FODMAP Foods

FODMAPs are a group of carbohydrates that some individuals have difficulty digesting. When the digestive system struggles to break them down, these carbohydrates are not properly absorbed. As a result, they draw water into the small intestine, (leading to loose stools), or in the large intestine, they can ferment and subsequently produce gas. This process can cause various uncomfortable symptoms, including abdominal pain, bloating, diarrhea, constipation, and flatulence—common indicators of conditions like irritable bowel syndrome (IBS) and small intestinal bacterial overgrowth (SIBO).

If you’re experiencing these symptoms or aiming to manage IBS or SIBO, a low FODMAP diet often provides significant symptom relief. However, if you’ve been following a strict low FODMAP diet for 2 to 4 weeks without noticeable improvement, it’s likely that FODMAPs are not the root cause of your symptoms. In such cases, consult your healthcare practitioner for further guidance and appropriate next steps.

Why is it generally not recommended to stay on a low FODMAP diet indefinitely? There are several reasons. One key factor is that many FODMAP-rich foods help promote the growth of beneficial bacteria in your gut—a process known as the "prebiotic effect." Long-term restriction of prebiotic fibres may not be ideal for maintaining a healthy gut microbiome.
