Protein bars are a great source of energy and nutrition, especially for those with busy lifestyles. Unfortunately, they also contain a lot of carbohydrates, including FODMAPs, which are difficult to digest and can trigger irritable bowel syndrome (IBS) symptoms.

The low-FODMAP diet was developed to allow IBS sufferers to manage their symptoms. It's a challenging diet to design and maintain, as it requires followers to remove FODMAPs from their diet and then slowly reintroduce them and record their body's reactions.
Although most popular protein bars are high in FODMAPs, some aren't and are safe for IBS sufferers.
