An Apple a Day

We (the authors and editors) at SBM get accused of many nefarious things. Because we deliberately engage with the public over controversial medical questions, we expect nothing less. It goes with the territory. In fact, if there were a lack of critical pushback we would worry that we were not doing our job. Still, it is disconcerting to see the frequently-repeated ideological...

Do vitamins prevent cancer and heart disease?

It is a triumph of marketing over evidence that millions take supplements every day. There is no question we need vitamins in our diet to live. But do we need vitamin supplements? It’s not so clear. There is evidence that our diets, even in developed countries, can be deficient in some micronutrients. But there’s also a lack of evidence to demonstrate that...

New concerns about the safety and quality of herbal supplements

If there is one aspect of “alternative” medicine that both critics and fans should agree on, it’s that products should be manufactured to high standards. What’s on the label should accurately describe what’s in the bottle. Product quality standards are essential, whether you’re using herbs or drugs. And when it comes to ensuring the products we buy are of high quality, we’re...

What’s in your supplement?

When you pick up a bottle of supplements, should you trust what the label says?  While there is the perception that supplements are effective and inherently safe, there are good reasons to be skeptical. Few supplements are backed by good evidence that show they work as claimed. The risks of supplements are often not well understood. And importantly, the entire process of...

Who takes dietary supplements, and why?

If you’re a regular reader of this blog, I’ll bet you’re not a regular consumer of vitamins or supplements. I’m in that group. Aside from sporadic vitamin D in winter, I don’t take any vitamins or supplements routinely, nor do I give any to my children. Your reasons may be close to mine: There is little to no evidence suggesting that dietary deficiencies...

Tom Harkin, the NCCAM's biggest supporter.

Congress will soon lose its foremost supporter of quackery, but will it matter?

I don’t much like Senator Tom Harkin (D-IA), and, I daresay, neither do any of my fellow bloggers here. The reason should be painfully obvious. Arguably, no single elected official currently serving today (or ever) has done more over a longer period of time to promote quackery in the United States. I make this harsh assessment because Senator Harkin was the legislator...

Andrew Weil/AAFP Article Rejected by Slate

I was asked to write an article for Slate, the on-line magazine, about Andrew Weil’s selection as the keynote speaker for the 2012 AAFP annual scientific assembly. The science and health editor, Laura Helmuth, was initially enthusiastic about what I wrote, but eventually decided not to publish it. Here is the initial draft of my article. My comments follow. Original Draft of...

Rejecting cancer treatment: What are the consequences?

One of the points I’ve tried to emphasize through my contributions to Science-Based Medicine is that every treatment decision requires an evaluation of risks and benefits. No treatment is without some sort of risk. And a decision to decline treatment has its own risks. One of the challenges that I confront regularly as a pharmacist is helping patients understand a medication’s expected...

Bee Pollen Supplements – Not Safe or Effective

Among the myriad of supplements being offered to the public are various bee products, including bee pollen. The claims made for bee pollen supplements are typically over-hyped and evidence-free, as is typical of this poorly regulated industry. The claims from bee-pollen-supplements.com are representative: The benefits are enormous and the substance has been proven by many health experts. This particular substance is known...

The Marino Center for Integrative Health: Hooey Galore

Two weeks ago I promised that I would discuss the Marino Center for Integrative Health, identified in the recent Bravewell report as having a “hospital affiliation” with the Newton-Wellesley Hospital (NWH) in Newton, Massachusetts, which is where I work. I also promised in that post that I’d provide examples of ‘integrative medicine’ practitioners offering false information about the methods that they endorse. I’d...
