Malnutrition is a worldwide health problem, especially in countries with low or intermediate incomes. Even after decades of progress, there are still differences between institutions, limited access to nutrient-dense meals, and food instability. Functional foods, which offer more than just nutrition, could be a long-term answer to problems with macronutrients and micronutrients. The capacity of functional foods to address malnutrition is analyzed through peer-reviewed scientific research, global health statistics, and policy frameworks. The study examines agricultural innovation, public health nutrition, and food science perspectives to identify optimal intervention and delivery approaches. The review says that functional meals that include biofortified staple crops, fermented probiotics, and plant foods high in phytochemicals can help with nutrition, immunological function, and the risk of non-communicable diseases. Case studies demonstrate that effective collaboration among sectors encompasses policy-driven food systems, public-private partnerships, and community-oriented distribution. Incorporating functional elements into normal diets and national dietary recommendations helps minimize malnutrition. They should be included in future global health and food security programs because they offer culturally appropriate, nutritionally superior, and affordable food. To observe their impact, we need long-term investments, involvement from all stakeholders, and policies that are in line with each other.
