The new recommendations for healthy eating emphasize diet over individual nutrients and overturn some long-held beliefs.

Boosting your muscle mass may trigger changes that enhance heart health.

Munching a small handful every day may protect your heart.

Green vegetables and citrus fruits are good natural sources of folate.

If you're among the one in three American adults with high blood pressure, be sure you're getting enough of the B vitamin known as folate. Doing so may lower your odds of having a stroke, a new study suggests.

Cocoa flavanols in chocolate are linked to improved thinking skills and better heart health.

Supplements can plug dietary gaps, but nutrients from food are most important.

The fresh food you eat is loaded with nutrients necessary for good health, such as magnesium, calcium, and vitamins A and C. But many older adults aren't getting enough nutrients from their diets.

Health studies rarely involve people on opposite sides of the globe who have very different lifestyles. However, researchers at Vanderbilt Medical School took that approach when they pooled data from dietary studies of 72,000 men and women in the southeastern United States and 135,000 people in Shanghai, China. It turns out that the Americans and Chinese have something in common—they both eat a lot of peanuts—and they may be living longer as a result.

All of the participants filled out detailed questionnaires on the foods they ate regularly. The research team noted that peanuts accounted for 50% of nuts eaten by Americans and almost all the nuts consumed by the Chinese.

It's well known that women fall more often than men, but why is that so? A team of Canadian researchers tackled that question by looking for factors that tend to put women at higher risk than men for spills.

The researchers studied around 15,000 adults ages 65 and older who were enrolled in the Canadian Community Health Survey–Healthy Aging. All the participants were asked if they had suffered a fall serious enough to limit their normal activity. People who answered "yes" were then queried about their lifestyles and medical histories. When the researchers analyzed the answers, they determined that stroke, arthritis, and poor nutrition increased the risk of falls in both men and women. However, different risk factors were linked to falls for women, including being 85 or older, having at least one alcoholic drink a week, taking five or more medications, and having diabetes or osteoporosis. The findings were reported online Feb. 19, 2015, by the American Journal of Epidemiology.

Q. Why do people over 60 lose height? I've lost a few inches over the years. Can this be prevented?

They're linked to calorie absorption, high blood pressure, and heart trouble.

For weight-conscious people who love the bite of carbonation and the taste of various soft drinks, the advent of sugar-free sodas 60 years ago seemed a blessing: if there were no calories, you didn't have to worry about weight gain—and the diseases that go along with obesity, like diabetes and heart disease. "But there are growing doubts about whether diet sodas really help people lose weight and avoid diabetes," says Dr. Anthony Komaroff, editor in chief of the Health Letter.
