Record and analyze your favorite fast food using Iprofile® within
WileyPLUS®.
Select one of the following:
Option 1
Watch the video on WileyPlus®: How to use iProfile® within Ch. 1.
Create your profile and enter your favorite fast food menu. If you do
not consume fast food yourself, enter a friend’s (or relative’s) profile
and his/ her favorite fast food menu.

After completing the option you chose, answer the following in at
least 175 words:
• Explain how individuals can make healthier choices if they choose
to eat at fast food outlets. Where are the “hidden calories” in typical
fast food menus? What options exist at fast food restaurants for
making healthier choices? Do you think it is possible to have a well-
balanced diet made up of primarily fast food and why do you feel this
way or not? What tools are available for consumers today to learn

Intake 1 Day

Resources: Ch. 2 of Visualizing Nutrition, WileyPLUS®, iProfile
Enter your food intake for 1 full day by following the
WileyPLUS® iProfile instructions.
Write a 750- to 1,050-word paper that addresses the following points
about your 1-day food intake:
 Review your iProfile Journal, the dietary reference intake (DRI),
and the iProfile Intake Spreadsheet. Does your dietary intake for
the day you recorded provide a healthful diet? Why or why not?
 Did you consume the recommended DRI from each of the food
groups, vitamins, and minerals?
 Which groups of foods are underrepresented or overrepresented
in your diet? If you did not consume the recommended number
of servings from each group, explain why. Propose how you
might consume the recommended number of servings from each
group in the future.
 Did your diet provide an adequate variety of foods, or were your
choices limited? Refer to the Food Pyramid in iProfile to see
how you fulfilled your goals for the various food pyramid
groups. If you did not eat a variety of foods, how might you
expand your field of choices?
 Compare your diet to that of the sample profile for Kelly
Watson. Whose diet provides the best opportunity for health and
well-being? Which profile provides the best philosophy of
health? Provide a rationale for your answers.
Note: Please see the instructions in iProfile found within the
heading/link “Sampe Profile” for the gathering of Kelly Watson’s
profile information. After it has been saved and downloaded, it will
arrive as a zip file. Be sure to “unzip/extract” the profile information
for Kelly Watson before importing the data into iProfile. If the

information is not “unzipped/extracted”, an error message will be
