DATA ANALYSIS

There are 2 options available to analyse dietary data

Dietary intake data OPTION 1
This option requires you to download the FoodChoices software program from www.foodchoices.com.au The FoodChoices program requires Windows XP or Windows Vista. It is not suitable for Mac users unless you have a Windows interface. Please refer to the tutorials and user guides available on the website under the ‘how to’ tab.

1. Enter your 24-hour food record into FoodChoices to analyse the selected nutrients and energy content of your 24-hour dietary intake. You will not need to complete table 3.
2. Record the average daily intake of the following selected nutrients only; protein, total fat, carbohydrate, alcohol (if consumed), dietary fibre, water, iron, calcium, sodium and energy, and compare these to the appropriate NRVs in Table 4.
3. Record the relative contribution to energy (%kJ) in your average diet coming from protein, fat, carbohydrate and alcohol (if consumed) to the total energy in the diet and compare to the Acceptable Macronutrient Distribution Range (AMDR) in Table 5.
4. Record your energy intake data in Table 10.
Dietary intake data OPTION 2
This option requires you to access the NUTAB 2010 database from http://www.foodstandards.gov.au/science/monitoringnutrients/nutrientables/pages/default.aspx and enter each of your food items on the searchable database. Please refer to the explanatory notes and frequently asked questions on the website.

1. Enter your 24-hour food record into NUTTAB 2010 to analyse the selected nutrients and energy content of your 24-hour dietary intake. Record results in Table 3.
2. Calculate the average daily intake of the following selected nutrients only; protein, total fat, carbohydrate, alcohol (if consumed), dietary fibre, water, iron, calcium, sodium and energy, and compare these to the appropriate NRVs in Table 4.
3. Record the relative contribution to energy (%kJ) in your average diet coming from protein, fat, carbohydrate and alcohol (if consumed) to the total energy in the diet and compare to the Acceptable Macronutrient Distribution Range (AMDR) in Table 5.
4. Record your energy intake data in Table 10.

Physical activity data
1. Complete Table 6. As you account for each 5 minute interval, cross it off your data sheet. The total time must be 1440 minutes (i.e. you must account for every minute of the day).
2. Calculate the average daily estimated energy expenditure (EEE) from the 24-hour activity records and energy cost of activity in Table 10.

Estimated Energy Requirement (EER)
3. Determine your BMR (BEE) using Schofield’s equation.
4. Calculate your average daily estimated energy requirement (EER) in kJ/day by multiplying BMR x Physical Activity Level (PAL) (see Table 9) and enter into Table 10.
Energy balance
5. Calculate your energy balance (energy intake minus energy expenditure) in Table 10.
Anthropometric data
Record your height (m), weight (kg) and age (yrs). Calculate your BMI (kg/m2). Record all results on Table 10.
