A study by DZNE finds that healthy eating is associated with slower biological aging—and that there is more than one way to eat healthily. The researchers examined 10 dietary patterns considered healthy, including the Mediterranean, Nordic, and a plant-based diet, as well as the DASH diet, which is designed to help lower blood pressure. All were linked with slower biological aging, with age-related changes in the DNA serving as markers.

Losing muscle as we age could be an important warning sign for dementia, according to new Curtin University research. Researchers analyzed more than 80 studies examining the links between body weight, body fat, muscle health and dementia, finding people with sarcopenia—the loss of muscle mass and strength—had a 42% higher risk of dementia. Sarcopenia is a condition in which people lose muscle mass, strength and physical function, often as they get older.

Structured exercise may help people with cancer live longer and have more time free of disease, finds a synthesis of the available evidence, published online in the British Journal of Sports Medicine.

Eating four to six servings of whole grains each day reduces several major risk factors for cardiovascular disease, according to a new study published in the European Heart Journal.

It includes data from 87 clinical trials that tested the effects of eating whole-grain foods on risk factors for cardiovascular disease.

Because couples who sleep together often eat together, one partner’s unhealthy food choices can have a ripple effect on the other’s eating habits, the researchers say.
