Patients with rheumatic fever can eat freshwater fish, but should try to eat less fish without scales and sea fish. For patients with rheumatic fever, the general dietary rule is to eat a light diet and reduce consumption of spicy, warming, oily, and rich foods. Foods such as celery, coriander, leeks, seaweed, mushrooms, beef, mutton, dog meat, and longan should be minimized. Seafood, such as shrimp and crab, which are high in protein, should also be consumed less. In addition to dietary considerations, patients with rheumatic fever should also avoid getting cold and pay attention to rest.
