You can find out more about how to maintain a healthy diet even with fructose malabsorption in our article "A healthy diet despite fructose malabsorption".
Many vegetable varieties can be made more tolerable by cooking them thoroughly, pouring off the cooking water and rinsing the vegetables well. The fructose content can be reduced a little by doing this.
The following is a limited list. You can find a more precise list of fructose levels in foods in our fructose table.
You can find detailed lists with fructose levels in the download area and here in our list of foods.
If a corresponding molecule of glucose is available for every molecule of fructose, it is no problem for the digestion (see "Treatment of fructose malabsorption”), as long as you don't ingest too much fructose all at once! It thus all depends on the glucose-fructose ratio (after the fructose-restricted diet!) Note!: Glucose (dextrose) should never be eaten in large amounts or over a long period of time, because it will put a strain on the blood sugar levels and therefore also on the pancreas.
