New research is claiming that people who eat a vegetarian diet are 14 percent less likely to develop cancer.
A team at Oxford University also found that pescatarians, who consume fish, cut their risk by 10 percent , while carnivores who eat only small quantities of meat have a reduced rate of 2 percent.
The study examined the diets of 470 thousand people.
