How essential is hot food
Temperatures have dropped below zero in the UK so we wrap up to keep warm when we go out.
Our bodies generate heat and this keeps us warm, providing the clothing has good insulating properties eg down-filled duvet jackets and trousers etc. We re-fuel our bodies with food and water which continue to generate heat. As a result we can survive for long periods of time (weeks? months? Years?) in an outdoor environment without fire or hot food.
Normally, we refuel our bodies with hot food and hot drinks, especially when the temperature is low. So far as I know, we are the only animals around today who heat our food and water, although Neanderthals probably heated their food and drink in the past.
Did our modern human ancestors always heat their food and water or is this a recent invention?
How long could we survive without hot food or hot water?
Cheers
Don
