Food choices play a direct role in managing arthritis. A diet built to reduce inflammation and support a healthy weight may also help slow bone loss and reduce fracture risk. These dietary factors affect arthritis symptoms, and specific eating patterns have been studied for their effects on inflammation and joint health.
Managing Arthritis With Diet
A plant-based diet benefits people with arthritis. It includes fruits, vegetables, whole grains, low-fat dairy, and lean proteins, and these foods provide vitamins, minerals, fiber, and phytochemicals associated with reduced inflammation. Fruits and vegetables are naturally low in calories and sodium. When medication causes fluid retention or weight gain, these foods provide options that support a healthy diet.
Eating Anti-Inflammatory Nutrients
Certain fats and nutrients may reduce joint pain, inflammation and tenderness in people with rheumatoid arthritis. Omega-3 fatty acids appear in cold-water fish such as tuna, salmon, mackerel and herring. Plant sources include walnuts, chia seeds, ground flaxseed and soy foods such as tofu and edamame, and these unsaturated fats appear to modify the inflammatory process. Extra virgin olive oil contains no omega-3s, but it has anti-inflammatory properties that may provide additional benefit when included in a healthy diet.
Antioxidants may help protect cells from damage. They appear to slow oxidation, a process linked to inflammatory arthritis, and colorful produce tends to contain high levels of these compounds. Common antioxidants include vitamins C and E, carotene, lycopene and flavonoids. A varied diet provides many of these substances, and several foods contain particularly high levels.
- Spinach, kale and beets
- Blueberries and cherries
- Beans, nuts and green tea
- Ginger root and turmeric powder
Dietary fiber is found mainly in fruits, vegetables, whole grains and legumes. It passes through the digestive system relatively intact, and it feeds bacteria in the digestive tract that improve their diversity and balance. A healthier gut has been shown to help reduce inflammation in people with arthritis. High-fiber diets also support weight control, while they lower the risk of diabetes and heart disease.
Following Special Diets
Research into specific eating patterns has focused largely on rheumatoid arthritis. Several studies found that a vegan diet followed for as little as three weeks was associated with lower C-reactive protein levels. Some research on gluten-free vegan diets also reported reduced symptoms, but scientists have not established whether those effects result from avoiding gluten, following a vegan diet, or other factors.
Studies suggest the Mediterranean diet helps curb inflammation. It emphasizes vegetables, fruits, whole grains, nuts, fish, legumes, and oils such as olive oil; it limits red meat and processed food. Research indicates this pattern may relieve joint pain and stiffness. Intermittent fasting has also been studied for its effect on inflammation, but it carries side effects and is not appropriate for everyone.
Supporting Weight and Bone Health
Excess weight places added stress on weight-bearing joints. It aggravates pain, stiffness and inflammation in joints such as the knees, and a healthy weight reduces that physical load. Most plant foods are low in calories; a plant-based diet supports weight control. People with inflammatory arthritis or connective tissue disease face a higher risk of osteoporosis. Corticosteroid medications raise that risk further, and adequate calcium and vitamin D intake may help slow bone loss. Low-fat dairy products provide both nutrients, which may also reduce the risk of fracture.
Medical care works alongside dietary changes when arthritis symptoms persist. Conservative, noninvasive methods come first; a physician may recommend medications such as counterirritants or disease-modifying antirheumatic drugs. Patients whose pain continues might benefit from corticosteroid or hyaluronic acid injections, which are minimally invasive treatments that ease inflammation and encourage joint movement. Surgical intervention remains an option in severe cases.
Talk With a Healthcare Professional
A registered dietitian or physician can guide dietary changes. Special diets and food restrictions can create nutritional concerns, and professional guidance helps address those needs. Dietary changes work alongside medical treatment, while ongoing care addresses arthritis symptoms and joint health. Talk with a professional to learn more.
