Rasa, Guna, and Virya: The Science of Ayurvedic Nutrition Ayurveda doesn’t just look at calories or nutrients; it classifies food based on Rasa (taste), Guna (qualities), and Virya (potency). - There are six Rasas: sweet, sour, salty, pungent, bitter, and astringent. Each impacts the Doshas differently. - Guna refers to qualities like hot/cold, heavy/light, dry/oily, etc., which influence how food behaves in the body. - Virya determines the food's heating or cooling effect. This system helps determine which foods are suitable for each Dosha and season, offering a more intuitive and holistic approach to nutrition.
