The most common cause of joint pain is arthritis. Arthritis is an inflammatory condition that affects your joints, with the two most common types of arthritis being osteoarthritis (OA) and rheumatoid arthritis (RA).
Osteoarthritis occurs when the cartilage at the ends of your bones wears down. This protective tissue is crucial for your joints' healthy movement and flexibility. However, when it wears down, many people begin to experience issues like chronic pain, swelling, tenderness, and stiffness. As a result, you may not be able to engage in normal activities, and the downstream effect can impact physical fitness and mobility.
This joint condition is primarily caused by wear and tear over time and affects millions worldwide. Although OA can impact any joint, the most commonly affected areas are the hands, knees, hips, and spine (2).
Rheumatoid arthritis, on the other hand, is an autoimmune disease. In RA, your immune system attacks your own tissues and affects the lining of your joints. Ultimately, RA can lead to bone erosion and joint deformities over time if left untreated. Although less common than OA, RA is estimated to affect about 1% of the population (3).
Whether you're dealing with wear and tear or are experiencing joint pain due to RA, diet can go a long way in easing symptoms of these joint conditions. While some foods can ease the discomfort of joint pain, others work by enhancing the health and integrity of the joint itself. Below are seven foods that support joint health and longevity.
