WEDNESDAY, Dec. 6 (HealthDay News) -- Women who eat a Western-type diet that includes foods such as pizza, alcohol and meat have a risk of adenomas and colorectal cancer that is 40 percent to 60 percent higher than their peers who tend to eat fruits and vegetables, according to the results of a French study published in the Dec. 1 issue of the American Journal of Epidemiology.
Marie-Christine Boutron-Ruault, M.D., Ph.D., and colleagues from the Institut Gustave Roussy in Villejuif, France, examined dietary patterns and the risk of colorectal tumors in 516 women with adenomas and 4,804 polyp-free women, and in 172 women with colorectal cancer and 67,312 cancer-free women. Diets were classified as healthy (fruits and vegetables), Western (pizza, cake, butter), drinker (snacks, alcoholic beverages), or meat eaters (meat, margarine).
Comparing the top and bottom 25 percent of women in each category, the researchers found that the Western and drinker patterns were associated with significantly higher risk of adenomas (relative risks 1.39, 1.42, respectively). Colorectal cancer was significantly higher for meat eaters (relative risk, 1.58).
"Dietary patterns that reflect a Western way of life are associated with a higher risk of colorectal tumors," Boutron-Ruault and colleagues conclude.
