Can you eat your way to brain health?

A heart-healthy lifestyle is strongly associated with better memory and lower risk of Alzheimer's disease.

The health press is full of claims that "superfoods"—like fresh berries and leafy greens—can keep your memory sharp and hold the threat of Alzheimer's disease at bay. But for now, the evidence is preliminary at best. Your safest bet is to lead an overall heart-healthy lifestyle—including eating a plant-based diet and getting regular exercise—rather than drawing up a shopping list of alleged brain-boosting superfoods.
