A large UK cohort study found that adults with healthier diets and lower waist-to-hip ratios during midlife had better brain connectivity and cognitive performance in later life. This study focused on 512 individuals in the diet cohort and 664 in the waist-to-hip ratio cohort from the Whitehall II Study, providing insights into the associations between diet quality, waist-to-hip ratio, brain connectivity, and cognitive performance as individuals age. The findings highlighted the potential impact of diet and obesity management on brain health and cognitive function in later life, particularly between the ages of 48 and 70. The study also revealed the importance of long-term dietary improvement for better brain outcomes.
