Generally speaking, patients with rheumatoid arthritis and osteoarthritis do not need to control their diet as strictly as those with gouty arthritis, but there are studies suggesting that changing the structure of the diet can improve the symptoms of arthritis. Specific recommendations are as follows: (1) Promote a balanced diet with foods high in protein, vitamins and easy to digest to ensure complete and reasonable nutrition. (2) If there is a clear allergic reaction to a certain food, or induce aggravation of arthritis symptoms, such as individual patients may have worsened joint pain after drinking milk, then avoid eating it again. (3) Rheumatoid arthritis is easily combined with osteoporosis, so you should eat more calcium-rich foods and take calcium supplements if necessary. (4) Avoid fatty, spicy, acidic and salty foods. (5) For women with osteoarthritis, losing more than 3.5 kg can reduce the chance of joint pain attacks by 50%. (6) Eat foods rich in ? -3 fatty acids, such as fresh frozen fish, sardine oil, flaxseed, green beans, tofu and olive oil, may reduce joint symptoms. (7) Do not let food taboos affect the nutritional status of your body. A healthy lifestyle and taking medications as prescribed by your doctor are the keys to treating arthritis. (8) Other foods that are good for arthritis include cruciferous vegetables such as broccoli, foods rich in vitamin D such as mushrooms, vitamin C foods such as ginger and kiwi, anthocyanins such as grapes, and beta-cryptoxanthin foods such as papaya, which can be consumed according to your taste.
