All suggested serving sizes are high in FODMAPs, so please be aware that a meal high in fermentable carbohydrates may cause digestive discomfort. However, it is important to perform a custom challenge using a portion size that you would normally eat, so it reflects your regular diet as much as possible.
How to do a FODMAP at-home test?
