David Katz, M.D. | Posted 09.23.2016 | Healthy Living
David Katz, M.D.

The big medical news of this past week was a seminal study of prostate cancer, suggesting that when it is diagnosed, we men have options―including t...

Sugarcoating Diet Science: Seeking Simple Truth, Past The Frosting

Butter, Beef, And The Yale Daily News

David Katz, M.D. | Posted 09.15.2016 | Healthy Living
David Katz, M.D.

I keep turning up in the Yale Daily News lately. I wouldn’t necessarily know about it, because I don’t read the Yale Daily News- but well-intenti...

Humanity’s Fishy Origins

David Katz, M.D. | Posted 09.08.2016 | Healthy Living
David Katz, M.D.

I am just back from a sequence of speaking engagements at scientific conferences in and around Cape Town, South Africa and, as fate would have it, a q...

Pseudoconfusion about Saturated Fat: Five Reasons for One Hot Mess

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...

Us and Them: The Sociobiology of Bias, Fear, and Hatred

David Katz, M.D. | Posted 07.14.2016 | Healthy Living
David Katz, M.D.

I concur with the New York Times editorialists who, among others, declared President Obama’s speech in Dallas this week a rhetorical highpoint of a ...

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 ...

Mountains, Prairies, Oceans, and Diets

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

The United States is beautiful, from its mountains, to its prairies, to its oceans, whether placid on a given day, or white with foam. It’s timely t...

Guns, Butter, and The Burden of Proof

David Katz, M.D. | Posted 06.22.2016 | Healthy Living
David Katz, M.D.

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

Of Course Obesity Rates Keep Rising!

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

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.

Animals, People, and the Humane

David Katz, M.D. | Posted 05.31.2016 | Healthy Living
David Katz, M.D.

Yes, we care for those we love -- but so do most if not all members of the mammalian class, and no small number of species in other classes as well. Some other mammals are as devoted in their fulfillment of parental obligation as the very best of us.

How Expertise Dies: Of Character, Credentials, and Crap

David Katz, M.D.

Perhaps no topic better illustrates the enormous gap between knowledge and ignorance, and its profound importance to the ambient understanding of all ...

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.

Invincible Food, Vulnerable Father and Son

David Katz, M.D. | Posted 05.18.2016 | Healthy Living
David Katz, M.D.

Where the likes of this pizza and sandwich, and soda and donuts and French fries are introduced, health is devastated, and in short order. Where just this sort of fare is removed to make way for more vegetables, fruits, beans, lentils, whole grains, nuts, seeds, and water when thirsty, the improvements in health are stunning.

KIND and Healthy Food Label Update by the FDA

David Katz, M.D. | Posted 05.13.2016 | Healthy Living
David Katz, M.D.

There is more to be done, but the FDA response to KIND, and their commitment to reevaluate the regulatory definition of "healthy" in light of current evidence and understanding, is meaningful progress, and full of promise for more.

Mechanics of Metabolism Maintenance: Cars, Keys, and Karelia

David Katz, M.D. | Posted 05.10.2016 | Healthy Living
David Katz, M.D.

The cottage industry in revisionist dietary history -- and make no mistake, it is an industry -- would have us believe that absurd misapplications of advice can be blamed on the advice itself. The dots, and decades, connecting Keys to Karelia, however, paint a very different picture.

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.

For Evil to Prevail

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

Whatever the intrinsic drama, though, and however often it need not apply -- there is, of course, evil in the world. There is avarice. There is corruption. There is exploitation. Anyone not holding such things to be self-evident, is evidently not paying attention.

Nutrient Supplements in the Land of the Law of Unintended Consequences

David Katz, M.D. | Posted 04.28.2016 | Healthy Living
David Katz, M.D.

Many supplements that don't work at all are marketed routinely, and some, very successfully. I have always maintained that this was a domain of both baby, and bathwater -- and that differentiating is essential.

Fixing Epidemic Obesity? We Have Never Tried...

David Katz, M.D. | Posted 04.26.2016 | Healthy Living
David Katz, M.D.

Similarly, I don't think we can say that historical advice about diet, health and weight control -- whatever the historical era, or advice -- is wrong because people subject to a diet of willfully addictive junk foods failed to follow it.

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.
