Diet More Vital than Ever: Diet ID, "Diet is a vital sign" logo encircled in a couple dozen red covid molecules

My first reaction to the COVID pandemic, actually just months but seemingly lifetimes ago, was not about social determinants of health. It was not about total harm minimization, vertical interdiction, or the context of other casualty counts. …Read More

Closeup of a golf ball on a fairway with "Mulligan" and the number 2 on it.

Tracking the pandemic trends- from around the U.S. and throughout the world– as best I can (no one can hope to keep up entirely with the constant deluge of data, drama, dogma, and diatribe)- I incline toward the hope that COVID may be offering us a Mulligan. …Read More

Silhouette of a human with light ray shining through their body juxtaposed on top of a Coronavirus molecule.

Is the pandemic over, or as the kids in the back seat might put it: are we there yet? If in Sweden, the answer is apparently: yes – albeit a very begrudging and tentative yes, encumbered by doubts, caveats, and aspersions from the camp prone to parlaying the valid arguments for lockdown into moral superiority. …Read More

Blackboard filled with mathematical equations.

The combination of initial forays back to the world, work, and notably schools; plus far more testing than we did at the start of the pandemic, produces one inevitable result: surges in case counts everywhere the population wasn’t uniformly exposed already. Is this bad, and if so- how bad? Is it in some way good? Or, is it something in between? …Read More

Doctor tests knee reflex on a patient.

You have no doubt heard the news that as universities reconvene students on campuses around the country, there are flares in COVID case counts. The inclination to return universities to lock down and disperse the students back home in response to this is predictable, and about as nuanced as a knee jerk reflex, give or take the knee. …Read More

Image of a House of (Playing) Cards with the top ones falling over onto the table.

An important new study in the New England Journal of Medicine had a primary objective of determining the nature of durability of antibody responses to SARS-CoV-2. In other words, the primary questions these researchers were asking were: do people show clear evidence of immunity after a COVID19 infection, and does that immunity last for months?Read More

Glass of water, half full...or half empty

Our disparate inclinations famously refract the same view into opposing perceptions: a glass half full, or half empty. The anxious passions engendered by the COVID19 pandemic have greatly amplified that proclivity. Rarely has the gulf between competing versions of optimism and pessimism, or other reciprocal ideologies, yawned so great. …Read More

Red circle with slash through it on top of a Coronavirus molecule. Diet ID logo on bottom right.

Roughly two weeks ago, the American Heart Association told the world that diet should be assessed routinely in clinical encounters, and that new tools were needed to make this possible. The new tools should be quick, elegant, efficient, reliable, accurate, user friendly and economical. They should interface seamlessly with electronic health records, fit without friction into clinical work flow. …Read More

Big red X on white background

We are a polarized society; I have not surprised you by saying so. We are a society with a low tolerance for nuance. We tend to favor: yes/no, right/wrong, good/evil, left/right kind of thinking. We are not the better for it, but it is what it is. …Read More

Black and white image of nurses in surgery garb folding face masks

I hope, my fellow Americans, that in spite of it all, you have a good holiday weekend. This is a hard time to “celebrate” America, both practically and in principle. Practically, the customary expressions of celebration are much obviated during a pandemic surge – by restrictions, regulations, cancellations, and lock-down extensions. …Read More

Ostrich facing left with its head buried in the sand

My colleagues, Maria Chikina and Wes Pegden, were entirely correct in their predictions of what happens when you flatten the epidemic curve without clear plans for a “phase 2” to follow. They were entirely, and obviously right- but I imagine they get no satisfaction from that, as I get none for having recognized that they were right. People in Texas, and Arizona, and Nevada; in Missouri, Alabama and Florida- are paying with their lives. …Read More

Surfer hitting a huge wave

I don’t think it is much of a stretch to say the United States has responded to the challenge of the COVID pandemic by doing nearly everything wrong. Federal guidance has been inconsistent and incoherent, and while waiting for evidence that grown-ups were running the country, sensible people with more regionalized authority lost critical time, and saw vital windows of opportunity slam shut. …Read More

Notecard with "It was the best of times... It was the worst of times." handwritten in cursive on it.

I was privileged yesterday morning to address the virtually assembled multitudes for the 2020 Harvard Lifestyle Medicine conference. Hundreds were gathered from throughout the US, and countries all over the world. As ever, the enthusiasm of this group ran high- albeit expressed on this occasion via texts on Zoom, rather than the smiles, hugs, high-fives, and back-pats of life as we knew it before COVID. …Read More

Busy city street, people seated at outdoor restaurant tables.

For much of the world, the past three months had a clear goal: “lockdown and avoid Covid-19 exposure.” But, in recent weeks, a restless public had already been transitioning haphazardly out of this stage, ranging from demands for continued isolation to massive pool parties and “liberate my state” rallies. With the addition of large gatherings and protests of the past week, confusion and anxiety have even further grown. …Read More

Head shots of 12 people of various ethnicities

There is a trait other than skin pigment that we humans do seem to share all but universally: a rather short attention span. A veritable “moment” before the COVID19 pandemic began rewriting the modern history of public health practice, fixating our attention, and propagating our miscellaneous anxieties, we had declared another epidemic here in the United States a national emergency, after considerable debate and dithering. …Read More

Ficticious angry brown 2-headed fanged tiger-like animal with a split devil-like tail and evil eyes.

One could be forgiven for thinking that however bad it is to be in the middle of one pandemic, it would be worse to be in the middle of two at the same time. In fact, though, we are very much in the middle of two- and at least through one pertinent lens, two pandemics are better than one. …Read More

Three hands holding full glass beer steins and clinking them together to toast.

My fellow Americans- and to be ecumenical about it, my fellow humans- I have two questions for you. Do you have at least half a wit? And, do you have at least half a heart?

If the answers are yes- you have at least half of each- then I contend it’s time to come out of opposing corners and meet in the middle of the COVID infodemic. Enough of the polarizing nonsense that passes for COVID policy debate in this country. Seriously: enough.

Light switch on gray wall. Switch is "on."

We must, to some extent, be something like flotsam in the currents of culture, debris on the winds of the Zeitgeist; a bit helpless against the buffeting of “now,” in all its particulars.

Perhaps it is the Internet and social media; perhaps the constant immediacy of news cycles. Whatever the reasons intrinsic to “now,” they exert some dominion over our thinking, and seemingly the dictates of now call for: pretty dumb. …Read More

COVID, Hope, and Consternation: screenshot of the "US Senate Committee on Homeland Security and Governmental Affairs" website page with the announcement and link to the "Roundtable - COVID-19: How New Information Should Drive Policy" hearing video.

I have had abundant opportunity to share my various reflections on the COVID19 crisis. This week, I had the chance to do so directly before the Homeland Security Committee of the United States Senate, and at full length and leisure in a podcast interview with my friend, Rich Roll. What’s left?

Hope, and consternation. …Read More

White Paper: Updated estimates of comorbidities associated with risk for COVID-19 complications based on US data.


We updated previous estimates (wwwnc.cdc.gov/eid/article/26/8/20-0679_article) of adults with any underlying condition increasing risk of complications from COVID-19 using recent US hospitalization data instead of mortality data from China. This substitutes obesity for cancer in the definition and increased the percentage of adults reporting more than 1 condition to 56.0% (95% CI 55.7-56.4). …Read more

Thomas L. Friedman of The New York Times: With each passing day it becomes more obvious how unlucky we are that one of the worst crises in American history coincides with Donald Trump’s presidency. To get out of this crisis with the least loss of life and least damage to our economy, we need a president who can steer a science-based, nonpartisan debate through the hellish ethical, economic and environmental trade-offs we have to make. …Read more

Sunset at the pyramids.

We are, no doubt, all comparably eager to consign this blighted interval- of coronavirus contagion, social upheaval, recrimination and fear – to the history books.

Sabertoothed tiger looking towards the left side of the camera and roaring ferociusly.

Believe it or not, now- with the acute threat of COVID19 constraining our activities and propagating our anxieties- there may have never been a better time to address and improve the chronic state of our health, both as a population, and as individuals.

America Responds to Pandemic Coronavirus! Image of Dr. Katz with a facemask and a "Make America Safe Again" baseball cap, in front of the US flag

Much has been made of my early contention that the coronavirus could hurt and kill people more than one way, and that we needed to do our best to interdict them all. I called the approach – that would keep those vulnerable to severe infection and the direct harms of the virus away from it, while allowing those more prone to harm through a degradation of services, goods, livelihoods, supply chains and the social determinants of health back to the world early – vertical interdiction. …Read more

Huge wave of blue water and seafoam crashes on a brown sand and pepple-filled beach

There is no debate, and never was among serious people, about the need to keep those at high risk for severe coronavirus infection and this very nasty germ – SARS-CoV-2- apart. There is only debate about how. Any suggestion to the contrary is misunderstanding, willful or inadvertent, or the replacement of actual ideas with caricatures of them. …Read more

Coronavirus, Casualties, and Context: Do We Dare Discuss Other Numbers? Headshots of about 500 people all adjacent to each other.

Ordinarily, I work to draw attention away from the crude, bland, anonymizing statistics of public health to the faces they veil, the human stories they obscure.

But as the coronavirus pandemic becomes an ever more proximal menace, affecting more people we all know and love- I see a need to go the other way, and highlight the use and misuse, the lessons and liabilities of numbers, in and out of context. …Read more

Man in heavy coat and face mask walks towards the right of the camera, in front of the Basilica in Rome.

Of the slightly more than 30,000 total, global deaths from coronavirus to date, a third of them all have been in Italy. That sad distinction means Italy is the source of our best potential insights about COVID19 and the risk of severe infection and death.

Colleagues reached me this morning with this March 26 compilation of coronavirus data from the Italian health ministry, when the mortality toll was at around 7000: …Read more

Two medical workers in full protective gear, with blue gowns, blue gloves, masks and hair covers, point a swab towards the driver side window of a car to test for Coronavirus.

Only in a world of ideologues and demagogues, of propagandists and Internet trolls, are our options limited to: “send everyone back to the world by some arbitrary date, and never mind the body count” versus “everybody’s grandparents in coronavirus lockdown until many of them die of other causes before ever again hugging their grandchildren.” Indefinite lockdown and indiscriminate largess are two variants on a common theme of heartless, thoughtless public health carnage. Of course there is another way. …Read more

I am just back from being tested for COVID19- very efficiently and professionally, I might add- at Griffin Hospital in Derby, CT. I can’t commend my Griffin colleagues enough for how beautifully they organized. Below are images of the test facility, and the print guidance I received. That said, I won’t have my test results for 3 to 5 days, which is far too long- not just for me, but for the system that needs those data to understand and best address the pattern of the epidemic. …Read more

2 charts showing age of patients vs days days to COVID infection

Birdseye view of a man walking down a street wearing a black coat, sneakers, headphones, a protective face mask and hospital gloves looking at his cell phone.

Thomas L. Friedman of The New York Times: One of the best ideas I have come across was offered by Dr. David L. Katz, the founding director of Yale University’s C.D.C.-funded Yale-Griffin Prevention Research Center and an expert in public health and preventive medicine. Katz wrote an Op-Ed in The Times on Friday that caught my eye. He argued that we have three goals right now: saving as many lives as we can, making sure that our medical system does not get overwhelmed — but also making sure that in the process of achieving the first two goals we don’t destroy our economy, and as a result of that, even more lives. …Read more

2 medics load a patient on a gurney into an ambulance.

The New York Times: If we were to focus on the especially vulnerable, there would be resources to keep them at home, provide them with needed services and coronavirus testing, and direct our medical system to their early care. I would favor proactive rather than reactive testing in this group, and early use of the most promising anti-viral drugs. This cannot be done under current policies, as we spread our relatively few test kits across the expanse of a whole population, made all the more anxious because society has shut down. …read more

Map of the world showing where the highest concentrations of Coronavirus are as of 3/13/20.

COVID-19 is not an even-handed scourge. The risk of severe coronavirus infection, and death, are highly concentrated among those over age 80, to a lesser extent among those over 70, and in particular where baseline health is already poor. To maximize the efficiency of our harm reduction efforts- containment, prevention- they should be targeted accordingly. …read more

White hospital face mask on a table.

No one will know for sure the best responses to the COVID-19 pandemic until after it’s all over, and we look back and second guess ourselves.

Table with Coronavirus statistics

How lethal is the coronavirus, compared to, say, the flu? The only way to know a rate- any rate- is to know both the numerator (i.e., those who suffer the outcome), and the denominator (i.e., the population at risk/exposed). …read more

Coronavirus statistics as of 3/8/20: 107,491 cases and 3,652 deaths

There’s no way to watch the COVID-19 drama unfold and not be concerned/anxious (as if we needed another reason for anxiety these days!). My primary point early on- here – was that we exaggerate the ‘new and shiny’ risk relative to more familiar perils. That remains true of COVID-19 almost no matter how bad it gets. …read more

Asteroid hitting the Earth's atmosphere and bursting into flames

The ultimate questions- will I get this disease, and will it kill me if I do?– can be broken into component parts. The first is, what is my risk of exposure?

Poor overall diet quality is the single leading cause of premature death in the United States today, causing an estimated 500,000 or so deaths each year.
