Introduction
You are what you eat! So are you ice cream or
broccoli? You're on a mission to find out! Along the way, you'll collect
and analyze data about what you eat over a period of five days. You'll
take into account serving sizes, Calories, and fat grams. You'll also
take on the roll of a nutritionist, researching the Food Pyramid and
creating a healthy meal plan. So bring a hearty appetite and your math
tool kit. This adventure will tantalize your taste buds!
The Task
Below is a brief description of each activity
you will complete as a nutritionist. The Process
section has a detailed description of each activity, and the Resources
section has some helpful Web sites that you are urged to use. So get
ready to digest a plateful of mathematics! Nutritional
Challenge 1:
First, keep a record of all the food that you eat for five straight
days, keeping a record of the amount you eat as well as the different
characteristics of the foods.
Nutritional Challenge 2:
Second, research the Food Pyramid and create the healthiest meal from
a selection of food choices.
Nutritional Challenge 3:
Third, create a presentation that includes your nutritional analysis
of what you currently eat and of what you feel is a wellbalanced meal.
The Process
Below is a detailed description of each nutritional
challenge.
Nutritional Challenge 1:
 Create a chart and record everything that you eat for five consecutive
days. Your chart should include the following information for each
item consumed:
 the name of the food,
 the number of servings consumed,
 the number of Calories per serving,
 the total number of Calories consumed,
 the amount of fat per serving, and
 the total amount of fat consumed.
Do not round your numbers. Use decimals where necessary.
 Create a second chart that contains the same information as the
first. For this chart, convert all of your data from decimal to fraction
form. Do not, however, write whole numbers as fractions.
 Now that you have charted your food intake, it is time to analyze
your diet. Printout and answer the questions found on the food analysis
worksheet.
Food Analysis Worksheet
NAME:_______________________________
DATE:_________________
Below are your analysis questions. Print
this page out, and be sure to show all of your work in the provided
space.
 What was your mean Calorie intake for the five days charted? Write
your answer as a fraction in simplest form.
 What was your mean fat intake in grams for the five days charted?
Write your answer as a decimal.
 What was the median and mode for your Calorie intake for the five
days charted? Write your answer as a decimal.
 What was the median and mode for your fat intake in grams for the
five days charted? Write your answer as a fraction in simplest form.
 Find the mean of your total breakfast Calorie intake. Write your
answer as a decimal.
 Find the median of your total fat intake in grams for your lunches.
Write your answer as a fraction in simplest form.
 Find the mean of your total dinner Calorie intake. Write your answer
as a decimal.
 Find the mean number of servings of food you ate per day.
 Looking at your charted food, what category of food did you consume
the most of? Find the mean number of servings from that category you
consumed.
 What category of food did you consume the least of? Find the mean
number of servings from that category you consumed.
Nutritional Challenge 2:
Next, you are going to take on the role of a nutritionist.
 Use the Internet to locate an explanation
and diagram of the Food Pyramid. Print out or draw a diagram of the
pyramid.
 Now research the different foods listed
below. Record what amount makes one serving, the number of Calories
in one serving, and the number of fat grams in one serving of each
item.

 Using the nutritional facts about each food and the Food Pyramid,
design what you believe to be the healthiest meal. It is important
that you take into account the amount of fat and the number of Calories
that will be consumed. Write 1 to 2 paragraphs explaining why your
meal is the healthiest.
 Make the following calculations based on your chosen meal. Be sure
to show all of your work.
 Calculations
Write your answers as fractions in simplest form.
 Total number of servings of carbohydrates out of suggested number
of daily servings of carbohydrates
 Total number of servings of fruits and vegetables out of suggested
number of daily servings of fruits and vegetables
 Total number of servings of meat out of suggested number of
daily servings of meat
 Total number of servings of dairy products out of suggested
number of daily servings of dairy products
 Total grams of fat out of suggested daily number of fat grams
 Total grams of saturated fat out of suggested daily number of
saturated fat grams
 Total grams of unsaturated fat out of suggested daily number
of unsaturated fat grams
 Total number of Calories consumed out of suggested daily allowance
of Calories
 Calculations
Your answers in decimal form.
 Percent of meal that is saturated fat
 Percent of meal that is unsaturated fat
 Percent of daily intake of fat consumed in the meal
 Percent of daily intake of Calories consumed in the meal
 What percent of your meal's Calories is from carbohydrates?
 What percent of your meal's Calories is from fruits and vegetables?
 What percent of your meal's Calories is from meat?
 What percent of your meal's Calories is from dairy?
Nutritional Challenge 3:
Now it's time to put all of your findings together and create a presentation.
Your presentation should include:
 both charts showing your nutritional intake for 5 consecutive days;
 the analysis of your nutritional intake;
 your explanation and diagram of the Food Pyramid;
 your analysis of the foods you had to select from to create your
"healthiest meal;"
 pictures of some of the foods you chose for your meal;
 the paragraphs you wrote which explain your reasoning for choosing
the foods you did; and
 your calculations based on the meal you created.
Guidance
Do you have some questions rumbling within you?
Well, if so you have come to the right place! Below are some guiding
questions or helpful hints for each Nutritional Challenge.
Nutritional Challenge 1:
Below is an example of a chart that you could use for this activity.
Remember, you will have more rows than is shown below.
Name of Food 
# of Servings 
Calories per
Serving 
Total Calories
Consumed 
Fat per Serving 
Total Fat Consumed 


















When completing the Food Analysis Worksheet, you
will run across words like mean, median, and mode. Refer to Lesson 24
in your textbook for examples and explanations of these terms.
Nutritional Challenge 2:
On average, males need to consume 2,200 Calories a day, and females
need to consume 2,000 Calories a day. Also, males need to consume about
50 grams of fat a day, and females need to consume about 40. Thus, you
should keep this in mind when you are planning out your meal!
Nutritional Challenge 3:
Some of the presentations that you could create are:
 a Web page,
 a poster, or
 a newspaper/magazine article.

Conclusion
Congratulations! You have successfully completed
your nutritionist tasks! Using your mathematical tools, you have witnessed
the power and importance of mathematics even in something as simple
as food. Yes indeed, fractions, decimals, and percents are all around
us in all that we do! Your diet is filled with mathematics, and it is
imperative for you to be able to successfully analyze different products
that are available to you. Keep up the good work!
