Status: Not recommended
Onion is classified as not recommended for IBS based on current dietary assessments. Fruits and vegetables provide fibre, vitamins and phytonutrients, and are a core component of many balanced dietary approaches. With IBS, individuals react very differently to specific foods; the FODMAP approach, which focuses on fermentable carbohydrates, is widely used. The reasoning given is: high FODMAP content. The assessment is supported by a broad evidence base.
