The US Preventive Services Working Group released a research report on the 24th that there is not enough scientific evidence to show that taking multivitamin or other nutritional supplements can prevent heart disease and cancer.
After a multi-year systematic scientific study, the US Government-funded Preventive Services Task Force concluded that the claim that multivitamins or other nutritional supplements can prevent heart disease and cancer lacks sufficient scientific evidence and that some previously thought Effective nutritional supplements even "do more harm than good."
"Too many people have spent too much money on vitamins. They think they are good for themselves," said Virginia Moyer, co-chair of the Preventive Services Working Group.
The Preventive Services Working Group said that it can be confirmed that vitamin E can not prevent heart disease and cancer. Regarding whether taking one or more vitamins will help reduce the risk of heart disease and cancer, at least current scientific research cannot provide sufficient evidence.
In addition, beta-carotene, previously thought to be effective in preventing these two diseases, has proven not only to be ineffective, but also to do more harm than good for certain groups of people. "For those who are at risk of lung cancer, such as smokers, taking it will increase the odds of illness," said working group co-chair Michael Lefeffer.
Agence France-Presse said that the report of the Working Group on Prevention Services may seriously hit the US $ 28 billion worth of vitamin pharmaceutical industry. In the United States, surveys show that about half of adults take dietary supplements at least once a day, and one in three people claim to take multiple vitamins daily.
The advice provided by the working group to healthy adults is that vitamin supplements do not have to be added. Instead, dietary habits should be changed, with emphasis on low-fat health recipes, eating more fruits and vegetables, whole wheat products and seafood.
