Rosanna Davison says her message was miscommunicated, when she was reported to have linked gluten to arthritis, schizophrenia and autism in an interview.
The remarks provoked a huge storm of controversy and the former Miss World was criticised by many people including health professionals.
Yesterday, the Health Minister Leo Varadkar appeared to weigh in on the controversy, after he retweeted one user who said: "Why won't my mam and dad get back together #blamegluten".
In a statement on Monday, 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 model and author of 'Eat Yourself Beautiful' says there is no proper evidence to prove or disprove the claims.
And she said told the Anton Savage Show on Today FM she has been very hurt by some of the commentary about her interview.
