Here on SBM we have frequently had cause to criticize the media for poor science reporting and for spreading misinformation. Among many other individual offenders, we have criticized Dr. Oz for promoting alternative medicine on his TV show and gullibly promoting guests who pretend to talk to the dead and pretend to heal people with carnival sideshow tricks. We tend to be negative and critical because somebody has to do it, but it’s not pleasant. For once, I have some good things to say.
The September 12 issue of TIME magazine was a Special Nutrition Issue. The cover featured pictures of food and the title “What to Eat Now: Uncovering the Myths about Food by Dr. Oz.” It devotes 7 pages to an article by him entitled “The Oz Diet: No more myths. No more fads. What you should eat — and why.” This is followed by a 5 page article by John Cloud “Nutrition in a Pill? I took 3000 supplements over five months. Here’s what happened.” Both articles have a rational, science-based perspective without any intrusions of woo-woo.
Oz on What to Eat
Oz acknowledges that the science of nutrition is not simple and that much of what we once believed has been discarded in the face of new knowledge. He debunks a number of popular misconceptions about diet. Most of what he says is consistent with scientific evidence and with mainstream diet advice. Read more »

It isn’t easy to get rid of a harmful habit like drinking too much, or to make healthy changes like losing weight and exercising more. Media stories about people who run marathons a year after surgery to bypass cholesterol-clogged arteries or who climb Mt. McKinley after being diagnosed with diabetes are interesting, but they don’t resonate with me. Mostly it’s because they often leave out the hard work needed to change and the backtracking that invariably accompanies it.
I ran across a truly inspiring story the other day in the American Journal of Health Promotion—one that shows how most of us ultimately manage to make changes that improve our lives. The journal’s founder and editor, Michael P. O’Donnell, wrote a moving essay about his father, Kevin O’Donnell. Once an overweight workaholic who smoked and drank heavily, ate mostly meat and potatoes, and didn’t exercise—and who eventually needed a double bypass—Kevin O’Donnell gradually made changes to improve his health. Now, at age 85, he has the cardiovascular system of a 65 year old and is working on a house-building project in North Korea.
How did Kevin O’Donnell engineer such a remarkable transformation? Read more »

Low-fat diets, move over. When it comes to lowering cholesterol, a “portfolio” diet that includes cholesterol-lowering foods such as oatmeal, nuts, and soy products is better.
Several years ago, researchers at St. Michael’s Hospital and the University of Toronto created what they called a “dietary portfolio of cholesterol-lowering foods.” It went after cholesterol by adding to a heart-healthy diet specific foods known to lower cholesterol: margarine enriched with plant sterols; oats, barley, psyllium, okra, and eggplant, all rich in soluble fiber; soy protein; and whole almonds.
In a head-to-head test against the low-fat diet traditionally recommended by the American Heart Association, the portfolio approach was the clear winner. (You can see the makeup of the test diet here.) After 24 weeks, it lowered harmful LDL cholesterol by 13%, while the low-fat diet lowered LDL by only 3%. As an added benefit, the portfolio approach also lowered triglycerides and blood pressure, and did not depress the level of beneficial HDL cholesterol. The results were published in the Journal of the American Medical Association.
What I appreciate about this study is that it Read more »

Eating a lot of chocolate was associated with a 37% reduction in cardiovascular disease and a 29% reduction in stroke compared eating less, researchers reported. But, people are trending toward record obesity by the year 2030, which is a cardiometabolic risk in its own right.
Willie Wonka’s factory wasn’t the only risky place for those with a sweet tooth.
In the first study, to evaluate the association of chocolate with the risk of developing cardiometabolic disorders, researchers performed a meta-analysis of randomized trials, six cohort and one cross-sectional, which reported the association between chocolate and the risk of cardiovascular disease (coronary heart disease and stroke), diabetes, and metabolic syndrome for about 114,000 people.
Because the studies reported chocolate consumption differently, researchers Read more »

Women gain weight after marriage and men after divorce, especially among those over 30, likely the result of “weight shock” to people’s routines in physical activity and diet, sociologists reported.
The research, led by a sociology doctoral student at The Ohio State University, was presented at a roundtable on Marriage and Family at the annual meeting of the American Sociological Association. They used data from the National Longitudinal Survey of Youth ’79, a nationally representative sample of men and women ages 14 to 22 in 1979. The same people were surveyed every year up to 1994 and every other year since then, reported a press release.
Data on more than 10,000 people surveyed from 1986 to 2008 was used to determine Read more »
