Coeliac disease affects only ~1% of the population… but the numbers are much higher for non-coeliac gluten sensitivity, which has been reported to affect up to 13% of us!

The problem is: do we unquestionably know what “non-coeliac gluten sensitivity” really is?

Can it be medically diagnosed?

Some say it’s a sub-type of coeliac disease – is that true?

If not, how can you find out if you truly have it?

In this report, we examine the latest scientific literature on non-coeliac gluten sensitivity – straight from the source! You’ll also get a practical diagnostic algorithm, and we’ll show you how to interpret it.
