A leafy green native of Asia, spinach was brought to Europe by the Moors when they conquered Spain in the eighth century.
With its bright green color, spinach is an excellent source of beta-carotene, plus vitamin C and folate. It's also one of the foods highest in the sight-saving nutrient duo - lutein and zeaxanthin.
Because spinach is on the Environmental Working Group's list of the most chemically contaminated foods - the Dirty Dozen - be sure to always pick organic.

Fresh spinach is available year-round. Choose leaves that are crisp and dark green with a nice fresh fragrance. Avoid those that are limp, damaged or which have yellow spots. Refrigerate in a plastic bag for up to 3 days. Spinach, which is usually very gritty, must be thoroughly rinsed.
