Now there is an easy, accurate way to find out how many calories are in that omelet and glass of orange juice you had for breakfast. The U.S. National Agricultural Library has posted a database containing comprehensive information on more than 6000 foods. Besides calorie counts, it also lists protein, carb and fat calculations, as well as the Recommended Dietary Allowance percentages for half a dozen important vitamins and minerals.

It even analyzes the amount of saturated fats, trans fats, cholesterol and sodium in each item so you get an instant snapshot of how healthy it is.

Best of all, this tool is available free of charge and loads in seconds right into your computer or Palm device.
