Testing For Simple Sugars
Aim
I want to find out how to test for simple sugars.
Simple sugars are carbohydrates that are quickly absorbed by the body to produce energy. They are also classified
as “simple” because they contain only one or two units of sugar or saccharides.
Also referred to as simple carbohydrates, these sugars are found naturally in a variety of
foods that we consume daily.

Extra for experts
Two different types of sugar exist: simple and complex. Complex sugar takes longer for your body to break down and is healthier for your body. This type is found in natural carbohydrates such as whole grains and fruit. On the other hand, simple sugar is broken down by your body quickly and causes energy ups and downs. This type of sugar includes refined and processed sugar found in table sugar and added to many sweets. Consuming an excess of simple sugar comes with numerous health problems
- Give two examples of simple sugars and complex sugars in your daily food.
- At what times of the day may you need simple sugars?
- Do you think that it would be wise to eat simple sugars before bed? Why/why not?
