Fields
If you want to see specific fields in results lists, you can open the "Fields" submenu and click whichever checkboxes you want to appear.
This can be useful for narrowing down foods, however if you want to *compare* foods, using the Compare Tool is probably a better idea.
You can also add ratios of two nutrients as fields (for example, fiber to total carbohydrates). For more information about that, check out Ratios.
