Recently, the Journal of the American Medical Association published an article titled “Why Do U.S. Adults Use Dietary Supplements?”

I’ve asked the same question myself. I’ve noticed so many people that seem, to me, to be popping pills left and right that they don’t need.

I’ll grant you that some supplements are useful. For example, I recommend a multivitamin for everyone every day, although many of my colleagues poo-poo it. But some people are taking a handful of pills and capsules every morning.

The researchers discovered that most supplement takers are educated, exercise more, eat better and drink less than the overall population. They are more likely to engage in wellness activities. Now, I don’t think the “supplements made them do it,” but rather that they’ve taken the route of “I want to be as healthy as I can.”

Congratulations and kudos, I say. But are the supplements necessary? This question is especially important, since supplements may have a downside.

I used to say if you want to spend your money in the supplement aisle, go right ahead – I’ll stay with fruits and vegetables, thank you. I also said that it was a “no harm, no foul” situation, as supplements were safe.

Well, guess what? I was wrong.

Let’s begin with my first wake-up call – beta-carotene. I used to recommend taking it to prevent cancer because we know that people who consume foods rich in beta-carotene such as broccoli, squash and carrots, for example, have less cancer.

Then a major study (conveniently labeled the CARET study, for Beta-Carotene and Retinol Efficacy Trial) showed that smokers who took beta-carotene and continued to smoke actually had more lung cancer. That’s right! Beta-carotene supplements somehow encouraged cancer.

Since that time, this once-hot supplement has cooled down. You rarely hear anyone touting its usefulness anymore.

When I started recommending against beta-carotene, you should have heard the angry letters that flooded my inbox. I was accused of being in bed with the FDA, of being a pill pusher (aren’t supplements in a pill form?), of being a charlatan, or just plain dumb. That’s when I realized that for some people, supplements are akin to a religion.

I started recommending that people spend more money in the grocery store and less in the drug store. My general rule of thumb is color; the deeper and more colorful the fruit or vegetable, the more loaded it is with vitamins, minerals and other nutrients such as beta-carotene and antioxidants. Fresh is best, followed by frozen and then canned.

So back to the idea of “it can’t do any harm, so take it” that I used to believe.

My spin: Manufactured supplements, even those that are labeled natural or organic, are never natural, because Mother Nature never made a pill in her life. Stick by her side and you’ll be peachy keen.
