Factors Affecting the Extent to which Consumers Incorporate Functional Ingredients into their Diets

This study considers the factors that explain the consumption of food and beverages with functional ingredients to avert or offset health problems. We use an instrumental variables Poisson regression model to deal with the endogeneity of perceived health status in functional ingredient use. The first stage results indicate that perceived health status is associated with attitude towards functional foods, food consumption motives and information seeking and being female. The second stage results suggest that individuals who consume more functional ingredients tend to have a positive attitude towards functional foods, are novelty‐seeking, female and older. As expected, consumption of functional ingredients is more likely when consumers’ self‐reports indicate that they are aware of functional foods’ nutritional value and the link with their own health. Consistent with previous research, most of the socio‐demographics are poor predictors of functional ingredient consumption.     

Linking Consumers’ Food Choice Motives to their Preferences for Insect‐based Food Products: An Application of Integrated Choice and Latent Variable Model in an African Context

Consumers’ attitudes, perceptions, personalities and motives play important roles in shaping their food choices. These factors are not fully observed by analysts, so they should be treated as latent variables. A number of economic studies treat such variables as direct measures of consumers’ food choice behaviour, even though this might introduce measurement error and endogeneity bias. We investigate the latent link between consumers’ preferences and food choice motives (FCMs) in an African context. We use an integrated choice and latent variable (ICLV) model specification for data analysis to recognise the latent nature of the FCMs and address the measurement and bias problems. The data originate from an incentivised discrete choice experiment conducted in Kenya to elicit consumers’ preferences for insect‐based foods. Our findings show that consumers’ preferences and choices are influenced by their latent motivational orientation. The results illustrate the benefit of the ICLV approach in accounting for consumers’ latent preference constructs in food choice and valuation research.     

Dietary Globalization in Chinese Breakfasts

Demand for nontraditional foods is on the rise in China. Data from household surveys and consumer food diaries in Beijing, Nanjing, and Chengdu are examined to measure the effects of demographics on consumption of nontraditional food products. We focus on bakery and dairy products, two categories of foods that are rarely consumed in traditional Chinese breakfasts. We find that income, time constraints, and education positively affect the inclusion of nontraditional foods in the breakfast meal. Our results suggest that younger consumers are leading the transition to new global consumption patterns that integrate nontraditional foods into urban Chinese breakfasts. The implications of these findings for wheat and milk production and processing industries are discussed.     

Environmental Concerns and Food Consumption: What Drives Consumers’ Actions to Reduce Food Waste?

Consumer behavior and food consumption comprise the largest amount of waste in the food chain. This study aimed to identify the relationships among consumer environmental concerns, their awareness of food waste, demographics, and their food consumption. The findings suggest that food waste prevention is positively influenced by consumers' environmentally conscious buying, food waste awareness, bulk buying, frequency of home cooking, and age. Impulsive food purchasing, the frequency of eating out, and the number of people in the household negatively influence food waste prevention. Food policy makers and retailers should be involved in educating and encouraging consumers to minimize food waste.     

To Eat or Not to Eat: Seafood Consumption Habit Formation

Healthy development and nutritional sufficiency have long been linked to consumption of a well-balanced diet, especially in primary school age children. Seafood products have been identified as a key component of a healthy diet. The consumption habits of a balanced and sustainable diet in children needs to be examined while taking into account family and environmental factors which influence eating habit formation in young children. The family setting is the first place where children acquire examples and principles of their own eating habits. Therefore, this study explores the effects of family eating habits on seafood consumption habit formation in children. Seafood intake diaries, pictures of consumed meals, as well as in-depth interviews formed a pilot study which included four families. The collected results were thematically analyzed and underpinned by principles of the Theory of Planned Behavior, Stages of Change Model, and Social Cognitive Theory. The pilot study results revealed an array of attitudes and preferences, norms (e.g., religion and parental duty), perceived drivers (e.g., health benefits), and perceived barriers (e.g., affordability and availability) which influence the formation of sustainable eating habits in children. A range of strategies (internal and external) for assisting appropriate eating habit formation including consumption of sustainable seafood by children are discussed.     

Fragmented Food Habits and the Disintegration of Traditional Meal Patterns: A Challenge to Public Health Nutrition in Canada?

Abstract

This study examines the shifting patterns in meal consumption practices among Canadians and the sources of disruption of meal habits. It analyses the notion of breakfast, lunch, dinner, out-of-household consumption of food, cooking, and snacking which could be considered as disrupting eating habits. Meal skipping, primarily breakfast and lunch was common, particularly among women, as was consumption of food outside the home, particularly among lower income earners and respondents with lower education attainment. The findings of this survey suggest that contemporary Canadians are experiencing a disruption of meal times, a rise in the frequency of snacking and an erosion of the will or ability to prepare or cook meals at home. For many Canadians, the traditional notion of three-meals a day is becoming an ideal, rather than a daily reality. Fragmented food habits and the disintegration of traditional meal patterns represent a challenge to public health nutrition in Canada.     

Modelling the likely impact of healthy eating guidelines on agricultural production and land use in England and Wales

Quadratic programming techniques were applied to household food consumption data in England and Wales to estimate likely changes in diet under healthy eating guidelines, and the consequences this would have on agriculture and land use in England and Wales. The first step entailed imposing nutrient restrictions on food consumption following dietary recommendations suggested by the UK Department of Health. The resulting diet was used, in a second step as a proxy for demand in agricultural commodities, to test the impact of such a scenario on food production and land use in England and Wales and the impacts of this on agricultural landscapes. Results of the diet optimisation indicated a large drop in consumption of foods rich in saturated fats and sugar, essentially cheese and sugar-based products, along with lesser cuts of fat and meat products. Conversely, consumption of fruit and vegetables, cereals, and flour would increase to meet dietary fibre recommendations. Such a shift in demand would dramatically affect production patterns: the financial net margin of England and Wales agriculture would rise, due to increased production of high market value and high economic margin crops. Some regions would, however, be negatively affected, mostly those dependent on beef cattle and sheep production that could not benefit from an increased demand for cereals and horticultural crops. The effects of these changes would also be felt in upstream industries, such as animal feed suppliers. While arable dominated landscapes would be little affected, pastoral landscapes would suffer through loss of grazing management and, possibly, land abandonment, especially in upland areas.     

Agricultural production and children's diets: evidence from rural Ethiopia

We study the relationship between pre‐school children's food consumption and household agricultural production. Using a large household survey from rural Ethiopia, we find that increasing household production diversity leads to considerable improvements in children's dietary diversity. However, we also document how this nonseparability of consumption and production does not hold for households that have access to food markets. These findings imply that nutrition‐sensitive agricultural interventions that push for market integration are likely to be more effective in reducing under‐nutrition than those promoting production diversity.     

Food Preferences and Ethnicity

Policies to curb food imports in food deficit Sahelian countries have been unsuccessful. Sahelian countries are ethnically diverse and each group has demonstrated strong preferences for cereals and other foods. Yet, research on the consequences of expressed food preferences on food production, consumption, and importation is limited. In this paper, the effects of ethnic identity and income class on food consumption choices were investigated. The results showed that all consumers, use the same criteria in evaluating a given set of foods irrespective of ethnic group, or income class. Ethnic groups and income classes choose a given food basket, which maximizes their welfare, if the same criteria are used in making their food choices.     

Food Consumption Trends in the Pacific Rim

The growing affluence of the Pacific Rim countries has changed food consumption patterns. Diets in the region have become more diverse and well-balanced nutritionally. Western-style foods are becoming increasingly popular and available to people in the region. The rapid growth of fast-food chains and supermarkets present U.S. agricultural exporters with a myriad of opportunities for exporting food products to the Pacific Rim. Food producers who are willing to modify their products to the tastes of Pacific Rim consumers will have the most success. By reformulating food products and developing new packaging technologies more high-value foods can be sold in the Pacific Rim. U.S. food processors must also develop improved methods of processing traditional foods eaten by people in the region into more convenient forms. Finally, it is important for U.S. agricultural exporters to keep a close watch on the changing trends in food consumption in the region in order to stay competitive and increase their opportunities for entering new markets.

The Effect of Behavioral Contagion and Tie-Strength on Calorie Intake in Food Courts

Major contributors to the obesity epidemic are societal and result from sedentary lifestyles and consumption of high-calorie diets. Previous studies suggest that food choice behavior is socially transmissible. Hence, knowledge of the impact of social influence on calorie intake is critical to improve the understanding about the outcomes of policies related to healthful diets. There is the need to analyze the influence of social networks on choosing food in a public place. Thus, we interviewed groups of food court patrons in an all-you-can-eat college dining hall. Results show individuals dining in a group with at least one obese group member are consuming more calories from high-calorie foods and fewer calories from low-calorie foods. Food-related interactions in a group influenced food consumption. Hence, dining with obese peers likely increases calorie intake.     

The effects of food sales taxes on household food spending: An application of a censored cluster model

This study proposes a model of household food spending that accounts for zero censoring and can be applied to data collected through a clustered survey design to investigate the impact of food sales taxes on three groups: households who are eligible for and participate in the Supplemental Nutrition Assistance Program (SNAP), households who are eligible but do not participate in the program, and households who are not eligible for the program. We find that SNAP participating households are largely insensitive to grocery taxes and respond to restaurant taxes by shifting more of their food dollars towards at-home foods. Among households who are eligible for SNAP but do not participate in the program, grocery taxes reduce spending on foods purchased for at-home consumption, and thereby increase the amount of the total food budget allocated to away from home foods. This is concerning from a nutrition and health standpoint since away from home foods tend to be more calorie dense and nutritionally poorer than at home foods.     

National Food Consumption Patterns: Converging Trends and the Implications for Health

Worldwide, obesity almost tripled between 1975 and 2016 and is now prevalent in both rich and poor countries. Using annual food availability data produced by the Food and Agriculture Organisation of the United Nations (FAO) covering half a century in 118 countries, this article explores the diets that are central to the problem of obesity, identifying groups of countries with similar consumption patterns. Applying algorithms from the fuzzy clustering literature, five distinct consumption patterns are revealed whose dietary composition broadly corresponds to diets that we label ‘Western’, ‘Traditional’, ‘Mediterranean’, ‘Tropical’ and ‘Vegetarian’. Despite differences in dietary characteristics, all five share two common themes: rising total calories and declining healthiness, both of which are linked to the substitution of plant-based foods with food derived from animals. That the evidence points to a convergence on the ‘Western’ diet, the most obesogenic and least healthy of all the diets we consider, is a cause for concern. The key message is that in a future where people are predicted to live longer – but not necessarily healthier – lives, recent efforts to address the challenge are prescient, and as the results in the article imply, need to be heeded globally.     

Agricultural Commercialisation and Nutrition in Smallholder Farm Households

Commercialisation of smallholder agriculture is important for rural economic growth. While previous studies have analysed effects of commercialisation on productivity and income, implications for farm household nutrition have received much less attention. We evaluate the effects of commercialisation on household food security and dietary quality with a special focus on calorie and micronutrient consumption. We also examine transmission channels by looking at the role of income, gender, and possible substitution effects between the consumption of own-produced and purchased foods. The analysis uses survey data from farm households in Kenya and a control function approach. Generalised propensity scores are employed to estimate continuous treatment effects. Commercialisation significantly improves food security and dietary quality in terms of calorie, zinc and iron consumption. For vitamin A, effects are insignificant. Commercialisation contributes to higher incomes and increased nutrients from purchased foods, but it does not reduce the consumption of nutrients from own-produced foods. Enhancing market access is important not only for rural economic growth, but also for making smallholder agriculture more nutrition-sensitive.     

Diet transformation in Africa: the case of Ethiopia

Africa's food systems are changing fast amid rapid economic growth, emerging urbanization, and structural transformation. In this study, we use four rounds of nationally representative data from Ethiopia to document changes in household food consumption patterns over a period of unprecedented economic growth. We find that while the share of food in the total consumption basket is declining, food quantities and calorie intakes have considerably increased between 1996 and 2011. A decomposition analysis suggests that this was mostly driven by improvements in household incomes—a finding that is consistent across the calorie distribution. Also, the content of the food basket is changing with a gradual shift toward high‐value foods such as animal products, fruits and vegetables and processed foods. Overall, this diet transformation has important implications for the food security debate and for agricultural and food policy in the country.     

Fluid milk consumption in urban Qingdao,China*

This study relates the social‐demographic characteristics of urban Chinese consumers to their consumption of fluid milk. A Tobit model is estimated drawing on individual consumer survey data collected in urban Qingdao in China in 2005. The major results of this study indicate that fluid milk consumption in urban Qingdao is much higher compared to China's national level. The effect of increased income on milk consumption is positive, as expected. The expansion of modern food retailers also appears to play a positive role by facilitating consumers’ fluid milk consumption and influencing their food shopping patterns. The young and old consume significantly more fluid milk than the middle‐aged. Health consciousness of the elderly and the openness of youth to new foods appear to be fuelling these consumption patterns. If the findings of this study apply to other urban regions in China, then as urbanisation continues so also will the trend of increasing fluid milk consumption in China.     

Food Consumption Patterns and Nutrition in Urban Java Households: The Discriminatory Power of some Socioeconomic Variables

Food consumption patterns are undergoing substantial change in many countries as economic development proceeds. The trend is a move away from traditional cereals towards higher-value and higher-protein foods. Explaining such changes only in terms of traditional economic variables can lead to biased estimates of income effects and perhaps biased projections of food demand. Household survey data from Indonesia are used to measure the importance of several socioeconomic variables in explaining differences in household food consumption patterns and nutrition. Household expenditure and the level of women's education are shown to be the most influential in this explanation.

Consumer Motives and Purchase Preferences for Organic Food Products: Empirical Evidence From a Consumer Survey in Bangalore,South India

ABSTRACT

Consumer organic food choice motives and purchase preferences were studied in a structured quantitative survey (N = 201) in Bangalore, with the aim of identifying consumer segments based on these motives and preferences. Further, sociodemographic differences between the clusters were studied. Face-to-face interviews were used to sample the data, which were analyzed with factor and k-means cluster analysis (SPSS 16.0). Five latent factors were identified based on the motives, representing a set of consumer concerns labeled here as “food phobia” (health),” “environment,” “humanity,” “healthy eaters,” and “control.” Further, three clusters emerged from these motives representing 38%, 37%, and 25% of the sample size. The factors differ in terms of variance. Here, the records of perceived healthiness (food phobia) were the most important element, explaining 18.37% of the total variance. These clusters were differing in terms of the level and order of motivations. The health factor was a most important motive in two clusters, followed by environment. Further, humanity was the most important motive for the third cluster. This may reflect a heterogeneous nature of consumers in study area. Additionally, five clusters were identified based on the preferences, and profiles of these clusters differed in terms of sociodemographic factors and consumption pattern. Segments were identified based on motivating factors and preferences, and linking them with food choice motives and products preference provides the input needed by marketing professionals and policy makers to calibrate more efficient marketing strategies to better focus and position their products and design their communication strategies for target segments.
