What is the purpose of cooking food?

Cooking is the act of preparing food for eating by the application of heat. Applying heat to a food usually, though not always, chemically transforms it, thus changing its flavor, texture, appearance, and nutritional properties. The diversity of cooking worldwide is a reflection of the myriad nutritional, aesthetic, agricultural, economic, cultural and religious considerations that impact upon it. The effect will depend on temperature, cooking time, and technique used. The temperature range from 5°C to 57°C (41°F to 135°F) is the "food danger zone." It may kill or inactivate potentially harmful organisms including bacteria and viruses. Cooking is the act of preparing food for eating by the application of heat.
