Viewing analyses and graphs for a food diary—Exercise 2

Aim: To develop and demonstrate skill in viewing analyses and graphs for a food diary.

Follow the steps in Procedure 2 to complete this exercise.

As you work, compare your screens with those presented here.

  1. To start
    1. Start FoodChoices®.
    2. Open the food diary for ‘Abey’ in the ‘Samples’ folder and click on the Foods tab.
  2. View the analyses

    In the Analysis Pane, click the arrow buttons to see each analysis. Tick the relevant boxes below when you have viewed:

    General
    Profile

  3. View the different types of graphs
    1. On the Toolbar click View graphs then click each of the tabs to see the types of graphs that you can produce. As you click on each of the tabs, note the meaning of the tab headings.
      EARs  
      AIs  
      ULs  
      RDI  
      Min SDT  
      Max SDT  
      PFCA  
      PMS  

    2. The colours red and grey are used on the EAR and RDI/AI graphs. All the nutrients below a certain percentage are red, and those above or at that percentage are grey.

      What is the relevant percentage?

      In the graphs, a nutrient shaded Red means:

      In the graphs, a nutrient shaded Grey means:

  4. View the different styles of graphs

    For Abey‘s food diary, view the following graphs and complete the exercises:

    1. Graphs for Recommended Dietary Intake (RDI)
      • View a 2D horizontal bar graph.
      • View a 3D vertical bar graph.
      • Which style of graph do you prefer to represent RDIs?
        Why?
    2. Graphs for the percentage of energy from protein, fat, carbohydrate and alcohol (PFCA)
      • Examine different styles of graphs for PFCA results.
      • Which style of graph do you think is the most appropriate to represent PFCA?
        Why?

      NB: To view the percentage of energy from saturated fat, view Energy Ratios in the Analysis Pane.

    3. Graphs for percentage of polyunsaturated, monounsaturated and saturated fats (PMS)
      • Examine different styles of graph for PMS results.
      • Which style of graph do you think is the most appropriate to represent PMS?
        Why?

If your analyses and graphs look like those above, congratulations.

If not, see if you can identify why they are different. Discuss the matter with your teacher if you cannot see why there is a difference.
