The idea
In a three-year randomized trial, older adults on the MIND diet improved in cognition no more than a control group on a similar calorie-reduced diet.
In practice
Both groups' cognitive scores rising slightly, with brain scans similar in the two groups.
Where people slip
Observational links between diet and dementia do not guarantee that changing diet prevents decline; trials test the causal claim.
