Why Notre Dame Burned, and What it Has to Do with Your Health

Notre Dame Cathedral ignited, so far as we know, because accidents happen at construction (and reconstruction) sites. But it burned so ferociously because of a cluttered attic of flammable materials referred to as “the forest.”


What is Your Diet ID?

Food is medicine- the best there is. But “medicine” is generally used to treat or manage something, and famously, we tend only to manage effectively what we measure. Thus, mean logic dictates the corollary: we should measure what matters. Yet, we almost never measure the one health variable that matters most. More on that shortly.


Food is Medicine

Food is medicine, the best there is- assuming we get it right. The idea is far from new; Hippocrates famously espoused it. The idea is not new in the realm of research, either, including the variety of research generally most revered (at times for better, at times for worse): the randomized controlled trial. We have randomized trials to show that high blood pressure, pre-diabetes, dyslipidemia, and coronary artery disease – just to name a few- can be treated with diet (and, at times, other lifestyle interventions) as effectively as with state-of-the-art pharmacotherapy.


Eggs, Oxygen and the Perennially Breathless State of Our Nutritional Nincompoopery

Are eggs good or bad for us now? Yes. A recent meta-analysis, widely covered by media ever hungry for just such dietary provocations, reported that the more eggs people ate over time, the more prone they were to heart disease. This, inevitably, has been juxtaposed with the advice in the 2015 Dietary Guidelines to abandon a specific focus on dietary cholesterol- and unleashed the predictable round of breathless expostulations about the deplorable state of nutritional science and understanding.


Is The United States Shrinking? The View from Sharjah

As I write this, I am just back - last night - from Sharjah, where I spoke at a conference. With all due respect to my most gracious hosts, before receiving the invitation to speak in Sharjah, I had never even heard of it. This is despite the fact that I have been to the United Arab Emirates (of which Sharjah is one) before, for a World Health Organization project in Abu Dhabi some years ago. I have been to neighboring Qatar for a public health conference as well. Even so, I had not heard of Sharjah- which now occupies a special place in my memory, and a warm spot in my heart.
