What is a Low Fodmap Diet?


According to the NCHS, 28.3 million Americans visit physicians with digestive complains every year. This shows you how common digestive issues are. Nutrition experts are blaming the diet for digestive problems such as constipation, diarrhea, bloating, gas, and stomach pain. Many also specifically blame FODMAPs for such issues. FODMAPs are compounds that are found in certains foods such as barley and wheat. They are known to trigger irritable bowel syndrome and various other GI disorders. Here’s where the low FODMAP diet comes into play.

This diet focuses on reducing the intake of FODMAPs to reduce stomach issues. Let’s get to know more about FODMAPs and a low FODMAP diet.

What Are FODMAPs?

FODMAPs, short for Fermentable, Oligo, Di, Monosaccharides and Polyols, can cause a lot of problems in the digestive system. These are carbohydrates which are hard to digest since they can end up on the far end of the intestine where the gut bacteria is present.

Once these carbs reach near the bacteria, it uses them as fuel and create hydrogen gas giving rise to many kinds of digestive disorders. Other than that, FODMAPs are also known to create liquids in the intestine that can cause diarrhea.

Here are some common types of FODMAPS:

  • Lactose: This FODMAP is found in dairy products such as milk. 
  • Fructans: Can be found in many foods but mostly in grains such as wheat, spelt rye etc.
  • Fructose: This FODMAP is present in most of the fruits, vegetables and added sugars.
  • Galactans: Found in legumes.
  • Polyols: They are sometimes used as sweeteners and are often found in many fruits as well.

What Is a Low FODMAP Diet?

A diet that limits the consumption of foods that contain higher amount of FODMAPs in them is a low FODMAP diet. This diet doesn’t exclude FODMAPs right away but gradually because eliminating them right away can cause many problems in the body.

Once you reduce the consumption of FODMAPs, you will see a noticeable change in your stomach issues and even feel lighter.
