A new study from Tufts University highlights the importance of carbohydrate quality for healthy aging, particularly in older women.
The research, published in JAMA Network Open, found a strong link between the consumption of dietary fiber and high-quality carbohydrates and better health outcomes in older women. "Healthy aging" was defined as the absence of chronic diseases, cognitive and physical impairments, and good mental health.
The study analyzed data from the Nurses' Health Study, involving 47,000 women who reported their dietary habits and health outcomes between 1984 and 2016. Women who consumed more high-quality carbohydrates from sources like fruits, vegetables, whole grains, and legumes were more likely to age healthily.
Conversely, the consumption of refined carbohydrates was associated with a reduced chance of healthy aging. The study also noted that higher intake of polyunsaturated fatty acids (PUFAs), commonly found in seed oils, was linked to decreased odds of healthy aging.
The findings suggest that prioritizing fiber-rich foods and minimizing refined carbohydrates can significantly support healthy aging and reduce the risk of chronic diseases. Experts recommend focusing on whole, unprocessed foods.
