Say "C" to Stave off Arthritis

Eating vitamin C-rich foods may protect your knees from osteoarthritis, reports a recent study in Arthritis Research & Therapy. Here's why: They're packed with antioxidants, which protect cells from oxidative damage, and oxidative damage breaks down cartilage, the "shock absorber" in the knee joint. Vitamin C slows down deterioration by strengthening cartilage and reducing inflammation in the joint. "To get the full benefits, eat food with lots of vitamin C on a daily basis," says Marissa Lippert, MS, a dietitian in New York City. But oranges have stolen the vitamin C spotlight for far too long. Here's how to sneak the top five runner-ups into your diet:

1. Papaya


2. Red, Yellow, and Orange Bell Peppers


3. Broccoli


4. Brussel Sprouts


5. Strawberries
