National Nutrition Policy, Imperiled By Bullies

David Katz, M.D. | Posted 10.24.2015 | Healthy Living
David Katz, M.D.

The nation's official position for the next five years on diet for health is on the line, imperiled by bullies. I am speaking out simply because we don't know how many others, encountering the same forces, have decided doing so is not worth the abuse. I am speaking out because: it is.

Hormone Replacement's "AHAH" Moment

David Katz, M.D. | Posted 10.24.2015 | Healthy Living
David Katz, M.D.

It has long been clear that effects of hormone replacement are best when treatment begins early rather than late after menopause. The data showed such distinctions, but they too were obscured by a rush to summary judgment.

David Katz, M.D.

Jane Brody published a very sensible reality check about diet in yesterday's New York Times. That it proved sensible was all but inevitable, as her co...

Poetry, Prose and the Presidency

David Katz, M.D. | Posted 10.14.2015 | Healthy Living
David Katz, M.D.

The power of the Presidency is the power of persuasion, and a strength born of, and only of, unity of purpose. The President is Persuader-in-Chief. The only true source of power is consensus.

Stunning Health Benefits of Cotton Candy Proposed

David Katz, M.D. | Posted 10.11.2015 | Healthy Living
David Katz, M.D.

The controversy and clamor attached to the report of the 2015 Dietary Guidelines Advisory Committee would seem to suggest that something that radical had been proposed. But that's not quite the case.

Milking Dietary Discord: Who Holds the Bucket?

David Katz, M.D. | Posted 10.07.2015 | Healthy Living
David Katz, M.D.

For now, the cow can be dietary guidelines. In fact, the placement of cows, and milk for that matter, in dietary guidance is at the heart of current discord- and we are all well advised to wonder: who holds the bucket?

Speaking Freely of Guns

David Katz, M.D. | Posted 10.04.2015 | Politics
David Katz, M.D.

For now, we have an endless litany of tragedies to which we react with collective pathos and impotence, knowing for certain that we await the next. We have a bizarre double-standard, in which the First Amendment is spared the tortured literalism imposed upon the Second by those with ulterior motives.

Sugar and Saturated Fat: Feeding the Parasites of Science

David Katz, M.D. | Posted 10.01.2015 | Healthy Living
David Katz, M.D.

But between us and that opportunity are the parasites of science who have no apparent interest in the weight of evidence, and instead feed selectively on studies depending on whether they endorse the opinion they've already decided is true.

An Open Letter to the BMJ Regarding US Dietary Guidance

David Katz, M.D. | Posted 09.25.2015 | Healthy Living
David Katz, M.D.

This commentary is not authoritative. It is not a counterweight. It is, at best, a paperweight. I am sorry to say its prominent placement on your editor's desk redounds to your discredit.

Raising Safer Daughters; Raising Better Sons

David Katz, M.D. | Posted 09.24.2015 | Healthy Living
David Katz, M.D.

There may well be duties in these data for university officials. But there are duties in them for parents, too. The victims are, inescapably, our daughters. The report is shockingly silent on the fact that the perpetrators are, inevitably, our sons.

Doctors, Death and Dignity: The Semantics of 'Suicide'

David Katz, M.D. | Posted 09.18.2015 | Healthy Living
David Katz, M.D.

Death is the enemy, and it is not. Death is simple and inevitable, and inexplicably complicated.

Breast Cancer Screening: Of Chances and Choices

A sardonic insight by Bertrand Russell deftly, if disturbingly, conveys much of what is wrong in the realm of modern health promotion, particularly wh...

On and Beyond the Ethics of (Animals) Eating Animals

David Katz, M.D. | Posted 09.10.2015 | Healthy Living
David Katz, M.D.

For those committed to meat consumption, eating what they kill may offer various advantages over eating what they find sealed in cellophane. But it is a niche admonition at best, impertinent to the masses of us.

Dietary Fat and the Human Brain: Redefining Food for Thought

David Katz, M.D. | Posted 09.04.2015 | Healthy Living
David Katz, M.D.

As our kids return to school, it's a perfect opportunity to reflect on the human brain doing what it does uniquely well in all the known animal kingdom: learn. At the very foundation of that remarkable Homo sapien aptitude lies the structural integrity of the brain itself, which proves to be highly dependent on a native, salutary balance of dietary fats.

The Smart, Scary Thing About Dummies

David Katz, M.D. | Posted 08.16.2015 | Entertainment
David Katz, M.D.

Those dummies may be hard to abide because they confront us with ourselves. Some of us may prefer to avert our eyes because of what lies within. The dummies are too much like us. Like us, they are but a gesture apart from the darkness.
