Patients with rheumatoid fever should avoid the following three major categories of foods: The first category is vegetables, such as celery, coriander, leeks, seaweed, and mushrooms, which should be consumed in moderation. The second category includes meats like lamb, beef, and dog meat, which are very warming and nourishing and should be reduced in consumption. The third category includes seafood such as shrimp, crab, and sea cucumber, which are high in protein and should also be avoided. For patients with rheumatism, the general dietary principle is to follow a light diet, avoid spicy and dry-heat foods, and reduce greasy foods. For patients with rheumatic fever, it is particularly important during the acute phase to rest and avoid catching colds and infections.
