world's largest crops, and are therefore staple foods. They include
rice, wheat, rye, oats, barley, millet, and maize (Corn).Cereals provide
food eaten directly as whole grains, usually cooked, or they are ground
to flour and made into bread, porridge, and other products.
There are many types of cereals , that come in different shapes, colours
and flavours.
