How Midlife Diet Relates to Cognitive Aging 

Healthier dietary patterns were associated with better later-life cognitive outcomes 

Share

A large prospective cohort study published in JAMA Neurology found a correlation between healthy dietary patterns in midlife and reduced risk of subjective cognitive decline (SCD) and better cognitive function in later life. Analyzed data from over 150,000 participants in the Nurses’ Health Studies and Health Professionals Follow-up Study indicated that adherence to six dietary patterns, particularly the DASH diet, was linked to a significant decrease in SCD risk. Emphasizing the importance of diet during ages 45-54, the study suggests dietary interventions could provide early prevention strategies for cognitive decline.
