This article aims to identify antecedents of food waste among lower‐middle class families – a paradox, given the financial constraints this population faces. The importance of this research is evident in escalating environmental pressures for better use of our planet's scarce resources. Given that most of the world is low‐income, any behavioral change in this population is likely to have a considerable impact. Empirical data were collected from 14 lower‐middle income Brazilian households, based on observations, in‐depth interviews, photographs and a focus group (n = 6). Five major categories of food waste antecedents were identified: (1) excessive purchasing, (2) over‐preparation, (3) caring for a pet, (4) avoidance of leftovers and (5) inappropriate food conservation. Several subcategories were also found, including impulse buying, lack of planning and preference for large packages. Surprisingly, findings show that strategies used to save money – such as buying groceries in bulk, monthly shopping trips, preference for supermarkets and cooking from scratch – actually end up generating more food waste. This mitigates the savings made during the purchasing phase.
Drawing from previous studies, this review proposes a research agenda in regard to household food waste, a neglected topic within the field of consumer behavior. This phenomenon has remarkable social and environmental relevance when one considers that it occurs at the end of the food chain, and thus, wastage at this stage implies losses of resources required for food production. This study aims to provide a framework and solutions for conducting future research in this area. Academic opportunities identified suggest that further theorizing is needed related to consumer food waste, in addition to studies aimed at testing the impact of communication initiatives on behavioral change and at providing a standardized methodology to measure consumer food waste.
This qualitative study, grounded theory oriented, identifies familial affection and preference for abundance as major drivers of wasted food in lower-middle income American families. These positive intentions provide an improved understanding of household food waste, a problem with high environmental impact and moral implications. Based on empirical data collected with twenty caregivers via in-depth interviews, observations, and analysis of photos, this study provides novel explanations, such as on how stockpiling comfort foods in abundance -a form of both boosting positive self-emotions and showing affection for kids -can promote more wasted food. Other antecedents identified include multiplicity of choices, convenience, procrastination and unplanned routines. In sum, this research identifies a negative outcome of affection and food abundance in the family context, while providing a theoretically relevant general framework to help understand the food waste phenomenon. Authors suggest increasing the awareness of nutritional gatekeepers through behavioral economics principles.
By 2017, Brazil seems to have finally awakened to the problem of food loss and waste. In this article, we resume the topic started in the article "Postharvest losses of perishables in Brazil: what do we know so far?" published earlier this year, but now with an emphasis on food losses and waste (FLW). We divided this article into four sections: (a) search for scientific publications on postharvest losses (PHL) and food waste (FW) in Portuguese; (b) social classes and food consumption in Brazil and household food waste; (c) the national legal framework on FLW; and (d) current food security policies and civil society actions on FLW. Google Scholar searches yielded 46,100 records for FW and 16,100 for PHL, but only 37 and 19 records, respectively, when the searches were restricted to the title of the papers. There is a clear division of subjects: PHL is more related to Agriculture and Economy and FW to Health, Nutrition and the Environment, and reasons and consequences are discussed. Food consumption and waste in Brazil must take into account the great social heterogeneity and high income inequality, as well as some unexpected driving cultural reasons. About 30 bills related to food waste have been discussed in the Brazilian Congress since 1997, with a low expectation of approval in the short term. In the absence of a regulatory framework to reduce losses and facilitate the donation of food, society has found its own way of dealing with the problem. Some initiatives are presented here, along with some governmental food security policies which had positive impacts in reducing FLW, such as National School Feeding Program (PNAE), food banks and popular restaurants. Some international movements are also beginning to gain strength in Brazil, e.g., the purchase of fruits and vegetables outside of aesthetic standards, "SaveFood Brasil", "Slow Food", among others. These are all put in perspective.
