You could use the Calorie King toolbar to look up the nutritional information of food -- I record everything I eat -- but I think that takes up too much monitor space.
Instead, I added Calorie King as a search engine in the pull-down search engine bar at the upper right hand side of my browser. Tidy and tidy!
(And if you don't use the Firefox browser, you can get it here.)
With this entry, I open the category Hacks.
