Can we reheat cooked food?
We do not recommend reheating food that has been cooked.
Cooking food in the first place reduces its life energy. Reheating will destroy that energy and the food will no more be nutritious to eat. It will become dead in nature. When you eat something that is dead, it will bring death to your own body.
Always eat your cooked meals within 3-4 hours of preparation.
Lord Krishna in Bhagwad Gita, Chapter 17, Verse 10 talks about why we should eat food within three hours of its preparation.
"yata-yamam gata-rasam puti paryusitam ca yatucchistam api camedhyam bhojanam tamasa-priyam"
Food cooked more than three hours before being eaten, which is tasteless, stale,
Putrid, decomposed, and unclean, is food liked by people in the mode of ignorance.
