Oz, to Ozymandias: Science, Soundbites, Symptoms and Systemic Disease

David Katz, M.D. | Posted 04.27.2015 | Healthy Living
David Katz, M.D.

Enough already about Dr. Oz. Whichever side you happen to be on, we might collectively acknowledge that much of the noise being made about what is, at...

Dietary Guidelines for Which Americans?

David Katz, M.D. | Posted 04.27.2015 | Healthy Living
David Katz, M.D.

At this point, the lid is off the box, and we know sustainability is a concern. We only have two choices: honor that concern, or dismiss it -- and knowingly eat at the expense of those to follow us.

Is the FDA unKIND?

David Katz, M.D.

Chances are, if you have ever ventured just about anywhere outside of your own house, that you are familiar with the increasingly ubiquitous KIND bars...

Exercise: the Luminous, Latent Potential of a Little Action

David Katz, M.D. | Posted 04.10.2015 | Healthy Living
David Katz, M.D.

There is an enormous benefit from even a little exercise, more benefit from more, and then a threshold past which returns diminish, but don't decline. The take-away message is that there is enormous potential for even a little bit of action to make our health, and lives, better.

Diet? I'll Have What He's Having!

David Katz, M.D. | Posted 04.07.2015 | Healthy Living
David Katz, M.D.

For those who don't know, that's really what the whole Blue Zones idea is about: a characterization of the lifestyle, behaviors, culture and environment of those populations around the world that live the longest and the best. They have the most vitality and the least chronic disease.

Breast Cancer Screening: Where Are We Now?

David Katz, M.D. | Posted 04.02.2015 | Healthy Living
David Katz, M.D.

Among the more important medical studies reported in recent weeks, even resulting in that rarefied "front page, above the crease" coverage by the New York Times, was a paper in JAMA indicating that the interpretation of breast biopsies is not the infallible gold standard we had hoped.

Do You (Really) Know What's Good for You?

David Katz, M.D. | Posted 03.30.2015 | Healthy Living
David Katz, M.D.

That our relationship with food, and its implications for our health, and that of the planet, are rather badly broken is quite clear. The better we can all say exactly how it's broken, the more likely any of us is to live long enough -- to see it fixed.

Appreciation for Brian Wansink, Run Amok

David Katz, M.D. | Posted 03.23.2015 | Healthy Living
David Katz, M.D.

As hoped, Brian and I see eye to eye. The factors that influence what people choose to do with food matter, but so too do the foods chosen, and what they do to the people. We need not choose to focus on one of these, and neglect the other.

Dietitians, Food and Truth: Winds of Change?

David Katz, M.D. | Posted 03.19.2015 | Healthy Living
David Katz, M.D.

In nutrition, though, we have long allowed foxes to guard the hen house. The easy access of Kraft to an apparent endorsement by the Academy of Nutrition and Dietetics is only the latest example, and by no means the worst.

Pi and Science, Sense and Cake

David Katz, M.D. | Posted 03.17.2015 | Healthy Living
David Katz, M.D.

When the beverage industry, for instance, helpfully points out that no long-term, randomized trial has specifically implicated their sugary concoction in epidemic childhood obesity, we might consider that no such trial has ever implicated any given snowflake in an avalanche fatality, either. Perhaps avalanches are actually innocuous.

An Apple a Day?

David Katz, M.D. | Posted 03.13.2015 | Healthy Living
David Katz, M.D.

We already have evidence of declining levels of empathy in the population at large, with frequent recourse to technological interfaces rather than direct eye contact one of the reasons invoked. The doctor-patient relationship has degraded too much already in my opinion. I would hate to see it technologized out of existence.

Dear Colleagues: We SUCK!

David Katz, M.D. | Posted 03.10.2015 | Healthy Living
David Katz, M.D.

I'm not saying we are wrong. In fact, we may all be right, about everything. But we are all right about disparate and seemingly-competing bits of the same, whole truth. The result is that nobody can see that whole truth.

Your Syndrome's Missing Benefit

David Katz, M.D. | Posted 03.06.2015 | Healthy Living
David Katz, M.D.

Doctors don't much care for conditions we don't understand well, can't treat effectively, and can't even confirm with a blood test. The frustration that results often translates into one of medicine's more common, and most regrettable missteps: blaming the victim. Patients with syndromes are often overtly, or at least covertly, blamed for their symptoms and engender an "it's all in his/her head" attitude in their doctor.

What Part of a Complete Breakfast?

David Katz, M.D. | Posted 03.06.2015 | Healthy Living
David Katz, M.D.

When dietary worry was all directed at excess fat intake, pseudo-fruit and multicolored marshmallows were able to fly under the radar. A widening array of worries has cost them that cover.

Avoiding Indictment by Innuendo

David Katz, M.D. | Posted 05.02.2015 | Media
David Katz, M.D.

When you go public with your opinions, you are apt at times to ruffle some feathers, intentionally or otherwise. I have dealt with this -- on television, on Twitter, and elsewhere -- many times. I have some suggestions for how best to dodge these bullets should you ever find yourself in similar crosshairs.

My Milk Manifesto

David Katz, M.D. | Posted 05.02.2015 | Healthy Living
David Katz, M.D.

We can take milk, or leave it. Take milk fat, or leave that. Either way, we can have a good diet of wholesome foods in sensible combinations -- or not. But either way, we need to take seriously the reverberations of our dietary choices across the landscape of a shrinking planet, and the legacy of kindness or cruelty by which history will be invited to judge us.

Isaac Newton's Nutrient Supplements

David Katz, M.D. | Posted 04.29.2015 | Healthy Living
David Katz, M.D.

The transcribed conversation in The Atlantic, starting with that headline, is rather the opposite of measured, taking the measure of prevailing sentiment, and apparently concluding that prevailing faith in nutrient supplements warranted some additional throttling. If enthusiasm for supplements is the action of concern here, this piece has opted to highlight the opposing reaction.

Enough Distractions: Let's Address the Real Causes of Diet-Related Diseases

Dr. Derek Yach | Posted 04.27.2015 | Healthy Living
Dr. Derek Yach

Placing the blame on carbohydrates does nothing but add confusion to an environment already saturated with mixed nutrition messages, and distracts us from addressing the real cause of the obesity epidemic: modern-day environments.

We're Fat And Sick And The Broccoli Did It!

David Katz, M.D. | Posted 04.26.2015 | Healthy Living
David Katz, M.D.

It's no big surprise that someone untrained in research methods would tell us all what the research really means and why the scientists on this committee -- all trained to do research and interpret it -- are just a bunch of hacks. But that the New York Times would allocate its imprimatur and rarefied real estate to an infomercial masquerading as an Op-Ed is a lamentably disappointing surprise.

My Kid Is an Animal! (And So Is Yours)

David Katz, M.D. | Posted 04.25.2015 | Healthy Living
David Katz, M.D.

The mission of the Unjunk Yourself videos is to take some of the messages about health passed around among concerned adults and convert them into a medium that is of, by, and for kids themselves.

Diet, Dog and Dogma

David Katz, M.D. | Posted 04.22.2015 | Healthy Living
David Katz, M.D.

Before the committee report is translated into official guidelines, there is a period of public comment.Some of the commentary will be from public health advocates, but much will be from industry. What exact dietary guidelines will emerge from this gauntlet remains to be seen. But given that, I like what I see so far. I think the advisory committee has done a stellar job.

Paleo for a Shrinking Planet?

David Katz, M.D. | Posted 04.21.2015 | Healthy Living
David Katz, M.D.

While many do, no one can say that a Paleo diet is best for health on the basis of truly robust evidence. But no one can say it isn't, either.

Cholesterol, Unscrambled

David Katz, M.D. | Posted 04.19.2015 | Healthy Living
David Katz, M.D.

Whether adding eggs to your diet will confer benefit, harm, or neither, almost certainly depends on what you are now eating instead of eggs, and what eggs would be displacing.

Where Public Health Meets Propaganda, You Are Being Played!

David Katz, M.D. | Posted 04.15.2015 | Healthy Living
David Katz, M.D.

But here's the thing, folks: if you buy into this nonsense, and meaning no disrespect, you are not merely wrong. You are wrong about why you are wrong.

The Case for a True Health Coalition: Who Hears Whom?

David Katz, M.D. | Posted 04.15.2015 | Healthy Living
David Katz, M.D.

With the strength of unity, a signal of what we truly do know can rise above the din and discord.
