement the amino acids, trace elements, vitamins, minerals, etc. needed by the human body. Nutritional supplements may consist of amino acids, polyunsaturated fatty acids, minerals and vitamins, or only one or more vitamins, or one or more dietary components, in addition to amino acids, vitamins, minerals and other nutrients, can also have herbs or other plant components, or the above components of concentrates, extracts or compositions.
The Health Effects of Vitamin and Mineral Supplements, including multivitamins, minerals and fish oils, were evaluated by four researchers from Qingdao University's Institute of Nutrition and Health, Li Wei, and four scholars from the United States, the United Kingdom and Canada, in the British Medical Journal (BMJ).
study found that more than 70 percent of adults over the age of 65 in the United States use nutritional supplements, compared with one-third of children and adolescents. American researchers in the study estimated that 5 percent of people ate too much micronutrients, and 80 percent and 97 percent of children in the U.S. and Canada were overestimation with vitamin A. More women than men use nutritional supplements. The most widely used nutritional supplements are vitamin C, vitamin E and vitamin D, followed by vitamin B12, vitamin B6 and calcium.
results show that vitamin, mineral and fish oil supplements are not supported to reduce the risk of noncommunicable diseases, according to the previous paper. The use of nutritional supplements has significantly reduced the underemployment of most nutrients but has also increased overeating of certain nutrients, and further studies are needed to assess the long-term health effects of nutritional supplements on the health of the general population and individuals with specific nutritional needs, including those from low- and middle-income countries.
"Nutritional supplements, represented by vitamins C, E and D, are popular in the Western world, but are not widely used in China," he said. Song Qing, a professor at the School of Chemistry and Bioengineering at Beijing University of Science and Technology, says micronutrients are most naturally replenished through food, and that rigorous scientific clinical trials have failed to come to a final conclusion on the wide range of therapeutic functions of these vitamin supplements.
" results from randomized controlled trials showed that for healthy people without nutrient deficiencies, eating vitamins, minerals, fish oil capsules, and no effective reduction in cardiovascular disease, cancer, or type 2 diabetes was found to be effective. Fan Zhihong, an associate professor at the School of Food at China Agricultural University, said.
effect varies from person to person, take the quantity, time to consider
nutritional supplements in the end whether to eat it? Fan Zhihong said, to analyze the specific situation on the basis of decisions, and the amount of supplements should be reasonable, large doses of nutritional supplements do not take too long.
"There are still a lot of people who are not really 'healthy people' and may not be able to guarantee 'adequate nutrients from natural foods on a daily basis', and may need to pay attention to supplementing certain nutrients in the short term,"
said. Fan Zhihong said.
Song Qing from the chemical structure to assess the benefits of micronutrient supplementation.
" vitamin C is an essential cofactor for several important enzymes, but humans and most primates cannot synthesize themselves, so they must be ingested from food. Vitamin C is also a water-soluble antioxidant in the body. The body's energy comes from burning chemicals, which damage cellular structures, and antioxidants can reduce combustion damage. Song Qing said.
, vitamin E is a fat-soluble antioxidant in the body. The antioxidant effects of vitamins C and E are determined by their respective chemical structures, so aging caused by oxidation of cellular structures can theoretically be delayed by antioxidants such as vitamins C and E.
vitamin D is a synthesis of cholesterol from ultraviolet light and is essential for bone health. But vitamin D is a class of sterol hormones that bind tightly to a wide range of subjects throughout the body, so physiological effects are not limited to bones. In recent years, animal and clinical experiments have found that vitamin D can affect many physiological activities. Vitamin D supplementation can improve immunity against a variety of diseases. Song Qing pointed out.
Song Qing said that although vitamin C, D, E-specific chemical structure to ensure its strong health function, but through dietary nutrition supplements whether additional supplements are beneficial, need to be considered comprehensively. If there is already enough food in your intake, additional supplements can increase the cost of living. For special groups of people, such as athletes, dieters, the elderly, patients with chronic serious diseases, vitamin supplementation and other micronutrients are a strong guarantee to maintain or restore physical health.
