Diet Analysis Project Instructions Scientists have developed standards (DRIs) for the amount of nutrients needed for healthy human functioning, and tools for planning diets to meet these needs. Evaluating the nutritional status of an individual can help to identify their nutritional needs and can be used to plan diets to meet those needs. The purpose of this project is for you to have the opportunity to perform a nutritional assessment on a friend or family member (not on yourself!) by administering a health history questionnaire and 3-day food diary in order to analyze and assess their dietary intake using iProfile diet software. The project has three parts: Part 1. Data Collection – Health History Questionnaire and 3-day Food Diary Part 2. Data Processing and Analysis – Analyze food diary using iProfile and save reports Part 3. Interpretation of Results – Answer questions and summarize your participant’s nutrient intake with recommendations for improvement. **Please carefully read all instructions and all documents included in the project before you begin. Part 1. Data Collection Ask one friend, family member, teammate, roommate, partner, husband/wife (you get the idea!) to consent as your “participant” in your project. Your participant should have no major health conditions or chronic diseases (food allergies are okay) and should be over 10 yrs of age. You will be analyzing their diet and making recommendations. 1. Using the Health History Questionnaire (HHQ) provided, ask your participant all questions to gain a general overview of their health. It is best if you phone or talk to your participant face-to- face and ask them the questions or sit with them while they complete the questionnaire. If you print the HHQ for your participant to complete by hand, keep in mind you will need to either re- type their answers or scan and save their hand-written HHQ on your computer to upload on UR Courses as part of your project mark. 2. Using the 3-Day Food Diary provided, clearly explain the instructions for completing an accurate food record to your participant (see the food diary for instructions + your text and Unit notes). The usefulness of your analysis depends on the accuracy of your participant’s data. Below are some instructions you should reiterate to your participant: a. Record your food and beverage intake for 3 consecutive days. Include 2 weekdays (Mon-Fri) and 1 weekend day (Sat or Sun). These days should follow your typical eating habits as much as possible. b. If you take vitamin/mineral supplements do not include them in your food record (the use of these supplements will be addressed in Part 3). If you take a protein supplement include this in your food diary (try to be specific about amount, e.g. scoops of powder, and brand). c. Be sure to include all beverages consumed – these are often overlooked.
d. Keep your food record with you and record throughout the day. *It may be helpful to provide your participant with a hard copy of the food diary so they can record throughout the day (hand-written). You will need to either re-type their answers or scan and save their hand-written food diary on your computer to upload on UR Courses as part of your project submission. Alternatively, if your participant has access to a computer you can send them the food diary and they can complete it, typed, and send it back to you for analysis. e. If possible, use measuring cups/spoons to determine portion size and check net weights/serving sizes on packages if available. If measuring is not possible, there are tips for estimating in the food diary form as well as in your text (Chapter 2). Part 2. Data Processing and Analysis 1. Access iProfile software using your access code. You will be prompted to register with a name/email/password. With iProfile, you can create multiple profiles or participants – so if you ever want to evaluate your own diet or another friend’s diet, or your entire family, feel free to use the software as you like! It is not a one-time use. 2. Instructions for entering food data and analysis can be found in the iProfile Tutorial on UR Courses and there are helpful instructions within iProfile. The instructions I’ve provided include a list of reports you will need to save and upload for your project. Part 3. Interpretation of Results 1. First, review and interpret your results. Check each day for errors by viewing the days and the Intake Compared to DRI report. Does the Kcal total make sense? For example, half a piece of cake = 120 kcal and 5 pieces of cake = 1200 kcals. If your participant’s total kcal intake was 5000 kcal one day and 1400 kcal another day, you may need to go back and check if you entered a food and its amount incorrectly. Here are some common mistakes to avoid: Coffee cream this is not coffee with cream in it. It is cream used in coffee. OJ concentrate one cup = 4 cups of orange juice. Enter orange juice from concentrate instead. French fries, SVG represents a serving of fries, not just one fry. Snack foods please note correct grams or ounces on bags of chips etc. 2. Remember you will compare your participant’s results to their own specific DRIs for vitamins and minerals, but there is no specific DRI for CHO, fats, protein, only acceptable ranges (AMDRs) based on recommended Kcal intake. Determine if your participant fits within these ranges by viewing the Macronutrient Distribution report. 3. The reports listed below and in the iProfile Tutorial will be used to answer the questions in Part 3. See the iProfile Tutorial and box below for the list of reports you must save and submit with your project. Please save all your work. You can save and return to finish your work at any time within iProfile. 4. The Single Nutrient report from the analysis allows you to investigate foods containing a specific nutrient and does not need to be saved and submitted with your project, but you will refer to this data for several questions in Part 3.
What do you hand in? 1. Part 1: HHQ and 3-day Food Diary – 5 pts 2. Part 2: Print out of iProfile nutrient data analysis including: 10 pts a. Intake Compared to DRI (3-day average -*Complete View*) b. Macronutrient Distribution (3-day average) 3. Part 3. Answers to questions (these should be typed below the question in bold and numbered following the same question format). Do not delete the question and type your answer. – 20 pts ** Save and name all documents to upload following the rules below: ❖ HHQ should be in word doc. or pdf. Save it as “HHQ_yourstudentname” – e.g.
HHQ_KatherineMcLeod. ● 3-day Food Diary should be in word doc. or pdf. Save it as e.g. Food
Diary_yourstudentname (see above). ● Intake Compared to DRI and Macronutrient Distribution reports should be in pdf. You
can choose to download and save them this way from iProfile. Save these with the name of report and your student name.
E.g. Macronutrient Distribution_KatherineMcLeod ● Part 3 should be word doc. only so that I can make comments directly on your
project if needed. Pdf. will not be accepted for Part 3. Save it as Part3_yourstudentname. E.g. Part3_KatherineMcLeod
Do not wait until the last minute to complete the project! You will lose marks if you do not submit the correct documents. Keep in mind your participant’s information will be kept confidential.
