Fructans are a type of carbohydrate, composed of linked units that form chains. They appear in a variety of foods-wheat, onions, garlic and even some fruits. Unlike gluten, which is a protein, fructans are fibers that largely pass through the small intestine untouched. When they finally reach the colon, gut bacteria ferment them, releasing gases such as hydrogen and methane along with short‑chain fatty acids
