CBS NEWS – People who follow a MIND diet, even if started later in life, were significantly less likely to develop Alzheimer’s disease or related forms of dementia, according to new research.
The MIND diet stands for “Mediterranean-DASH Intervention for Neurodegenerative Delay” and combines many elements of the Mediterranean diet and DASH (“Dietary Approaches to Stop Hypertension”). It emphasizes brain-healthy foods like leafy greens, berries, nuts and olive oil.
The study, being presented Monday at the American Society for Nutrition’s annual meeting, analyzed data from nearly 93,000 U.S. adults aged 45 to 75 starting in the 1990s.

This study joins previous research that has highlighted the benefits of eating a plant-focused diet to prevent the progressive brain disorder.
