Diet and gene interactions

As we have seen, carcinogenesis is a prolonged multi-stage process which usually occurs over many years. Because of its complexity there are, in principle, many critical steps at which food-related substances or metabolic processes may interact with the sequence of events so as to accelerate, delay or even reverse it. Diet-related anti-carcinogenesis can usefully be classified into  

A schematic illustration of these concepts and a summary of the mechanisms through which they may act is given in Fig. 3.1.
