THE CHEMICAL CHANGES OF 
FOOD 
CARBOHYDRATES
CARBOHYDRATES 
 Carbohydrates are any one of various substances 
found in certain foods (such as bread, rice, and 
potatoes) that provide your body with heat and 
energy and are made of carbon, hydrogen, and 
oxygen 
 Carbohydrates are divided into two types, simple 
and complex. The classification is based on the 
chemical structure and reflects how quickly sugar 
is digested and absorbed.
Simple Carbohydrates 
 Simple carbohydrates are also called simple 
sugars and are chemically made of one or two 
sugars. A simple sugar can be just what the name 
implies, the sugar in your sugar bowl. Things like 
candy, syrups, and soda pop are also 
straightforward examples of simple carbohydrates 
 Simple carbohydrates also include foods such as 
fruit and milk. These are better sources of simple 
carbs because they contain vitamins and fiber, 
and also important nutrients that your body 
needs, like calcium.

MILK
FRUITS
COMPLEX CARBOHYDRATES 
 Complex carbohydrates are also known as 
starches and are made of three or more linked 
sugars. Grains such as bread, pasta, oatmeal 
and rice are complex carbs, as well as some 
vegetables like broccoli, corn legumes such as 
kidney beans and chick peas. They take the 
longest to digest.
