In-Season Superfood: Walnuts

"Nuts give sweet or savory dishes flavor, crunch, and a heart-healthy
punch. Even better? Walnuts scored highest of all nuts in the omega-3s
that protect against heart disease. And their stores of fiber and
unsaturated fat can help you lower "bad" LDL cholesterol naturally.
To preserve taste and prevent spoiling, keep shelled nuts refrigerated
in an airtight container for up to 6 months or in the freezer for up
to a year."
