FOOD AND US
Introduction
Food is any substance consumed to provide nutritional support for our 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.
Food and the nutrients obtained from food are vital to keep the body healthy and alive. Nutrients are required in order to build and repair cells and body tissues, maintain the organs and bones in optimum working condition and to provide energy, fuel and warmth.
Good nutrition is essential for good health and eating nutritious food can help to prevent against common ailments, as well as more life threatening illnesses and diseases.

Food sources
All food has its origin in plants. Some food is obtained directly from plants; but even animals that are used as food sources are raised by feeding them food derived from plants. Cereal grain is a staple food that provides more food energy worldwide than any other type of crop. Maize, wheat, and rice - in all of their varieties - account for 87% of all grain production worldwide. Most of the grain that is produced worldwide is fed to livestock.
Other foods not from animal or plant sources include various edible fungi, especially mushrooms. Fungi and ambient bacteria are used in the preparation of fermented and pickled foods like leavened bread, alcoholic drinks, cheese, pickles, kombucha, and yogurt. Another example is blue-green algae such as Spirulina.[3] Inorganic substances such as baking soda and cream of tartar are also used to chemically alter an ingredient.
