The Truth About Sugar

What is sugar or sugars?

“Sugars” are a group of carbohydrates that sweeten our food. 

  • They have different names such as “glucose,” “fructose” and “lactose.”
  • The sugar we usually talk about is white or brown table sugar, which is “sucrose.”

Are some types of sugar better than others?

All sugars, whether they occur naturally or are added to a food, have the same nutritional value and are used by your body in the same way.  All sugars provide 16 calories per teaspoon (4 calories per gram).  
Choose foods that have naturally occurring sugar, such as what is in fruits, vegetables and milk, over foods with lots of added sugars – what food manufacturers add to foods to provide sweetness and flavour and to increase the item’s shelf life.

Did you know that:

  • Brown sugar is not more nutritious than white. Brown sugar is usually white sugar with molasses added to the sugar crystals.
  • Honey is not better for you than white sugar. All sugar provides energy but no significant amounts of other nutrients. 
  • All sugars are “empty calories”, meaning they provide no significant amounts of nutrients. 
See the table below for sugar amounts found in some common foods.

Is excess consumption of sugars related to disease?

Excess consumption of sugars poses several health risks. Sugars are a carbohydrate and increase blood sugars quickly. Eating foods high in sugar will not cause diabetes.

Type 2 diabetes may be prevented with good nutrition habits and regular physical activity.   Ensure a healthy diet by consuming lean meats and alternatives, low-fat milk and alternatives, and foods that are rich in fibre.  Type 1 diabetes cannot be prevented.
