Eating more food of plant origin and less of animal origin can bring significant reduction in incidence of cancer. The World Cancer Research Fund study also recommends:
a diet rich in fruit and vegetables. It should prevent 20 per cent of all cancers.
limiting alcohol consumption to one or two drinks a day. It should prevent 20 per cent of all cancers of the mouth/throat, colon and breast.
changing diets overall based on its findings/recommendations. It could effect a 75 per cent reduction in colon cancer, a 50 per cent reduction in breast cancer and a 33 per cent reduction in lung cancer.
