However, traditional sources face limitations amid increasing global food security and sustainability challenges. This study aims to evaluate the nutritional potential of novel foods, including microalgae (e.g., spirulina and chlorella), fungi (e.g., oyster and shiitake mushrooms), edible insects (e.g., mealworms and migratory locusts), and unconventional plants (e.g., water lentils and canihua). The study will compare their amino acid and fatty acid profiles with those of conventional animal and plant sources. The comparative analysis conducted in this study reveals that these innovative foods offer balanced and high-quality protein and lipid profiles, and contribute essential nutrients needed to prevent deficiencies and support metabolic health. Significantly, the integration of these novel foods into established dietary patterns, such as the Mediterranean diet, has the potential to enhance nutritional quality while promoting environmental sustainability. In conclusion, the adoption of these innovative food sources provides a viable strategy to meet nutritional demands and address global health and ecological challenges, paving the way toward a more resilient and sustainable food system.
