The people you live with, work with, talk to, email, chatter with on Twitter and Facebook—your social network—can be good medicine, or bad.
The intriguing new science of social networks is demonstrating how personal interconnections can affect our health. Ideas and habits that influence health for better or for worse can spread through social networks in much the same way that germs spread through communities. In social networks, though, transmission can happen even though the people may be hundreds of miles apart.
An article in the December issue of the Harvard Men’s Health Watch explores how social networks can affect weight and mood.

A study published in the journal Academic Pediatrics reveals that 93% of California children’s hospitals offered unhealthy food to outpatients, visitors and staff in the cafeteria and snack bars. Said another way, only 7% offered healthy food. What did these foods consist of to be called “unhealthy”? Try fried food, sweetened beverages, burgers and lots of sugary sweets.
The study found that 81% of the cafeterias placed high-calorie, high-sugar items like ice cream right by the cash register, a well known marketing plan to tantalize and increase selection. Forty four percent didn’t even offer low calorie salad dressing and fewer than 1/3 had no nutrition information.
Health care workers, like the rest of America, suffer from increasing obesity. One study showed over 54% of Read more »

These days, most adults are overweight, not active, or both. If you could change just one—become active or lose weight—which would be better?
At least for men, being more fit may have a bigger health payoff than losing weight, according to a new study of more than 14,000 well-off middle-aged men who are participating in the Aerobics Center Longitudinal Study. Researchers followed their health, weight, and exercise habits for 11 years. They estimated how physically fit the men were by calculating their metabolic equivalents (METs) from a treadmill test.
Compared with men whose fitness declined over the course of the study, those who maintained their fitness levels reduced their odds of dying from cardiovascular disease or any other cause by about 30%, even if they didn’t lose any excess weight. Those who improved their fitness levels saw a 40% reduction.
Body-mass index (BMI), a measurement that takes weight and height into account, was not associated with mortality. The results were published in the journal Circulation.
What is “fitness”

A simple optical illusion might encourage better eating habits, researchers found.
The Delboeuf illusion makes equal size circles appear to be different sizes by surrounding them with larger or smaller concentric rings. Applied to eating, smaller plates make the food servings appear larger.
One problem is that the size of commercially available dinnerware has increased from 9.6 inches to 11.8 inches in the past century. Eating only 50 calories a day more as a result equals enough calories to add five pounds of weight annually.
Practical implications of the research include encouraging people to replace larger plates and bowls with smaller ones, choose plates that contrast starkly with food, and even choose tablecloths that match their dinnerware, the researchers noted. Those with eating disorders or elderly people who need to eat more could follow the opposite advice to improve their intake.

There was a very controversial presentation made at a recent meeting of heart doctors in Canada. I’ve been stewing about what to say about it for a week.
The title speaks to its inflammation:
Fat, unfit, unmotivated: Cardiologist, heal thyself
The presenter that made the stir, pediatric cardiologist, and IronPerson, Dr. Brian McCrindle (Toronto) argued that overweight, unfit doctors are doing their patients a disservice. His bottom line: cardiologists are acting like the rest of Western society. They are not living a healthy lifestyle.
He made three major points. (in-depth coverage can be viewed here, on TheHeart.org)
