So Anne has been preparing our transition to the Specific Carbohydrate Diet (vhttp://www.breakingtheviciouscycle.info), which is clearly something that I am looking forward to.
Basically, complex carbohydrates which are disaccharides (double molecules) and polysaccharides (chain molecules) are not allowed.

Complex carbohydrates that are not easily digested feed harmful bacteria in our intestines causing them to overgrow producing by products and inflaming the intestine wall. The diet works by starving out these bacteria and restoring the balance of bacteria in our gut.

The Specific Carbohydrate Diet™ is biologically correct because it is species appropriate. The allowed foods are mainly those that early man ate before agriculture began. The diet we evolved to eat over millions of years was predominantly one of meat, fish, eggs, vegetables, nuts, low-sugar fruits. Our modern diet including starches, grains, pasta, legumes, and breads has only been consumed for a mere 10,000 years. In the last hundred years the increase in complex sugars and chemical additives in the diet has led to a huge increase in health problems ranging from severe bowel disorders to obesity and brain function disorders. We have not adapted to eat this modern diet as there has not been enough time for natural selection to operate. It therefore makes sense to eat the diet we evolved with.

Now, this would be a rough sell in Ireland, given that potatoes and beer are both banned.  Whiskey only occasionally and only very dry wine.  Bugger this.  No rice or wheat.  But then again we have been on a gluten and dairy free diet for a while.  The good news?  Cheddar cheese can be used freely!  Hurray!

The website has a very long list of 'legal' and 'illegal' foods.  Pretty scary.  But there does seem to be a logic at the bottom of it, and enough anecdotal evidence to suggest that it can work.  We shall see.  Wish me luck.
