Putting Saturated Fat on Trial

As I listen to the seemingly ceaseless, virtual shouting about diet and health these days, much of it self-serving, and little of it genuinely informative or helpful, I am reminded of my now five-year-old wish that we might better separate church and plate. How did what should be a topic based on the aggregation of scientific evidence, time honored good sense, expert consensus, and personal preference- take on the strident passions and dangerous fervor of a Holy War?


Partial Eclipse of the Heart

One of my daughters made the trip to North Carolina to see the eclipse in the “totality” zone. I’m a little jealous- but mostly just happy that she had the chance to do it.


Diet and Health: Puzzling Past Paradox to PURE Understanding

Imagine a new study, published, one presumes in Road & Track, or Car and Driver, purporting to show that square wheels outperform round wheels. Imagine the attendant headlines: “Everything Thought Known About Wheels Proves Wrong!” and “Wheel Guidelines Need Radical Change!”


Diet: Choosing How to Be Wrong

I am quite confident about the fundamental truths of diet for good health. I am quite confident because they are predicated on a massive aggregation of evidence of every description, spanning methods, populations, and decades. I am quite confident because I share these convictions with a veritable who’s who of leading experts, with predilections from vegan to Paleo, from all around the globe.


Menopause, Hormone Replacement, and Mortality: A Research Reality Check

Perhaps you are in a hurry. If so, here’s the bottom line at the top: it turns out women can use hormone replacement to manage symptoms at menopause with, at worst, no adverse, long-term effect on the risk of mortality or any major chronic disease.


Science and Sense in a Post-Truth World: How Do We Know?

In my work and my world, I am dealing routinely with whiplash-inducing headlines about health, and nutrition in particular (“no, wait, fruits and vegetables are bad for us this week!”) that raise questions about science, sense, and knowledge. When whatever we think we know, however reliably we think we know it, is called into question so routinely, it begs the question: how do we know? 


Strokes of Unkind Fate

A crisis, it has been said, is a dangerous opportunity. One presumes that crises vary with regard to both. Some, no doubt, are more dangerous while providing less opportunity. 


Diet, as a Matter of Taste

Some years ago, I found myself at a corporate meeting of Kraft. I don’t recall exactly how or why I wound up on that guest list, but I recall that the meeting was rather surreal.


Flu Us Twice?

All indications are that this is shaping up to be a fairly nasty flu season. As fate would have it, that troubling news coincides with the 100-year anniversary of the mother of all nasty flu seasons, and perhaps the single greatest global calamity in the history of our species: the 1918 flu pandemic. 


DACA, CHIP, and Diet: Should Kids Be the Pawns of Our Politics?

The prospects for young people to be vital and safe, to develop and thrive, and the promise of their lives when they do, surely cannot be partisan concerns. They are human concerns. They are a crusade for every loving parent and grandparent; aunt and uncle; godparent and guardian; and maybe every adult who has ever known a kid, or been one. They are a shared crusade for us all.
