A food is any substance utilized by a living thing for energy (or for growth and repair).

There are both plant and animal sources for foods. One can eat grains in the
form of bread, and one can eat the meat of an animal that ate such grains.

Other nutrients required by the human body include water, minerals and vitamins.

Vitamins are a group of chemicals that are required in very small quantities for the proper functioning of the body.

Vitamins are found in varying amounts in different foods.

In fact, many processed foods contain artificial vitamin supplements.
