Oranges
British researchers who analyzed the diets of 25,000 people found that those who ate foods with a chemical common in oranges and other orange-colored fruits, like apricots and nectarines, were less likely to have painful inflammatory joint conditions. Just one or two daily servings of these fruits made a difference.
Green and black tea
Tea is rich in antioxidants called flavonoids, which may protect against cell damage that can worsen conditions such as arthritis. It also contains a chemical that fights inflammation, so consider swapping that morning cup of coffee for a green tea instead.
