Food is any substance that is consumed by living organisms in order to provide energy, nutrients, and other essential substances necessary for growth, maintenance, and repair of the body. In human beings, food is typically ingested through the mouth, where it is broken down by enzymes and digestive juices, absorbed into the bloodstream, and transported to the various organs and tissues of the body.
Foods can come from a variety of sources, including plants, animals, and fungi. They can be prepared in a wide range of ways, including cooking, baking, grilling, and fermenting, and can be eaten raw or cooked. The nutrients found in food include carbohydrates, proteins, fats, vitamins, minerals, and water, and a healthy diet typically includes a balanced mix of all of these nutrients.
