The study, which involved 1500 people, suggests that those who drink beer or grain-based liquors such as whisky may increase their risk of disease.
Researchers will tell the annual scientific meeting of the American College of Gastroenterology in New York, US, that regular drinkers of wine appear to enjoy a massive advantage compared with other people.
The conclusion comes from a study of patients who underwent colonoscopies during an eight-month period ending in April this year.
Researchers from the State University of New York, Stony Brook, US, analysed the proportion of patients who were found to have "significant" polyps. Patients with a previous history of bowel disease were excluded from the study.
The researchers, led by Dr Catherine Messina, found that just one per cent of wine drinkers suffered from polyps compared with 12 per cent of non-drinkers and 18 per cent of those who consumed alcohol derived from grain.
Patients were defined as drinkers if they took just one drink a week.
According to a preliminary report of the study, the results were statistically significant. However the researchers will face questions about the extent to which they took account of confounding factors such as social class and dietary habits.
