In Ayurveda, Ahara refers to all substances consumed through the mouth for the nourishment and maintenance of the body. It is regarded as one of the three principal supports of life and the primary source of strength, complexion, vitality, intellect, growth, health, and longevity. The effect of food depends on its quality, quantity, preparation, compatibility, time of intake, season, digestive capacity (Agni), and the individual’s Prakriti. Properly selected and digested Ahara maintains the equilibrium of Dosha, nourishes the Dhatu, promotes Ojas, and prevents disease, whereas improper dietary practices may disturb digestion and produce illness.
