Summary
Carbohydrates are the perferred source of energy for the human body.
Monosaccharides, disaccharides and polysaccharides make up the main sources
of dietary carbohydrates. Monosaccharides are single sugars that consist of
glucose, galactose and fructose. Glucose is the sugar that is found in the blood.
Dissaccharides are double sugars that are made from monosaccharides. They
include, sucrose, lactose and maltose. The digestive system will break them down
to their single sugar units before they are absorbed into the blood. Polysaccharides
are strings of monosaccharides. They make up starch, fiber and glycogen.
These carbohydrates are often referred to as “complex carbs”. This category
of carbohydrates also contains our whole grains which are an important part of
nutrition. Food scientist ask us to identify and limit simple sugars in our diet while
eating at least 3 servings of whole grains every day.
