Like lactose, fructose is a type of sugar that can be difficult to digest. Fructose is most commonly found in fruit, but is also in honey, some vegetables and grains. Fructose intolerance occurs when the molecule that transports fructose in our digestive system doesn’t work properly. The fructose can’t be absorbed in the small intestine, so when it reaches the colon the bacteria there have a field day. These bacteria ferment the fructose, and this causes bloating, wind, pains and diarrhoea.
Diagnosis of suspected fructose intolerance can be done via a breath test, very similar to lactose testing. A liquid fructose solution is consumed by the patient, and the amount of gas released on the breath is measured over the next few hours. The results determine diagnosis.
If you are found to have a fructose malabsorption issue, it is strongly advised that you avoid any foods that are known to be high in fructose, or those foods that contain fructans, which are chains of fructose joined together. Reducing your fructose load will reduce your symptoms. Over time you may find that you can still tolerate certain foods that contain fructose, especially those low in the sugar.
