Source of Energy

Cereals are probably the greatest source of energy for humans. Providing almost 30% of total calories in a regular diet, cereals are probably the most widely consumed caloric food in America. This percentage rises in places like rural Africa, Asia and India where cereals are reported to supply almost 70 to 80% of energy requirements (since people in these regions cannot afford to eat other food products like fruits, vegetables, meat, or milk products. Cereals are inexpensive and a widely available source of energy; this is probably the prime reason why people from all budgets prefer cereals as the major energy provider in their diet. Cereal intake tends to be quite high amongst poor income families as they attain a good amount of energy through minimal expenditure.
