Food Nutrient Calculator: Detailed information
What is FNC?
Click on the thumbnail below to view FNC's main form.
The grid in the upper left corner of the form contains a listing of all the foods in the database. The lower grid displays the nutrient values for the currently-active food (i.e., the one with the pointer to its left in the upper grid). The other fields on the form supply additional information about the current food.
1. Searching for a specific food and displaying its nutrient values
To find a particular food, click on the 'Search (list)' button (or press F8): a 'Locate' dialog box will appear into which you enter a search criterion. Click on the thumbnail below to see a full-sized image of the dialog box.
Click on the dialog's 'First' or 'Next' button (or press Enter); FNC will search the database for food descriptions containing any of the word(s) contained in your search criterion, and display them all in a new dialog box. Click on the thumbnail below to see a full-sized image of the dialog box containing the search results.
Scan the list in the dialog's grid and locate the food you're interested in. Then double-click the food description and voila! -- the main form is redisplayed with your selected food active, and its nutrient values shown in the lower grid.
2. Displaying nutritional values for food weights other than 100 grams
FNC can automatically display nutrient values for up to 15 additional weight values for any given food. (The exact number varies greatly in the USDA data: most foods have just one or two additional weight values.)
Click on the 'Other Weights' button on FNC's main form: a dialog containing a grid will open that shows up to, and at least, the first five nutritional values for weights contained in the USDA database. Click on the thumbnail below to see a full-sized image of an example.
3. Displaying nutrient values for a user-entered food weight
Clicking on the 'Calculate' button brings up a dialog box into which you can enter a custom weight for the currently active food. Click the thumbnail below for a full-size picture.
Click on the dialog's 'OK' button (or press Enter): FNC will do the necessary calculations and display the results in another form. Click the thumbnail below for a full-size picture.
4. Exporting data
Wherever data are displayed in FNC, you can save them to a file for later use in other programs such as word processors and spreadsheets. Just click on the 'Export' button (), choose a file format from the dialog that appears, and indicate whether you want to send the file to the screen or directly to a file on disk.
5. Printing reports
As with exports, any and all data that you see displayed in FNC can be printed in a report. Wherever you see the 'Print' icon () on a button (just about everywhere!), click on the button to open a report preview window. You can scan the preview window if you wish, or just click on its 'Print' button (). Click on the thumbnail below for a picture of FNC's print preview screen.
6. Custom selection of nutrients for display
By default, FNC displays values for all 82 nutrients. If, for whatever reason, you wish to suppress the display of values for one or many nutrient values, you can do so using FNC's nutrient selection facility.
