Consuming more of these high-quality carbohydrates in middle age can help slow aging - both physically and mentally.

A new study conducted by leading American universities convincingly links the consumption of high-quality carbohydrates in middle age with healthier and more active longevity.

High-quality carbohydrates are not just any carbohydrates, but specifically those found in whole grains, fresh fruits, non-starchy vegetables, and legumes, reports Eatingwell. These nutrients have demonstrated an impressive connection with improved physical activity and cognitive health even decades later, dietitian Annie Nguyen emphasized in her commentary.

What you choose for your diet in your 40s and 50s can be a decisive factor in determining your rate of aging in later years. According to the results of the new study, women who regularly included more high-quality carbohydrates and fiber in their diet during middle age demonstrated significantly higher indicators of physical and cognitive health in old age - and they were less likely to develop serious chronic diseases, the dietitian notes.

Notably, low-quality carbohydrates, such as cookies and white flour pasta, showed a completely opposite effect, actually accelerating the aging processes.

Researchers from Tufts University and the Harvard T.H. Chan School of Public Health in their work came to an unambiguous conclusion: when it comes to the impact of carbohydrates on aging processes, their quality is what matters most.
