What women eat in midlife can influence their future health, a recent study suggests. Researchers have now found that women who include more plant-based protein in their diets tend to develop fewer chronic diseases as they grow older.
The team from the Jean Mayer USDA Human Nutrition Research Center on Aging (HNRCA) at Tufts University examined more than 48,000 participants to evaluate the long-term impact of dietary protein intake on healthy aging in women.
The research team noticed that women who included more protein from sources such as fruits, vegetables, bread, beans, legumes and pasta had reduced risk of heart disease, cancer and diabetes in comparison with those who did not consume a lot of these foods.
Participants who took in more plant-based proteins also had reduced cognitive and mental health decline. The study results were published in the American Journal of Nutrition.
“Consuming protein in midlife was linked to promoting good health in older adulthood. 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,” said Andres Ardisson Korat, lead author of the study, in a news release.
The participants were part of the Harvard-based Nurses’ Health Study, which followed female health care professionals between the ages of 38 and 59 from 1984 to 2016. All participants were in good physical and mental health at the start of the study.
The researchers examined thousands of surveys collected from the participants every four years during the follow-up period. The survey looked at the frequency at which people ate certain foods, particularly those with dietary protein, to understand its effects on healthy aging.
They then estimated the amount of protein intake by multiplying the frequency of each food by the protein content it had and added up all the protein from all the foods using the Harvard…
