To Be, Or Not To Be, Fatter? Of Science, Sense, and Squirrels

Science is, principally, all about methods for generating good and reliable answers. Sense, however, is required to ask good questions.

Heart Disease is Not Hypothetical

A commentary published in the British Journal of Sports Medicine contends that saturated fat is uninvolved in coronary artery disease. Before you get too excited: the commentary is comprised only of theory and opinion, none of it new, all of it expressed by these same authors before. The cited support involves no new research either.

Prostate Screening Gets Personal

I can guess what some of you must be thinking: what do you mean, gets personal? Wasn’t prostate screening already quite personal? What, after all, could be more personal than an examining finger inserted into your…well, you know where the prostate is.

Why Everything We Know About Salt May Not Be Wrong

A New York Times column offered us this provocative headline: Why Everything We Know About Salt May Be Wrong. Presumably that means- it may be right, too. Hence, my counter-headline.

Obesity, and the Limits of Imagination

The issue (January 16, 2018) of the Journal of the American Medical Association (JAMA) was devoted to the topic of obesity. On the one hand, we may be thankful this intractable public health scourge is receiving the high level attention it deserves. On the other, we may lament the need for such attention in 2018, so many years and decades into a problem we created, and which we have known all along how to address and prevent if ever we mustered the will.

Ode to Olive Oil

As lovingly and lavishly revealed in her own photo-essay on the topic, my wife and I are recently back from co-hosting an Oldways sponsored culinary travel adventure through Sicily. We ate, we drank, we toured, we made friends, we saw the dual beauties of nature and ancient civilization, and then- inevitably- we ate and drank some more!

The Roots of Pain

I was privileged this week to speak at the annual meeting of the American Pain Society. It was especially gratifying to address a group of clinicians and researchers committed to one of the most laudable causes in all of health care: the relief of pain, and the alleviation of human suffering. Maybe they lose by a nose to those saving the rain forests, but it’s a close call.

Muddled Guidance at Menopause

By definition, a muddle is an untidy or disorganized collection. The verb denotes propagating confusion by bringing some topic into just such a state. I regret to say that, accordingly, the United States Preventive Services Task Force (USPSTF) is poised to muddle the management of symptoms, and chronic disease risk at menopause.

Misremembering What Makes Us Fat

There is a particular irony in marking the occasion of Memorial Day by misremembering history. TIME Magazine’s cover story about why diets fail so many of us, and why so many of us are fat, is thus almost as ironic as it is interesting. The article apparently misremembers, and all but fails to mention, the most fundamental, influential, and flagrant of explanations for our obesity problem. But we’ll come back to that.

Do We Dare to Eat Lectins?

In The Love Song of J. Alfred Prufrock, T.S. Eliot’s protagonist asks, chewing on mortality and the pangs of senescence, if he dares to eat a peach. We can all thank Dr. Steven Gundry for upping the ante, and asking if any of us dares to eat chickpeas or eggplant; apples or oats; beans or lentils; or for that matter, almost any fruit, many vegetables, and most beans, legumes, grains, and certain nuts. His answer is: no. His reason is: lectins.
