AI Insight
A study found that adherence to the MIND diet is associated with slower brain shrinkage and reduced grey matter loss over time. The strongest protective effects observed were equivalent to approximately 2.5 years of delayed brain aging. Specific foods showed differential associations, with berries and poultry linked to healthier brain outcomes, while sweets and fried fast foods correlated with greater tissue loss.
Why it matters
This research suggests that dietary interventions may offer a practical, modifiable approach to potentially slow age-related brain changes. The findings could inform nutritional guidelines aimed at maintaining cognitive health and preventing neurodegenerative decline in aging populations.
Understand the Science
People who followed the MIND diet more closely showed slower brain shrinkage and less grey matter loss over time, with the strongest differences equivalent to about 2.5 years of delayed brain aging. Berries and poultry were linked with healthier brain changes, while sweets and fried fast foods were associated with greater tissue loss.
