Freshness, Leftovers and Storage
The Ayurvedic Kitchen
About 1 min read
Ayurveda regards food cooked more than about three hours earlier (paryushita) as having lost its vitality, and reheated, stale food as tamasic. Modern food safety agrees for different reasons: bacteria multiply quickly between 5 °C and 60 °C. For older guests, whose immunity is lower, both sets of reasoning point the same way.
