In poorer countries, these easily digested and relatively inexpensive nutrients often provide well over 80 percent of every day's calories.

Chemically, carbohydrates are naturally occurring compounds composed of carbon, hydrogen and oxygen (CHO). In many cases the hydrogen-to-oxygen ratio of carbohydrates is the same 2 to 1 ratio as that of water. (Originally, chemists believed that all members of the class could be described as "carbon hydrates," which is how the name originated.
