My family is full of coeliacs - I'm about the only one who can eat gluten. I've had the blood test and I don't have CD. My problem is alopecia universalis - for the last 18 years I haven't had a single hair on my entire body (I wear a wig). What is the most likely cause for that? Gluten!?! But I love bread - it’s my favourite food! It’s the only gluten I eat.

- from the Fed Up Roadshow 2010 (In my experience, relatives of coeliacs may pass the blood test but often do much better when avoiding gluten. It could be that they are not eating enough gluten when they do the test because the family diet is likely to be low in gluten to avoid contamination for the coeliacs – S)
