ABSTRACT
Nowadays, the world has been characterized by hunger, obesity, and food loss and waste (FLW). With the COVID-19 pandemic, the food issue became more intense, serious, and evident. Hunger demands urgent actions. Obesity levels have been raised and are removing health and quality of life from the population. Production planting practices and the food supply chain are not necessarily ecologically friendly. Sustainability issues greatly intensify social problems. As well as food loss (FL), food waste (FW), and sustainability concerns, obesity, and malnutrition are enhanced due to the lack of knowledge by the population. Processed food (PF), packaging, and additives, despite still needing improvement, are essential to food security control. Nowadays, hunger is not due to insufficient agricultural practices but rather to inequality and absence of adequate public policies. In the context of a certain abundance of food production and processing, the hunger scenario in contrast to FLW is an ethical, social, moral, and sustainable issue. In this context, a Food-Based Dietary Guideline (FBDG) can be an important public policy tool from the health, nutrition, environmental, and educational points of view. Despite the effort, the literature shows that FBDGs can be better used to fulfill healthiness and sustainability purposes. In this scenario, the elaboration/revision of the FBDG, adopting a clearer, simpler, and a better-suited communication strategy is essential. In this way, this article discusses the importance of the FBDG as a public policy tool, not only regarding health issues but also communication strategies, production sustainability, and humanitarian ones, which are crucial to FBDG's efficiency.
