Overview
- The study analyzed over 47,000 women from the Nurses’ Health Study, tracking midlife diets from 1984–2016 and health outcomes in later life.
- Healthy aging was defined as the absence of 11 major chronic diseases, preserved cognitive and physical function, and good mental health, met by 3,706 participants.
- Higher intakes of high-quality carbohydrates—such as those from whole grains, fruits, vegetables, and legumes—and dietary fiber were associated with a significantly higher likelihood of healthy aging.
- Conversely, diets high in refined carbohydrates, including added sugars, refined grains, and starchy vegetables, were linked to a 13% lower likelihood of healthy aging.
- The authors emphasized the need for further research into the biological mechanisms and replication of findings in more diverse populations beyond the predominantly white cohort.
