Licorice and ibs

Licorice and IBS

Right now, licorice is found in everything from brownies, candy, and ice cream to dishes with fish, shellfish, chicken, and lamb. Licorice is indeed both delicious and trendy. The question is, though, how does your stomach handle it, and how does licorice and IBS fit together, particularly in relation to FODMAP? You’ll find out here!

What is licorice?

Licorice is a substance derived from the root of Glycyrrhiza glabra. Licorice root contains the glycoside glycyrrhizin, which gives it a sweet flavor, and this is what we refer to as sweet licorice. Salt licorice, on the other hand, is something entirely different.

Different kinds of licorice - how do they work with IBS?

Licorice root is used in some teas. Unfortunately, this type of tea has been analyzed and found to contain high levels of oligosaccharides. Although sweet licorice, which is also made from licorice root, is generally acceptable, licorice root itself is not recommended in products like tea. On the other hand, salmiak or ammonium chloride used in salt licorice is considered okay. However, some licorice products contain wheat flour, which makes them red in the FODMAP context. This will be indicated on the ingredient list.

Licorice to help the stomach is a myth

Licorice root was once a medicinal plant. It has been used for digestive support for thousands of years and was sold at pharmacies until the 1970s. Researchers have found that licorice root can indeed help heal stomach ulcers. However, it is not used as a treatment today, and given the increasing number of people with sensitive stomachs, recommending licorice for digestive issues might not be the best advice.

Who should not eat licorice?

Consuming more than 50 grams of licorice per day can cause harmful effects in sensitive individuals. This is because glycyrrhizin inhibits an enzyme that converts cortisol to cortisone. People who are sensitive and consume licorice frequently may experience potassium deficiency, high blood pressure, and changes in the levels of hormones that regulate salt balance. While adverse effects are not particularly common, in Sweden for example, there are about 10 cases of licorice poisoning each year.
