2018 American Medical Association Journal article: Nutritional supplement recommendations that healthcare professionals must know . Pointed out : In addition to some specific ethnic group will recommend specific supplementary nutrients outside , nutrition supplements for non-nutritional deficiency disorders, there is no benefit .
Nutrition supplements the general population does not benefit means that, unless the system because of the lack of certain nutrients (such as lack of vitamin C can cause scurvy and even bleeding gums), Department outside of nutritional supplements is beneficial Link circumstances under other circumstances and more eat any kind of nutritional supplements are of no benefit , and may even be harmful.
Many people take supplements today, but most trials have not found any benefits of vitamins and minerals for "chronic diseases unrelated to nutritional deficiencies". Instead, some studies have shown that supplementation of micronutrients that exceed the recommended intake (RDA), such as high doses of beta carotene, folic acid, vitamin E or selenium, may be harmful to health, including increased mortality, cancer and hemorrhagic stroke. Medical staff should advise patients that supplements cannot replace a healthy and balanced diet . Medical staff should also tell patients that the micronutrients in food are generally better absorbed by the body and have fewer potential side effects. A healthy diet provides a series of nutritionally important substances in a highly concentrated form with biologically optimal proportions. In fact, studies have shown that a good diet pattern is more helpful to health than a single intake of nutrients .
Which ethnic groups may need nutritional supplements?
What nutrients are easily lacking in daily diet?
In addition to the unbalanced diet mentioned in the article, here we supplement the main source of each nutrient. Although eating more nutrients is not beneficial, if you encounter a state of deficiency, nutritional supplements are still useful. If you find that you don't often eat the main source of this nutrient, or can you try to get it from your diet first. But if it is really not possible, perhaps you can consider using nutritional supplements.
The key points that JAMA wants to say to medical staff in this study
When reviewing the patient's medication, the clinician should ask whether other nutrients (and plants or other diets) are used to explain potential interactions. For example, vitamin K supplementation will reduce the effect of anticoagulants such as warfarin, and vitamin B7 will affect the accuracy of cardiac troponin and other test data. In addition, in the United States, they will suggest some interactive websites that are convenient for people to inquire and use, such as drugs.com, WebMD or pharmacy websites, which can be used for free.
Clinicians and patients should also be aware that the US Food and Drug Administration (FDA) is not authorized to review the safety and effectiveness of dietary supplements before marketing. Although nutritional supplement manufacturers must comply with "GMP" (Good Manufacturing Practice) regulations, the monitoring is not ideal. Therefore, if possible, we hope that clinicians can prescribe products that require a prescription, or suggest that patients consider choosing supplements that have been certified by (ConsumerLab.com, US Pharmacopoeia, NSF International or UL) (marked clearly with the active ingredient dose and not Contains microorganisms, heavy metals or other toxins). Clinicians (or patients) should report suspected supplement-related adverse reactions to the Food and Drug Administration through MedWatch (a website similar to adverse reaction notifications). The website of the National Institutes of Health Dietary Supplement is a source that can help doctors and the public understand many micronutrients and other dietary supplements. The article also hopes that medical staff will promote the correct use of nutritional products to the public. These efforts will improve the health of the public.
