Foods high in FODMAPs-complete guide what to eat and avoid:

What is FODMAP?

Fermentable: Foods fermented in large intestines

Oligosaccharide: Small chain of sugar molecules

Disaccharide: Double sugar molecule

Monosaccharides: a single sugar molecule


Polyols: Sugar alcohols.

Your food has a great impact on your digestive system. According to several studies, there is a strong link between the FODMAP diet and digestive issues including, gas, bloating, stomach pain, diarrhea, and constipation. People with digestive symptoms can get remarkable benefits when they switch towards a low fodmap diet. However, everyone is not sensitive to high FODMAP foods, but people with irritable bowel syndrome get affected very commonly.


List of some common FODMAPs

  • Fructose: It is a simple sugar found in many fruits and vegetables that also makes up the structure of table sugar and most added sugars.
  • Lactose: Carbohydrates present in dairy products.
  • Fructans: It is extremely common and found in foods including grains like wheat, rye, and barley.
  • Galactans: Found in large amounts in legumes.
  • Polyols: Sugar alcohols like xylitol, sorbitol, maltitol, and mannitol. Certain fruits and vegetables including blackberries and lychee. They are also used as sweeteners.


The action of FODMAP foods on your body

A major portion of these carbs passes through your intestine unchanged. They are categorized as dietary fibers and are resistant to digestion. But some carbs including lactose and fructose act as FODMAP foods in certain people. This happens because sensitivity to carbs differs from person to person. These FODMAP foods can contribute to digestive issues like IBS in sensitive people.

After reaching the colon, these FODMAPs get fermented and used as fuel by gut bacteria. The same process happens when you take dietary fibers, they feed gut-friendly bacteria, leading to several health benefits. The main difference between these two processes is that gut-friendly bacteria tend to produce methane whereas the bacteria which feed on FODMAP foods produce hydrogen, leading to bloating, stomach cramps, pain, and constipation (). Most of these symptoms are caused by distention of the gut, which can make your stomach look bigger. In addition to this high FODMAP foods are also osmotically active, so can draw water into your intestine and contribute to diarrhea. 


What is Low FODMAP Diet

  • A temporary diet containing a very low amount of food compounds called FODMAPs is referred to as a low FODMAP diet.
  • This restriction is for 3-8 weeks. Then these food items are re-introduced gradually into a low FODMAP diet one by one.
  • This procedure helps to check which food has caused the GI symptom. 


Stages of a low FODMAP Diet

  • Restriction Stage: In this stage, all the high FODMAP foods are completely restricted. This is done for 3-8 weeks. The period needed for the improvement of symptoms differs from person to person. Once all the symptoms subside, we proceed to stage 2. 
  • Reintroduction Stage: In this stage, high FODMAP foods are re-introduced one by one. The reason behind this is to identify the types of FODMAP you can tolerate. In this stage, your threshold level for various FODMAP is determined. The high FODMAP foods are introduced one by one for 3 days. This stage must be done under the supervision of a professional. This method helps in the elimination of the main culprit. When you come to know what suits you and whatnot, you can proceed towards the next stage. 
  • Personalization Stage: At this stage, you can personalize the diet with the help of a professional. The intolerant food is restricted completely, other foods which can be tolerated are given in small amounts and are adjusted accordingly.
