I have suffered from gut issues for almost 30 years, it has become so much worse the older I get.
I have tried everything over those years to try to help myself, literally everything. I follow a low fodmap diet and avoid all of my triggers (caffeine, dairy, certain veg and fruit, high fibre, artificial sweeteners).
I find bread really hard to give up and so eat sourdough bread which is allowed on the low fodmap diet (although I often fall of the low fodmap wagon and eat crackers and regular bread at times too).
So many people say their gut issues improve after they have gone gluten free.
I don't suffer from coeliac disease and I know it is more than likely the fructans in the wheat upsetting me rather than the gluten but I do often wonder if non coeliac gluten sensitivity may be a thing?
I would like to go completely wheat/gluten free for a while just to see if there is any improvement in my issues but my problem is that I find most of the gluten free products either taste disgusting or they have so many nasties in them to make the even slightly resemble gluten products that they really upset my tummy. The other problem I have is that I am actually addicted to bread, I can not go a day without my sourdough toast. Somehow I need to find some tasty alternatives to help during this trial. However, I can't tolerate much corn or rice and high fibre foods wreck my gut. I also have issues with dairy so avoid that too!
So, what do you eat in a day if you are gluten free.
