Food is any substance consumed to provide nutritional support for the body. It is usually of plant or animal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism and assimilated by the organism's cells in an effort to produce energy, maintain life, or stimulate growth.
Historically, people secured food through two methods: hunting and gathering, and agriculture. Today, most of the food energy consumed by the world population is supplied by the food industry.
Raw foodism (or rawism) is a diet consisting of uncooked, unprocessed, and often organic foods or wild foods.
Depending on the type of lifestyle and results desired, raw food diets may include a selection of raw fruits, vegetables, nuts, seeds (including sprouted whole grains such as gaba rice), eggs, fish (such as sashimi), meat (such as carpaccio), and non-pasteurized/non-homogenized dairy products (such as raw milk, raw milk cheese, and raw milk yogurt).
