Older adults could greatly benefit from breaking up their sedentary time throughout the day, even if it’s just shifting from sitting to a standing position, according to a new study.
“As a general finding, older adults should make nine interruptions for every hour spent in sedentary behavior,” said Luís B. Sardinha of the Exercise and Health Laboratory at the University of Lisbon in Portugal.

Eat real food, as close to nature as possible. It’s what we do to food that is a problem — processing, refining, reducing and altering in general. Forget about reduced fat and skim milk. The less processing the better. If you’re going to eat fat, choose good quality and go for full-fat. … fats are important for satiety, absorption of minerals, fertility, skin, hair, nails, memory — I could go on. …
Eating “fat” is not what makes us fat. Trimming the fatty part off your steak isn’t what’s going to prevent you from gaining weight, but cutting out the dinner rolls and all the sodas you’re drinking throughout the day will. We now understand that weight gain is very closely linked to insulin production — foods that cause spikes in our glycemic index (i.e. sugars) are largely responsible for fat production.

Lower-extremity stress fractures often occurred in association with potentially modifiable muscular and biomechanical factors, according to a study of 1,800 military cadets. …
Internal knee rotation >5 degrees more than doubled the likelihood of lower-extremity stress fracture as compared with cadets who had neutral or external knee rotation alignment.

From Slate:
Americans die younger and experience more injury and illness than people in other rich nations, despite spending almost twice as much per person on health care. That was the startling conclusion of a major report released earlier this year by the U.S. National Research Council and the Institute of Medicine. …
The poorer outcomes in the United States are reflected in measures as varied as infant mortality, the rate of teen pregnancy, traffic fatalities, and heart disease. Even those with health insurance, high incomes, college educations, and healthy lifestyles appear to be sicker than their counterparts in other wealthy countries. The U.S. Council on Foreign Relations, a nonpartisan think tank, described the report as “a catalog of horrors.” …
As distressing as all this is, much less attention has been given to the obvious question: Why is the United States so unwell? The answer, it turns out, is simple and yet deceptively complex: It’s almost everything.
