Health Lunacy and Rocket Science

David Katz, M.D. | Posted 07.01.2015 | Healthy Living
David Katz, M.D.

We highlight a new celebrity cleanse and fad diet weekly if not daily on the morning shows; and the parade of best-selling quick fixes, each of which maligning all the others, seems never to end. And all the while, we mostly get fatter and sicker...

Outrageous Fortune

David Katz, M.D. | Posted 06.29.2015 | Healthy Living
David Katz, M.D.

In his famously febrile ruminations, Hamlet contemplated suicide as perhaps the one and only way to avoid the "slings and arrows of outrageous fortune...

Nutrients, Nutritionism, and Historical Nuttiness

David Katz, M.D. | Posted 06.24.2015 | Healthy Living
David Katz, M.D.

Recommending for the intake of nuts, but against the fat content of nuts, was always just plain nutty. Failure to learn from the follies of our nutritional history would be even more so.

I Hate Him

David Katz, M.D. | Posted 06.19.2015 | Religion
David Katz, M.D.

I worry that this primacy of hate over love means he and his kind have won something. I worry that my unwillingness to find forgiveness means I am surrendering something. I worry that for evil to prevail in the world it may be enough for bad people to make good people hate.

Big, Fat TRANSgression

David Katz, M.D. | Posted 06.18.2015 | Healthy Living
David Katz, M.D.

In other words, the best diet for our health depends, as it ever has, not on replacing trans fat with any one oil from any one nut up any one tree; but on seeing the forest.

Overcoming the Overweight We Keep Overlooking

David Katz, M.D. | Posted 06.16.2015 | Healthy Living
David Katz, M.D.

We can overcome the prevailing threat of obesity, but first, do need to stop overlooking it under our own roofs. We can overcome oblivobesity if we understand the tendency at its origins. When all is said and done, generally more than enough has been said, and not nearly enough has been done.

The Irrational Rationing of Health Care

David Katz, M.D. | Posted 06.12.2015 | Healthy Living
David Katz, M.D.

As I detailed in my prior column, Manny Alvarez is a 23-year-old college student with the misfortune of having not just a devastating cancer -- but th...

Rare Disease, Rare Indifference, and the Case for Our Righteous Indignation

David Katz, M.D. | Posted 06.09.2015 | Healthy Living
David Katz, M.D.

There are times when the addition of insult to injury warrants more than our forbearance. Sometimes, it warrants righteous indignation, and a revolt. ...

Earth: Cruise Ship or Life Boat?

David Katz, M.D. | Posted 06.04.2015 | Healthy Living
David Katz, M.D.

With more than seven billion of us established here, with California drying up, with climate changing and traditional crops failing, with extinctions accelerating and with environmental stresses globally near the breaking point, earth is no longer an unsinkable, titanic cruise ship.

Dietary Guidance: Sustainability or Stupidity?

David Katz, M.D. | Posted 05.27.2015 | Healthy Living
David Katz, M.D.

We only really have a choice between sensible guidelines that address sustainability, and senseless guidelines that dismiss the obvious. We only really have a choice between protecting our kids' food and water, and consuming it all. We only really have a choice between addressing a clear and present danger, and the shortsighted stupidity of ignoring it.

Newton, Nutrition, and the Tweets of Doom

David Katz, M.D. | Posted 05.27.2015 | Healthy Living
David Katz, M.D.

For all his contributions to science, controversial and otherwise, in modern context Sir Isaac Newton is most indelibly associated with one rather suc...

The Family Dinner

David Katz, M.D. | Posted 05.22.2015 | Healthy Living
David Katz, M.D.

The forests that produce our oxygen are in turn dependent on animal species that are sustained by them, and pay it back in various ways, such as by dispersing seeds. The vast interdependence of life is a bedrock principle of biology, from bees to buffalo to banyan trees. As glaciers melt and sea levels rise, our fellow species and we will sink or swim together.

Meals With Mephistopheles

David Katz, M.D. | Posted 05.15.2015 | Healthy Living
David Katz, M.D.

I don't appreciate the whole free will thing, but I am stuck with it. If you want to play let's make a deal, I'm ready any time. The future's on the menu, and I can really cook. So dinner is at my place, and I'll save you a seat at the table. As for saving anything else -- well, I guess that all depends upon your appetite.

Graduates: Rage Now!

David Katz, M.D. | Posted 05.12.2015 | Healthy Living
David Katz, M.D.

The righteous rage is all within you, and the roads along which to spend that rage to be the difference you hope to see in the world -- are all before you. And you are young, and foolish enough to believe in the possible.

The Pope, the Planet and Public Health

David Katz, M.D. | Posted 05.05.2015 | Healthy Living
David Katz, M.D.

As far as I can tell, there seem to be two basic religious attitudes toward the planet. One may be summed up along the lines of: It was made for us, a...

Health Promotion? Here's the Thing...

David Katz, M.D. | Posted 05.05.2015 | Healthy Living
David Katz, M.D.

There is no shortage of health promotion efforts in our world. Everyone hears about them all the time, and those inclined to tune in here to what I ha...

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

David Katz, M.D. | Posted 06.27.2015 | 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 06.27.2015 | 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. | Posted 06.16.2015 | Healthy Living
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 06.10.2015 | 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 06.07.2015 | 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 06.02.2015 | 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 05.30.2015 | 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 05.23.2015 | 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 05.19.2015 | 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.
