I empathize with you and your diet as prior to becoming aware of FODMAP's, I was essentially following the IBS diet eating more or less everything you've mentioned. Unfortunately though if it turns out that if I have issues with fructose, I was eating some major culprits like wheat and honey. I did catch the part in the article you linked about the relationship between fructose and glucose so I'll also avoid fructose rich fruit like apples of which I was eating in sauce form and stick to bananas and oranges.
I'm a little confused still about when it comes to vegetables though. Should their fructose level and whether or not they are a soluble or insoluble fiber be cross referenced. For example, a baked potato which is deemed O.K by Eating for IBS has a fructose level around 700 http://www.nutritiondata.com/foods-011011000000000000000-3.html? Is that high...too high?
Also, unfortunately whether it's in the name of soluble or insoluble fiber as with the eating for IBS approach and galactons, most vegetables and legumes are out of the question. Like you, I go with rice and potatoes. When you say you eat pasta can I assume you mean rice pasta?
Anyway I could go on but it's just more of the same stuff and until I see a dietitian I won't really know anyway. Thanks for the links as they are an invaluable source of information.
