the mice on restricted diets.

restrict caloric intake.13 Researchers are encouraged by the longevity of a single monkey who has reached 38 years

With rudimentary laboratories, one could argue that more was accomplished with regards to the effect of
diet on cancer in the former half of the century, as revolutionary researchers like Tannenbaum, Rous, and their colleagues provided us with dozens of animal studies linking
diet and cancer by exposing
mice to free radical - laden vegetable oils.32, 33 Several decades later, two other researchers, Dayton and Pearce, provided one of the few studies revealing what happens when we give humans vegetable oils and their accompanying free radicals when they randomized men to a corn oil solution and a similar rise in cancer followed.34 It is no surprise that corn oil is often used in animal studies to cause cancer, as the ingestion of damaging free radicals predictably hastens cancer development.35 Furthermore, these scientists were the first to show that fasting,
restricting calories, and cutting carbohydrates could lower the chance of cancer in animals exposed to dangerous chemicals and carcinogens.
