Low FODMAP diet – elimination phase

FODMAP diet – very fashionable, but above all helpful for people with irritable bowel syndrome. Who is it recommended for? What should be avoided during the elimination phase and what is the phase at all? You will find the answer in the following article for these and many other questions. I invite you to read.


For who low FODMAP diet?


This diet can be extremely helpful for people diagnosed with irritable bowel syndrome. The benefits of its use can also be applied to athletes who suffer from gastrointestinal discomforts or training in sports competitions, but this is a topic for a separate article. Symptoms of IBS often coincide with the symptoms of other more serious diseases such as gut cancer, so before the doctor diagnoses IBS must first rule out all other diseases. Only then can you work towards reducing the symptoms of irritable bowel syndrome and here the low FODMAP diet comes in for help.


The FODMAP dietary phases


The low FODMAP diet consists of 3 stages. The first is the phase of elimination, the second reintroduction, the third is the implementation of acquired knowledge in life, i.e. planning the menu so that the intestines are “happy and calm”. Each of the stages requires a detailed discussion, which is why in this article I would like to discuss the subject of Phase I. In the following I will discuss the next stages of the diet.


Phase I – elimination of high FODMAP products

It is a rest time for the intestines. For 4-8 weeks (because this is how long this phase lasts) you should exclude from the diet all products that may potentially increase the symptoms of IBS. Thanks to this, the intestines as well as the mind relax. People with IBS at the time feel much better. They leave the fear of ailments that usually meet them after eating a meal. This time is the preparation for Phase II, where high FODMAP products are introduced in turn.

During the first phase of the diet you need to eliminate a number of products, which is a high risk of food deficiency. That is why it is extremely important to follow it under the supervision of a nutritionist. Thanks to this, the risk of possible deficiencies of vitamins or minerals will be reduced to a minimum.

Like any elimination diet phase FODMAP diet can not be permanent. It should last four weeks. If the improvement of well-being does not occur, i.e. intestinal problems will continue, it should be extended to 8 weeks, but not longer.

What should be avoided?

In the low FODMAP diet you should avoid products that contain large amounts of monosaccharides (fructose), disaccharides (lactose), oligosaccharides (fructans, fructooligosaccharides, i.e. FOS and galactooligosaccharides, i.e. GOS), and polyols.

What foods can we find large amounts of these ingredients in? For simplicity, I will save them using the division into food groups.
