ABSTRACT
Patterns of disease and mortality differ around the world and one of the factors that can be correlated with many of the differences is diet, although there are obviously other environmental (and genetic) factors involved. This chapter is concerned with the ways in which we can gather evidence that diet is, or may be, a factor in the development of chronic noncommunicable diseases (especially atherosclerosis and coronary heart disease, and cancer), and how we can use these ndings to produce guidelines for a prudent or healthful diet.
