Diminishing household food waste (HFW) remains a challenge, requiring deeper and holistic understanding of individuals actions to improve prevention strategies. Using the Theory of Planned Behaviour (TPB) to understand attitudes generating waste, the present study explores the total volume of HFWand food groups to consumers HFWbehaviour. An initial survey of 1764 respondents in Brazil provided data on food consumption habits. A subsequent digital food waste journal collected data (and pictures) in 686 households to measure and categorize waste. Results show a high volume of HFW in Brazil?128.88 kg/household/year (or 41.7 kg/person/year)? with no significant differences associated with demographics (social class or location). Food categories resemble the Brazilian dailymeal,with rice, bean, and high-priced animal protein among the top five groups.However, the percentage of the wasted food groups differ completely from the consumed food groups. The most relevant attitudes towards HFW are ?food for all,? the quest for ?fresh food? and ?taste?, while taste and not having too much food were significant predictors of HFW. Although the amount of HFW is amidst the highest levels found in the literature, 94 % of participants consider avoiding waste as highly important. A probabilistic analysis to assess the distribution of HFW level showed a log-normal distribution, with high probability of low levels of food wasted, combined with low probability of large volume. In this context, TPB partially explains HFW behaviour, limited to frequent, low volume episodes, but does not explain occasional high-volume events. In practical matters, these results draw attention to low frequency events with significant impact in the amount of wasted food. In Brazil, there is a 5 % chance of households wasting >434.65 g/day. The value of the results lies in showing the need to implement different strategies to mitigate HFWwhen rare, high-volume events occur.
