Food waste contributes significantly to greenhouse gas emissions. Reducing food waste can help address climate change and its negative impacts on food security. Analyzing the effect of nutrition education and food management interventions on food waste and household food security. This study used a pre-post experimental research design using 100 respondents, namely housewives who were taken using the Stratified Random Sampling technique conducted in December 2023 - September 2024. Data were collected pre and post-intervention, where the intervention was balanced nutrition education with nudging reinforcement and food management education for 12 weeks. Hypothesis testing using T-test and Ancova. Balanced nutrition intervention with nudging reinforcement can affect reducing food waste. However, in order for the implications for food security to be better, the balanced nutrition intervention (with nudging reinforcement) must be accompanied by food management behavior (36% reduction in FW, 14% increase in food consumption quality, 3% food expenditure efficiency, and 5% increase in population food security). Balanced nutrition interventions using nudging can reduce food waste and improve food security.
