I was greatly privileged this past weekend to deliver a keynote address at the American Academy of Anti-Aging Medicine (A4M) World Congress in Hollywood, Florida. I have spoken before at the Academy's conference in Las Vegas, and will have the opportunity to do so at their

Invincible Food, Vulnerable Father and Son

(0) Comments | Posted May 18, 2016 | 2:22 PM

One of the regional supermarket chains in my part of the world, in fact the very one my family shops most often, routinely markets pizza in their TV commercials. The very point of TV commercials for a retail supermarket is to get people into the store, and this strategy must...

KIND and Healthy Food Label Update by the FDA

(0) Comments | Posted May 13, 2016 | 11:52 AM

Just over a year ago, KIND, a company I have long admired, with products my family has long enjoyed, received a reprimand of sorts from the FDA. The company was informed in a warning letter that their use of the word "healthy" on some of their product packaging...

Mechanics of Metabolism Maintenance: Cars, Keys, and Karelia

(0) Comments | Posted May 10, 2016 | 4:35 PM

If you keep up at all with matters of diet and health, you have no doubt noticed the thriving cottage industry in revisionist dietary history, from big fat lies, to big fat surprises, to sugar conspiracies. A consideration of cars, Keys, and Karelia will lend some much needed perspective.

Diet Study Outcome? Work It; Flip It; Reverse It!

(0) Comments | Posted May 9, 2016 | 10:04 AM

I confess here, as I have done to my kids, that I have never fully understood what Missy Elliott was talking about in her song, Work It. I get the general impression it's better off that way.

That notwithstanding, and renouncing any links to salacious innuendo, I am obligated to...

A feature article in today's New York Times chronicles the unfortunate fate of participants in The Biggest Loser after the spotlights dim, the TV cameras stop speeding, and some time goes by. They regain the weight. Some of it, most of it, all of it, or even...

For Evil to Prevail

I can't tell if Edmund Burke and I would agree or disagree about most things; the politics and issues of his day were so different from our own, I'm not sure what kind of political animal he would be branded today. In his day, he was labeled...

Nutrient Supplements in the Land of the Law of Unintended Consequences

(1) Comments | Posted April 28, 2016 | 3:50 PM

In principle, the law that constrains the marketing of nutrient supplements in the U.S. is "DSHEA," or, the Dietary Supplement Health And Education Act (of 1994). In practice, the law of unintended consequences may exert an even greater influence.

I write this in the immediate aftermath of...

Fixing Epidemic Obesity? We Have Never Tried...

(3) Comments | Posted April 26, 2016 | 4:06 PM

This column isn't about guns or gun control. It's about food, and food for thought, entirely out of control. It's about epidemic obesity, and what passes for deep thinking on the topic. With that proviso out of the way, let's get back to guns.

Our gun control arguments must be...

Health Care: Of United, and Citizens

The disturbing news item of the past week -- assuming we discount the increasingly routine reports of terrorist bombings, boats packed with desperate migrants capsizing, the global temperature relentlessly rising, and Russian military bombast -- is that the nation's largest health insurer, United Health Care, is withdrawing...

Chewing the (Dairy) Fat With Dr. Mehmet Oz

I was delighted to join my friend Dr. Oz today to tape a segment for his show about the recent studies of dairy, weight, and diabetes. I believe the exchange Mehmet and I had blenderized our perspectives well, and should prove genuinely informative -- albeit brief, punchy, and,...

We are no strangers to a dizzying array of distorted headlines about diet. But the last couple of weeks took it to a whole new level.

I found myself reflecting on, then laughing at, the image of a world that takes seriously the idea that what we know about the...

Vegetables, Vegetable Oils and Dairy Fat? Please Don't Eat the Headlines!

One of the particular fringe benefits of what I do is that my interactions almost every week include leading experts in my field from all around the world. Sometimes that's face to face at a conference that convenes a few of us, or on rare and special occasions, assembles

Diet, Deafness and the Drums of War

(1) Comments | Posted April 6, 2016 | 12:50 PM

A commentary just out in JAMA says many reasonable things about diet and health. The author notes that the overall low quality of the prevailing American diet is an anchor on life expectancy itself. Amen to that. No, multicolored marshmallows are NOT part of a (sane) complete...

Vegetarianism: Nutrition Science Meets Media Nonsense

We get hyberbolic headlines about nutrition studies almost every week; it's how we roll. We can come back to the reasons why we roll that way, and who profits from it, some other time.

For now, it's enough to note that the global spate of headlines saying things like "

How Diets Divide Us

Even for someone who spends as much time in the diet war trenches as I do, the barrage of the past week has been noteworthy for its intensity, and its implications -- both exceptionally hopeful, and dire.

The hope, seen by the ubiquitous glow of computer screens if not the...

The Health Care System: What's in a Name?

(0) Comments | Posted March 29, 2016 | 10:33 AM

The trail that led me to a career in health promotion is relatively more or less selfish, depending on where we begin it.

The rather more selfish version began at age 13. On little more than a whim, I tried out for the junior high school wrestling team, which, not...

What If Exercise Were More Like Healthy Eating?

(0) Comments | Posted March 21, 2016 | 6:22 PM

If exercise were more like healthy eating -- none of us would be doing it.

We would, instead, be perennially parked on the couch, on inevitably flabby backsides, watching experts argue over which is "right" -- hiking or biking? Walking or swimming? Skiing or skating? And so on.
