I can see what this report in Britain's Daily Telegraph was getting at .... but it, oh, so misses so many points.
The writer quotes experts as saying too many people are diagnosing themselves with food allergy and that food allergies are much rarer than people think. They then state that people are starving themselves of nutrients in pointless attempts to avoid food allergies.
Yes, up to a point Lord Copper.
I'm one who self-diagnosed with wheat allergy. I lost half a stone in a year. But I didn't give up wheat or gluten before seeing my GP. As I've said before, I was lucky - I developed obvious symptoms. My mouth and tongue swelled and my skin sprouted peculiar rashes. So I got a referral to a specialist. Before that I'd suffered from all those general symptoms associated with food intolerance. After a big meal of pizzas I spent about a week in the bathroom.
And when the wheat allergy tests came up negative, the specialist made another suggestion by letter. That was salicylate. Subsequently I was able to follow this through with a specialist hospital dietician. I understand not everybody gets this service, not everybody gets obvious symptoms.
The point it is wasn't wheat. It wasn't the pizza crust, it was everything else - the tomato, the spices, the herbs. I'd never liked tinned tomatoes.
Now there is no test for salicylate hypersensitivity. I understand there are other basic chemicals, such as sulphates, that can cause similar problems.
So yes, I accept that wheat allergy is rare. I starved myself of wheat and gluten unnecessarily for a year - but it was an experience and I lost weight. If somebody has allergy or food intolerance symptoms, it doesn't mean there's not a problem - just that there may not be an easy answer.
