WHY YOU NEED THEM
They'll keep your ticker beating at its ideal rhythm. That extra cardio protection comes from two compounds (hesperidin and naringin) found in the peel and inner white pulp. In studies, the duo have been shown to potentially ward off heart disease and stroke by elevating levels of good cholesterol while reducing the risk of clots.
Oranges fi ght off damage from the sun. Orange peel is loaded with the protective phytonutrient d-limonene. Eating as little as one tablespoon of orange zest each week—about the amount from one orange peel—can significantly suppress your risk for skin cancer. For the greatest effect, combine orange zest with hot black tea.
NOTE: To get zest, rub an unpeeled orange against a food grater with fine holes. The resulting bits of peel—or zest—can be used in salads or soups or sprinkled over chicken or fish before cooking.
Citrus fruits may fight the signs of aging. The vitamin C in oranges can neutralize free radicals, preventing them from damaging cells and triggering everything from fi ne lines and wrinkles to more serious illnesses like cancer. And just taking a supplement won't do. Italian researchers found that volunteers who drank OJ had far less cellular damage from free radicals than another group who took the same amount of C in vitamin form.
If that weren't enough, citrus fruits may help you breathe easier. Oranges are rich in the antioxidant beta-cryptoxanthin (the pigment that gives them their brilliant hue). In studies, this compound has been shown to help ward off lung cancer, even in smokers.
HOW TO BUY THEM
Choose smaller, firmer, thinner-skinned oranges that feel heavy for their size. These tend to be the juiciest, sweetest fruit.
See a green patch? As long as the skin is smooth, it's nothing to worry about.
Once you have the fruit home, store them loose at room temp on your counter for about a week. Or put them in the fridge in plain sight. They'll keep there for up to two weeks.

Tastes like: A shot of OJ with a raspberry chaser.
Cool fact: Moros are nicknamed "blood oranges" because of their succulent deep-red pulp.

Cool fact: Clementines are the unwanted love child of an accidental tryst between an orange and a tangerine plant.
