What Foods Should You Avoid During Diarrhea? During episodes of diarrhea, certain foods can worsen symptoms and delay recovery. Avoid spicy foods, fried items, and high-fat meals, as they irritate the digestive tract. Dairy products may aggravate lactose intolerance, even temporarily. Limit sugary foods, artificial sweeteners, caffeine, and alcohol, which can increase stool frequency. Raw vegetables, whole grains, and legumes are high in insoluble fiber and may intensify cramping. Acidic fruits and juices can also irritate the gut. Focus on bland options instead.
