This study sought to investigate whether women’s Perceptions about butter and

soft margarine vary by the use of these fats. From interviews in 1984 with 102 addle-aged women from a follow-up dietary survey in Helsinki 27% of their households were classified as exclusive butter users, 46% used both butter and margarine and 27% used only margarine. The women evaluated margarine less “tasty” but “lighter”, and “healthier” than butter. Women whose households used butter exclusively rated it more “useful” than those who used margarine, whereas women whose households used exclusively margarine rated it higher on taste than did exclusive butter users. Butter is a valued traditional food in Finland, and probably the taste of butter is still a reference standard for all spreads. Nevertheless some of the respondents had evidently come to like the soft vegetable margarine that was not available in their childho~.

INTRODUCTION

Traditionally, the Finnish diet has been rich in saturated fat, due particularly to the consumption of butter and high fat milk. For a number of years health education has been aimed at changing fat consumption among the Finnish people (Keys, 1968; Pietinen et uZ., 1988; State Advisory Board on Nut~tion, 1989). Because bread covered with a spread is consumed several times daily, the choice between butter and soft vegetable margarine is a major public health issue in Finland.

This research was financed by the Academy of Finland, the Read Heart Operation Fund, the Social Insurance Institution of Finland, the Juho Vainio Foundation and the Ytj6 Jahnsson Foundation.

Previous studies in Finland concerning the relationships of consumption of fatcontaining foods to perceptions about them have yielded conflicting results. According to Tuorila (1987) in sensory tests liking was the predominant predictor of cons~ption of different types of milk. The subjects indicated a reluctance to change their milk choice although they knew that lowering fat consumption was recommended. On the other hand, Hellemann et al. (1990) found no clear relationship between liking and the choice of dairy vs. vegetable fats as spreads on bread. Other factors, among them health consciousness, were better predictors of choice than taste preference. Studies from other countries are also contradictory: the results differ depending on the specific foods, the methods of measurements, and the groups being studied. Some studies indicate liking to be the predominant predictor of consumption (Shepherd & Stockley, 1985, Tuorila & Pangborn, 1988a), whereas in other studies (Shepherd, 1988) health and nutrition concerns are more closely related to consumption. There are also studies (Tuorila & Pangbom, 1988b; Wardle & Beales, 1986; Pr%tt%i & Keinonen, 1984) that reveal conflicting belief structures related to the consumption of certain high-fat foods. For example, subjects express their liking for chocolate, and yet they recognize that it is “bad for you”. The previous studies have often interpreted perceptions as determinants of food consumption across user groups but consumption can also be a modifier of perceptions. So this study sought to determine whether Finnish women’s perceptions about butter and margarine varied among the users of the two types of spread or among socio-demographic groups.

METHODS

Interviews were conducted with 102 women in Helsinki in 1984. These women were participants in the Multicentre Study on Precursors of Atherosclerosis in Finnish Children (Akerblom et al., 1985). The original sample consisted of 200 families representative of Helsinki residents. Of these families, 154 participated in the first dietary survey in 1980 and 128 in the follow-up in 1983. One hundred and twenty families of those who had participated in 1983 were contacted in 1984. The interview begun with demographic information (Table 1). Socioeconomic status was measured with two variables--occupation and education. The occupations of the household heads were categorized according to criteria used by the Finnish Statistical Center (1980). Households were classified as butter users (margarine not used at all), marga~ne users (butter not used at all), or mixed (both butter and margarine used). Margarines used as spreads on bread in Finland are softer than butter and made of vegetable oils. In the 1983 study the women had reported on their personal use of butter and margarine but there were no differences between the 1983 and 1984 data. The women were asked to rate the two fats on a row of seven dashes labelled at the extremes in Finnish “‘tasty-not tasty”, “heavy-light”, ‘~nut~tious-not nut~tious”, “strong-weak”, “ healthy-unhealthy”, “ high fat-low fat” and “useful-not useful” (the Finnish word “tarpeellinen” translates roughly as “useful” in the sense of something that is “necessary” or “required” as contrasted with “optional” or “not required”). These terms were applied to food during ethnographic interviews carried out among a comparable group of women before the final study.

USE AND PERCEPTIONS OF BUTTER AND MARGARINE

The order in which the scales were presented to the respondents was randomized. Student’s t-test for paired observations was used to test for differences in butter and margarine ratings among all respondents, Hotelling’s t-test for differences in ratings between the groups. A difference was considered statistically sig~fi~nt if pcO-05. Beliefs and attitudes were further explored by open-ended questions from which the commentaries on fats described below originate.

RESULTS Perceptions of Butter and Margarine

Of the 102 households in the sample, 27% reported to be exclusive butter users, 46% used both butter and margarine, and 27% used only margarine. Since these pro~~ons did not vary subst~ti~ly with socioeconomic status (Table 1), it is not controlled in the analyses of associations between perceptions and use. The women evaluated butter as very “tasty”, “heavy”, and “fat” whereas margarine received more neutral evaluations (Figure 1) Older women found butter tastier, stronger and more nutritious than did the younger women. Subjects who had lived in a rural area in their childhood rated butter as stronger than did women with an urban origin. Women with a higher educational level found butter to be more unhealthy than women with lower educational levels. In contrast to butter, there were no relationships between socio-demographic characteristics and opinions about margarine, with the exception that women with higher educational levels considered margarine healthier.

Perceptions with Different Users

Women from households using butter only gave higher ratings to butter for usefulness than did those whose household used margarine only (Figure 2). On the other hand, the tastiness of butter was unrelated to its use, a finding that would be expected given the relative absence of variation in the higher “tasty” ratings of butter. Exclusive margarine users rated that product more highly than non-users for tastiness (Figure 3). The evaluations of usefulness of margarine did not differ significantly with its use.

Vkws of Butter and ~urg~ri~e The open-ended interviews revealed more reasons for choosing either butter or margarine. Reasons for use of butter included taste, tradition and economy, sometimes in conflict with health perceptions: “Butter tastes better. Fat should be avoided, but we use it because of taste. Both of our parents died of heart attacks, so one should do all one can to avoid health risks.” “Both parents are from Karelia, and there they use a lot of fat. No matter how much one knows about the harmfulness of fat, one doesn’t change habits; it’s in the blood. I’m still young and can still change my habits a bit later”. “They talk a lot about the healthfulness of vegetable foods, [and] that one should reduce fat intake. But earlier they used a lot of Epork fat] and they did all right. In earlier times there was a shortage of butter; not anymore. People have to have pleasures. Butter is good”. Some butter users ascribed positive health effects to butter such as its presumed value as a source of vitamin A. Butter was regarded as safer because it is a “natural” product. Reasons for using margarine were taste, health, price, and spreadability. The major theme was health, and margarine users often expressed negative, almost moralizing opinions about butter and butter users: “You can watch those fat people and see how much butter they put on their bread.” “At the workplace cafeteria one gets an awful, dreadful feeling. Apparently it’s from the animal fat they use.” Some respondents expressed great ambivalence concerning their choices of fats: “To me the whole discussion seems pretty mixed. Opinions contradict one another. Something that’s good at one moment is unhealthy the next. So f have decided to ignore the whole thing and eat what tastes good”.

R. PRiTT;iLii ET AL. DISCUSSION

The direction of the association between socio-demographic characteristics, perceptions and use is similar to studies in other parts of the indust~a~z~ world (see e.g. Sims, 1976; Schafer, 1978, Knapp et af., 1988). However the associations were weak. They may be stronger among average Helsinki residents, because these respondents were willing to continue to participate in a health and nutrition study. In line with previous studies (Tuorila & Pangborn, 1988b; Wardle & Beales, 1989; Pratttill & Reinonen, 1984), the results reveal ambivalent and contradictory attitudes, especially towards butter. This coni-lict between liking or preference and health concerns appears to be typical of Western Protestant cultures (Mead, 1943). The ratings and the answers to the open-ended questions were consistent with margarine users liking the taste of butter but placing a higher value on health as a criterion for food selection. For butter users, taste appeared to be more important but they also found some positive health effects for their butter eating. In this study the correlations between husbands’, children’s and housewives fat ratings could not be analysed. To understand the development of household fat choices, interactions between household members in relation to fat preferences and ratings should be analysed. In addition, it would be important to analyse fat preferences among persons who have not shifted from one spread type to another. All respondents believed butter to be tasty. Butter is a valued traditional food in

Finland and so the taste of butter may be a reference standard for a11 spreads. Households in Helsinki did not always eat butter although the respondents liked it. Some households evidently had “learned” to like margarine, maybe since soft margarine became available in 1969 (Heino, 1989). It has sometimes been asked whether “people eat what they like” or “like what they eat” (see e.g. Lewin, 1943). It seems that exclusive butter users eat what they like whereas margarine users like what they eat.
