Food Source

Most 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. Pulse grain is a type of 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.

Some foods not from animal or plant sources include various edible fungi, especially mushrooms. Fungi and ambient bacteria are used in the preparation of fermented foods like  alcoholic drinks, cheese, pickles, and yogurt. Another example is blue-green -algae such as spirulina. Inorganic substances such as salt, baking  soda are used to preserve or chemically alter an ingredient.
