David Katz, M.D. | Posted 07.26.2016 | Healthy Living
David Katz, M.D.

I know, you keep hearing conflicting reports about saturated fat and health outcomes. So do I. Most recently, just a few days ago, a colleague circula...

How to Feed Humans? Like a Species

David Katz, M.D. | Posted 07.12.2016 | Healthy Living
David Katz, M.D.

We are a species. Perhaps that’s a bit of a blow to our modern, so-over-biology, Homo sapien arrogance; but it’s true just the same. Like every ot...

Good Nutrition, In Circles On The Road To Nowhere

David Katz, M.D. | Posted 07.07.2016 | Healthy Living
David Katz, M.D.

Given the almost dizzying frequency of diet-related headlines, the one true revelation about nutrition is superficially the least likely: there is no ...

David Katz, M.D.

In all of biomedicine, spanning clinical care, medical research, and public health practice, we subscribe to the "precautionary principle." Basically,...

David Katz, M.D. | Posted 06.13.2016 | Healthy Living

The current (June 7, 2016) issue of the Journal of the American Medical Association devotes much of its rarefied real estate to the current state of t...

How Salt Shakes Out

David Katz, M.D. | Posted 06.02.2016 | Healthy Living
David Katz, M.D.

Risks of too little sodium are a valid concern only at levels massively below mean intake in the U.S., while the harms of excess are with us right now. The priority, obviously, is fixing what's broken. Kudos to the FDA. Their action on salt does not yet have traction in the real world -- but it does pertain to it.

The Fountain of Youth, Where No One Drinks

David Katz, M.D. | Posted 05.24.2016 | Healthy Living
David Katz, M.D.

We have been preoccupied with anti-aging perhaps since the very dawn of self-awareness, and the implications of mortality it unveiled. We have, ever since, tethered our fears to faith and fantasy, tangled our aspirations up in fable -- about fountains of youth in particular.

Diet Study Outcome? Work It; Flip It; Reverse It!

David Katz, M.D. | Posted 05.09.2016 | Healthy Living
David Katz, M.D.

Conclusions about diet study outcomes that are this precarious, that can be worked just a bit, and flipped -- are utterly useless. They are propaganda.

(Cultural) Implications of Biggest Losers' Unfortunate (re)Gains

David Katz, M.D. | Posted 05.02.2016 | Healthy Living
David Katz, M.D.

What the New York Times tells us today, no surprise to those of us who have worked directly with severely obese patients over the years, is that failure overtakes the show participants, too. Those of us in these trenches have known all along that though challenging, weight loss is rarely the rate-limiting problem.

Health Care: Of United, and Citizens

David Katz, M.D. | Posted 04.22.2016 | Healthy Living
David Katz, M.D.

As for the status quo, United is a business, and has the option of renouncing its high costs. The people paying for business as usual with their lives -- do not.

Chewing the (Dairy) Fat With Dr. Mehmet Oz

David Katz, M.D. | Posted 04.21.2016 | Healthy Living
David Katz, M.D.

Medicine and the media are in some ways like a celebrity marriage: of widespread, seemingly irresistible interest; and routinely on the brink of disaster. Neither union, nor the prevailing fascination with it, is apt to go away soon.

Musical Diets: You Can Dance if You Want to...

David Katz, M.D. | Posted 04.18.2016 | Healthy Living
David Katz, M.D.

We are no strangers to a dizzying array of distorted headlines about diet. But the last couple of weeks took it to a whole new level.

Diet, Deafness and the Drums of War

David Katz, M.D. | Posted 04.06.2016 | Healthy Living
David Katz, M.D.

A commentary just out in JAMA says many reasonable things about diet and health. The author notes that the overall low quality of the prevailing American diet is an anchor on life expectancy itself. Amen to that.

Vegetarianism: Nutrition Science Meets Media Nonsense

David Katz, M.D. | Posted 04.05.2016 | Healthy Living
David Katz, M.D.

The study does not report that vegetarianism increases the risk of heart disease, cancer, or any other bad outcome. Nothing of the sort. Not even close.

David Katz, M.D. | Posted 03.31.2016 | Healthy Living
David Katz, M.D.

Even for someone who spends as much time in the diet war trenches as I do, the barrage of the past week has been noteworthy for its intensity, and its implications -- both exceptionally hopeful, and dire.<

Selling Diets or Telling Truths

David Katz, M.D. | Posted 03.22.2016 | Healthy Living
David Katz, M.D.

We know what to eat; we simply keep refusing, across an expanse of squandered decades, to swallow it.

Truth About Saturated Fat

David Katz, M.D. | Posted 03.11.2016 | Healthy Living
David Katz, M.D.

The truth about saturated fat is not unsettled. What is unsettled is: Can we handle the truth?

Public Health and Citizens, Truly United

David Katz, M.D. | Posted 03.03.2016 | Healthy Living
David Katz, M.D.

Public health is all about doing the best we can for actual people, not a statistical and anonymous horde that exists nowhere outside of actuarial tables. That doesn't always align with the greatest profits for some large corporation. In fact, it almost never does, because of the time horizons involved.

Taking Public Health to the Moon

David Katz, M.D. | Posted 02.26.2016 | Healthy Living
David Katz, M.D.

By rallying to the mandate of the evidence-based, consensus-based fundamentals of health promoting, sustainable living and eating -- I believe we can accomplish something for public health and the human condition that is, quite simply -- out of this world

Fatness, Affluence, Adaptation and Hope

David Katz, M.D. | Posted 02.22.2016 | Healthy Living
David Katz, M.D.

We are a uniquely adaptable species. It has led us into trouble that imperils ourselves, and our planet alike. There are early indications of hope that it could lead us out as well.

Expert Dietary Guidance: Gasoline on a Fire?

David Katz, M.D. | Posted 02.04.2016 | Healthy Living
David Katz, M.D.

The flaws in genuinely expert advice about diet are analogous to: this hose vs. that hose; this water pressure vs. that. Spraying gasoline instead of water is a problem at a different level altogether.

The Randomized Trial Fantasy: How We Know What We Know

David Katz, M.D. | Posted 01.22.2016 | Healthy Living
David Katz, M.D.

I suppose I might be more expert in randomized controlled trials if I had ever had the actual opportunity to fetch a pail of water without one when my...

What's That Smell? That Which We Call 'Dietary Guidelines'...

David Katz, M.D.

Since the release last week of the current Dietary Guidelines for Americans, and in my case at least, a resulting bout of projectile vomiting, the nut...
