What does this mean for memory and Alzheimer's risk?
Close adherence to the MIND diet, a Mediterranean-DASH hybrid, was linked in observational studies to lower Alzheimer's risk and slower decline in older adults. Brain autopsies also found fewer Alzheimer's-related plaques and tangles in people who followed Mediterranean or MIND patterns.
The limit matters too. In a 3-year NIA-funded trial in 604 older adults with family dementia history, the MIND diet did not significantly outperform a mildly calorie-restricted control diet, and both groups improved, as summarized by the National Institute on Aging NIA summary on diet and Alzheimer's prevention. For broader protection, combine food with movement, not smoking, mental stimulation, and other healthy habits.
