An Alberta researcher has determined that Canada and Europe have the most incidences of inflammatory bowel disease.
The University of Calgary gastroenterologist and epidemiologist says 0.5 per cent of Canadians suffer from some form of IBD.
The report looked at more than 200 studies from around the world and found that the disease is becoming more prevalent, particularly in industrialized countries.
The possible dietary explanation is that developed countries ingest more refined sugars, more fat and less fibre.
Other research say the cause is pollution and lifestyle factors, including the effect of smoking.
The findings are published in the journal “Gastroenterology.”
