Does diet affect your UC? 
Definitely not: 5%
Haven't really noticed: 18%
Maybe a bit: 32%
Definitely: 43%
Burp: 2%
The poll results would suggest 43% of us are sweetcorn dodging, fibre-shirking, tomato-phobic, veggie boilers.  
32% of us might pass on a peanut, be a little wary of grapes, but at the end of the day think sod it, and take our chances with a Snickers.
18% of us have our local tandoori on speed dial and in Asda we fill our shopping trolleys with whatever we damn well like.
And 5% of us must have really good dinner parties, where anything goes.  (Food-wise, I mean, not one of those dinner parties where you chuck your car keys into a bowl.)
So it seems food is a bit of a grey area.  Personally, I eat and drink pretty much what I want.  Although I have found red wine makes my tummy grumpy, and nuts are a no-no.  But there’s more to life than Shiraz and pistachios.  I did think about seeing a dietician a while back, but now I’m glad I didn’t.  It might have put me off my grub.
