FODMAPsare a group of sugars (types of carbohydrates) that are not completely absorbed in the gut.

What Happens When You Eat FODMAPs?

As FODMAPs slowly move through the digestive tract, they attract water.

Karina Tolentino, RD

When they reach thelarge intestine(colon), bacteria ferment the FODMAPs, producing gas as a byproduct.

The extra water and gas can push on the intestinal wall, expanding and stretching the large intestine.

Most people dont experience noticeable symptoms when this happens.

Symptoms include:

Whats the Low-FODMAP Diet?

Thelow-FODMAP dietis an eating plan that reduces the amount of foods you eat that contain FODMAPs.

People with IBS often follow it to help reduce or resolve their symptoms.

It has been shown to help improve symptoms in 75% of people with IBS.

Why Are FODMAPs Difficult to Digest?

FODMAPs are a throw in of fermentable short-chain carbohydrate that are resistant to digestion in thesmall intestine.

The chains in the carbohydrates cannot be broken down and absorbed in the small intestine.

When these undigested carbohydrates reach the large intestine, they act as asource of foodfor gut bacteria.

These bacteria feed off the short-chain carbohydrates and end up producing gases and fatty acids as byproducts.

Are FODMAPs Bad for Everyone?

The short answer is no.

Most people are able to consume FODMAPs without any symptoms.

Our digestive systems are designed to process nondigestible carbohydrates and fibers in a certain way.

Who May Benefit From a Low-FODMAP Diet?

The low-FODMAP diet is designed for people withmedically diagnosed IBS.

They can guide you in finding the right solution for your health problems.

It is best to have support and guidance when following this diet instead of trying to tackle it alone.

This allows you to be more confident about what you eat without being afraid it will cause symptoms.

Common Foods High in FODMAPs to Avoid

FODMAPs are found in many different foods and beverages.

Seek out a FODMAP-trained registered dietitian or gastrointestinal (GI) specialist beforestarting a low-FODMAP diet.

If you are at risk of disordered eating, the low-FODMAP diet might not be right for you.

Phase one requires eliminating all major FODMAP triggers from your diet.

This phase is recommended to last two to six weeks.

This is to allow your symptoms to decrease andsee if decreasing FODMAPs will help youmanage your IBS.

The length of this phase can vary but generally lasts around eight weeks.

Be sure to keep afood diaryto record what you ate, how much, and any resulting symptoms.

This process continues until you have tested each FODMAP category.

A low-FODMAP diet is not for everyone.

Most people can consume FODMAPs without any symptoms.

A low-FODMAP diet can reduce symptoms and improve quality of life.

However, it is important to consult a healthcare professional before beginning one.
