Has anyone tried the Boots food intolerance test?

I'm afraid I get very irritated with all this intolerance nonsense - it's usually just food preferences.

At one time you would know a handful of people who had gluten-intolerance because of coeliac disease or similar, and a few lactose-intolerant, now almost every other person is allergic to something!

When my second daughter was a baby she became very ill, repeatedly. It took the doctors several months and very many tests to discover that (among other problems) she had a disaccharide intolerance. I just don't believe that any 'over the counter' test could give accurate results that it took hospital doctors months to achieve.

Sounds very fishy in terms of the science.
There is a whole industry out there trying to convince people that they have intolerance to a long list of foods.
Just because something is offered by Boots does not mean it works. They were flogging some unproven device that claims to detect breast cancer at one stage. And then there are shelves and shelves of pills and potions.
Cutting out too many foods can leave you with an inadequate diet.
Best way to find out if foods are disagreeing is to cut them out, one at a time, for a couple of weeks and then start again. Make notes of how you feel before hand , during and after.
