Phytochemicals and cancer an overview

The epidemiological evidence suggests that diet is a significant factor in the development of cancer. In their classic epidemiological study, Doll and Peto (1981) estimated that diet was responsible for as many as 35% of cancers in the West. An encyclopaedic report on nutrition and cancer by the World Cancer Research Fund (1997) has confirmed the central importance of diet as a major determinant of many forms of cancer across the globe. The interactions between diet and the biological processes leading to the 

Finally, susceptibility to cancer may be increased by an inadequate intake of biologically active food components, which, though not classified as nutrients, may nevertheless exert important anti-carcinogenic effects over
