A Vegan Diet and Cancer

A vegan diet is characterized by abstaining from the use of any animal products, including the consumption of meat, eggs, and dairy products.1 The position of both American Dietetic Association and the Academy of Nutrition and Dietetics is that an appropriately planned vegan diet provides sufficient nutrition and may offer additional health benefits during all stages of life.2,3

It is estimated that approximately 2% of the population in the United States follows a vegan diet. As a result, few prior prospective studies stratified their data by type of vegetarian, including veganism, making it difficult to draw definitive conclusions regarding the effect of a vegan diet on cancer risk. Most studies suggest that a vegan diet lowers the risk of any cancer, but few show significance for individual cancer type.4
