The Single Food

The Single Food screen is good place to start. By clicking in the ``single banana'' icon, this screen in displayed:

This allows you to enter a particular food and receive a report about its nutrient content.

Searching for a Food

Gnutrition can only analyse the foods present in its database. Press the ``Search'' button, to show the search window:

As this box shows, you may search by the text name or by the nutrient content.

Search by Text

In this example, I searched by the word ``apple'' The database produces dozens of options for this word, such as ``Babyfood, fruit, applesauce, strained'', or ``Pie, apple, prepared from recipe'' This are displayed in a tree format, with the first word forming the header, the second the sub-header, etc. You must explore the tree to find the one you what, cicking on the little pluses, explodes the sub-hierarchy of foods. In this example, I have selected ``Apples, raw, with skin'':

Search by Nutrient Value

In the ``Search'' window, ``Nutrient Search'' can be selected:

Foods are selected by their nutrient content. ``Content'' can be assessed by grams (weight), or calories (energy).

You can maximise nutrients, selecting foods rich in those nutrients, or minimise nutrients, selecting foods low in that nutrient.

The ``constraint'' refers to a weighting given to each nutrient in computing its score. So nutrient with a constraint of 3 will be three times as important in calculating the score, as one with a constraint of 1.

The minimised nutrients have a negative constraint, as they subtract from the score. The search gives the foods with the highest score by this method.

The foods are displayed in a tree as for the ``Search by Name'' box.

Back to The Main Window

When you have found the food you what, press the ``OK'' button, and you will return to the main screen with your food selected:

You must first select the unit you are measuring in, in this case I have selected "large" (i.e. large apple), and the amount, in this case one. Results are shown for lots of nutrients. Different classes of nutrients are selected by the tabs ``Macro-nutrients'', ``Minerals'', etc.

To understand what all these mean, refer to the Nutrient Notes
