One third of all the food that is produced and edible around the world gets thrown away (WWF, 2014). Households are the main source of food waste according to the Swedish National Food Agency, each year a person throws a total of 33 kilograms of food and drinks in their homes (Livsmedelsverket, 2023). The purpose of this study is to contribute with knowledge about the level of food literacy amongst young adults in Sweden and how it affects their food waste management. A descriptive survey was used by the author as the data collection method to gather general information about what the individuals directly know and how they feel and behave regarding food waste. The results show that the city-based young adults in the Stockholm region indicate certain aspects of food literacy but that there are still improvements to be made. Indicators showing self-perceived food knowledge and positive emotions and attitudes regarding pro-environmental behaviour were found, but indicators of food literacy behaviour were not as substantial. Overall, the findings of this study suggest that young adults face significant challenges with regard to acquiring and using food literacy and that improvement needs to be made in the school education programmes and more engagement in the home for they are environments where the people get introduced for the first time to cooking and food waste management.
