For many years I had digestive problems, went for many tests and had camera's inserted in various orifices but everything came back negative and still the problems remained. The mystery about this is that I had one of the healthiest diets you could have, lots of fruit and veg and good protein but still nothing was working as it should.
Then a while back, I came across an article in Pyschologies magazine, it was about a condition called fructose malabsorption which means that fructose cannot be absorbed correctly and remains in the gastro-intestinal tract causing all sorts of problems similar to lactose intolerance, IBS and coeliac disease. So, I cut back on the fruit and lo and behold, everything started working normally. There are a lot of people I know with IBS and these other digestive problems, so I thought I would share this as I had been treated and tested for all these things and no-one ever mentioned fructose malabsorption, and it's really easy to test for. So, if you've been experiencing any digestive problems and still every test comes back negative then this might be your problem.
Apparently, if you have this, red wine is one of the worst things you could drink. Red wine doesn't go down well with me and affects me quite badly but gin, which is one of the best things to drink if you have this, goes down very well, and I've never had a bad night on gin on those rare occasions when I indulge.
Wheat also contains fructans which can cause bloating and wind and which is why people who have this condition, think they have coeliac disease because of the difference it makes to their system when they cut out wheat.
