When experiencing diarrhea it is best to stick with non-irritating foods that are gentle on the stomach. Include in your diet those that are salty, starchy and low in fiber.

Recommended foods

Helps replace potassium lost due to diarrhea and firm bowel movements.

Rice / plain pasta / tapioca / boiled potatoes
Rice should be served without added spices or fat (mayonnaise, butter, cream, etc) since they may prolong frequent or watery bowel movements.

Applesauce or whole apples are a great source of pectin, a natural bulking agent.

Green tea or weak black tea, preferably decaffeinated, helps to replace lost fluids. Try to stick with decaffeinated tea and don’t use herbal teas, which might prolong diarrhea. Skip additives to your tea like milk, honey, sugar or sugar substitutes.

Toast / salted crackers / soda crackers
White or wheat toast should be served without added butter.
