''He's done a great job in changing my diet after we established I am allergic to some food ingredients, like gluten,'' Djokovic said of the diagnosis that turned around his career two years ago. ''It means I can't eat stuff like pizza, pasta and bread. I have lost some weight but it's only helped me because my movement is

''There are a whole lot of people who believe they are gluten intolerant, who don't have coeliac disease,'' says Professor Peter Gibson, professor of gastroenterology at the Alfred Hospital in Melbourne. ''This is very controversial because there is a quite big percentage - even up to 10 per cent - of people who are avoiding gluten because they think gluten is their problem. Naturopaths have put them on a diet, or they have done it
As yet unpublished research from Monash University, co-written by Professor Gibson, found only 14 per cent of people on gluten-free diets were put on the regime by a doctor. Almost half had simply decided to cut wheat and grains from their diet because they assumed they were intolerant. More than 60 per cent had not been tested
''It's a very emotive area,'' Gibson said. ''Fortunately, now there is a lot of work going on around the world trying to

Finland has done more than any other nation to identify its coeliacs. It has the most reliable data on increased prevalence: a doubling, from 1 per cent to 2 per cent between 1979 and 2000. Fins have been eating gluten free
It is accepted that coeliac disease affects about one in every 100 Australians - although there is no local research to confirm the Finnish findings. Some academics argue perceived increases in coeliac disease are heightened by
The increase in people identifying with non-coeliac gluten intolerance is more conflicted. An editorial in the Medical Journal of Australia last year noted the distinction: ''The popularity of the 'fad' gluten-free diet might be peaking, but
Penny Dellsperger, a dietitian at Coeliac NSW, said there were significant medical risks to people adopting gluten free diets without first ascertaining whether they suffered coeliac disease. She said the symptoms could easily relate to
