FODMAPs stand for “Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols.” When you eat these compounds found in many foods, you are basically asking for your belly to bloat and be uncomfortable. Foods that contain FODMAPs will be fermented by bacteria in your gut, causing those unpleasant symptoms.
What to do?! Okay, lets be real. DO NOT ELIMINATE EVERYTHING! That takes out the element of joy in eating out, relaxing, and having things you love. Taking all yummy things out is not the answer. However, sometimes our bodies are not able to digest certain things. One way to find out what is upsetting your stomach is to begin with testing certain foods that you feel you may have too much of. By testing, I mean taking them out for a bit to see if that specific food is the culprit. It is all about trial and error. (If it is not any of the FODMAP foods, then maybe it would be smart to seek some external help from a natural doctor of some sort).
Below is an illustration I found on http://blog.katescarlata.com/. It will give you a list of FODMAP containing foods. This can help you assess your diet to see if you have a wee bit too much of something in particular on a regular basis!
