Affluent develop taste for gluten-free? (Sydney Morning Herald July 20)

Here is the Food Intolerance Network's response to Sarah Whyte's article

Dear Sarah

It is very simplistic to report that all those who are not diagnosed coeliacs must have chosen to be gluten-free for fad reasons. There is a scientifically recognised condition called gluten intolerance which is far more common and the number of undiagnosed coeliacs is considered to far out-number those diagnosed. You might also want to consider that a switch to gluten-free food usually means dramatically lowering one's intake of processed food, thus removing many additives known to affect people adversely and leading to markedly better health.

Gluten intolerance has many of the same symptoms as those suffered by coeliacs but has no known genetic basis. It is sometimes called "non-coeliac gluten intolerance".

Some of those who think they are reacting to gluten, however, may be reacting to fructans - research results are still coming in this area eg

You quote a figure of 1% for coeliacs, but experts say many Australians experiencing chronic digestive problems caused by gluten intolerance may be suffering from coeliac disease. New figures suggest 4 out of 5 patients with coeliac disease are unaware they have the illness. Australian doctors are being urged to be more vigilant. The increase in coeliac tests in Australia is a response to this call, not a fad.

Diagnosed food intolerance has been reported to affect 19% of the Australian population.
