Fructans and FODMAPs: What You Need to Know About Digestive Discomfort

Fructans are a type of carbohydrate that can be hard for some people to digest. They belong to a group of small-chain sugars called FODMAPs, which may cause discomfort in those with intolerances. Despite this, foods containing fructans remain a healthy part of most diets unless an intolerance exists. Wheat and onions are the primary sources of fructans in many diets. Other high-fructan foods include barley, rye, spelt, bananas, dates, grapefruit, and various vegetables and nuts. For individuals with fructan intolerance, symptoms like bloating, diarrhoea, gas, and stomach pain can occur after consumption.

The low-FODMAP diet is designed to diagnose such intolerances. It involves removing high-FODMAP foods and then slowly reintroducing them to assess tolerance levels. Keeping a detailed food log can help identify specific triggers. Working with a dietitian is recommended to ensure balanced nutrition during this process. Avoiding fructans is unnecessary for most people, as they contribute to a healthy diet. For those with intolerance, the low-FODMAP diet provides a structured way to manage symptoms and identify problematic foods. Proper guidance helps maintain nutritional needs while addressing digestive issues.
