The logical extension of discrete mass systems is one of an infinite number of masses. In the limit, this is a continuous system. Take the generalized beam-column as a generic representation:

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:
