The Devil in The Disagreement: Lynching in Lieu of Listening

David Katz, M.D. | Posted 11.05.2014 | Healthy Living
David Katz, M.D.

Differing opinions about eating well seem a very strange reason to form lynch mobs, but something very much like that goes on all the time.

Diet Research, Stuck in the Stone Age

David Katz, M.D. | Posted 11.02.2014 | Healthy Living
David Katz, M.D.

This was a study designed to generate a predictably useless, misleading, and potentially harmful answer to an egregiously silly and perhaps even willfully disingenuous question. If science were generally this bad, we would never have exited the Stone Age.

Loving Food That Loves Us Back, Extra Space at The Table

David Katz, M.D. | Posted 11.02.2014 | Healthy Living
David Katz, M.D.

There is a geographical midpoint between living to eat, and eating to live. It's where health comes from the pursuit of pleasure, and pleasure comes from the pursuit of health.

Obesity on the Nile

David Katz, M.D. | Posted 10.29.2014 | Healthy Living
David Katz, M.D.

Should we know whether or not our kids, or ourselves, are overweight? Of course, just as we should know -- before a mechanical calamity -- that the oil in our car needs changing, or our tire pressure is low.

Lifestyle Medicine: Have Hammer, See Nails, Seeking Spoon

David Katz, M.D. | Posted 10.27.2014 | Healthy Living
David Katz, M.D.

Famously, when you have a hammer, you tend to see nails everywhere you look. As president of the American College of Lifestyle Medicine, then, perhaps it's no surprise that I see opportunity to apply this remedy everywhere I look. Lifestyle medicine is my hammer.

Your Doctor's Knee-Jerk Reflex: How Not to Get Kicked

David Katz, M.D. | Posted 10.20.2014 | Healthy Living
David Katz, M.D.

Clinical assessment that includes a test of the knee jerk reflex is fine. Clinical decisions driven by it are not, but they too, are out there.

Sodium Studies, With a Grain of Salt

David Katz, M.D. | Posted 10.18.2014 | Healthy Living
David Katz, M.D.

It is theoretically possible to consume too little sodium, but whether the relevant cut-point is set high or low, the vast majority of adults living in the real world consume too much.

The Keys to Good Health

David Katz, M.D. | Posted 10.14.2014 | Healthy Living
David Katz, M.D.

Rather, leaving aside the swirl of aspersions that likely has Dr. Keys turning in his grave if such things are possible, I simply want to note that his work is...moot. It doesn't matter whether Keys was all right, all wrong, or inevitably -- somewhere in between.

Under Our Skin

David Katz, M.D. | Posted 10.12.2014 | Healthy Living
David Katz, M.D.

Mr. Williams was a far better actor than most of us, so his veneer was more elaborate. But all the world's a stage, and we all -- players, too. Such veneers abound. Perhaps we could keep it in mind, and give one another the benefit of prevailing doubt.

Aborted Thinking

David Katz, M.D. | Posted 10.08.2014 | Healthy Living
David Katz, M.D.

We all like autonomy, and all concede it has to end somewhere. As I once heard an ethicist quip, my autonomy to swing a stick certainly ends where your nose begins.

Rabid Opposition to Ebola: Epidemiology Meets Hyperbole

David Katz, M.D. | Posted 10.04.2014 | Healthy Living
David Katz, M.D.

There is certainly no basis for either fear of, or opposition to, the on-going treatment of an infected American doctor in Atlanta. We may instead all be thankful that in return for the courageous service he was providing in Liberia, Dr. Brantly is now receiving an American standard of medical care himself.

Processing Messages About Processed Food

David Katz, M.D. | Posted 10.04.2014 | Healthy Living
David Katz, M.D.

The American Society of Nutrition issued what proved to be a very controversial position paper on processed foods. The basic take-away message that resulted, if there is one, is that processed foods are certainly not all bad.

Massachusetts Chooses a Governor: Implications for Us All

David Katz, M.D. | Posted 09.27.2014 | Healthy Living
David Katz, M.D.

As a pediatrician in some of Boston's lowest-income neighborhoods, I saw firsthand how a child's health is determined by far more than medicine -- it is the air they breathe, the streets they play in, the safety of their communities, their opportunities for a good education, the economic stability of their family. Simply put, doctors can't fulfill their mission in communities affected by inequality and unfairness. Health requires justice for all. That's what makes me want to run for governor.

What to Do When Your Food Glows in the Dark

David Katz, M.D. | Posted 09.24.2014 | Healthy Living
David Katz, M.D.

Perhaps it's an exaggeration to say our food glows in the dark, although I'm not entirely sure. But whether or not they actually phosphoresce, these products are indeed designed to glow. The glowing in question, however, occurs within the dark confines of our skulls.

A Simple Prescription for Lower Health Care Costs

Angela Perkey | Posted 09.22.2014 | Healthy Living
Angela Perkey

Countless books have been written about the need to change habits and live a healthy lifestyle. Yet it's clear just by looking at obesity rates that there is much to be done to improve the American lifestyle.

No Taste for Truth?

David Katz, M.D. | Posted 09.20.2014 | Healthy Living
David Katz, M.D.

Rather than supporting the health of our bodies, our body politic is feeding off their willfully devised decay.

Lifestyle Medicine and the Parable of the Tiny Parachute

David Katz, M.D. | Posted 09.16.2014 | Healthy Living
David Katz, M.D.

A commentary was published last month on the blog site of the prestigious British Medical Journal telling us, in essence, that lifestyle medicine is ineffective. Specifically, it said that screening for chronic disease risk factors in the general population, and addressing them with lifestyle counseling in the clinical setting, is of no value.

Perils of Fire Fighting: Too Much Heat and Too Little Light

David Katz, M.D. | Posted 09.13.2014 | Healthy Living
David Katz, M.D.

We just got a bracing dose of this reality in a report issued by the CDC. The rate of overweight and obesity is higher among fire fighters -- at 70 percent -- than the general population.

The Urgencies of Care: Here, There and Everywhere

David Katz, M.D. | Posted 09.10.2014 | Healthy Living
David Katz, M.D.

Access to care is an important element in the quality of both health care, and the overall public health. All too often small problems neglected for a while turn into larger problems. Barriers to care propagate just such costly misfortune.

Knowing What to Eat, Refusing to Swallow It

David Katz, M.D. | Posted 09.01.2014 | Healthy Living
David Katz, M.D.

The argument for an emphasis on actual foods rather than manufactured ingestibles masquerading as such garners little opposition from entities not directly involved in selling the latter. Such entities, however, have access to the best marketing talent money can buy.

More Health Care vs. More Health

David Katz, M.D. | Posted 08.27.2014 | Healthy Living
David Katz, M.D.

We may at times think too much. There is no shortage of very intelligent, highly educated people in my academic world. But perhaps there is something seductive about the pursuit of data that causes some in this domain to think that the pursuit of data is itself the objective. It shouldn't be. What most people want is for the data we derive to be applied to some

The Fate of Front-of-Pack Labeling That Actually Works

David Katz, M.D. | Posted 08.27.2014 | Healthy Living
David Katz, M.D.

News came in the past week that the front-of-pack nutrition guidance program offered by Canada's Heart and Stroke Foundation, presented as a seal of approval in the form of a check mark, was being decommissioned. With all due respect to my friends at the Foundation, and the good intentions that brought the system into existence -- good riddance to it.

Study: Saturated Fat as Bad as Sugar!

David Katz, M.D. | Posted 08.18.2014 | Healthy Living
David Katz, M.D.

Folks, when it comes to food, and food for thought alike, it is mostly stupidity that is killing us. Stupidity is worse for us than either sugar or saturated fat.

Fat: Ending the War That Nobody Started

David Katz, M.D. | Posted 08.16.2014 | Healthy Living
David Katz, M.D.

The evidence continues to accrue -- with almost surprising frequency -- that we should, indeed, eat less meat, butter, and cheese (before we even factor in the environmental considerations, which frankly we should do). We just shouldn't replace them with donuts, Snackwells and soda.

Research Funding: When Is the Money Dirty?

David Katz, M.D. | Posted 08.13.2014 | Healthy Living
David Katz, M.D.

All research starts with biased funders and researchers -- because in the absence of such bias, it would be research no one would bother doing. I don't think anyone runs studies in the absence of hopes and preferences pertaining to the outcomes.
