5-Day Effective Low-FODMAP Workweek Diet Plan for IBS

The Tummy Clinic | July 24th, 2023

Irritable bowel syndrome (IBS) is estimated to affect up to one in five Canadians. It often starts in young adulthood and occurs more frequently in women than men. IBS symptoms include cramping, abdominal pain, bloating, gas, and diarrhoea or constipation, or both. IBS is a chronic condition characterized as a Gut to Brain to Microbiome communication disorder that needs to be managed long term. Most people can control their symptoms by following a targeted irritable bowel syndrome diet and managing their lifestyle and stress. More severe symptoms need medication and counselling.

Low-FODMAP Diet Plan for IBS

A low-FODMAP diet is often recommended by doctors to reduce symptoms of IBS. However, it should be noted that the low FODMAP should only be followed according to the researched informed 3 steps. Step 1: low FODMAP (2-4 weeks), Step 2: Reintroduction, Step 3: Personalization. So, what are FODMAPs, in the first place? FODMAP is an acronym that stands for “fermentable oligosaccharides, disaccharides, monosaccharides, and polyols.”

FODMAP refers to a group of small carbohydrates (sugars and fibres) that are not properly absorbed in the gut. These poorly digested sugars can draw water into the small intestine and become food for the gut microbes that live in our colon. This results in gas, which, along with water, can be trapped in the intestine or stretch the intestine.

Different foods have different FODMAP levels. A low-FODMAP diet reduces or even removes foods that are high in FODMAPs and promotes eating foods that are low in FODMAPs for 2-4 weeks until a well-planned reintroduction can occur. The goal is to discover triggering foods to symptoms. Some scientific evidence shows that a personalized low FODMAP for IBS may improve IBS symptoms thus improving quality of life for sufferers.

When it comes to creating a low FODMAP diet for IBS, a low-FODMAP trained dietician would help tailor a balanced low-FODMAP diet plan suited to your condition. This would ensure your meal planning is nutritionally adequate and also minimize any unwanted symptoms from FODMAPs.
