Advertisement of gorgeous models persuading TV watcher the benefits of dietary supplement tend to be seen very often. How can we recipient know whether they are telling the truth?
On one hand, some nutritionists claim that dietary supplement, also known as nutritional supplement, providing vitamins, minerals, or fiber, is not necessary. Daily healthy diet with sufficient fresh vegetables and fruits will satisfy the nutrients the body needs. It is also believed that consuming an excessive of vitamins risks for liver disease. Moreover, these surplus vitamins are finally eliminated.
On the other hand, some experts say that having fast food or packaged food for a long time leads to nutrition deficiency. Environmental pollution, our lifestyle, and stress are likely to cause health damage as well. Although dietary supplement cannot replace daily food, it offers vast array of vitamins and mineral supplements that help, for instance, to keep bone strong (calcium and magnesium), to regulate nerve system (vitamin B), and to prevent skin from dryness (fish oil).
Since this contradiction is hard to prove and there is very little evidence that supplementation would be helpful, one should consider carefully whether to take dietary supplement.
