“…In summary, cooking behavior tended to partially mitigate the disparity in healthful eating habits due to economic status and spare time. Previous studies suggested positive associations between socioeconomic status, such as economic status and spare time, and dietary habits [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][40][41][42]. Additionally, they illustrated that cooking behaviors can lead to healthful eating habits [20][21][22][23][24][25][26][27].…”

“…The participants used five choices to rate subjective spare time, namely, somewhat much, neither, somewhat less, and less [28]. Although subjective spare time was not tested for criterion-related validity, previous studies confirmed a significant inverse association with household food waste [40]. In addition, previous studies reported an association between lack of time and unhealthy eating habits [41,42].…”

This study investigated the intersecting influence of socioeconomic status and cooking behavior on dietary habits using nationwide Japanese data. The study measured the frequency of balanced meals and breakfast intake as indicators of healthy eating habits and used subjective economic status, subjective spare time, and cooking behavior as the independent variables. It employed multivariate logistic regression analyses to elucidate the relationships among these variables. The results demonstrated that even among economically poor or time-constrained individuals, those preparing meals from ingredients were more likely to eat balanced meals and breakfast than those relying on commercial food or rarely cooking. This finding suggested that cooking behavior can mitigate disparity in healthful eating due to socioeconomic conditions. The study added new insights into the impact of combining socioeconomic status and cooking behavior on dietary habits, which highlights the potential of promoting cooking behaviors, such as teaching cooking skills, as a strategy for reducing socioeconomic dietary disparities.

“…Many of these studies highlighted behaviours that can increase or decrease FW. Meal planning and shopping lists can reduce FW [52][53][54][55][56][57][58][59][60], cooking or serving too much food can increase this phenomenon [26,53,54,[61][62][63] as well as frequency purchase could increase FW [22,58,64].…”

Factors affecting food waste: A bibliometric review on the household behaviors

Sustainability issues such as food insecurity, climate change, land degradation, economic development and food waste are the actual most important challenges at the global level. Among them, the food waste (FW) challenge has a great magnitude, emphasizing the importance of examining this issue. Specifically, there is a need to focus on the household level. Thus, this study aims to investigate and identify the main factors influencing FW household behaviors on which policymakers and stakeholders could outline specific and sustainable strategies. Starting from a large number of published studies on this subject with a similar aim but focusing on specific Countries or contexts, the goal of our study is achieved through the implementation of a systematic literature review followed by a bibliometric review using the VOSviewer software. The selected query generated a total of 235 matching papers from which only 111 papers were collected for the bibliometric review because of the inclusion criteria. The analysis showed the existence of four major research strands: the largest one analyses the antecedents of behavior during food management, including the implementation of the Theory of Planned Behavior (TPB). Other detected topics are the economic impact of FW, the effects generated by the Covid-19 pandemic on consumer behaviors, and finally, the environmental and social effects of FW. The objective of this study is to investigate and identify the main factors influencing FW household behaviors. The obtained output represents useful information for policymakers and stakeholders to outline specific and sustainable strategies to reduce FW.

“…One study analyzed the factors contributing to food waste in Japanese households using categorizations based on large cities, small cities, and rural areas. The results revealed that individuals with "agricultural experience" had significantly lower rates of food waste in urban and rural areas [25]. Mobile application technology has the potential to reduce food waste.…”

“…Research on food loss and waste began in the late 1980s; since 2005, research on this issue has become more widespread globally [9]. In recent years, research on food waste at the consumer end has mainly focused on five areas; anti-food waste policies and methods [10][11][12][13], quantity measurements of household food waste [14][15][16][17][18], analyses of the harms of food waste [18][19][20], analyses of the factors influencing household food waste [21][22][23][24][25][26], and methods and techniques to deal with food waste [27,28]. In the area of anti-food waste, a study on anti-food waste policies explored the influencing factors of policy implementation and found that the effective implementation of policies is closely related to the active participation of supermarket managers.…”

Food waste has become a pressing global issue in recent years. In China, the issue of food waste has become increasingly severe. As a provincial capital city, Harbin is also a major agricultural city in China with distinct urban and rural features. This paper uses Harbin as a case study to evaluate different strategies for preventing and reducing food waste based on these urban–rural differences. This research is based on official data on household food waste in urban and rural areas of Harbin, as well as data collected from 333 telephone surveys through stratified random sampling. Independent t-tests, one-way analysis of variance (ANOVA), and logistic regression analysis were used to analyze the survey data, followed by a review of existing food waste policies and strategies. Our findings show that Harbin has had a positive response in adhering to national anti-food waste policies. However, its implementation has not been effective. There is a continuous increase in food waste generation. Moreover, gender, level of education, and household annual income have a significant impact on residents’ food waste habits and there are significant differences between urban and rural areas in terms of “eating out” and “ordering food ingredients”. The average daily amount of food waste generated by urban households is 3216.31 g, which is 2.4 times that of rural households. There are also differences in the causes of food waste between urban and rural residents due to different diets and eating habits. As a result, feasible and effective policy recommendations have been proposed to reduce food waste in response to these urban–rural differences.
