Medical Net (Medical Network) published Dietary Supplements: Are You Throwing Money Away? (Dietary Replenishment: Are you throwing money away?). The author is Dennis Thompson. I translate it as follows:
A new HealthDay/Harris poll shows that most Americans believe in dietary supplements. Nearly 3 out of four people take a supplement daily, but many mistrust the effectiveness of these supplements because in fact they don’t help people live longer or healthier, says Thunder Jalili, director of nutrition graduate and undergraduate research at university.
{He pointed out: "There are many sounds of effective marketing around supplements, because people want to believe and find useful products, so marketing is to cater to people's needs."
What's worse, people also believe that the United States has strictly supervised the supplement industry, but this is not the case. HealthDay/Harris poll found that about half of American adults (49%) mistakenly believed that most of the available dietary supplements have been declared safe and effective by the U.S. FDA. Only about a quarter of people know that these supplements entered the market without FDA's prior review.
In addition, a public opinion survey found that one in three mistakenly believed that the government did not allow the sale of potentially dangerous supplements in the United States. "In fact, supplements are not under supervision at all. The FDA does not have legal authorization or personnel or resources to really pay close attention to everything, and they don't have a good execution mechanism," Jalili told HealthDay Now: "They may find unsafe ingredients or supplements, and they can send letters and contact manufacturers, saying, "We want you to pull out these ingredients, or we want you to recall these supplements. But at the very end, many companies don't do this, and there is no real specific law to let them do that."
Still, the poll found that about nine out of 10 people taking supplements believe the supplements they take are safe for them, and about half of them agree very much. In fact, the results of the public opinion survey showed that most people (56%) believed that supplements were safer than medications. Kathy Steinberg, deputy president of the Harris Popular Survey, said: "Although the FDA has been more publicly concerned over the past few years than ever, consumers seem to have misunderstood the role of the agency in how to review the safety of supplements." The survey found that the three most commonly taken supplements for adults are comprehensive vitamins (35%), vitamin D (31%) and vitamin C (26%). But Jalili said there is no science supporting their use.
Jalili said: "In the past 20 to 25 years or so, scientists have conducted many large-scale comprehensive vitamin trials. Their idea is that if we supplement vitamin E, vitamin A, vitamin C alone, we can reduce the risk of heart disease, reduce the risk of death, and reduce the risk of certain cancers. These studies may have recruited millions at this point, and they basically found that these vitamins don't really work at all. Not only that, in some populations, they actually increase the risk of injury and increase mortality. ”
Jalili adds that other studies that tout multiple vitamin benefits were done in a controlled laboratory environment, which does not reflect real life. "Suppose there are some data in half of the supplements that show they have done something, but the problem is that most of these data are derived from cell culture or animal modeling experiments. They are manifested differently from complex humans. Therefore, it is even more difficult to figure out which ones may work and which ones may not work."
Jalili said that vitamin A (4% β-Hussar) and vitamin E (15%) have been determined to be harmful to humans, and the US Preventive Services Working Group recommends not to use them.
Even recently, a study published last week in the New England Journal of Medicine found that vitamin D supplements have no effect on improving bone health and preventing fractures. The experiment found that middle-aged and older people who were randomly assigned to take large amounts of vitamin D daily had about the same rate of fractures as those who took comfort drugs.
Food is the best source of vitaminsJalili said that it is much better for people to get nutrition from food. He used ginger yellow as an example. Ejaculation is a nutrient with anti-inflammatory properties and can be used as a supplement. When ginger yellow is taken as a pill, it is difficult for the body to handle it. "We might take 500 mg or 1,000 mg of ginger yellow, but it absorbs little. But when we use ginger yellow in Indian curry, cook and cook, it has the chance to become more bioavailable. Then we eat curry, there is something else in the curry, other nutrients, and a lot of things together is actually a better combination."
Popular survey found that although people generally believe in supplements, the public also recognizes their potential harm and disadvantages.. Public opinion surveys show that nearly two-thirds of adults know that supplements can have negative effects on prescription drugs. Three-quarters say taking too much of some vitamins may be harmful to health, and 61% agree that taking more supplements may not necessarily improve their health. The survey found that it is important that more than four in five adults agree to discuss supplement use with their doctor. But your doctor may not be the best source of information about supplements. Jalili said: "The hospital does not require special nutrition training. Overall, many doctors have received some basic nutrition training, but are not really advanced training. So, is your doctor a good source of nutrition information determined by that person. If that person is really interested in nutrition and spends time educating himself, then they can become an important source of nutrition advice."
