Carrots

Peak Season: Year-round

Perfect Pick: Smooth and firm with bright orange color. Avoid those that are bendable or cracked at the base, or that have patches of frosty white on their skin. Bunches with bright green tops still in place are your freshest choice.

Handle with Care: Store carrots with the greens removed in the crisper in a plastic bag for up to 3 weeks.

The Payoff: Beta-carotene, the source of vitamin A, which helps fight off infections.
