Changes in potato consumption in different stages of life in Norway.

The aim of this study is to contribute to a better understanding of factors promoting the decline in potato consumption in Norway from the mid-1970s to mid-l990s, as well as with what foods the potatoes have been replaced. The article is based on three surveys, all of them carried out on nation-wide representative samples of the Norwegian population: records of household consumption from 1976 to 1995, N=1000-1500 each year; questionnaire surveys of food frequency from 1986 to 1996, N=3000 every other year; and telephone interviews of yesterday's eating events in 1997, N=1177. The results indicated that it was particularly the young people who lived alone who had dropped eating boiled potatoes. The use frequency increased when there was a partner and it increased even more when there where children in the household. Furthermore, higher socio-economic groups were particularly prone to drop using boiled potatoes, and they had a distinctly different use pattern of alternative staple foods than the others. The data indicated that the potato is more commonly used together with certain foods (fish, carrots and broccoli) than others. Therefore, omitting the potato from the meal may signify other dietary changes than the exchange of staple foods.

Nordic meals: methodological notes on a comparative survey.

This article discusses some methodological aspects of the project "Eating and Modern Everyday Life. A Comparative Survey of Nordic Countries". Data were collected in April 1997 with computer assisted telephone interviews in Denmark, Finland, Norway and Sweden. Questionnaires included a record of the informant's eating on the day before the interview, attitudes related to current food discourses, socio-demographic information and a few open-ended questions. The emphasis was on social and cultural aspects of eating. One aim of this study is to investigate whether regular meals are substituted by irregular eating patterns. In order to avoid any predefined meal concepts the questionnaire therefore focused on eating events. The reconstruction of data is based on a model called the eating system. The model has three dimensions: the eating pattern (the rhythm and the number of eating events, the alternations of hot and cold eating events), the meal format (the composition of the main course, the sequence of the whole meal) and the social organization of eating (where and with whom people are eating, who did the cooking). Some preliminary results are presented suggesting that the questionnaire and the analytical model suit the purpose of studying modernization through the field of food.

[Do Norwegian infants get too little iron in the diet?].

Since 1963 iron-fortified porridge has been recommended for Norwegian infants. Since then important changes have taken place with regard to infant nutrition. Since the late 1960s there has been a dramatic increase in the frequency of breast-feeding. Breast-feeding prevents anemia during the first six months. Most parents use iron-fortified porridge, but to a somewhat lesser extent than recommended. Recent studies indicate that the iron status of Norwegian infants is acceptable. The authors discuss iron intake in the light of present knowledge of iron bioavailability. The authors do not find sufficient evidence for changing recommendations to parents on infant diet, nor for more extensive use of iron-fortified porridge or for using infant milk-formula for a longer time.

Patterns of sugar consumption in early childhood.

Patterns of sugar consumption were studied prospectively in a birth cohort of 231 Norwegian children. Information on dietary habits and sugar consumption was collected at the children's ages of 10 months, 18 months, and 2 yr. The results of the factor analyses showed that the children's sugar consumption constituted a separate dimension of dietary habits. Patterns of sugar consumption seemed to be established already during infancy. The children's sugar consumption increased from infancy to the age of 2 yr, and the patterns of sugar consumption also seemed to be maintained throughout the first years of early childhood. Sugar consumption was also analyzed multivariately using indicators of social background and family size as explanatory variables, but the explanatory power of these variables was rather poor and decreasing with age.

Food intake and patterns of feeding of Norwegian infants.

Norway has formed a policy on infant feeding, expressed as dietary allowances and guidelines concerning food intake. In a longitudinal and prospective study of health and development during infancy, the feeding patterns of 217 Norwegian infants were followed in order to evaluate the policy. The findings indicated that prevailing guidelines were largely followed by the parents. Forty-five per cent still got breastmilk at 6 months. Solid foods were usually introduced around 4-5 months, iron-enriched porridge being commonly used. At 10 months 91 per cent were given bread. The nutrient intakes at 10 months were mainly in accordance with the recommendations. The quality of the diet seemed to diminish somewhat when sandwiches replaced porridge. More emphasis should be put upon toddlers' diet in counselling the parents.

A silent revolution--changes in maternity ward routines with regard to infant feeding in Norway 1973-1982.

Identical surveys of feeding routines were conducted in all Norwegian maternity wards in 1973 and 1982. The first survey was followed up by a set of recommendations on routines conducive to breastfeeding. Significant positive changes had taken place between the two surveys. Breastfeeding was in 1982 initiated within two hours in nearly all wards. Some form of demand feeding and rooming in for a large part of the day, had been adopted by a majority of the maternity wards. The use of supplements to breastfeeding had shifted from extensive use of home made cow's milk mixtures to sugar water and infant formulas "when needed". The use of human milk from milk banks had increased, but was still not universal, even in the large wards. Most maternity wards were still test weighing infants before and after feedings. The above changes have taken place in a period when the rate of breastfeeding has increased significantly in Norway.
