Rheumatoid arthritis is a chronic disease, and patients’ appetite and digestive function are often affected by joint pain, reduced activity, and years of medication. Food is the main source of nutrition and energy needed in daily life. If the nutrition and energy of the patient’s diet cannot meet the needs of the body, then not only will the drugs taken fail to treat the disease, but also the disease will deteriorate further. Therefore, diet is also very important for rheumatoid arthritis patients. Because the disease is in a long period of chronic consumption, therefore, first of all, we should pay attention to the selection of high protein, high vitamin and easy to digest food, after reasonable nutrition and appropriate cooking, to maintain good color and flavor, as far as possible to improve the patient’s appetite. It is necessary to eat richly to ensure comprehensive and reasonable nutrition. To date, there is no sufficient evidence that diet therapy can transform the course of rheumatoid arthritis, so it is incorrect to apply diet therapy alone. Diet therapy should only be used as an adjunct to relieve the patient’s symptoms. The possible reasons for the improvement of joint symptoms in patients with diet therapy are multiple, and the efficacy may be the result of a combination of factors. Patients with rheumatoid arthritis have long disease duration and often take medication throughout the year, so the spleen and stomach are often affected to a certain extent. For example, if the body belongs to the internal heat, should not take red ginseng, deer antler, for hot food, such as garlic, green onions, leeks, chili peppers, etc. should not eat; spleen and stomach weak transport weakness, should not take gum, silver fungus and other supplements, food hard, cold and fruit in the raw pear should be eaten less; stomach acid or full stomach and abdomen, should not eat more sweet and greasy things. Rheumatoid arthritis patients, the body’s immune status is in a state of disorder, often to some drugs or food than normal people are more prone to allergies, so some patients can even clearly say which food to eat after the joint pain will be significantly aggravated. If you have eaten foods that have significantly triggered the onset of arthritis in the past, you should “abstain” from eating these foods. Other than that, all other foods can be eaten, and fresh vegetables and fruits should not be missing. Of course, rheumatoid arthritis patients should not eat too much fatty food, as well as too acidic, too salty food; because of the hot nature of wine to help fire, should be used sparingly or not.
