Lupus patients can eat seafood in moderation as long as they are not allergic to seafood. Lupus erythematosus is a connective tissue disease with butterfly-shaped erythema on the face as a typical symptom, which can be accompanied by systemic damage. Lupus erythematosus patients should pay attention to their diets and try to choose diets rich in high-quality proteins, high vitamins, low-fat, low-sugar and low-salt diets, such as milk, eggs, fruits, etc., and at the same time, they should avoid the foods that may induce or aggravate the lupus erythematosus disease. However, a few SLE patients may be allergic to seafood, which may aggravate skin symptoms after eating seafood; or some SLE patients may be combined with renal lesions and elevated blood uric acid, which may lead to joint swelling and pain after eating seafood. SLE patients with these phenomena are not recommended to eat seafood. Lupus patients can obtain professional dietary advice from the rheumatology and immunology department, nutrition department and other related departments in regular hospitals.
