Can you eat red bean paste buns when you have diarrhea?

Diarrhea patients should generally avoid eating red-bean-paste buns.

Diarrhea is commonly caused by ingestion of contaminated food or concurrent bacterial or viral infections, and is often accompanied by abnormal symptoms such as abdominal pain. Red-bean-paste buns contain legumes (e.g., red beans), which may cause intestinal gas and bloating after consumption; this can exacerbate symptoms including abdominal distension, diarrhea, and even abdominal pain—thus their intake is not recommended. Patients should also avoid other gas-producing foods, such as radishes. Once diarrhea symptoms have significantly improved, these foods may be gradually reintroduced in moderation, typically without adverse effects.

After onset of diarrhea, patients are advised to visit a hospital for diagnostic tests, including stool culture, routine stool examination, complete blood count (CBC), C-reactive protein (CRP), and serum electrolyte assays, to help assess and confirm the underlying cause. If diarrhea results from a viral infection, symptomatic treatment with antidiarrheal agents—such as smectite powder—may be prescribed per physician guidance. If caused by bacterial infection, broad-spectrum antibiotics (e.g., levofloxacin) combined with antidiarrheal therapy may be indicated.
