There is some recent studies that have correlated periodic fasting with preventing cancer. Now there are new findings that fasting along with chemotherapy can help cure some types of cancer. Here's a recent podcast and transcript that explains the latest findings. It appears that the American Cancer Society doesn't think much of fasting though: http://www.cancer.org/Treatment/TreatmentsandSideEffects/ComplementaryandAlternativeMedicine/DietandNutrition/fasting
Over the past 30 years, nobody has seemed to figure out why cancer of all types seems to be increasing in the developed world. They've attributed it to chemicals in the environment, radiation, lack of exercise, eating the wrong foods, inadequate vitamins, and not enough prayer? Maybe it is because we always have 3 square meals? While the poorer sections of the world, sometimes have to go for days between receiving adequate nutrition?
Anthropologists now suggest that fasting may have been "natures way" of cleaning out the body of cancers. Many different religions around the world have featured periodic fasting --did they know something?
