Best foods: Saltine crackers or pretzels can help, says Dr. Lee, as does small quantities of dry toast or cereal. Ginger or lemon tea, fresh or frozen lemon slices, and peppermint also work. Worst foods: Greasy, spicy, or oily foods, caffeine, alcohol, and carbonated drinks can make nausea worse.
What to eat if you have diarrhea: Eat foods that are high in pectin, such as applesauce, bananas, and yogurt. Pectin, a water-soluble fiber, helps reduce diarrhea. Eat foods that have a lot of potassium, such as fruit juices, sports drinks, potatoes without the skin, and bananas. Potassium is often lost through diarrhea. Eat foods that are high in sodium, such as soups, broths, sports drinks, crackers, and pretzels. Salt helps you retain water so you don't become dehydrated.
