Rheumatoid arthritis is an autoimmune disease and such patients should be careful to avoid smoking and alcohol in their daily lives, especially if they are receiving treatment measures such as medication; foods such as dairy, peanuts, chocolate and cheese should be eaten sparingly, but generally do not need to be strictly avoided; fatty meats and various sweet foods should also be restricted to avoid worsening joint discomfort.
It is important to note that daily diet can have a positive effect on the control of the disease, but it is not a substitute for treatment and may vary from patient to patient. Your doctor will be able to formulate an appropriate treatment plan and give you reasonable dietary advice based on your actual condition.
