Dietary survey "HEUREKA" 1991: dietary intake of a Swiss collective assessed by a self-administered 24-hour recall questionnaire.

Food consumption (divided into 10 food groups) as well as energy and main nutrient intake of a Swiss collective (n = 3653) aged 7 years and older was studied. The caloric density was much improved for all five age groups considered as compared with findings in former studies. Carbohydrates gained and alcohol lost significance as main energy suppliers. These results indicate a positive trend in the dietary habits of the collective and suggest an improvement in the dietary habits of the Swiss population as a whole.
