Patients with rheumatoid arthritis can drink red bean and coix seed beverage, which does not significantly affect the condition and is rich in proteins, potentially aiding in recovery. Rheumatoid arthritis is a common rheumatic disease, related to infections by streptococci. With the widespread use of penicillin in recent years, the incidence of rheumatoid arthritis has been decreasing. Currently, it is mainly seen in patients with recurrent streptococcal infections, such as those who frequently suffer from tonsillitis, which increases their likelihood of developing rheumatoid arthritis. Patients with rheumatoid arthritis should maintain a light diet and can appropriately consume more high-quality protein foods, such as lean meat, milk, and eggs, while avoiding or reducing spicy and stimulating foods.
