Fruits with a high fructose content can be rendered safe for people with fructose malabsorption by cooking the fruit with dextrose. Dextrose acts as a counteracting agent for fructose. I would recommend dextrose supplements for all individuals suffering from fructose malabsorption, just incase you end up eating some fruit and vegies outside of your normal diet. During the cooking process the excess fructose in the fruit bonds with the dextrose monohydrate, creating a sugar molecule (sucrose) which still tastes sweet but which will not provoke symptoms in an individual who suffers from a fructose malabsorption.
