Recent findings, published by British Columbia Cancer Research Centre, have suggested a low carbohydrate diet can not only restrict weight gain but also cancer development and progression in genetically engineered mouse models. The idea was that cancer cells depend on glucose more than normal cells. Therefore, low carbohydrate diets can act additively with known cancer therapeutic agents to reduce tumor growth. (article 1) Consistent results were also published in Cancer Research, a journal of the American Association for Cancer Research, though the study did not link the diets with its therapeutic effects on cancer patients. (article 2) However, in 2010, a study being published in the Annals of Internal Medicince concluded that a low-carb diet based on animal protein can increase the risk for cancer and death, as meat-based diets often are high in saturated fats and cholestrol. (article 3)
Conflicting results have been demonstrated by scientists. In order to evaluate the accuracy of the studies claiming the effect of diet on tumor proliferation, consistent results of replicated studies in humans may be further demonstrated. More importantly, as "therapy" is defined as the attempted remediation of a health problem following a diagnosis, low-carb, high-protein diets may not be used as a way to slow tumor growth as long as more adverse effects would result, for example, anorexia, kidney failure and cardiovascular complications.
Is low-carb, high-protein diets a way to slow tumor growth?
