26. The Eight Factors of Wholesome Eating

Charaka (Vimanasthana 1) names eight factors that decide whether a meal nourishes or harms — the ashta ahara vidhi visheshayatana. They are a complete checklist for any kitchen, and they show that the same food can be medicine or poison depending on how it is prepared, combined, measured and eaten.
