Food waste, climate change, socioeconomic considerations, agricultural policy, access to wholesome foods, food sovereignty, and food security are some of the major topics covered in the literature. Because of this, ensuring food security is not a straightforward issue that can be resolved by changing a single variable; rather, it necessitates the combination of numerous multidisciplinary approaches. Therefore, the goal of this study is to pinpoint the major gaps in the literature, such as a lack of attention to the perspectives of marginalized groups and a lack of investigation into the connections between food security and other global issues. The article offers suggestions for future work, including how to prioritize understudied subjects, incorporate other points of view, and enhance data collection techniques. As a result, it can be a useful starting point for linguists who want to research related topics. This study offers new researchers and practitioners a place to start to learn more about the rapidly, growing field of sustainable food security. Future research can also address these gaps and enhance food security globally for a sustainable future. This will require the participation of new scholars, policymakers, and practitioners.

Introduction Food security is defined as a state where all individuals have physical, social, and economic access to sufficient, safe, and nutritious food that meets their dietary needs and preferences for an active and healthy life. It plays a crucial role in achieving the United Nations’ Sustainable Development Goals (SDGs) related to poverty reduction, hunger eradication, and sustainable agriculture. Food security also has a significant impact on health outcomes, as poor nutrition can lead to malnutrition and diet-related chronic diseases. However, with an estimated 690 million people experiencing hunger and malnutrition in 2019, it is considered one of the most significant global challenges of the 21st century (FAO, 2019). To make matters worse, the COVID-19 pandemic has further exacerbated food insecurity, with an additional 132 million people experiencing hunger in 2020 (Clapp & Moseley, 2020). In addition, food insecurity can lead to social unrest, political instability, and conflict. Recent research has highlighted the importance of addressing food security through a multidimensional and interdisciplinary approach. For instance, there is a growing recognition of the role of food systems in achieving food security and the need to transform them to be more sustainable and resilient (IPBES, 2019). There is also a need to address the social and economic factors that contribute to food insecurity, such as poverty, inequality, and conflict (FAO, 2019). Thus, food security is a critical global issue that impacts human health, economic development, and social stability. It is essential to address this challenge through a multidimensional and interdisciplinary approach that considers the complex interactions between food systems, social and economic factors, and environmental sustainability. The current state of food security literature highlights the complexity of the issue and the need for a multidimensional and interdisciplinary approach. Recent research has identified key issues related to food security, including food waste, climate change, socioeconomic factors, agricultural policies, access to healthy food, and food sovereignty and security (Alexander, Brown, Arneth, Finnigan, & Rounsevell, 2019; FAO, 2019). However, there are critical gaps in the literature that need to be addressed for sustainable development. For instance, there is inadequate attention to certain issues, such as food sovereignty and food waste; insufficient exploration of the intersections between food security and other global issues such as gender inequality and environmental sustainability;
