Celery

Peak Season: Year-round

Perfect Pick: Solid, tight stalks with only a few, if any, cracks and vivid green, not yellowing leaves. The darker the celery, the stronger the flavor.

Handle with Care: Sturdy celery can be stored in the fridge in a plastic bag for 2 weeks.

The Payoff: Luteolin, a flavonoid linked to reduced brain inflammation, a risk factor for Alzheimer's.
