The Health Minister Leo Varadkar appears to have weighed in on the Rosanna Davison gluten controversy.

The model, author and nutritional therapist sparked controversy when she linked gluten to arthritis, schizophrenia and autism in a newspaper article.

The tongue-in-cheek BlameGluten hashtag has been in action all day on Twitter.

And now Mr Varadkar has retweeted one user who said "Why won't my mam and dad get back together #blamegluten".

However, some users have already criticised the minister for making light of a serious issue.

In a statement yesterday, 31-year-old Davison said: " My qualification in Nutritional Therapy from the College of Naturopathic Medicine enables me to advise on a client's diet and nutritional needs, but always in conjunction with their GP if they're on medication, have a disease or need to get tests done".

She added said she was "by no means stating that gluten causes arthritis or any other disease, or that they can be cured by removing it from the diet".

The office of the minister says it has no comment on the issue.
