Small Intestine Cancer Risk Lowered By Eating More Fiber and Whole Grains

When it came to total intake of dietary fiber, those who ranked in the top 20% in terms of the amount consumed had 79% of the risk of getting small intestine cancer, when compared with those who ranked in the bottom 20% in consumption. With regard to fiber from grains, the top quintile’s risk was only 51% of the risk of the bottom quintile, while the corresponding relative risk for whole grain foods was 59%.

These findings led the study team to conclude that the “intake of fiber from grains and whole grain foods was inversely associated with small intestinal cancer incidence”. Significantly, the reduction in risk, or in other words the protective effects, offered by these foods were consistent as that for colorectal cancer in this same cohort.


The health benefits of consuming sufficient fiber are countless. Fiber helps regulate cholesterol levels. By making one feel full faster, it also helps in maintaining healthy weight. And, of course, it keeps the bowels moving. That obviously helps keep the bowels clean and lowers the risk of colorectal cancer.

Now, we also have empirical evidence that the protective effects of fiber against cancer extends further, quite literally, up the digestive tract, to the small intestines too. And common sense would tell us that, by acting as an intestinal broom and vacuuming the tract, thus keeping the body cleaner, risks of many other cancers and diseases would be markedly reduced as well.

What is also very interesting is that the reduction in small intestine cancer risk was a lot more significant when it came to fiber from grains (relative risk of 51%) and whole grain foods (59%), as compared with total dietary fiber intake (79%).

What does this tell us? Simple – besides consuming more fiber overall, eat more whole grains and whole grain foods too, and our risk of small intestine cancer will be even more hugely reduced. In addition, our overall health will surely be greatly improved too, since fiber and whole grains are also known to have a host of other health benefits.
