Red Bell Peppers
A bell pepper has twice the vitamin C of an orange, and C is one of the nutrients most responsible for the health of collagen (connective tissue that aids in joint flexibility). Bonus: Red bell peppers also contain beta-cryptoxanthin, a compound that helps reduce pain.
The bright orange color comes from beta-carotene, a strong antioxidant that fights the cell-damaging molecules called free radicals released by your body.
Studies have shown that the mustard-yellow spice, which contains an anti-swelling compound called curcumin, may help relieve aches by lowering inflammatory chemicals circulating in the body.
