Suggestion: Peel one apple, put it in a bowl and steam it until soft. Eat one apple a day. Apple contains pectin, which can adsorb toxins and moisture, and contains tannic acid, which has astringent and antidiarrheal effects. Eating a cooked apple every day can effectively alleviate the symptoms of diarrhea. This is perfect for patients with chronic diarrhea, which can cure diarrhea and supplement nutrition.
