Changing the everyday food-related behaviours of consumers is a critical part of tackling the global food waste challenge. Comprehensive frameworks of household food waste and consumer behavior are needed to guide the development of targeted interventions and future research agendas. This study systematically reviews food waste and behaviour studies from developed nations to provide an overview of the current research field. It uses a multi-level perspective to organise the various factors influencing food-related behaviour and proposes a new, multi-level, framework of consumer behaviour and household food waste. A novel addition to the field, the framework gathers factors at micro (individual), meso (household), and macro (external to the household) levels and argues that behaviour and food waste emerge from their interactions. Our review also reveals a research domain with disciplinary and methodological 'bald spots' and an over-emphasis on individual level factors. A multi-level research agenda focusing on under-explored factors and interactions between factors across levels is presented, and consideration given to multi-level interventions that support consumer behaviour change to reduce household food waste., (Copyright © 2020 Elsevier Ltd.

Behavioral theories have much to offer researchers and policy makers who seek sustainable resource management within households. However, much research on household resource consumption applies theories of the individual to understand the behavioral patterns of what are very often groups of people cohabiting in a particular dwelling. This misalignment of levels of analysis leads to erroneous empirical results and conclusions, and thereby less effective policy and management actions. We address this issue by first detailing the nature of the problem; illustrating its pervasiveness in research on resource consumption behaviors; offering some ways forward by drawing on research on group dynamics; and exploring new ways of thinking about some existing concepts in resource consumption and conservation with the goal of developing insights from a household-level perspective. We suggest that researchers seek a multi-level understanding of consumption and conservation in future research, as this could lead to theories and evidence to support group-level interventions that target behaviors in a household setting, which is likely to be more effective than existing individualistic approaches., (Crown Copyright © 2020.

What does it take to increase the consumption of meat substitutes and attract new consumers? We identified main barriers and drivers by a consumer survey (n=553) in the U.K. and the Netherlands. Person-related factors (food neophobia and food choice motives) and product-related attitudes and beliefs towards meat and meat substitutes were compared between non-users (n=324), light/medium-users (n=133) and heavy-users of meat substitutes (n=96). Consumer acceptance was largely determined by the attitudes and beliefs towards meat substitutes and food neophobia. Key barriers for non-users and light/medium-users were the unfamiliarity with meat substitutes and the lower sensory attractiveness compared to meat. In addition, non-users had a higher tendency to avoid new foods. Hence, the less consumers were using meat substitutes, the more they wanted these products to be similar to meat. Although non-users and light/medium-users did recognize the ethical and weight-control aspects of meat substitutes, this was obviously less relevant to them. Actually, only heavy-users had high motivations to choose ethical foods, which explains their choice for meat substitutes. In order to make meat substitutes more attractive to meat consumers, we would not recommend to focus on communication of ethical arguments, but to significantly improve the sensory quality and resemblance to meat., (Copyright © 2011 Elsevier Ltd.

The aim was to investigate socio-demographic characteristics, and attitudes to food and health of vegetarians, non-vegetarian consumers of meat substitutes, and meat consumers in The Netherlands. The sample used for this study (participants > or =18 years) was taken from the Dutch National Food Consumption Survey, 1997/1998. Vegetarians (n = 63) and consumers of meat substitutes (n = 39) had similar socio-demographic profiles: higher education levels, higher social economic status, smaller households, and more urbanised residential areas, compared to meat consumers (n = 4313). Attitudes to food were assessed by the food-related lifestyle instrument. We found that vegetarians (n = 32) had more positive attitudes towards importance of product information, speciality shops, health, novelty, ecological products, social event, and social relationships than meat consumers (n = 1638). The health consciousness scale, which was used to assess attitudes to health, supported earlier findings that vegetarians are more occupied by health. Food-related lifestyle and health attitudes of meat substitute consumers (n = 17) were predominantly in-between those from vegetarians and meat consumers. The outcome of this study suggests that in strategies to promote meat substitutes for non-vegetarian consumers, the focus should not only be on health and ecological aspects of foods.
