We Can Be Disease-Proof!

David Katz, M.D.

Without the right skill set, health is elusive. You can't get there from here. The relevant skills are yours for the taking, and with them, you and those you love truly can be to an astonishing degree, disease-proof.

Being Less Dense About Breast Cancer Screening

David Katz, M.D. | Posted 11.13.2013 | Healthy Living
David Katz, M.D.

A false sense of security from a "normal" mammogram in a woman with dense breast tissue is just the kind of trouble we want to avoid. And while mammograms save lives, they have limitations- and the best screening programs account for them.

Our Severely-Obese Daughters and Sons: Of Pennies, Pounds and Sense

David Katz, M.D. | Posted 11.13.2013 | Healthy Living
David Katz, M.D.

Obesity is a cultural problem and requires a cultural solution we have the knowledge and means to administer. That we fail to apply those means bespeaks our ambivalence at best, our profit-driven hypocrisies at worst.

Genes, Germs and Girth

David Katz, M.D. | Posted 11.10.2013 | Healthy Living
David Katz, M.D.

The more we've learned about the importance of our resident microbes, the more we've learned about the need and opportunity to learn more. The process may be likened to climbing a hill, and then gaining a view of the higher hills and mountains beyond. There is a lot of climbing left to do.

Enough Flu-ing Around!

David Katz, M.D. | Posted 11.06.2013 | Healthy Living
David Katz, M.D.

The flu vaccine is far from perfect. It can fail to prevent flu and there can be rare complications. But it usually does prevent flu, and complications of the flu itself are more common by literal orders of magnitude.

Parents, Presidents, Provocations and Principles

David Katz, M.D. | Posted 11.05.2013 | Politics
David Katz, M.D.

As a parent, I see no way to ignore the flagrant violation of international law in Syria and not rue the choice. I realize as well that international law is violated often around the world. But we can't fix what we don't know is broken, and much of such abuse takes place in shadow.

Fixing Obesity, Between Little Rock and Hard Places

David Katz, M.D. | Posted 10.29.2013 | Healthy Living
David Katz, M.D.

I was privileged to be in rooms full of people passionate about the obesity challenges in Arkansas and prepared to work hard. Everyone around me seemed realistic about the challenges and was lacing up his or her hiking boots accordingly.

Social(organ)ism

David Katz, M.D. | Posted 10.26.2013 | Healthy Living
David Katz, M.D.

Socialism is a dirty word, perhaps deservedly so. But the real trouble resides with our persistent use, and misuse, of a word we made dirty. Vocabulary so encumbered is like bathwater we refuse to drain; it takes on an opacity that quite obscures the baby

Of Lyme Disease, and Lemonade

David Katz, M.D. | Posted 10.23.2013 | Healthy Living
David Katz, M.D.

Lyme is common, but no more so now than before this report -- this is simply recognition of what has been, not a portent of some new threat to come.

Your Medication Can Kill You!

David Katz, M.D. | Posted 10.16.2013 | Healthy Living
David Katz, M.D.

Yes, side effects of medications can kill. But so can the side effects of declining medications we really need. When prescribed judiciously by clinicians who know what they are doing to patients who know what they are getting, drugs are far more likely to help than harm.

Finding Health, Keeping the Money: Needles in the Nation's Haystacks

David Katz, M.D. | Posted 10.13.2013 | Healthy Living
David Katz, M.D.

Subsidizing better choices in the grocery store is a lot less expensive than stays in the intensive care unit. We don't need to prevent very many cases of diabetes, heart disease or bariatric surgeries to save back the costs of incentives for nutritious foods, 10 times over.

Pediatric Obesity, Ping-Pong, and Puzzle Pieces

David Katz, M.D. | Posted 10.12.2013 | Healthy Living
David Katz, M.D.

The picture suggests, encouragingly, that widespread attention to the crisis of childhood obesity can make a difference, and is seemingly starting to do so -- for some of the kids in some of the places at least some of the time.

Why Dieting Must Die

David Katz, M.D. | Posted 10.05.2013 | Healthy Living
David Katz, M.D.

If you doubt that children are endangered by obesity and its metabolic complications, you simply haven't been paying attention. And so my simple assertion is that the neglect is the same in both cases: feeding yourself as your children starve, or dieting while your children get fat.

Fructose, Fruit, and Frittering

David Katz, M.D. | Posted 10.02.2013 | Healthy Living
David Katz, M.D.

Why does anyone need to make a case for eating fruit? We have cited the combination of "fruits and vegetables" as the cornerstone of healthful eating throughout the entire era of modern nutrition, and it has been so since before the advent of modern humans.

74th Birthday, 54 Miles

David Katz, M.D. | Posted 09.29.2013 | Healthy Living
David Katz, M.D.

A 54-mile bike ride to celebrate a 74th birthday is, indeed, very cool -- for many reasons. My father's lifelong devotion to physical activity is partly responsible for my own.

Digesting The Implications Of Breakfast

David Katz, M.D. | Posted 09.28.2013 | Healthy Living
David Katz, M.D.

Research about breakfast tends to divide the world into those who skip and those who don't. But deferring and skipping are not the same. Skipping despite hunger, and deferring for want of it, are not the same. And clearly all breakfasts are not created equal.

Estrogen and Evidence

David Katz, M.D. | Posted 09.22.2013 | Healthy Living
David Katz, M.D.

We are certainly not saying that every woman with a hysterectomy should take estrogen. Our argument is exactly against the oversimplification of one-size-fits-all approaches.

Lethal Placebo

David Katz, M.D. | Posted 09.18.2013 | Healthy Living
David Katz, M.D.

All forms of hormone replacement for all women at menopause was never right, but nor is NO forms of hormone replacement for NO women at menopause. There was always baby and bathwater here, and we have egregiously failed to distinguish between the two.

Fish Tales and Prostate Cancer

David Katz, M.D. | Posted 09.17.2013 | Healthy Living
David Katz, M.D.

Is it plausible that higher omega-3 intake increases prostate cancer risk, but decreases breast cancer risk? I suppose the subtleties of carcinogenesis might allow for it, but I find it very far-fetched; if it doesn't stretch the envelope of credibility to the tearing point, it sure comes close.

Bunk About Junk Food

David Katz, M.D. | Posted 09.11.2013 | Healthy Living
David Katz, M.D.

While I agree that we can benefit from choosing a better chip, I think it's flaky at best to suggest that junk food will ever be beneficial. It is, in fact, oxymoronic -- give or take the oxy. If a food is good for us, it isn't junk.

Being Human First

David Katz, M.D. | Posted 09.10.2013 | Healthy Living
David Katz, M.D.

I am by no means suggesting that every doctor, or members of any given profession, should all be humanities majors. But a general decline in our respect for and attention to the humanities may be at our collective peril.

Clinical Karma

David Katz, M.D. | Posted 09.07.2013 | Healthy Living
David Katz, M.D.

Having medical training is a great privilege, and the source of, at times, quite literal life and death power. With that power comes a grave responsibility -- but bearing that is a privilege as well. Medical training is not a product of good fortune, but of willful preparation.

Fructose and the Follies of History

David Katz, M.D. | Posted 09.06.2013 | Healthy Living
David Katz, M.D.

A fixation on any nutrient property in isolation is a gilded invitation to the food industry to give us a whole new parade of products boasting that attribute, no matter what else might be in the mix.

Fast Food Fantasy

David Katz, M.D. | Posted 08.31.2013 | Healthy Living
David Katz, M.D.

Imagine if we -- the food customers -- rallied around a higher standard to serve our collective satisfaction. Could we really stand up to Big Food? Would we be biting off more than we could hope to chew and swallow, or might we really change the food supply?

Is It Wrong to Market Even Healthy Food to Kids?

Bettina Elias Siegel | Posted 08.26.2013 | Parents
Bettina Elias Siegel

No amount of legislation could entirely insulate children from food advertising in today's world, where even the inside of the bathroom stall is now considered fair game for marketers.
