In Ayurveda, food is believed to influence both the mind and body. By understanding how to make foods that align with our unique constitutions, we can use nutrition as a powerful tool for healing. Traditional knowledge and modern science are coming together to show how food can be used as medicine. In Ayurveda, the concept of Pathya Kalpana highlights how food can be prepared in a way that supports healing and health. This idea is very similar to the modern concept of nutraceuticals, where certain foods or food-based products are used to prevent or manage diseases. Nutraceuticals is a word made by combining "nutrition" and "pharmaceuticals". These are food-based products that have proven benefits in managing long-term (chronic) diseases. This idea is quite similar to the Ayurvedic concept of Pathya Kalpana’s ideas of Hita, Ahita, Satmya, Asatmya, and Pathya-Apathya are similar to how nutraceuticals are chosen and used. The Ayurvedic concept of Rasayana refers to certain foods that can be taken daily to maintain good health, boost vitality, and promote rejuvenation—this also matches the goal of nutraceuticals. This article explores the philosophical, functional, and therapeutic correlations between Nutraceuticals, Rasayana and Pathya Kalpana, highlighting the potential for Ayurvedic dietary formulations to inform the future of functional nutrition and integrative healthcare.
