Why Success Is Always 'Iffy'

(0) Comments | Posted July 28, 2015 | 10:12 AM

2015-07-28-1438092695-1997832-cactusflower.jpg

I would love to identify some cadre of constantly buoyant motivational speakers, or perennially jocular optimists as my trusted arbiters of success. I would love to, but alas, I just can't. I seem constitutionally prone to go blind while wearing...

One Minute Longer

(2) Comments | Posted July 24, 2015 | 9:54 AM

One of my favorite books as a child was called, if memory serves, Favorite Dog Stories. I rather doubt the collection had much genuine literary merit. But I was a kid and very much loved my dog then, as I love my dogs now -- and I loved the stories...

Zeal, Veal and Veganism

(2) Comments | Posted July 20, 2015 | 4:12 PM

When my vegan friends and colleagues say that a vegan diet is categorically the best for human health, it is an excess of zeal. We simply do not have evidence to substantiate the claim. I know; I've looked- hard.

If you are inclined to...

Health Care Rationing: The Roar and the Silence

(3) Comments | Posted July 17, 2015 | 11:52 AM

I have gotten the impression over my years in medicine that essentially no one likes to talk about rationing care. Those who oppose the concept on ideological grounds certainly don't want to talk about it. Those who are in acute need of care for themselves or someone they love are...

Ending the Big, Fat Debate

(1) Comments | Posted July 15, 2015 | 6:22 PM

Achieving a clear understanding of the health effects of dietary fats requires a challenging slog through a thick tangle of opinions. These days, it's rare to get through any given news cycle without contentions about dietary fat, expert and otherwise, coming at us from every quarter. The preoccupation, especially intense...

Eating in Echo Chambers

(0) Comments | Posted July 9, 2015 | 1:59 PM

In Going to Extremes, Cass Sunstein explores and characterizes the process that can lead to religious fundamentalism, internecine hatreds, jihad, and suicide terrorism. The essential ingredient is an echo chamber, a place where the opinion to which you are natively inclined, for whatever reasons, is reflected back...

Cancer Mortality News, Between the Lines

(0) Comments | Posted July 6, 2015 | 4:13 PM

A CDC report just released indicates that the age-adjusted risk of cancer death is declining for Americans overall, and the trajectory is largely in line with the aspirational objectives of Healthy People 2020. There are several, salient messages in this report- and at least...

Health Lunacy and Rocket Science

(0) Comments | Posted July 1, 2015 | 3:22 PM

The failure to use what we have known for more than two decades to prevent up to 80 percent of all major chronic disease -- heart disease, cancer, stroke, diabetes, dementia -- is costing virtually every one of us years lost from lives we love, and life lost...

Outrageous Fortune

(0) Comments | Posted June 29, 2015 | 1:05 PM

In his famously febrile ruminations, Hamlet contemplated suicide as perhaps the one and only way to avoid the "slings and arrows of outrageous fortune." However grave the demerits of his melancholy inclination, his basic conclusion on the topic may well have been correct.

Worded differently: stuff happens.

Nutrients, Nutritionism, and Historical Nuttiness

(0) Comments | Posted June 24, 2015 | 6:23 PM

The current issue of JAMA features a commentary by two colleagues, calling for an end to what they term the "ban" on total dietary fat. More specifically, the authors are endorsing the report of the 2015 Dietary Guidelines Advisory Committee, of which I too...

I Hate Him

(2) Comments | Posted June 19, 2015 | 1:21 PM

Views on god and religion vary widely, of course. My own views are likely rather transparent to those who pass this way routinely, but are immaterial either way. We may, I trust, agree -- whether we endorse a god of personal attachment, a god detached and dispersed to the far...

Big, Fat TRANSgression

(1) Comments | Posted June 18, 2015 | 5:31 PM

Trans fat is going, if not yet gone, and good riddance to it. The word on the street is that the FDA is acting to "ban" partially hydrogenated oils from the food supply. The slightly more banal reality is that the agency is finalizing an action, begun two...

Overcoming the Overweight We Keep Overlooking

(4) Comments | Posted June 16, 2015 | 5:18 PM

The New York Times has attributed the term "oblivobesity" to me, and rightly, so far as I know; I did, indeed, coin the expression. It refers to the overweight under our own roofs that we are prone to keep overlooking, most notably that in our own...

The Irrational Rationing of Health Care

(3) Comments | Posted June 12, 2015 | 6:33 PM

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 the wrong devastating cancer. The chemotherapeutic agents shown to be highly active against his specific tumor cells are FDA approved for the treatment...

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

(2) Comments | Posted June 9, 2015 | 10:42 AM

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

The insult in question is the denial of coverage for care by Blue Cross Blue Shield of Florida.

Earth: Cruise Ship or Life Boat?

As I write this, I am returning to the U.S. from Stockholm, Sweden, where I was privileged to participate in the EAT Stockholm Food Forum.

Dietary Guidance: Sustainability or Stupidity?

(2) Comments | Posted May 27, 2015 | 5:24 PM

As a writer, I recognize the need to be blunt at times to deliver a message effectively. I don't shy away from that requirement, but I do try to avoid insult. For one thing, you cannot communicate effectively with someone you alienate. For another, I have far too...

Newton, Nutrition, and the Tweets of Doom

(3) Comments | Posted May 26, 2015 | 9:22 AM

For all his contributions to science, controversial and otherwise, in modern context Sir Isaac Newton is most indelibly associated with one rather succinct assertion of physical truth: For every action, there is an equal and opposite reaction.

Were the governance of this third law of motion limited...

The Family Dinner

(0) Comments | Posted May 22, 2015 | 10:18 AM

The family dinner may itself be an endangered species in this modern era of fast food, electronic distractions, and isolated eating on-the-fly. The composition of that meal may be among the reasons other species are endangered, and that confluence is today's harangue. But we may begin with our own species.
