Role of Fiber in preventing Colon Cancer

Whole grains are a major source of dietary fiber and contain germ, endosperm, and bran, in contrast with refined grains that contain only the endosperm. The germ and bran contain numerous nutrients, which are removed during the refining process. In addition, whole grains are a major source of several vitamins, minerals, and phytochemicals, which have anticancer properties and could plausibly influence the risk of colorectal cancer by several potential mechanisms.

It has been found that the risk reduction in risk of colorectal cancer was seen with only 10 g daily of total dietary fiber the legumes had the maximum reduction while fruit and vegetable fiber had somewhat lesser effect and cereal fiber somewhere in-between. Common legumes include lentils or dal  chickpeas or chana and  beans or rajma/lobia.

Along with preventing colon cancer these food items have other benefits to your health as well such as increased stool bulk and dilution of carcinogens in the colonic lumen, reduced transit time, and bacterial fermentation of fibre to short chain fatty acids. The very important European Prospective Investigation into Cancer and Nutrition (EPIC) study reported a linear decrease in the risk of colorectal cancer with increasing fiber intake and a subsequent analysis reported an 18% increased risk of colorectal cancer with low fiber intake.

In conclusion it is highly recommended to increase intake of dietary fibre to reduce risk of colorectal cancer in addition to significant reduction of processed red meat and alcohol.
