'MIND diet' fails to deliver promised dementia prevention benefits, study finds

A three-year trial has found that the MIND diet, which is designed to prevent dementia, does not offer significant brain benefits over a standard diet. The trial involved 604 adults aged 65 and older who followed either the MIND diet or their usual diet with minor caloric restrictions. Both groups showed similar cognitive improvements, brain changes, and weight loss by the end of the study period. While large observational studies have linked the MIND diet to a lower rate of Alzheimer's disease and cognitive decline, this gold-standard clinical trial suggests that the short-term benefits may not be substantial.
