I need a deeper explanation of this whole soluble/insoluble fiber thing and why the foods on Heather's safe list are considered safe. The whole soluble vs. insoluble fiber thing sounds logical and the rule about what can be more easily mashed does make sense. But I've just checked a lot of stuff from the safe list on:
http://www.fineli.fi/index.php?lang=en
where you can get information about the fiber content of many different foods. Out of the things I tried, like rice, potatoes, carrots, oatmeal, oatmilk, mango, I think only oatmeal boiled with water had more soluble fiber than insoluble. Potatoes, boiled with salt, were listed as having 100% INSOLUBLE fiber!!! It would have been ok if the safe foods just contain relatively much soluble fiber (though not necessarily more SF than IF) but the potato fiber content makes even that explanation impossible. So now I am really, really, really confused. 
I know about the organizations behind the webpage and they are serious so why would their information be wrong? Heather can't be the only one who has the correct information on this. That would be very strange.
The insoluble fibers are specified to be water insoluble but I'm guessing that is what Heather is talking about. Is the soluble fiber the true reason why this diet works or is it that the stuff on the safe list are just easy on the bowels for some (partially different) reason?
I'm not saying Heather's rules don't work - obviously they do - and they agree in a big part with what I had figured out myself before I found Heather's webpage. And I don't mean to criticize Heather's information - not at all. I just think it would be good to get the rules and the reasons why the foods that are more likely to work, work, clarified as that would help us all make informed decisions about what we should eat.
Thanks,
