What’s The Deal with Vitamin Supplements?
A priest and an atheist were sitting next to each other on a flight. They spent most of the time arguing their respective positions when suddenly the captain notified the passengers that the engines are burning and the plane is about to crash. As the plane nosedived, the priest began to fervently pray. He couldn’t help but notice that the atheist was praying too. “I thought you don’t believe in god,” he asked. “I don’t,” answered the atheist, “but it sure won’t hurt to try…”
It seems like “won’t hurt” is what many people say about supplementing. They’re not really sure, but aggressive marketing combined with less than optimal nutrition as a result of junk food, leave many people opting for the “extra insurance”.
Are supplements just a placebo? According to two recent article in the Washington Post and Reader’s Digest, vitamins and supplements don’t contribute to improved health, and according to some studies may actually cause damage:
Megadoses of E, for example, can increase the risk of bleeding if you’re already on heart meds like blood thinners. An earlier 2004 analysis by Johns Hopkins researchers found consuming 400 IU or more of vitamin E a day alone (some products on the market today contain 1,000 IU per capsule) was associated with a higher risk of dying and should be avoided. (One theory says high doses may alter your natural immune function and actually become pro-oxidant.) Taking too much niacin without a doctor’s okay can lead to liver damage and other problems over time. And too much vitamin A increases the risk of liver and lung cancers, and can cause birth defects and reduce bone density.
The supplement industry does not like bad reviews that could hurt the $7.5-$10 Billion a year business. And it seems that many people dearly want to believe that vitamin pills are their savior – have an unhealthy day, munching away on junk food and slurping cola, but redeem yourself with a multivitamin for dinner.
Without getting into the debate on the efficacy or not of these pills, let’s think for a minute about the nomenclature – supplements. A supplement is something that may be added, not something that replaces real nutrients from whole foods. Eating pizzas and burgers all week long and then supplementing will NOT make you healthier.
And despite our understanding of how individual vitamins interact with the body, there are thousands of additional nutrients in each fruit or vegetable that science has yet to fully understand. Not to mention how they all work together. Isolating a few of the nutrients while disregarding the others may be the reason that many of the promises on the supplement packaging never come true.
The American Dietetic Association recommends we get our nutrients from food, not pills. There is leeway for people with certain deficiencies as well as a general recommendation to get vitamin D for those of us who live in dark cold regions of the country, without too much sunlight in the winter. But that does not justify the existence of entire aisles in pharmacies for insta-pills.
What to do at the supermarket:
Buy lots of fruits and vegetables. If you think they’re too expensive, consider the extra $$$ as money not spent on supplements, medications, and future doctors’ visits. You can buy frozen produce at lower prices. Canned goods are also an option, but watch out for high levels of sodium.
