Unit I Homework
Nutritional Analysis
Introduction
In Chapters 3 and 4 of the textbook, you learned that the body needs various macro and micronutrients in
order to function properly. You also learned about cellular metabolism and what the human body uses as
a fuel source. This all seems simple at first glance; however, it can be difficult to determine whether we
are getting what our body needs. Even when we know what our body needs, it becomes even more
difficult to make sure we are supplying our body with those needs. The car you drive probably requires
gasoline in order to function properly. When you need to go somewhere, you make sure you have enough
gasoline in the tank to reach your destination. If you do not, you probably stop at a gas station and fill
your car’s tank with gas. You do not pour cola in the tank or jelly donuts; you put gas because that is what
it needs. Why do we put cola and jelly donuts in our bodies when we do not need them? Often, it is
difficult to determine what is in the foods that we eat. Sometimes it is hard to determine if the food
contains the correct nutrients or processed foods that our body does not need. This lab exercise will help
you learn how to read nutritional labels and determine what your body needs to function properly.
Objectives
1. Analyze nutritional information based on what the body needs to function properly.
2. Calculate BMI and learn about caloric balance.
Materials
