People all across the world are grappling with increased rates of chronic diseases and nutrient shortages while also maintaining limited natural resources, making sustainable nutrition a topic of global importance. Sustainable nutrition entails making healthy, nutrient-dense foods available, affordable, and culturally appropriate while simultaneously conserving natural resources and supporting local communities. “Nutritional sustainability is defined as a food system's ability to deliver sufficient energy and necessary nutrients to maintain population health without jeopardizing future generations' ability to meet their nutritional needs.” It's worth noting that nutritional sustainability breakthroughs are frequently linked to product development in the pet food sector, which is more likely to utilize alternative biomass sources and by-products from the “human food chain.” The need to change to more sustainable diets and food systems is becoming more apparent, but it is far from straightforward. Dietary sustainability, according to the FAO, includes economic and socio-cultural factors in addition to nutrition and the environment.
