Digestion Case Study

Part I:

This case study is about carbohydrates, how they are made and the effects they have. We were able to identify and come up with a rule to help us know which foods contained carbohydrates. We learned that anything containing sugar also contains carbohydrates. Carbohydrates are made during the process of photosynthesis which produces glucose. Lastly, we learned that carbon and oxygen cause gas.

In the PowerBar, 31% of the carbohydrates were simple sugar.

The girls would not be able to omit all carbohydrates that are not well digested because they are found in almost all foods. Healthy foods such as fruits and vegetables also contain carbohydrates.

Even though they are all carbohydrates, simple sugar, starches and fibers are all different from each other. Simple sugars are one or two sugar units long and have a sweet taste such as milk, fruit and honey. Complex carbohydrates like starches can be thousands of sugar units long. Example of starches are potatoes, pasta and corn. Lastly, fiber a complex carbohydrate that is non-digestible. Examples of fiber include bran, dried beans and brown rice.

In the PowerBar, the ingredients that would be categorized as simple sugars are the salt and glycerin. The complex carbohydrates like starches are the high fructose corn syrup with grape and pear juice concentrate, rice crisps (milled rice, rice bran), peanut, and brown rice. The complex carbohydrates that contain fiber are the oat bran and maltodextrin. The carbohydrate that would produce gas according to the list is the milk protein isolate.
