Independent decision making of adolescents regarding food choice

The adolescence period is the stage in the life cycle in which individuals begin to develop independent decision making related to their social environment including their dietary intake. The period is fundamental in the development of longer term eating habits that may be reflected in adulthood. This study aimed to investigate the decision‐making process of adolescents and their dietary behaviour in the achievement of a balanced diet and to determine the underlying factors that may affect these choices. To meet this aim, a three phase data collection was utilized. In phase 1, a baseline questionnaire (n = 239) measured factors affecting dietary behaviour and the barriers in the achievement of a balanced diet. Phase two employed and measured respondents’ (n = 235) independent decision making by rating nineteen menu choices which reflected all options of dietary guidelines. This was analyzed through conjoint analysis. In phase three a subsample (n = 55) from the first two phases completed a food map which determined underlying reasons for food decisions and choice behaviour. Results revealed that when adolescents are given free choice they tend to follow an unbalanced diet with some diets raising concerns for their current and future health. Fifty‐seven percent of respondents displayed serious concerns in their dietary choice of which 18% were identified as requiring immediate intervention. The most noticeable factors affecting dietary choice were the desire to eat foods high in fat and carbohydrates and low in fruit and vegetable consumption. Food‐mapping indicated prior knowledge and attitudes had no effect on the choices made but that that behaviour of parents in the preparation of meals at home and peers in the selection of snack choices had the most influence on the unbalanced diet.     

Food choices and the younger generation

Food choice is influenced by many factors including physical, social and psychological ones. In this research, the food choices of young people in the 9–15 age group were investigated and the possible factors influencing them examined. Observations and questionnaires carried out in schools within Northern Ireland indicated that many young people are inclined to choose high-fat and high-sugar products and often dislike fresh fruit and vegetables. This raises concern, especially with the continued high incidence of coronary heart disease within the province. Further work has suggested that young people are aware of current nutrition policies and the importance of healthy eating, but still fail to put this knowledge into practice.     

Consumer preference among fluid milks: low‐fat vs. high‐fat milk consumption in the United States

The present study uses data from the Continuing Survey of Food Intakes by Individuals 1994–1996, 1998 in order to analyse milk consumption by type, specifically high‐fat milk vs. low‐fat milk. Whereas trend analysis displays an overall increase in low‐fat milk consumption over the last few decades in the United States, a number of individuals still consume high‐fat milk varieties, and overall dietary intakes have yet to achieve recommended levels. In light of recent research regarding fat intakes, it is important to understand what factors might cause consumers to purchase high‐fat options given the number of low‐fat options available in the market. Through the use of Logistic regression, key socio‐economic and demographic variables are analysed in order to determine their impacts on the probability of consuming low‐fat milk vs. high‐fat milk. The results indicate that a number of factors do influence probability of low‐fat milk consumption as compared with high‐fat milk consumption. Most notably, probability of low‐fat milk consumption appears to be positively related to age, education level, and income level. African Americans and other minorities had a lower probability of consuming low‐fat milk when compared with White people in the sample population. Also, those respondents designated as low income or living in the South were less likely to consume low‐fat milk.     

Warning labels on junk food: experimental evidence

Unhealthy food choice is one of the main causes of being overweight. Nutritionists blame a particular category of food: junk food. Several authors have proposed a fat tax for reducing the junk food demand, but others have demonstrated that these taxes must be very high in order to be effective. Therefore, a warning label about calorie content may be an alternative way to reduce the consumption of junk food. In this exploratory study, using students as respondents, a high‐calorie warning label is explored with an incentive compatible valuation method. The results indicate that a high‐calorie warning label has little effect on respondents’ choices, even when they have no prior familiarity with the food.     

Exploring the nutrition and lifestyle knowledge,attitudes and behaviour of student home economics teachers: baseline findings from a 4‐year longitudinal study

It is widely acknowledged that obesity linked with reduced exercise contributes to health problems, and that, conversely, individuals who embark on weight reducing diets may become deficient in key nutrients. It is often advocated that these problems, which can be grouped together as poor dietary practice, be tackled through education. This study attempts to examine the relationship between nutrition education and lifestyle behaviours in a select group of third level students. The Irish Home Economics curriculum aims to teach secondary school pupils about nutrition and lifestyle practices conducive to health. However, the attitudes and lifestyle practices of those teaching this subject have never been examined in Ireland. The purpose of the present 4‐year longitudinal study, whose first year findings are presented here, is to investigate the nutrition and lifestyle knowledge, attitudes and behaviours of a cohort of Irish student home economics teachers over the 4 years of their Bachelor of Education (Home Economics) degree course. The study was designed to explore possible changes in knowledge, attitudes and practices over the course of their professional education. Nutritional knowledge was measured using a 220‐question adapted version of the test devised by Parmenter and Wardle. Attitudes were measured using a questionnaire adapted from the Pan‐EU Survey on Consumer Attitudes to Physical Activity, Body‐weight and Health. Food, alcohol consumption and exercise were measured using a 7‐day reported dietary/exercise diary. Nutrient intake data were determined using dietary analysis. Weight, height and waist circumference were measured and body mass index (BMI) calculated. When starting college, student home economics teachers have broadly similar anthropometric, dietary and lifestyle characteristics to those of their contemporaries. Mean BMI was identical [24.4 kg/m² (SD 4.3)] to that reported in the North/South Ireland Food Consumption Survey (NSIFCS) for those aged 18–35 years, although energy intakes were significantly higher in the cohort of student teachers (P = 0.000). Thirty‐eight per cent were overweight or obese vs. 33.6% in the NSIFCS. Only 17% (n = 6) of students achieved an intake of 300 µg/day of folate as recommended by the Food Safety Authority of Ireland and only one the recommended intake of non‐starch polysaccharides (18 g/day). One in three students in this study smoke (16 of 48) and alcohol consumption was high. Only one student was very active. Students scored a mean of 55% (SD 8%) on the knowledge test, with similar scores attained for specific aspects of nutritional knowledge (i.e. food groups, constituents of foods, current dietary advice, nutrients, lifestyle practices). However, knowledge of nutrition definitions was weaker with a mean score of 31% (SD 8.6%). Students had a positive attitude towards food choice, the link between food and health and control over their own diet. Similar attitudes towards exercise, smoking and alcohol consumption were displayed despite students perceiving themselves as not having a balanced diet, having insufficient exercise and having regretted something done as a result of consuming alcohol. They appear to display optimistic bias in relation to health risks. These findings provide baseline data for the longitudinal study and indicate that those choosing to pursue a career as a home economics teacher in Ireland have similar nutritional and lifestyle characteristics to those of their contemporaries.     

Consumption of special diets among adolescents from 1999 to 2013: A population‐based study in Finland

Special diets are consumed as a treatment for diseases such as food allergies, diabetes, lactose intolerance, and coeliac disease. Lifestyle‐related diets, such as vegetarian, weight‐reducing, sports, bodybuilding, and low‐carbohydrate diets, can also be called special diets. The aim of this study was to examine the frequency of and reasons for special diet consumption as a therapeutic measure or as a lifestyle‐related choice among 12‐ to 18‐year‐old Finns. Nationwide cross‐sectional data were collected by mailed, self‐administered questionnaires in 1999, 2001, 2007, and 2013. The number of respondents varied from 3535 to 8219, and response rates ranged from 38% to 76%. Consumption of special diets, both for therapeutic purposes and as a lifestyle‐related choice, showed a significant increasing trend in 12‐ to 18‐year‐olds from 1999 to 2013 (p < .001). During the study period, the most frequently‐reported single diets in adolescents were vegetarian and lactose intolerance diets. However, a fluctuation trend was observed in the consumption of different lifestyle‐related diets. Further, a growing number of respondents, especially girls, reported simultaneous consumption of a combination of two or more therapeutic and/or lifestyle‐related diets. The reason(s) for choosing a therapeutic diet seems to stay constant during the studied period. In contrast, a wide variety of reasons such as health, wellbeing, body weight, ethical, and ideological reasons, and the avoidance of some specific foods were given for the consumption of lifestyle‐related diets. Our study results correspond well to the increased prevalence of common illnesses in Finland. Data also reveal the properties of special diet consumption among adolescents in the long run, and this highlights the need to further educate Finnish adolescents on nutrition literacy.     

The attitudes and nutritional knowledge of 11‐ to 12‐year‐olds in Merseyside and Northern Ireland

School is a major area for providing young people with nutritional knowledge and skills. In Northern Ireland home economics (HE) is taught to 11‐ to 12‐year‐olds. The 1988 Education Reform Act introduced the national curriculum and HE as a subject was effectively abolished in English schools, and key stage 3 pupils in England are taught nutrition in Science, Design and Technology and in the cross curricular theme of health education. The aim of the study was to compare the attitudes and nutritional knowledge of children in Merseyside, England (M) and Northern Ireland (NI). A questionnaire was designed, which examined attitudes to aspects of healthy eating and tested the subject's knowledge, practical and theoretical, on nutrition and healthy eating. Subjects aged 11–12 years were recruited (M: 541, NI: 128). The majority ‘understood and knew what to eat to have a healthy diet’, ‘liked the taste of healthy food’ and considered that ‘there were healthy foods at home’. However, a significantly greater number in Merseyside agreed that ‘their health will be affected in the future by what they eat now’ (M: 71%, NI: 54%, P < 0.01) and agreed that ‘they enjoyed cooking’ (M: 76%, NI: 56%, P < 0.01). Whereas more from Northern Ireland agreed that ‘they do not know what foods to eat to have a healthy diet’ (M: 14%, NI: 30%, P < 0.01), ‘that healthy eating involved “dieting” ’ (M: 29%, NI: 59%, P < 0.01) and agreed that ‘there are no healthy food choices at school’ (M: 23% NI: 42%, P < 0.01). More subjects from Merseyside disagreed that ‘healthy eating is a waste of time’ (M: 87%, NI: 77%, P < 0.01). The mean knowledge scores (correct answers) from Merseyside were significantly greater than from Northern Ireland (total score: M: 51%, NI: 43%P < 0.05; practical score: M: 58%, NI: 49%P < 0.05, theory score: M: 38%, NI: 31%, P < 0.05). The results indicate that the healthy food message seems to have been better learnt by children in Merseyside but results of surveys in Merseyside into eating habits suggest that many have not put this knowledge into practice.     

The influence of socio‐economic status on salt consumption in Northern Ireland

The long‐established association between high salt consumption and hypertension has led to calls for a reduction in salt intake. There is particular concern for the health status of Northern Irish consumers, who already have among the highest rates of coronary heart disease and stroke in the United Kingdom. With these concerns in mind, it is essential to establish the sources and patterns of salt consumption from discretionary and processed food sources before a reduction can be achieved. This study investigated differences in salt consumption patterns among consumers of varying socio‐economic status. Research consisted of a consumer questionnaire (n = 360) distributed within Northern Ireland. The results of the study revealed high discretionary salt usage and frequent consumption of processed foods among consumers of lower socio‐economic status. General observations from the questionnaire would suggest a need for improved health education for consumers in this group. The objective of health promotion should be to encourage a reduction in table and cooking salt usage and, in particular, in the consumption of highly salted processed foods. Enhanced product labelling is also encouraged to increase consumer awareness of current salt levels in food and of the availability of low‐salt foods. In addition, the results of this study advocate further development activity in the production of product formulations with low‐salt status.     

Parental eating messages and dietary guideline compliance of college students

The purpose of this study was to identify parental eating messages from the point of view of 340 college students and the relationship of these messages to dietary guideline practices. Four types of parental eating messages were identified: (1) threat or guilt, (2) picky eater, (3) food as health, (4) critical weight. Five types of dietary guide practices were identified: (1) fat meals and snacks, (2) vegetable–fruit, (3) sugar‐salt convenience food, (4) fitness–protein–carbohydrate, (5) fat add‐ons. The lack of association of parental eating messages with any of the dietary guideline factors suggests that messages are not affecting the food choices of these college students. Parental messages may in fact represent the way different cultures address eating, parenting and caring.     

Exploring the influence of family on adolescents’ seafood consumption choices

Seafood in the adolescent diet has many benefits, yet a number of adolescents do not consume the recommended levels. Despite this the consumption of seafood by younger consumers has received scant attention in the extant literature. Previous studies on adolescents’ food‐related behaviour tend to focus on general choice mechanisms or perceptions of food and mainly relate to fruit and vegetable intake. The present study seeks to address this gap through investigating the impact of family upon the consumption of seafood by younger consumers through exploring adolescents’ attitudes and behaviour in regard to eating seafood. Utilizing an exploratory qualitative methodology, seven focus groups of adolescents aged 13–19 years were conducted at two schools in South West England. Discussions covered a range of issues related to adolescent seafood consumption. The use of thematic content analysis found that the family, and parents in particular, exert high levels of influence over adolescents’ consumption of seafood both at home and when dining out. The parent who does the shopping and cooking has the greatest role. Sibling preferences and dietary choices also influence whether seafood is served in the home. Of value to researchers and management are the insights gleaned into the influences on adolescents’ attitudes towards and behaviour in regard to eating seafood. In particular, encouraging seafood consumption will rely upon interventions aimed at both parents and children and need to take into account adolescents’ diet and lifestyle preferences, while also acknowledging the influence of peers and the school food environment.     

Risk management behaviour by the Northern Ireland food consumer

The main criteria that consumers use during the decision‐making process when purchasing food have traditionally been a combination of prices, incomes, taste and social attitudes, with price being seen as the main determinant. However, in the past 10 years risk has become a ‘new’ criterion that can affect the consumer's decision whether or not to purchase a particular food item. The effect of the perception of risk has been observed during the numerous food scares in the last decade and in trends for the demand for foods that connote a health image. This research, carried out in Northern Ireland, looked at how consumers quantified and managed risk. The research involved 202 primary food consumers and identified the factors that were perceived to be important from both a societal and a personal perspective. Using principal component analysis techniques, societal food risks were seen as either processing or dietary, and personal food risks were seen as either extrinsic or intrinsic. Further investigation into the attributes of the personal risk using the same techniques revealed a three‐factor solution described as fear, involvement and newness. Although these factors cannot be used as predictors of the risk associated with a particular food, they help to describe and explain how the risk may be managed. The relationship between two of the factors, involvement and fear, provide a framework for understanding the way consumers manage their perception of the risk, particularly of high‐risk items. Consumer and scientific knowledge of the risk in question, and the degree of control over the risk were seen as important in the management of the risk in question. The conceptualization of the mechanism by which risks are processed and acted upon provides information regarding risk management and communication strategies that should be employed by educators, food retailers and government policy makers.     

Relationship between types of food choice motives and well‐being among young and middle‐aged Chinese adults

Food choice plays a vital role in people’s lives and well‐being, and this topic has received more research attention in recent years. The aims of the present research were to identify subgroups of participants who shared similar profiles of multiple motives for food choices, and examine differences across motive types on the well‐being of young and middle‐aged Chinese adults. Participants were 627 Chinese adults aged 18–58 years who completed questionnaire measures. The results of Latent Profile Analysis showed that based on the configurations among different motives for food choice, there were five profiles of food choice motives, corresponding to five types of Chinese adult consumers: unconcerned, mood oriented, weight control oriented, food enthusiast and health oriented. The food enthusiast consumers were more likely to include young adults with high‐income level and educational level, while the unconcerned consumers had a larger share of middle‐aged adults with low income. Results of ANOVA suggested that the types of food choice motives significantly predicted individuals’ well‐being. Specifically, the food enthusiast group had the highest level of well‐being, while the unconcerned group had the lowest level of well‐being. The other three groups had moderate levels of well‐being. The current study is the first to explore the potential influence of food choice motives on well‐being using a person‐centred approach, and the results have practical implications for public health authorities in developing effective interventions, for food companies in tailoring marketing campaigns and for individuals in optimizing food choices.     

Nutrition knowledge and lunchtime eating habits of secondary school children in Lothian

A total of 103 secondary school children attending five schools managed by Lothian Regional Council were surveyed to establish nutrition knowledge, attitudes and beliefs about healthy eating and their patterns of food consumption at lunchtime on schooldays. The results indicate that nutrition knowledge was surprisingly good and the children surveyed were proficient at identifying foods that were high in fibre and low in sugar, salt and fat. When questioned about their liking for foods, however, many identified foods that were characteristically high in fat, sugar and salt, and low in fibre. Examination of the dietary diaries kept at lunchtime confirmed that consumption of these types of foods was typically high, with very low consumption of fruit and vegetables being reported and high intakes of carbonated drinks, confectionery and chocolate. This conflict between nutrition knowledge and food choice patterns is discussed in the light of the probable future effects on health and the implications for health educators.     

The complexity of food choices in an everyday context

This study aims to understand the complexity of food choices in an everyday household context. The qualitative data are based on homemakers’ (n = 18) context‐specific accounts of their choice of milk brand, i.e. milk varieties with different fat contents (noted in a 4‐day qualitative food diary and a semi‐structured interview based on the diary). These accounts were considered an approximation of real food choices in households. The necessity of making compromises between contradictory expectations makes food choices, as well as milk brand choices, problematic. The homemakers' accounts involve various levels affecting household activities. At the individual level, the most important motive of choice is the taste and practical use of a product. At the level of households, the traditions stemming from one's childhood and the social aspect of acknowledging other family members’ taste preferences are important. The influence at the level of society and culture leads towards healthier choices, e.g. by providing examples of new, healthier food habits. Here, the special nature of everyday knowledge is emphasized as context dependent. This provides a complementary view to the more traditional, cognitive views of studying the relationship between knowledge of nutrition and food choices. Choices are determined not only by stimulus, cognition or societal structures, but are also constrained by everyday conditions, as well as by the activities of other people.     

Health motive and the purchase of organic food: A meta‐analytic review

There are many empirically determined influential factors known to control the organic food purchase behaviour. Of these known factors‐ health, product quality and concern for natural environmental degradation are seen as the major motives behind the organic food purchase. We, therefore, attempted to investigate the most prominent reason(s) for buying organic food, using the meta‐analyses of studies published during the last 25 years as our basis for conviction. Multilevel meta‐analyses was applied to the studies in review, in order to find the major reason(s) for the purchase of organic grocery, milk, fruits and vegetables. Although the three motivational factors mentioned above have been echoed throughout the history of organic food purchase research, the health factor has always topped the priority chart. The study in its overall empirical scale contributes to managerial implications and sets an agenda for future research.     

Taking care of you and me: How choosing for others impacts self-indulgence within family caregiving relationships

Consumers frequently make choices for family members they take care of or from whom they receive care (e.g., their children or partner), yet marketing research has given little attention to how these other-oriented choices might impact the chooser’s self-indulgence. In this research we consider familial caregiving relationships as a relevant and ubiquitous context of other-oriented choices and identify the role of the chooser (i.e., caregiver versus care-receiver) as an important moderator that determines when virtuous other-oriented choices within caregiving relationships lead to licensing and when they encourage consistent virtuous consumption behaviors.Three studies demonstrate that making virtuous food choices for others affect the chooser’s subsequent self-regulatory behavior in two ways: After making a virtuous choice for a care-receiving other (e.g., a young child), caregivers (e.g., parents) are more likely to license, and thus to subsequently self-indulge (Study 1, 3). In contrast, care-receivers are more likely to act consistently with an initial virtuous choice for the caregiver and thus are less likely to self-indulge (Study 2, 3).Our findings extend research on moral licensing and consistency effects by demonstrating that—within familial caregiving relationships—the degree to which one receives and provides care may determine when choosers engage in licensing and when they act consistently with an initial virtuous other-oriented choice.     

To Choose (Not) to Eat Healthy: Social Norms,Self‐affirmation,and Food Choice

With the rise of obesity in America, especially within the African‐American community, it is essential to identify strategies to encourage healthier food choices. Limited research has examined what, apart from socioeconomic indicators and targeted marketing, affects African Americans’ food choice. The current research explores how a self‐focus or racial group‐focus, in the absence of explicit eating‐norm primes, social influence, and identity threats, affects food choices and this varies by race. A group‐focus leads African Americans (Caucasians) to demonstrate unhealthy (healthy) food choices. On the contrary, a self‐focus leads African Americans to demonstrate healthier preferences while there is no change in Caucasians’ food preferences. Additionally, the current research shows how self‐affirmation, in the absence of threat, can be an effective mechanism for behavior change, for both African Americans and Caucasians. Affirming valued self‐attributes, after a group‐focus, leads to healthier food choices for individuals of both races. These findings are important as they may help identify ways to increase healthier nutrition choices in general and specifically for African Americans. Potential marketing strategies are discussed.     

Determinants of how individuals choose,eat and waste: Providing common ground to enhance sustainable food consumption out‐of‐home

The transformation of food consumption in wealthy economies is regarded as an essential measure to reach global sustainability goals. However, existing policies and research activities to change food consumption in the increasingly relevant out‐of‐home sector relate to a wide set of options on how to influence behaviours and may be criticized to lack a general focus. Against this background, our study provides a structured review of the existing research body on the determinants of individuals’ food choices and food consumption out‐of‐home. It structures the various research approaches and findings for 110 selected papers according to a general ecological framework where personal, social and environmental determinants for food behaviours are considered. By providing a collective overview and linking results for different behavioural aspects and settings, this study supports a more general understanding of consumer food behaviour in out‐of‐home settings. Consequently, it also provides a means to identify research gaps and to suggest relevant aspects for future research to draw from the combination of findings and to enhance sustainability in food consumption.     

Reduced‐fat foods: the shopper’s viewpoint

The inclusion of reduced‐fat foods in the daily diet affords consumers the potential to reduce overall dietary fat. Nevertheless, despite an increased range of these food products throughout the market, there has remained a lack of widespread consumer acceptance. The aim of the study was therefore to understand why consumers choose or reject reduced‐fat foods. Ninety consumers were interviewed by means of a qualitative approach within food retail outlets in the United Kingdom. Thematic content analysis indicated that uptake or rejection of these products is influenced by health concerns, ‘goodness of fit’ with individual dietary health strategies, the preferences of different household members, perceived sensory properties and scepticism towards these products. The results imply a need to explore and innovate ‘natural’ fat substitutes and to improve the sensory quality of reduced‐fat products. Further research is required to determine how these foods are used within the household and incorporated within the overall diet. Policy must seek to restore consumer trust in reduced‐fat food products and the food supply generally.
