3. Tart Cherry Juice
Juice is usually discouraged for people with joint pain because it contains a lot of sugar. Sugar is inflammatory and juice contains no fiber to moderate the release of sugar into your bloodstream. Whole fruit is typically okay, because it contains a good amount fiber along with its sweetness.
An exception to the no-juice rule, however, is tart cherry juice. Studies have shown that it can reduce inflammation and swelling, thereby relieving symptoms of osteoarthritis.
