Know
Your Sugars
Sugars are one of the most
misunderstood parts of our daily food supply. Many people believe that eating sugars can
lead to certain forms of sicknesses, however, research has failed to link sugars to the
development or cause of any chronic disease. Even though cavities may be associated with
eating sugar, cavities can also result from eating other carbohydrates including starches.
Sugars are common food ingredients that
are found in many forms. Since sugars are carbohydrates, they are a contributor of
calories for the body - an important energy source.
There are no nutritional differences
among sugars. The body uses all types of sugars in the same way. During digestion, sugars
are broken down and enter into the bloodstream. They travel through the blood stream to
body cells, where they provide energy and help form proteins.
As carbohydrates, sugars are preferred
as a fuel during high-intensity activity (1, 2).
Sugar does not cause hyperactivity, nor
does it negatively affect mental performance (3). Further, no particular group of children
reacts to sugars differently from the general population. Actually, research suggests that
sugars tend to calm both children and adults (4). This could just go unnoticed due to
other influences, such as a birthday party in which everyone is excited to begin with.
Brief
History of Sugar 
500 years ago, sugar was a rare spice
or medicine, imported to Europe from India. Then it became an expensive commodity
primarily produced in overseas tropical colonies. It later grew into a less-costly
commodity produced and traded among countries, and finally became a cheap everyday
commodity, produced from both sugarcane and sugar beets. By about 1970, approximately 9%
of all available food calories in the world, were in the form of sucrose. No other food in
world history has had a comparable performance.
Sugars
| Glucose |
(Dextrose, Grape Sugar, or Corn
Sugar). Somewhat less sweet than cane sugar and is soluble in hot or cold water. It is
found in sweet fruits such as grapes, berries, and oranges and in some vegetables such as
sweet corn and carrots. It is prepared commercially as corn syrup. |

|
|
|
|
| Fructose |
(Fruit Sugar). Highly soluble. It
is much sweeter than cane sugar and is found in honey, ripe fruits, and some vegetables. |

|
|
|
|
| Sucrose |
The table sugar with which we are
familiar and is found in cane or beet sugar, brown sugar, molasses, and maple sugar. Many
fruits and some vegetables contain small amounts of sucrose. |

|
|
|
|
| Lactose |
(Milk Sugar). Produced by mammals
and is the only carbohydrate of animal origin of significance in the diet. It is about one
sixth as sweet as sucrose and dissolves poorly in cold water. The concentration of lactose
in milk varies from 2 to 8 per cent, depending upon the species of animal. |

|
|
|
|
| Maltose |
(Malt Sugar). Does not occur to
any appreciable extent in foods. Maltose is produced in the malting and fermentation of
grains and is present in beer and malted breakfast cereals, it is also used as a source of
carbohydrates for some infant formulas. |
