Sustainability Perception of Italian Consumers: Is it Possible to Replace Meat, and What Is the Best Alternative?

Growing worldwide food demand with its environmental impacts requires a reshaping of food consumption. This study aims to evaluate the degree of Italian consumers' awareness of sustainability and whether protein alternatives to meat could be accepted. A cross-sectional survey was carried out on a group of 815 respondents, representative of the Italian adult population for geography, gender, and age, using multivariate analysis together with cluster analysis. Lack of awareness of the consequences of food choices on the environment was found in 45% of respondents, and 51% reduced their consumption of meat. Typical foods of the Mediterranean diet (84% legumes 82% eggs, and 77% fish) were selected as the preferred sources of protein to replace meat, while insects and insect-based products were less accepted (67%). The importance of meat is the latent factor that explains more than 50% of the common variance observed in the factor analysis. The cluster analysis confirmed the importance of meat for Italian consumers, emphasizing other aspects of the sustainability of food choices. Cluster 1 (25.6%) considered meat very important. Two out of five clusters (clusters 2 and 3, 38%) considered meat replaceable in the diet, and cluster 4 (31.3%) included meat consumers that were willing to be sustainable. Cluster 5 identifies the "unsustainable consumers" (5.7%). In conclusion, besides the perceived importance of meat, there is room for recommendations for its reduction by proposing alternative foods already present in the Mediterranean diet.

Characterization of household food waste in Italy: Three year comparative assessment and evaluation of seasonality effects.

In the present paper, the results of the first comparative assessment of household food waste in Italy are reported with a timeframe of three years coupled with an evaluation of seasonality effects. To pursue the aim of Sustainable Development Goal 12.3 to halve consumer food waste by 2030, the Italian Observatory on Food Surplus, Recovery and Waste carried out two surveys in 2021 (July and November) to characterize household food waste and to evaluate the seasonality effects. Data were collected with a validated questionnaire. For monitoring purposes, data collected in July 2021 were compared with those collected in July 2018. In three years, waste increased from 187.2 to 203.8 g per capita per week (p = 0.00). Fresh foods such as fruits and vegetables, bread, milk, yogurt, and non-alcoholic beverages, were the most wasted. In July the level of waste was higher for fruit (p = 0.00) while in November was higher for potato products (p = 0.04), pasta (p = 0.00), rice (p = 0.04), legumes (p = 0.01), and soups (p = 0.04). Data collected in July 2021 showed that retired people (p = 0.04), families with children (p = 0.01), particularly young children (9-13 years old) (p = 0.02), wasted less while who live in large town areas (p = 0.00), people with self-perceived limited monetary resources (p = 0.01) and mono-component families (p = 0.00) wasted more. The findings of the present work showed that there are specific population groups that wasted more with a gap between the intentions and the actions. The present data have a particular value posing the roots for the establishment of a food waste surveillance system in Italy.
