Is America a nation of gullible nitwits? For the record, there is no country on earth that can cast the first stone. Still, judging by the blind faith in loopy science that has turned the gluten-free diet into a $23bn movement, it is a valid question.
Gluten is a “gluey” protein found in wheat, barley and rye. It makes cakes go fluffy and bread taste moist. Wheat was one of the first domesticated food crops and is a staple food around the world. Nevertheless, a third of Americans now avoid gluten in the belief that it causes a range of ills from diabetes, obesity, autism and Alzheimer’s to joint pain, flatulence and diarrhoea.
A minuscule market that once served the 1% of Americans who have coeliac disease (and must avoid gluten) now commands the top shelves in the food aisles. Of all the egregious examples of corporate welfare, our paying huge premiums to Kraft and Kellogg’s for non-existent health benefits must take the gluten-free biscuit.
