That is a bit insulting. How is IBS or indeed FODMAP sensitivity a pseudo-disease?
And FYI I don't think you can be constipated if you eat white bread and not wholemeal bread... (Do wonder what your definition of constipation is then... And you seem to think you are an expert yet think that onions are problematic for fructose malabsorption sufferers just because they contain fructose, that's v helpful.. (not) but totally misleading..)
And how many people did you find that said that psyllium didn't work for them? In case you didn't read my post closely enough, for me it does/would work, most things with excess SF as opposed to IF do (but I wouldn't experiment with wholegrains as grains are different from vegetables) but anyhow I'm not going to waste my IF intake on a SFS when I can get that from healthy fruit and veggies that's why I use a 100% SF SFS.
Syl restricts his overall IF intake drastically btw, if you read some of the other posts you'll see that that is the case. And on what grounds you worked it out that he hasn't got IBS is beyond me.
