Fish-oil supplements are now so popular that as many as one in five people take them regularly, according to the latest National Diet and Nutrition Survey.
You can see why, with claims that the pills can prevent a multitude of disorders, from Alzheimer’s to Zellweger syndrome, a rare hereditary disorder. However, the idea that a single dietary component taken in such small doses should have such widespread effects is, in my opinion, laughable. Rather than a passport to good health, fish-oil pills are more like snake oil.
