The study found people who eat three-and-a-half ounces of red meat every day have a 17 percent increased risk of colon cancer, compared to someone who eats no red meat at all.
Researchers do not know how the meat increases the risk, but they did note that eating less than 18 ounces of red meat a week showed very little increase in colon cancer risk.
The study was conducted by the American Institute for Cancer Research and the World Cancer Research Fund.
