A healthy diet may help ward off Alzheimer's disease.

Researchers studied 20 older healthy adults and 29 others who had some memory problems. They randomly assigned them to eat either healthy or unhealthy diets for four weeks.

Researchers then measured their levels of biomarkers associated with Alzheimer's disease. Those who ate the unhealthy diet had changes in their biomarkers that could indicate detriments to brain health. Those who ate healthy diets had the opposite effect on their biomarkers.

The study was published in the June issue of the journal Archives of Neurology.
