Food waste produced in homes represents the largest fraction of food waste generated along the food chain. Therefore, adequate prevention measures based on the quantitative and qualitative dimensions of the problem need to be put in place to reduce waste. The objective of the review was to identify areas of interest in relation to the food waste in households, considering the family unit as a whole as well as individual family members. Quantifying the problem is an important aspect in order to know its scope and dimension, but prevention also involves knowing the causes in a home. This is a complex issue, which, on a family level, is related to socioeconomic status, educational level, composition and number of members of the household as well as culinary and buying food habits. Individual variables such as age, sex, values, awareness, lifestyle and time spent on food preparation were included to characterize consumers. The focus of the problem is also important because most consumers consider food waste from a social perspective, without being aware of the serious environmental and economic problems. Habits and customs of consumers are considered the leading cause of food waste in homes and knowledge of this issue raises consumer awareness as a preventive tool.
