The purpose of this study is to investigate how the different generations of consumers behave in the field of healthy and quality food consumption, considering their perceptions about healthy attributes and healthy eating style, what are the main trusted sources influencing consumption or the attention towards healthy and quality food, how do they behave towards healthy and quality foods and which benefits and barriers affect their consumption.

Data for this study were obtained from a questionnaire survey carried out over a six-month period in 2021. The questionnaire was administered online. The sampling procedure was based on a convenient non-random sampling method applied to the Italian population aged between 18 and 75 years old. The data collection process resulted in 1,646 completed questionnaires.

The results show that, in line with the theory of generational cohorts, each generation has its own specificities regarding food behaviour. The study reveals a highly sensitive approach towards healthy and quality food consumption from both Z-ers and the Baby Boomers, whilst X-ers are quite aligned with the other generations. Millennials show specific, sometimes contradictory, attitudes and habits.

The present results offer new insights into the analysis of healthy and quality food consumption, highlighting significant differences amongst generations, which can inspire public and private intervention aimed at encouraging the overall attention and consumption of healthy and quality food with related implications in terms of society's well-being and longevity improvements.

This study aims to identify the key factors that influence household pro-environmental behaviors (HPEBs) and explore the differences caused by the same influencing factors between household waste management behavior (HWM) and household energy-saving behavior (HES).

A meta-analysis was conducted on 90 articles about HPEBs published between 2009 and 2023 to find the key factors. HPEBs were further categorized into HWM and HES to investigate the difference influenced by the above factors on two behaviors. The correlation coefficient was used as the unified effect size, and the random-effect model was adopted to conduct both main effect and moderating effect tests.

The results showed that attitude, subjective norms, and perceived behavioral control all positively influenced intention and HPEBs, but their effects were stronger on intention than on HPEBs. Intention was found to be the strongest predictor of HPEBs. Subjective norms were found to have a more positive effect on HES compared to HWM, while habits had a more positive effect on HWM. Furthermore, household size was negatively correlated with HWM but positively correlated with HES.

The same variables have different influences on HWM and HES. These results can help develop targeted incentives to increase the adoption of HPEBs, ultimately reducing household energy consumption and greenhouse gas emissions and contributing to the mitigation of global warming.
