What the texts say
Charaka calls this paka viruddha, incompatibility in cooking. Burnt food sits in the same line as undercooked rice, overcooked food and food cooked over poor fuel. The verse names these faults and gives no reason or specific harm for any of them.[1]
The modern view
We found no study that tests Charaka's rule as he gives it. What forms in food when it burns is a separate question for modern food-safety research, and we have not reviewed that work for this card.
