Irritable Bowel Syndrome Message Boards | Re: Fructose Malabsorption Question from Honey

An important thing to remember is that only foods containing more fructose than glucose are a problem. Furthermore while some people are sensitive to small amounts of excess fructose others can tolerate quite large amounts. When the amounts get too high everyone has problems.

I believe the article in the 'Additional Tips' section says "Brown rice has more fructose than white rice". This is not particularly important because neither contains much fructose (< 0.1 grams /100 grams). The really important part of the section is the last sentence.

Some squash are higher in excess fructose than others. On average they have about 1.5 grams of excess fructose per 100 grams. This can vary significantly from variety to variety. I can eat zucchini and little bits of one or two other types. However, I believe it is the insoluble fiber not the fructose in the squash that is a problem for me. You will have to experiment to figure it out for yourself because there isn't good data available.
