Now we're ready for 2. Glycogen.
Watch the Video Clip below to begin this part.

Video Clip: Glycogen approximately 4 minutes Glycogen video |
The Video Clip says that glycogen is important to
provide fuel when you don't eat. Could you add
to your notes that glycogen is important
to provide fuel as
glucose (for the brain & nervous system) when
you don't eat The body can make glycogen from eating foods rich in starch and sugar. Starch and sugar are broken down into monosaccharides, and ultimately become glucose which can then be stored as glycogen. As mentioned before, WHOLE foods are the best ones to eat to get this sugar and starch because they also provide fiber, vitamins, minerals and phytochemicals. Read through the remainder of the Glycogen part in your lecture outline. An important point is that although glycogen is in BOTH the muscles & the liver, the glycogen in only ONE of those places can get into the blood and travel. Therefore only one of those places can provide glucose to the brain. From looking at the Video Clip above, you should be able to describe how glycogen is different than starch in structure. |

And now we're ready for 3. Fiber. Types- Soluble & Insoluble Before watching the Fiber Video Clip below, here's the main purpose of cellulose in plants- to provide supporting structure for the plant. |
Video Clip: Fiber approximately 10 minutes Fiber video |
Questions about fiber the video did not
answer:
Why it's good
for us to eat foods with insoluble fiber? You
can think of Insoluble fibers as
being good for Intestinal
health. As the text book mentions, insoluble
fibers increase fecal weight and speed fecal passage
through the colon. Therefore insoluble fibers
can alleviate constipation, among other
things. Also insoluble fibers provide bulk and
a feeling of fullness which may help with weight
management. As always, the best way to get fibers is going to be from whole foods where they come packaged with other vitamins, minerals, and phytochemicals. For example fruits, vegetables, beans, and whole grains like oats, barley, rice and wheat. |
This is a 1984
label. Below is a
bigger version of this label. |

they DID NOT mention the fiber content. |
Above is a 10-grain hot cereal from Bob's Red Mill, a Portland company. Notice its high fiber content (5g). |
One pear (above) has the same amount of dietary fiber as the serving of the 10-grain hot cereal (5g). |
These saltines are made from wheat flour, but it's not WHOLE wheat. Notice the fiber content (0g). |
