10. Red Peppers
Red peppers are especially good for knee pain because they contain a high amount of vitamin C. This crucial nutrient supports the production of collagen, which provides structure to joints and connects muscle to bone.
That reduces pain by supporting the tendons, cartilage, and ligaments that cushion the knee joints and keep them in proper alignment. Rather than a direct pain reliever, eating foods high in vitamin C actually improves the condition of your knees.
