This is not the first time I have written about the waste and potential dangers of dietary supplements. The last entry on the subject of supplements in general was about two years ago where I quoted from the New York Times saying that annual spending in America averages about $100 per person. I focused on vitamin and mineral supplements as recently as last September. I was hoping after many attempts to have wrapped it up, but it’s good advice, so I will give it another shot based on some fresh headlines.
About two weeks ago researchers from West Virginia University School of Medicine published a study in the journal Annals of Internal Medicine showing “that although reduced salt intake and certain supplements may lower the risk of cardiovascular diseases, most nutritional supplements do not improve the risk for heart disease or death.”
An article reviewing that study quotes the lead researcher: “The reason we conducted this study was that millions of people in the United States and across the world consume supplements or follow certain dietary patterns, but there was no good-quality evidence to suggest that these interventions have any effect on cardiovascular protection."
The study itself was not a clinical trial but a review of 277 other studies with a total of nearly one million subjects. It looked at the effectiveness of many popular nutritional supplements and 8 diets. “Findings show that of the 16 dietary supplements, only two showed beneficial effects on heart health, namely omega-3 long-chain fatty acids and folic acid….[whereas] selenium, vitamin B6, vitamin E, vitamin C, iron, and vitamin A, among others, show no significant effect on heart health.”
Other important findings were that some supplements by themselves, not just the tainted ones that appear in the news from time to time, are potentially harmful. Another surprising finding was that “most diets, like modified fat intake, the Mediterranean diet, and reduced saturated fat intake, had no effect on the heart at all.”
Some other sources reporting on the same study had more watered down headlines. This one says, “For Heart Health, Some Popular Supplements Aren't as Helpful as We Thought.” But the sub-headline is more direct: “Consumers should ‘stop wasting their money on these products.’ ”
Another one is even more careful in its wording: “Nutritional supplements and diets not always protective, research suggests.” But they did provide a link to another study from 14 months ago that also came to the conclusion that “most commonly consumed vitamin and mineral supplements provide no consistent health benefit.”
The final conclusion as always is “only eating a healthy balanced diet is the key to overall health.” That shouldn’t come as a surprise to anyone who has been paying any attention to and looking into health news over the years. Once again, it’s looking for the easy, magical answers that cause us to waste time and money on pills and fad diets. Avoiding that mindset is, though, an easy way to come up with some extra money for that problematic retirement savings plan.
