DNA, Dunkin' and Dingbats

In the heady days of the genomic dawn -- not all that long ago, really -- we dreamed of dominating our DNA. Our hopes -- born in retrospect of characteristic Homo sapien hubris -- ran to wrestling with wayward ribonucleic acids; tinkering with our telomeres; and in all...

The Flu Vaccine: of Flubbing and Drubbing

(76) Comments | Posted December 5, 2014 | 11:26 AM

This year's flu vaccine, as you likely know, is taking a drubbing. The contention is that CDC flubbed, and didn't get quite the right flu strains in the mix. That is apparently true, although more the "fault" of the influenza virus and its natively wily ways,...

The Obesity Fix

(0) Comments | Posted December 3, 2014 | 2:57 PM

McKinsey & Company recently issued a report on effective means of fighting hyper-endemic obesity in the modern world. Among other things, they concluded that "implementing an obesity-abatement program on the required scale will not be easy." I presume that is intended to be somber, but the magnitude of...

Demystifying Calories: Already There and Miles to Go

(1) Comments | Posted December 2, 2014 | 1:32 PM

There are three good reasons to write about calories right now. First, the FDA just took action to regulate calorie labeling in chain restaurants. Second, colleagues just published yet another peer-reviewed paper probing the mysterious depths of the enigmatic calories.

Third, and most important, if your Thanksgiving was anything...

Health for the Holidays? Have Fun!

With this singular season of lofty ideals, crass commercialism, family gatherings, varying religious significance, aeronautical ungulates, indulgent torpor and culinary debauchery- euphemistically known as "the holidays" -- upon us, where should health figure in it?

At the front of the line, I say. Have a good time!

Public Health as Political Prisoner

If a foreign government took the United States Surgeon General hostage, I'm confident we'd be pretty upset. I think we would be working on reprisals, and maybe even prepping a SEAL team.

I don't know if it's better or worse that we need no help from a foreign power...

Best Diet? Look Beyond the Beauty Pageant

Can we say what diet is best? Well, not on the Today show.

A study published this week in Circulation: Cardiovascular Quality and Outcomes purportedly compared an array of "popular" diets and found that -- despite a whole lot of marketing claims and clamor -- none...

Whole Grains and Half-Witted Notions

I was delighted to speak yesterday at the sold-out Whole Grains Council conference in Boston. I was also delighted to find myself in the company of a veritable who's who of dietary sense and science. Missing from the audience were ideologues and iconoclasts. Present were those people whose careers are...

Remember when we were trying not to panic about Ebola? Seems like that was only yesterday. Oh wait -- it was only yesterday. But it already seems as if we are trying to remember that we were trying not to panic.

I suspect, and hope, that for readers here my views on nutrition are pretty well known. I contend that we do, indeed, know the basic theme of optimal eating for health -- just as surely as we know that no one variation on that...

Softer Care for Harder Cases, of Ebola and Everything Else

(5) Comments | Posted October 16, 2014 | 11:03 PM

The evolving Ebola outbreak is very disconcerting, to say the least. The situation in West Africa is, obviously, truly dire -- with projections of the toll escalating from terrible to calamitous day by day. A dreadful, transmissible disease in a part of the world where access to...

A Taste for Stealth

(0) Comments | Posted October 15, 2014 | 7:46 PM

Stealth nutrition can work for you or against you. Unfortunately, it has been used against you by the food industry for years.

First, we need a definition. Stealth, of course, refers to actions that are secretive or concealed. The term has been applied to health -- by yours truly,...
