Food is a substances consumed by a living organism by way of eating or drinking in order to maintain life and growth. Animals gain energy and nutrition from food. Any product intended to be eaten or drunk or used as an ingredient in the process of producing such products is typically considered to be a type of food.
Most food originates from plants and animals. Vegetables, fruit, grasses, legumes and nuts are examples of vegetation-based products, while dairy products, meat, poultry, eggs and seafood are examples of animal-based products. Mushrooms, water and salt are examples of foods that come from neither plants or animals.
