Pillbox Fallacy

What is the debate?
In an article in the Journal of the American Medical Association, researchers found that relying on vitamins and supplements for nutritional balance may do more harm than good by giving people the false impression that a healthy diet isn8217;t needed. 8216;8216;People think even if you don8217;t eat properly, supplements will do the job,8217;8217; said Dr Anoop Misra, Professor of Medicine at AIIMS.

Is that the only risk?
The problem is not as simple in certain areas. Recent studies have shown that many supplements have a tendency to increase the risk of diseases over the years. 8216;8216;When vitamins are taken without mixing it with any other supplement, they are not harmful and might even be needed in some cases. But studies have shown that the risk of diseases increase with the consumption of nutritional supplements,8217;8217; said Dr Misra.
An overdose of various supplements could result in:
8226; Beta carotene supplements increase the risk of lung cancer
8226; Vitamin E increases the risk of cardiovascular diseases; mostly in smokers
8226; High doses of vitamin A can cause osteoporosis and foetal malformation
8226; Vitamin C can lead to stomach pain, diarrohea and gas
Apart from what your body needs, the supplements also contain harmful substances. And even while some supplements such as calcium and vitamin D are helpful for maintaining bone health, mixing these with massive amounts of other supplements can cancel out the benefits:
8226; Calcium inhibits heme and non-heme iron absorption
8226; Iron inhibits zinc absorption
8226; Zinc inhibits copper absorption
8226; Vitamin E negates vitamin K action

Are supplements very harmful?
Not always, say the experts. Some people need supplements. 8216;8216;Certain supplements are essential and more so in the Indian context,8217;8217; says Dr Misra.
