Cereal

Cereal usually refers to a type of grass that is grown to be eaten. Some, such as wheat, are mostly used to feed people. Some are fed to cattle, and lesser amounts are used for other purposes. 
It is a common breakfast meal. The kind of cereal eaten for breakfast is called breakfast cereal. This is made of grain, and usually eaten with milk in the United States. It is often sweetened with sugar, syrup, or fruit.
The word "cereal" comes from 'Ceres', the name of the Roman goddess of harvest and agriculture. Grains are called "corn" in the United Kingdom and Ireland, but in the United States, Canada, Australia, and New Zealand "corn" means "maize".
History.
In the 19th century, Americans ate meat a lot for breakfast and usually did not eat grains and fiber. But after that, people who were interested in eating more healthy foods began a push for healthy breakfasts.
This brought up the creation of Granula. The name "Granula" comes from "granulates", formed of grain. In 1863 this became the first breakfast cereal and included heavy nuggets made from bran, the outer husk of a grain that is taken out when making flour. The cereal had to be soaked overnight before being eaten. Simply pouring milk over it was not enough to make it eatable.
The cereals eaten today grew out of a health campaign that began in the 1860s. Thin baked dough served to patients in hospitals inspired two men, C.W. Post and W. K. Kellogg. These two men started their own companies, named them after themselves.
