A groundbreaking study from RUSH University in Chicago suggests that diets rich in green leafy vegetables, fruits, whole grains, and other healthy foods may significantly reduce the signs of Alzheimer’s disease in the brain.

Published in the Neurology journal, this study highlights the potential brain health benefits of following specific diets like the MIND and Mediterranean diets.

The Power of Diet in Brain Health

The research focused on the effects of the Mediterranean and MIND diets on brain health. These diets are known for their emphasis on plant-based foods, healthy fats, and lean protein sources.

The Mediterranean diet, in particular, encourages high consumption of vegetables, fruits, and fish, while the MIND diet places a strong emphasis on green leafy vegetables and berries.

Study Findings: Fewer Alzheimer’s Indicators

Involving 581 participants with an average age of 84, the study required participants to report their dietary habits through annual questionnaires.

Following their deaths, an average of seven years later, brain examinations revealed that 66% of them met the criteria for Alzheimer’s disease.

Notably, those who closely followed the Mediterranean and MIND diets had significantly fewer amyloid plaques and tau tangles, common indicators of Alzheimer’s disease, in their brains.

Green Vegetables: A Key Component

One of the standout findings was the impact of green leafy vegetables.

Participants who consumed seven or more servings per week of these vegetables had brain plaque levels corresponding to being nearly 19 years younger than those who consumed one or fewer servings per week.

This suggests a strong link between such dietary habits and maintaining cognitive health.

While the study reveals a promising association between these diets and reduced Alzheimer’s disease markers, it does not establish a direct cause-and-effect relationship.

Further research is necessary to confirm these findings and explore the potential of diet-based interventions in Alzheimer’s disease prevention and management.


This study from RUSH University presents compelling evidence that diets rich in green leafy vegetables, fruits, whole grains, and other healthy foods may play a significant role in protecting brain health and reducing the risk of Alzheimer’s disease.

As researchers continue to explore these findings, the importance of dietary choices in maintaining cognitive health becomes increasingly clear.
