Diets rich in plant protein may help women stay healthy as they age
Protein, especially protein from plant-based sources, develop fewer chronic diseases and are more likely to be healthier overall as they age, according to a study led by researchers at the Jean Mayer USDA Human Nutrition Research Center on Aging (HNRCA) at Tufts University and published Jan. 17 in The American Journal of Clinical Nutrition.
Analyzing self-reported data from more than 48,000 women, the researchers saw notably less heart disease, cancer, and diabetes, and cognitive and mental health decline, in those who included more protein in their diets from sources such as fruits, vegetables, bread, beans, legumes, and pasta, compared to those who ate less.
“Consuming protein in midlife was linked to promoting good health in older adulthood,” said Andres Ardisson Korat, a scientist at the HNRCA and lead author of the study. “We also found that the source of protein matters. Getting the majority of your protein from plant sources at midlife, plus a small amount of animal protein seems to be conducive to good health and good survival to older ages.”
“Those who consumed greater amounts of animal protein tended to have more chronic disease and didn’t manage to obtain the improved physical function that we normally associate with eating protein,” said Ardisson Korat.
