When you type "diet" into Amazon.com's book search, you get 81,000 titles! So we understand why you might be a bit wary of one more healthy-eating plan.

But we've got new nutritional information about an anti-osteoarthritis dietary strategy that you're going to love, because in addition to protecting bone-cushioning cartilage in your joints, it will help prevent cancer, diabetes, gastro distress and heart disease, plus protect your liver.

A study found that eating broccoli can protect your joints from "wear and tear" osteoarthritis. Steamed, pureed, oven-roasted - even raw - this cruciferous vegetable delivers two bioactive chemicals: sulforaphane and indole-3-carbinol. The sulforaphane seems particularly joint-friendly and, when teamed with its partner, it helps every system in your body. This powerhouse duo also is found in broccoli sprouts (20 times the content), Brussels sprouts, cauliflower, Savoy cabbage, red cabbage, kohlrabi, horseradish, kale, arugula and collard greens.

For maximum joint protection, also eat strawberries, blueberries, carrots, olive, walnut and canola oils, and fish with omega-3 DHA. We also suggest 900 mg daily of an algal oil DHA supplement.
