The earth faces serious challenges including climate change, global warming, biodiversity loss, water scarcity, pollution, resource depletion, nuclear threats, and geopolitical tensions which are due to human activity. Innovations in biotechnology have been able to mitigate of these problems. Functional foods are a vital extension of functional agriculture, as they provide exact nutrition as well as nutritional and therapeutic benefits. Functional meals offer the best solution to the global concerns of malnutrition and hidden hunger. Environmental and ethical considerations are significant factors when it comes to production of functional foods. These can be achieved by minimizing carbon footprint and water use, sustainable practices, circular economy approaches and following ethical guidelines in animal-based functional food production. Social sustainability and food security can be achieved by making functional foods better tools for public health, making it accessible to low-income communities and marketing with ethical pricing. Regulations, certifications and following ethical frameworks are absolutely necessary to ensure ethical production and distribution of functional foods. Case studies such as Amul India have shown the success of functional food production. Balancing productivity and sustainability remain a core challenge. Innovation, consumer rights and cultural factors remain as a challenge too. So, roadmap of 5 goals should be followed.
