When we say “Happy New Year,” it is perhaps more plea or prayer than prediction. But there is still something of a forecast in it, or at a minimum- the projection of our will upon the canvass of the cosmos. Accordingly, the aspiration invites us to recall an aphorism. The best way to predict the future is to create it.


2019 Health Articles of Most Interest to Doctors

The Journal of the American Medical Association, or JAMA as it is known to most, is among the most widely read and cited, most influential, and most prestigious medical journals in the world. The journal just called “JAMA” is the flagship, but the other vessels in the fleet, such as JAMA Internal Medicine, and JAMA Pediatrics, along with 11 others representing diverse medical specialties- are all highly respected in their own right. 


The Massive, Expansive Importance of Diet

A recent commentary in JAMA asserts that research and messaging in the medical literature, and attendant media coverage, should emphasize the exposures that are most important and robustly linked to health outcomes, and not exaggerate matters of lesser importance. I agree entirely. 


Fools, Fanatics, and You

Many years ago, a Yale medical student of mine asked my advice about becoming Surgeon General. Admittedly, I was and remain a second-rate source of guidance on that topic, never having been Surgeon General. I hasten to note that a close personal friend of mine has been, as has a different, former student of mine. But I was left to offer the best counsel I could absent any first-hand experience.


The Case for Dietary Outrage

I was privileged to speak this past week at a Lifestyle Medicine Research Summit convened at the University of Pittsburgh Medical Center.  Along with the edification that came of listening to scholarly colleagues on various topics, I derived comfort from the table talk between sessions with expertly-informed friends who could share my grave concerns about the state of public and planetary health and the failure of our public policies to correspond.
