Lifestyle Medicine: Have Hammer, See Nails, Seeking Spoon

(0) Comments | Posted August 27, 2014 | 11:25 AM

Lifestyle is the best medicine. The perennial challenge is figuring out what makes the best spoon.

I suppose I might be prone to bias on this topic. Famously, when you have a hammer, you tend to see nails everywhere you look. As president of the

Your Doctor's Knee-Jerk Reflex: How Not to Get Kicked

(2) Comments | Posted August 20, 2014 | 3:36 PM

We are, I trust, all but universally familiar with the knee jerk, or patellar, reflex. A doctor taps the patellar tendon with a rubber mallet, and our leg kicks forward in response.

The reaction is famously unthinking. In fact, it is literally so. What makes a reflex...

Sodium Studies, With a Grain of Salt

Another week, another roiling debate about nutrition. In the immortal words of Iago the parrot, I'm going to have a heart attack and die from that surprise.

Actually, heart attacks are directly germane to this topic; strokes even more so. The particular goal of guidelines addressing salt...

Congresswoman Rosa DeLauro recently introduced a bill for a national soda tax. Don't worry, this isn't about a soda tax, exactly.

Rabid Opposition to Ebola: Epidemiology Meets Hyperbole

(109) Comments | Posted August 4, 2014 | 1:12 PM

To be quite blunt about it, Ebola is a very scary disease. Among those infected, the mortality rate is, as is perhaps now widely known, an appallingly high 90 percent. That would seem a very good reason to keep our borders closed to this scourge- and the...

Processing Messages About Processed Food

(0) Comments | Posted August 4, 2014 | 11:28 AM

As you likely already know, unless you spent the past week under a rock, or preferably off the grid on a mid-summer idyll, the American Society of Nutrition issued what proved to be a very controversial position paper on processed foods. I know it was controversial because...

Massachusetts Chooses a Governor: Implications for Us All

(2) Comments | Posted July 28, 2014 | 9:07 AM

Fittingly, Beacon Hill is a neighborhood in Boston, and often used as a metonym for state government. Massachusetts has indeed served as a national beacon, most indelibly during the American Revolution -- but also of late, as the first state to implement a very close approximation to universal health coverage...

What to Do When Your Food Glows in the Dark

(0) Comments | Posted July 25, 2014 | 2:55 PM

What should a culture do with glow-in-the-dark food: (a) toss in a multivitamin for good measure; (b) call it part of a complete breakfast; (c) market it aggressively to children; (d) pretend it's a health food by making it low-fat, low-fructose, low-carb, trans fat free, or something...

No Taste for Truth?

This will be brief, blunt, and -- forgive me -- perhaps a bit brutal.

I find it incredible that a culture embracing "junk" not only as a food group, but one of its largest; and the junkiest of such junk as the preferential food...

Lifestyle Medicine and the Parable of the Tiny Parachute

A commentary was published last month on the blog site of the prestigious British Medical Journal telling us, in essence, that lifestyle medicine is ineffective. Specifically, it said that screening for chronic disease risk factors in the general population, and addressing them with lifestyle counseling in the...

Perils of Fire Fighting: Too Much Heat and Too Little Light

We live increasingly, it seems, in a world of too much heat, and too little light. Our failure to get the memo about climate change even as our goose is cooking is certainly an example. But in general, life seems inclined to imitate our fractious system of dysfunctional politics --...

A recent meta-analysis by an accomplished international team of researchers, published in a prestigious medical journal, shows that high intake of saturated fat is exactly as bad for health as a high intake of sugar and refined starch. The study also suggests there is something far worse.

Research Funding: When Is the Money Dirty?

Perhaps the most riveting moment in the documentary Fed Up is a moment of silence. Katie Couric peppers Dr. David Allison of the University of Alabama with a series of less-than-friendly questions about his industry-funded research related to nutrition and obesity. The usually-articulate Dr. Allison fumfers his way through...
