Objective: A consideration of eating patterns in the general population is necessary when deriving food-based dietary guidelines (FBDG) as promoting the intake of one food may indirectly result in the increased consumption of another, which may not always be desirable. A number of issues that influence meal patterns such as temporal distribution of food intake (using data from the Netherlands), converging and diverging foods (using data from Ireland) and meals eaten inside and outside of the home (using data from the UK) are examined and discussed in the context of developing FBDG. Setting: Food intake databases from three EU countries: The Netherlands, Ireland and the UK. Results: The hot meal (dinner) was found to be the main contributor to the intake of energy and macro-nutrients in the Dutch population. It was also the main contributor to the intake of all micro-nutrients with the exception of calcium where the bread meal contributed a similar proportion as the hot meal to the intake of this micronutrient. Furthermore, fruit intake showed a very different temporal distribution to vegetable intake. Exploring the convergence of certain foods in the Irish population also revealed differences between fruit and vegetables. A low correlation was shown for consumers of fruit and vegetables indicating that being a high fruit consumer did not suggest being also a high vegetable consumer. An examination of where meals were consumed among British adults showed that 71% of all meals were consumed inside the home while 29% were consumed outside. 27% of food energy and 45% of alcohol energy was consumed out of home by the total population. In addition, those eating less of their foods out of home obtained a lower proportion of their food energy from fat and protein and a higher proportion from carbohydrate. A different demographic profile was associated with eating out compared to eating in, comprising more males and younger individuals. Conclusions: Information on patterns of food intake and food habits, specifically temporal distribution, the convergence and divergence of foods and foods consumed inside and outside of the home, give a culturally specific picture of food consumption practices within a population. This should enable the development of more culturally acceptable and realistic FBDG.

Over the last three decades, dietary pattern analysis has come to the forefront of nutritional epidemiology, where the combined effects of total diet on health can be examined. Two analytical approaches are commonly used: a priori and a posteriori. Cluster analysis is a commonly used a posteriori approach, where dietary patterns are derived based on differences in mean dietary intake separating individuals into mutually exclusive, non-overlapping groups. This review examines the literature on dietary patterns derived by cluster analysis in adult population groups, focusing, in particular, on methodological considerations, reproducibility, validity and the effect of energy mis-reporting. There is a wealth of research suggesting that the human diet can be described in terms of a limited number of eating patterns in healthy population groups using cluster analysis, where studies have accounted for differences in sex, age, socio-economic status, geographical area and weight status. Furthermore, patterns have been used to explore relationships with health and chronic diseases and more recently with nutritional biomarkers, suggesting that these patterns are biologically meaningful. Overall, it is apparent that consistent trends emerge when using cluster analysis to derive dietary patterns; however, future studies should focus on the inconsistencies in methodology and the effect of energy mis-reporting.

Objective: The purpose of this survey was to establish a database of habitual food and drink consumption in a representative sample of Irish adults aged 18-64 years.

Objective: To identify the most important motivations for food choice from the point of view of the consumer in the Irish population, and to characterize those subjects who do and do not regard nutrition as a signi®cant consideration in food choice. Design: As part of a pan-European Union (EU) survey on consumer attitudes to food, nutrition and health, a quota-controlled, nationally representative sample of Irish adults (n = 1009) aged 15 years upwards, completed an interview-assisted, closeended questionnaire. Subjects selected three factors, from a list of 15, which they believed had the greatest in¯uence on their food choice. Setting: The interviews for the survey were conducted in subjects' homes. Results:`Quality/freshness of food' was the most frequently selected food choice factor (51%) followed by`taste' (43%) and`trying to eat a healthy diet' (36%). Female gender, increasing age and higher levels of education were found to be independent sociodemographic factors affecting the selection of`trying to eat a healthy diet' as an important factor in food choice. Conclusions: Although included in the top ®ve most frequently selected factors affecting food choice, nutrition/healthy eating does not appear to have top priority for the majority of Irish adults. There are differences between the various sociodemographic groups within the population; males and younger subjects appear to require speci®c nutrition promotion messages.
