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.

Determine your BMI
The point of this exercise is for the student to become familiar with his or her own score using a very common biometric indicator. Conduct the exercise using your own data. However, if you do not wish to disclose your own data, then conduct it again with reasonable fictitious data and report that.
Questions 1-4 below are short answer questions. Answer each question in the space provided.
1. What is your height? ft in What is your weight? Lbs
Go to: https://www.choosemyplate.gov/ then click on ONLINE TOOLS in the menu and select BMI CALCULATOR from the drop down menu. Follow the links to the calculator tool hosted by the CDC.gov website. Enter the information to determine your BMI (or use the fictitious data) by clicking the link to the Adult BMI Calculator.
Type the information from above into the appropriate spaces and then click: Calculate BMI.
2. What is your BMI? What recommendations are listed?
On the left menu click on: Finding a Balance.
3. What is the caloric balance equation?
4. Do you think you are in caloric balance? What are the recommended physical activity levels?
Determine your daily caloric input. Prior to completing this part of the lab, you will need to write down everything that you eat and drink for an entire day. Make sure you record everything, and divide the foods into breakfast, lunch, dinner, and snacks. If you do not write down everything, you will have to try to think back and remember what you have eaten for entire day; make sure you include the full 24 hours. Try to pick a typical day. If you are going to a party or have to fast for a lab test, pick a different day.
• Go to the U.S. Department of Agriculture health food and fitness page: https://www.supertracker.usda.gov/ or copy and paste this address into your web browser.
• Click on: FOOD TRACKER
• Start with breakfast, and type in each food that you ate for one day. After each food you type in, click GO.
• Select the closest food from the list that is generated.
• Determine the amount and click the box for the meal in which the item was consumed.
• Click ADD.
• Continue this process until you have included all foods that you ate in a 24-hour period.
• Click on MY REPORTS in the menu at the top of the page.
• Click on FOOD GROUPS & CALORIES.
• Enter the Date and click on CREATE REPORT.
Answer the following short answer questions:
1. How many total calories did you consume?
2. What are empty calories?
3. How many empty calories did you consume?
Next, you will create a Nutrition Report.
• Click on MY REPORTS, and generate a NUTRIENTS REPORT.
• Export this report as a Word document by clicking on WORD just above the CREATE REPORTS button in the top right corner of the page.
• Open the Nutrient Report that you saved, and copy and paste it after the following question. Paste it in the area marked "Copy and paste your Nutrients Report here."
Answer Question 4 in essay format. Your answer should be at least 100 words in length.
4. Using the information in the report and the information that you calculated concerning your BMI, what did you learn about your eating habits? Is there anything that you would change? Are you deficient in any nutrients? Are you above the required amounts in any nutrients?
