Computer programs for nutrition calculation

Users guide

This users guide aims to provide an introduction to the program. There is much more functionality than that described here. The manual will gradually be expanded to eventually become complete.

1. Start Dietitian Net

Browse to Diet and Nutrition Data’s website and click Dietitian Net and then on the version of the program you wish to start.

You can either download an installation file and install Dietitian Net on your computer or you can start the program by clicking the link “Start Dietitian Net”

If you use the latter option, you must have Java installed on your computer. Java is a software platform that Dietitian Net must have in order to function. In the latter option, Java is included in the installation and you do not have to care about whether you have Java or not. Functionally, it does not matter which option you choose. There are cases when you have to use the “Start Dietitian Net” link for the program to work. It depends on how the network your computer is connected to is configured.

It does not require administrator rights to install the program on the computer and when the installation is complete, start Dietitian Net like any other application on your computer. On a Mac, from there you placed it (the installer suggests the desktop) and on Windows from the application menu (it will not be created a shortcut to the desktop).

When the program is started, you will see a login screen where you fill in your account details (in the free version you choose which language to use).

null  null

If you have started the program by clicking on the “Start Dietitian Net”link, ie that you have not chosen installation option, then you can choose to create shortcut to Dietitian Net by checking the box below the password field.

2. Begin using the program

null

There is a small blue button with a question mark for each function in the program null. If you click on these it will open up a help window where the function is explained.

 

2.1 Basic settings for a nutrition calculation

Basically there are three components that control nutrition calculations:

  • Norm: indicates how much of the nutrients that you should eat.
  • Meal Distribution: specifies how much of a day’s intake of food to be delivered in each meal
  • Foodstuffs: foodstuffs in each meal

The program calculates how much of each nutrient you eat in a meal and then compares this to the percentage of the norm for the nutrients that the meal distribution indicates.

An example: A breakfast contains 100 units of nutrient X. The norm says that you should eat 400 units of the nutrient X in one day. Meal distribution indicates that 25% of a days food intake should be allocated to breakfast. You have then been eating the normalized value of the nutrient for breakfast.

 

2.1.1 Setting up the norm

Click “Norms” and then “Choose the default norm”.

Select the norm consistent with the person that the calculation is performed for, and then click “Save.” You can choose to have different norms for different days.
null

2.1.2 Setting up meal distribution

Click on “Calculations” and then “Meal distribution”.

Set the percentage of nutrient intake derived from the respective meal and then click “Save.” You can choose to have a different meal distribution for different days.

One can easily see the share a meal has of the meals for the day by holding your mouse pointer over a meal button.

2.2 Adding foodstuffs to the nutrition calculation

2.2.1 Selecting meal and day

When Dietitian Net starts the breakfast day 1 is selected. Change meal by clicking the meal buttons and the drop down menu for days.
null

You can enter information about the day by clicking on the button labeled “Day”.

null

2.2.2 Selecting foodstuffs databases

Mark the foodstuffs databases to search out foodstuffs from.

 

2.2.3 Search for foodstuffs

You search for foodstuffs by typing a few letters in the name of the food, such as milk. The program displays all the foods that contain the word milk. First is the food that begins with milk, followed, in alphabetical order, the foods with the word milk in their name, such as whole milk. You can limit the number of options by typing two words, eg “app ju” to get just the foods that contain both letter combinations, such as apple juice.

When you have found the foodstuff you are looking for then double click on it to send it to the meal. You can also highlight the desired foodstuffs and press the “Enter” key, drag the food to the meal list or press the button “Add”.

2.2.4 Quantity, units, gram and price / kg

You can either use the arrows or type the number of units of the foodstuff.

 

Choose unit.

 

You can either use the arrows or type the number of grams of the foodstuff.

 

If you want to price functionality in the program, you activate that under File -> Preferences. Then you can fill in pricing so you can easily budget meals.

2.3 Charts etc.

2.3.1 Bar chart

Bar chart for meal

The result is shown in the form of charts and numbers. Each line in the foodstuffs list has its own color and the in the bar chart you can see what contribution each food provides to the different nutrients. In the chart below you can see eg the cheese, blue line, providing plenty of protein and fat. When one bar reaches 100% mark it means that the meal has given so much of the the nutrient that the norm prescribes.

Bar chart for day

The color scale will change if you choose to display the bar chart for an entire day. The colors will then indicate which meals that provides what.

Bar chart for days

The color scale will change if you choose to display the bar chart for all days. The colors will then indicate which days that provides what.

Missing values

If you use a product that is not fully declared the button “Show Missing Values” will turn red. If you click on the button you can determine which foodstuffs and which nutrients that is missing information.

2.3.2 Pie chart

In the pie charts you can see both the real and the ideal energy distribution according to the selected norm.

2.3.3 Time chart

If you set a timestamp for the meals you can see how different nutrients are distributed throughout the day.

In the time chart, there are also functionality for insulin dose proposals and blood sugar control.

2.4 Energy calculation

The energy requirement can be calculated in different ways. Norms indicates average energy needs for an age group. You can change the energy norm by clicking on the button “Energy” as shown below.

Activities

You can calculate the energy needs based on activities. The chart below shows the basic requirement with dark green color and the the energy needed for activities with light green color. The red bar shows the energy that the day’s food provides.

Specify the desired energy use

You specify the total energy and then how you want it to be allocated between energy providers including fibers, but not alcohol.

Harris Benedict Equation

One can use the Harris Benedict Equation for calculating energy requirements.

Mifflin-St Jeor Equation

One can use the Mifflin-St Jeor Equation for calculating energy requirements.

2.5 Save, open and send calculations

2.5.1 Save calculations

You save a calculation by clicking Calculations -> Save

If the calculation is previously unsaved, the program will want to save the calculation with a name and for a client. If you use the free or the group versions of the program, it’s only one name you need to provide the calculation. You can also save the calculation for an existing client.

2.5.2 Open calculations

To open a previously saved calculation click Calculations -> Open

Select the client that has the calculation. Mark the calculation. Press Open. In the the free and group versions of the program does not use clients.

2.5.3 Send calculations

To send a calculation, click on Calculations -> Send calculations. To send a calculation, you must have received the recipient’s username in Dietitian Net Pro. Instead of the username, you can use a six-digit code that is unique to each user. You’ll find your personal code to Dietitian Net Pro under File -> Preferences.
Users of the the free version of the program can easily send food diaries to the dietician / nutritionist.

In Dietitian Net Pro you mark which client the calculation is under, mark the calculation, fill in the recipient’s username and press Send.

 

In the free and group versions of the software it looks a little different. You mark the calculation to be sent, fill in the recipient’s user name (or code) and your contact information.

When someone sends you a calculation you can open it like any other calculation. The submitted calculations are marked with “(submitted)”.
