Trace elements are still the most reliable food supplements

years, after a meal to eat a variety of functions of nutritional supplements, it seems to have become a lot of people's choice. Now 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?Food Nutrition, published by China Light Industry Press, explains nutritional supplements as an aid to diet, supplementing 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 may be composed of one or more dietary components, in addition to amino acids, vitamins, minerals and other nutrients, can also have herbal 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 assessed in a paper published in the British Medical Journal (BMJ) by Li Wei, lead professor at Qingdao University's Institute of Nutrition and Health.
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 overestimanted 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. Song Qing, a professor at the School of Chemistry and Bioengineering at Beijing University of Science and Technology, said micronutrient supplementation is most natural 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.The results of the
-related randomized controlled trial showed that for healthy people who did not show a lack of nutrients, it was good to eat vitamins, minerals, fish oil capsules, and none of them were found to be effective in reducing the risk of cardiovascular disease, cancer, or type 2 diabetes. Fan Zhihong, an associate professor at the School of Food at China Agricultural University, said.do you want to eat any nutritional supplements? Fan Zhihong said that to analyze the specific situation on the basis of decisions, and the amount of supplements to be reasonable, large doses of nutritional supplements do not take too long.
"There are still many 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." 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 burn 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 vitaminSC 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 enough food in your intake, the extra supplement will 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.
