What You Should Eat, and Why You Should Eat It!

(1) Comments | Posted September 15, 2014 | 3:24 PM

I had not intended to write another column today, and to be candid about it -- I could use a break. But a piece about Dr. Jack Sprat and his identical twin brother (actually, it's the brothers Van Tulleken; "Sprat" is easier) crossed my desktop, I posted...

Salt in the Wound

(2) Comments | Posted September 12, 2014 | 3:09 PM

We eat too much salt, and so do our children. We can reduce our intake by eating less highly processed food, which is the source of nearly 80 percent of the sodium in our diets. Doing that, and eating more foods direct from nature would be good for...

HOW to Eat Well

In the midst of last week's rather copious flow of verbiage regarding what foods are good for us, I received a comment in my Twitter feed that we know WHAT; what we need to focus on is HOW. Frankly, I hope for that every day. Let's break it...

The Devil in The Disagreement: Lynching in Lieu of Listening

(2) Comments | Posted September 5, 2014 | 10:16 AM

The bad news -- for me, at least -- is that quite a few people seem to hate me. The worse news -- for us all, I think -- is that none of them knows me. They've just read something I wrote with which they disagree.

Diet Research, Stuck in the Stone Age

You cannot get a good answer to a lousy question.

The current diet study making headlines purportedly asked, and answered this question: Which is better for weight loss and improving cardiac risk, a low-fat or a low-carb diet? For starters, that is a truly lousy question, resurrected...

Loving Food That Loves Us Back, Extra Space at The Table

There is a geographical midpoint between living to eat, and eating to live. It's where health comes from the pursuit of pleasure, and pleasure comes from the pursuit of health. It's where you love the food you eat, and the food you eat loves you back -- by nurturing your...

Obesity on the Nile

Yes, there is obesity in Egypt; although the situation is far worse in other Middle Eastern countries that have undergone more dramatic cultural transitions in recent years. But that's not really my subject today anyway. Rather, I am invoking the well-known observation that the Nile...

Lifestyle Medicine: Have Hammer, See Nails, Seeking Spoon

(1) 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...

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

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 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.

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 --...
