Abstract:

Ayurveda emphasizes health as a dynamic equilibrium of Dosha, Dhatu, Mala, and Agni rather than merely the absence of disease. The present conceptual study explores the role of Ahara Parinamkara Bhava—the physiological factors responsible for the transformation and assimilation of food—in maintaining optimal health. According to Acharya Charaka, digestion and metabolism are governed by six key factors: Ushma (heat/digestive fire), Vayu (motility), Kleda (moisture), Sneha (unctuousness), Kala (time), and Samyoga (proper coordination). These factors collectively ensure the proper breakdown, digestion, absorption, and tissue nourishment from ingested food.

The study highlights that balanced functioning of these factors leads to the formation of pure Ahara Rasa, which subsequently nourishes all Dhatus and supports the formation of Ojas, thereby sustaining immunity and vitality. Disturbance in any of these components may lead to incomplete digestion and the formation of Ama, which is considered a root cause of multiple systemic disorders. The paper also correlates classical Ayurvedic concepts with modern physiological processes such as enzymatic digestion, peristalsis, secretion of digestive fluids, and time-dependent metabolic activity.

Overall, the study emphasises that health depends not only on diet quality but also on the body's functional capacity to transform and assimilate food efficiently through coordinated physiological mechanisms described as Ahara Parinamkara Bhava.
