Of Salt, Saltation and Salience: The Case for Fixing What's Broken

(5) Comments | Posted April 17, 2014 | 3:39 PM

We have long had abundant reason to believe that most of us living in the modern world consume too much sodium and would benefit from consuming less. But whether the topic is salt, or saturated fat, or calories, or even the health effects of consuming vegetables and fruits...

What I Would Do If My Foot Caught Fire

(1) Comments | Posted April 14, 2014 | 7:51 PM

I know it seems like the obvious choice, but I would not run a randomized clinical trial.

I have recently lamented the pernicious influence, within my domain of public health practice, of hyperbolic headlines proclaiming "this," followed unfailingly by equally and oppositely hyperbolic headlines reactively proclaiming "that." But...

The Gravity of Misinformation

(1) Comments | Posted April 11, 2014 | 1:36 PM

The recent concentration of misleading media hooey about health has been excruciating, but the problem is perennial. I trust I needn't make the case that you are under constant assault by distorted, contorted, titillating, and insipid headlines. This is certainly true in my domain of health and medicine; it may...

Severe Obesity? Let 'Em Eat Kale!

The tale of aristocratic indifference on the part of Marie Antoinette, Queen of France at the time of the French Revolution, wife of Louis XVI, is, we now know, likely apocryphal. Still, like many historical distortions, this one reverberates through modern culture just the same, and harbors meaning as archetype,...

iDietology: Why I'm Fed Up, and You Should Be, Too

(0) Comments | Posted April 7, 2014 | 4:06 PM

iDietology is where diet meets ideology. I know, because I just made up the word. It's rather toxic food for thought, there is way too much of it around, and I advise you to sustain yourself on better fare.

As you might expect, I have a...

I generally appreciate the work and writing of Mark Bittman. But on one prior occasion, I was obligated to highlight his erroneous interpretation of an epidemiologic study about sugar, obesity, and diabetes. Mr. Bittman responded cordially and graciously when I pointed out his error, and more generally, his...

Weight-Loss Resistance and Choices

(2) Comments | Posted March 25, 2014 | 1:38 PM

Weight is not a behavior, and weight is not a choice. Nobody wakes up and decides what to weigh today. In an age when healthy and unhealthy behaviors are increasingly subject to incentives and disincentives, respectively, this is all too easily forgotten.

Of course, weight is largely the byproduct of...

Diet and Health: There, There and Getting There

(3) Comments | Posted March 24, 2014 | 11:12 AM

I am about to make the case that with regard to the profound influence of dietary pattern on health, we need to know both where there is, and have practical strategies to get there from here if we are to benefit. I believe our knowledge is more than...

The New Dietary Fat Study: What You Will Hear and What It Really Means

(10) Comments | Posted March 18, 2014 | 4:20 PM

No, it is not suddenly good to eat more saturated fat -- and the new study grabbing headlines showed no such thing.

The new study, a meta-analysis (meaning a pooling of previously published studies, not new research) in the Annals of Internal Medicine, shows...

Bullet Holes in the Bill of Rights

This will be brief: I find it incredible, and deeply disheartening, that the confirmation of our next U.S. Surgeon General may come undone because Dr. Vivek Murthy has expressed his support for widely favored gun control measures, such as an assault weapons ban.

Now, before you...

Drowning in Calories

(0) Comments | Posted March 13, 2014 | 6:53 PM

Among the more contentious issues regarding health and weight control -- perhaps surprisingly, contentious among professionals and the general public alike- is the role of personal responsibility. Unfortunately, this readily devolves into discord, because the cultural tendency of our time is denigrate those with whom we...

Meat-Eating Humans: Mightier Than Lions, Feebler than Ants

(10) Comments | Posted March 11, 2014 | 4:07 PM

I know some of you prefer the punch line right up front, so for that camp, here you go: A population of some 7 billion Homo sapiens simply cannot eat much meat. Period.

In my world, the debate about meat-eating often devolves to competing views about nutrients, advanced...

Better Food Labels: Have We Hit the Nail on the Head?

(3) Comments | Posted March 7, 2014 | 12:00 PM

Improving food labels, as planned by the USFDA and much in the news over the past week or so, is a welcome thing. But I do think we have cause to wonder if all the fanfare and media hype are really warranted. When all is said and done,...

Childhood Obesity: Have We Turned the Tide?

Mastery, Masturbation and Members of an Angry Mob

(1) Comments | Posted February 26, 2014 | 2:20 PM

Selectively seeking, finding, and/or citing those sources that affirm what we already believe and wish to be true is not scholarship. It does not qualify as research. It does not even meet standards for homework of any respectable pedigree. It is the academic analogue to masturbation: self-gratification,...

What's Wrong With Us? Three Names, One Place, a Company and a Substance

I loved the movie Four Weddings and a Funeral. Those five events and the people caught up in them were artfully used to convey a spectrum of human emotion, to evoke a panoply of empathies, and to do what good art does: imitate life and help us understand...

Can We Unmuddle Mammography?

A new study of mammography, showing lack of survival benefit, has once again muddied these waters and muddled the relevant messaging. The study, generating considerable controversy, as has much prior research on the topic, looked at breast cancer mortality over a 25 year period in nearly...
