I’m Jason & I run the blog along with Marcus, my girlfriend has similar problems to the ones you describe & it can be really difficult to find out which foods are causing the problems. Unfortunately many ‘healthy’ foods can also cause problems with some people, for example many fruits and veges contain FODMAPs which can cause severe symptoms.

The best way to find which foods are causing your problems is to go on a strict elimination diet and then reintroduce foods one at a time. An excellent book which details how to do an elimination diet is this book. Typically foods that can be causing auto-immune problems (gut issues) are eliminated on the Paleo diet (grains, dairy, legumes), which I presume you are avoiding? Other typical problem foods (which are allowed on the Paleo diet) can be, eggs, nuts, seeds and nightshades (potatoes, aubergine, tomatoes).

BTW home-made cultured / fermented veges taste amazing, much better than shop bought stuff which is pasteurised, thus killing all the helpful bacteria! Probiotics can also be bought in pill form if you really can’t stomach home made sauerkraut too. Stock made from animal bones is also a great food to help heal the gut as well, I’m planning a blog post about this so keep checking – I’m just waiting until I have enough bones to make another batch.

I hope I’ve given you some ideas and please let us know how you get on, hopefully your healthy ways will eventually rub off on your husband ; )

Regards,
Jason
