The focus of this article is to emphasize and summarize the findings of new research regarding colorectal cancer. Specifically, the article says eating a high-fiber diet is now linked with a reduced risk of colorectal cancer. The studies found that the link was the strongest for fiber that's from sources like whole grains and cereals. These findings are based on research from 25 different studies. They found that there's an approximate 10% risk reduction for colorectal cancer for every 10 grams of fiber eaten per day. Therefore, if you eat more than 10 grams of fiber per day, you can reduce your risk even more.
The scientists proved an association, not a cause-and-effect relationship. They say that they're still not entirely sure how this operates on a scientific level. One scientist theorized that fiber may reduce risk by reducing the transit time of food products in the digestive tract. It could also dilute carcinogens found in the colon.
The results from these studies should be understood in context. The WebMD team asked Lona Sandon, an assistant professor at the University of Texas Southwestern, to review the findings. She points out that colon cancer doesn't happen overnight and that adding fiber to your diet in your 50s may not prevent colon cancer in your 60s. Still, these findings point to the fact that adding more fiber to your diet is a smart idea. Doing so can also lead to better cholesterol levels, better blood sugar levels, and less constipation.
