I think by and large anything that has more SF than IF should work, but overall IF matters too. plus, this is where the FODMAP thing comes in that there are additional caution rules.
Btw if someone like Syl has FODMAP trouble, the most obvious way to test whether they have problems on top of that, ie have IBS (which is most often characterised by responding negatively to digestive stimulants such as alcohol, caffeine, IF and fat) - do you think that if Syl ate spinach and ate strawberries and raspberries, beansprouts or even oranges (as a fruit) that he'd be fine? These are all FODMAP safe yet you may still have trouble with them ie have IBS as well, these two conditions very often overlap..
