A.Collection of Data Record what you eat ON PAPER
• Choose 3 consecutive days to your food intake• One (1) weekend day must be included
• Be sure to record all food and liquids consumed• Include all meal items and snacks and beverages
• Using one Food Record Sheet per day,• identify the meal/snack and the items consumed• description of each item (boiled, fried, diced, etc.)• portion size of each item
Do not include any vitamin/mineral supplements in your food record

Recording Food Intake Data
Food & Health 400:104
Help: Estimating Portion Sizes
Measure, if possible Check net weights and portions on packaging Estimating Tips:
1 cup = a baseball 1 ounce cheese = four dice 3 ounces meat = deck of cards 1 ounce nuts = one handful 1 ounce chips = two handfuls

What you need to do:1. Tell the program who you are
• Create your profile
2. Input your Food Records into the program• Track your food intake
3. View/Print Selected Reports
B. Processing DataSupertracker calculates your nutrient intake from your food record data.

Creating Your Profile
Food & Health 400:104
Tracking your Diet
• Click on the small calendar to enter the date of the first day of your food record
• Enter all foods and beverages from your written record into the Food Tracker for that day.
• Repeat for the second and third days of your food record.
Food & Health 400:104
Check Food Input Data
Check each day for errors by viewing table and graph:
Does Calorie total make sense? For example, half a piece of cake=120 Cals., and
5 pieces of cake + 1200 Cals. Be sure you enter 0.5 for one half piece of cake.
Food & Health 400:104
Select Print out only these reports:
- Meal Summary (view by meal)- Nutrients Report
- Print 3 day average nutrient report only
C. Printing Reports
Food & Health 400:104
Part II. Diet Questionnaire
Questionnaire available on class website
http://foodsci.rutgers.edu/fs104/
Interpreting Results Print out questionnaire Answer all questions
Use information from your Nutrients Report Pay attention to units To understand “Target” values( DRI’s and
Dietary Guidelines) – see textbook.
Food & Health 400:104
Dietary Reference Intakes
The analysis compares your intake to: Recommended Dietary Allowances (RDA) for 9
vitamins, 3 minerals and protein (by weight) Adequate Intakes (AI) for 3 vitamins, 6 minerals,
and dietary fiber Estimated Energy Requirements (EER) based
on age, gender, wt., ht., and activity level Acceptable Macronutrient Distribution Ranges
(AMDR) for carbohydrates, fat and protein. (as a percent of Calories)
Food & Health 400:104
2010 Dietary Guidelines
Limit non essential components of the diet such as: Saturated fat – <10% of Cals Cholesterol - <300 mg Sodium - <2300 mg (<1500 mg for +51) Alcohol- < 1 drink for women, < 2 drinks for men
(original guidelines < 10% of Cals)
WHO limits refined sugars to < 10% of Cals
New proposals for 2015 Guidelines
May ease or eliminate cholesterol limit but further limit kcalories from sat. fat (10->8%)
May ease salt restriction May put specific limitation on added sugars
Other recommendations from 2010 remain New guidelines finalized at end of this year

Food & Health 400:104Lecture 10
Understand the Math: Example
Calculations: How many grams of fat ?
.02 x 250 grams = 5 grams of fat
How many Cals from fat? 5 g x 9 Cals/ g = 45 Cals
What % of Cals come from fat?
45 Cals /125 Cals x 100 = 36%
1 cup of 2% milk: weighs 250 grams has 125 Cals
