Colorectal Cancer Prevention

Updated: Jun 30, 2022

Prevention is infinitely preferable in cost and human suffering than treatment after-the-fact. For instance, lung cancer was the most common cause of death in the 1960’s when most people smoked and now it is a rare condition among non-smokers. Similarly, there is compelling evidence that a high fiber, low carbohydrate diet has huge potential for reducing colorectal cancer (CRC). In the same way that lung cancer was reduced by eliminating the root cause (smoking), new cases of CRC might be reduced by 93% (a staggering 1.2 million cases a year) by reversing the fiber to carb ratio in our staple foods. Accomplishing this goal requires a paradigm shift in prevention nutrition and would depend on convincing people of the need to change behavior and the affordability and availability of equally acceptable alternative foods.

The Evidence

Colorectal cancer (CRC) is the third commonest cancer after lung, prostate and breast cancer
