Plant-Based Diet Linked to Lower Alzheimer’s Risk, Study Finds

A study of more than 92,000 adults found that healthier plant-based diets were linked to lower rates of Alzheimer’s disease and other dementias.

Diets higher in refined grains, sugary foods, and other less healthy plant-based items were associated with higher dementia risk.

In a smaller group, shifting toward healthier plant-based eating lowered risk, while moving toward unhealthy patterns worsened outcomes.

The findings suggest that plant-based diet quality, not just eating plant-based, may matter for long-term brain health.
