Higher overall diet quality, measured by the modified Alternative Healthy Eating Index (mAHEI), is associated with a significantly reduced risk of cognitive decline in high-risk cardiovascular patients.

Adopt a diet high in vegetables, fruits, whole grains, nuts, and soy, while limiting deep-fried foods and red meat. This pattern, measured by the modified Alternative Healthy Eating Index, is associated with a 24% lower risk of cognitive decline in high-risk individuals. Focus on consistent, long-term adherence to these core food groups rather than short-term restrictive diets.

GoodSupportsHIGH confidence
We found that higher diet quality was associated with a reduced risk of cognitive decline. Improved diet quality represents an important potential target for reducing the global burden of cognitive decline.

Why this rating

Large multinational cohort (n=27,860) with robust statistical adjustment, but observational design limits causal inference.
