Defining episodes of diarrhoea: results from a three-country study in Sub-Saharan Africa.

The study was conducted to assess the effect of definition of episode on diarrhoeal morbidity and to develop a means of adjusting estimates of morbidity for the definition of episode used. This paper reports on a cohort study of 374 children, aged 9-32 months, in three African countries, which recorded frequency and consistency of stool over a seven-month period. Different definitions of episode were applied to these data to assess their effect on annualized diarrhoeal morbidity.

The conceptual framework for estimating food energy requirement.

Objective: In anticipation of the revision of the 1985 Food and Agricultural Organization/World Health Organization/United Nations University (FAO/ WHO/UNU) Expert Consultation Report on 'Energy and Protein Requirements', recent scientific knowledge on the principles underlying the estimation of energy requirement is reviewed.

Design: This paper carries out a historical review of the scientific rationale adopted by previous FAO/WHO technical reports on energy requirement, discusses the concepts used in assessing basal metabolic rate (BMR), energy expenditure, physical activity level (PAL), and examines current controversial areas. Recommendations and areas of future research are presented.

Food and health in Europe: a new basis for action.

Poor nutrition, foodborne disease and lack of secure access to good food make an important contribution to the burden of disease and death in the WHO European Region. Better diets, food safety and food security will not only reduce or prevent suffering to individuals and societies but also help cut costs to health care systems and bring social and economic benefits to countries. People's chances for a healthy diet depend less on individual choices than on what food is available and whether it is affordable.

The high-fat Greek diet: a recipe for all?

Objective: To examine critically the published results of dietary surveys on the fat content of the Greek diet, and to assess its evolution and its relationship to the health of the Greeks. To consider the implications of these findings for current views on the nature and health implications of the traditional Mediterranean diet and how best to define it for use in modern policy making.

Design: A systematic review of the literature on food consumption in Greece.
