5.1 Introduction In this chapter, copper is considered as a case study for the measurement of the effect of nutrient intake. The importance of the role of copper in biological systems is first explored in a brief review of selected human cuproenzymes

4.1 Introduction Minerals are the inorganic elements, other than carbon, hydrogen, oxygen and nitrogen, which remain behind in the ash when food is incinerated. They are usually divided into two groups – macrominerals and microminerals (or trace elements). The terms are historical in origin and originated at a time when the development of analytical equipment was still in its infancy and ‘trace’ was used to refer to components whose presence could be detected, but not quantified. Modern analytical equipment that allows determination of elements

A. Trichopoulou and A. Naska, University of Athens 2.1 Introduction Documenting and monitoring dietary patterns are priorities in nutritional epi￾demiology, in the planning of national food and nutrition policies and in the evaluation of nutrition education strategies. Early efforts in documenting dietary patterns were focused on identifying the specific nutrients that may be respon￾sible for effects on people’s health, but recently research has expanded towards studying patterns of food intake. Food data are often derived from:
