A review study in the October 2011 issue of Nutrition & Metabolism looked at the possible beneficial effects of a low carbohydrate diet on cancer prevention and treatment. Recent evidence has caused some to suggest that reducing carbohydrate intake may be able to suppress, or delay, the start of cancer and/or the growth of existing tumors might be slowed down (... or in my case, "preventing a recurrence"). The reasons for this hypothesis? Most malignant cells depend on glucose for energy, high insulin and IGF-1 levels can promote tumor cell proliferation and ketone bodies may not be usable by tumor cells for metabolic demands. In the course of their review, the study’s authors did conclude that evidence does exist showing chronically elevated blood glucose, insulin and IFG-1 levels can make it easier for new tumors to grow and that restricting carbohydrates may be beneficial in reducing your risk of developing cancer in the first place. But wait. It gets even better.
Another potential benefit of a low carbohydrate diet is the positive effect it can have on inflammation, which “is a well-established driver of early tumorigenesis and accompanies most, if not all cancers.” Fortunately for us, by eliminating grains, the paleo diet does a great job of reducing inflammation. Why? According to the researchers, “grains can induce inflammation in susceptible individuals due to their content of omega-6 fatty acids, lectins and gluten.” And while the paleo diet is not necessarily a low carb diet, those eating paleo tend to replace high-GI foods with other, lower GI foods like vegetables, thus reducing the glycemic load, which can also have a positive effect on cancer.
