Patients with systemic lupus erythematosus nephritis can eat leeks, which are rich in fiber but low in sodium and protein, and thus will not have much effect on patients with kidney disease, especially lupus nephritis. However, because leeks are difficult to digest and can irritate the gastrointestinal tract to some extent, the amount eaten should not be too large. From the point of view of Chinese medicine, leek is a spicy and stimulating food, which is a hair product and is not conducive to the control of inflammation in the body, so patients with systemic lupus erythematosus nephritis can eat leek, but they should eat it as little as possible.
