Monosaccharides are single sugars → fructose, glucose, galactose
Disaccharides are pairs of monosaccharides, one of which is always glucose → maltose (glucose + glucose), sucrose (glucose + fructose), lactose (glucose + galactose)
Polysaccharides → few (oligosaccharides) or many (polysaccharides) glucose units bound/linked together in straight or branched chains, storage form of glucose in the body, provides a rapid release of energy when needed → glycogen, starch, fibre

The Glycemic Index (GI) of a food is a number assigned to it between 1 and 100, similar to a percent rating
The GI of a food tells us how easily our body is able to digest components of the food
we are able to make healthier choices and substitute common items in our diet
Low GI < 55
Medium GI 56-69
High > 70
important for carbohydrates as Protein and fat have minimal influence over GI
