Carbohydrates: Fael and Fibre 23<br />
Complex carbohydrate no. 2: Glycogen<br />
Glycogen is the second type of complex carbohydrate. It is<br />
how the human body stores glucose. Sometimes called<br />
'animal starch', glycogen does not occur in plants. We store<br />
most of it in the liver (up to 400 grams) as well as in the<br />
muscles (up to 100 grams). Glycogen is stored as ready<br />
energy. Like going to the store for food, if insufficient glucose<br />
is available from the bloodstream, it can be obtained by<br />
breaking down stored glycogen.<br />
Complex carbohydrate no. 3: Ffbre<br />
The third type of complex carbohydrate is fibre (also see<br />
fibre, page 29). At first glance under the microscope, fibre<br />
looks very similar to starch - a large group of glucose molecules.<br />
Upon closer examination the dissimilarity becomes<br />
apparent: the bonds holding the glucoses together in starch<br />
are different from the bonds holding the glucoses together in<br />
fibre. Humans don't possess the specific enzymes to untie<br />
these bonds, so the fibre continues down the digestive tract<br />
undigested. Cows and other animals have these enzymes in<br />
their rumen which explains why a horse can enjoy a square<br />
meal of hay and we can't.<br />
Glycaemtc index<br />
The glycaernic index is a ranking of foods based on their<br />
immediate effect on blood sugar levels. The greater the<br />
index, the quicker and higher blood sugar levels rise.<br />
Glucose is the gold standard at 100. Blood sugar levels<br />
are important for many things, including brain function,<br />
energy levels, insulin production and mood.<br />
Not all sugars are created equal. Glucose readily<br />
crosses over the intestinal wall into the bloodstream.<br />
The other single sugars vary in the speed at which they
