Yup, I sure do!
Look at nutritiondata.com. They have a great "pantry" feature where you put all the things in that you would normally have in your kitchen, enter the amounts of each that you use and it spits out all, and I do mean ALL the information you could ever want! I love it. Makes keeping track so much easier.
Just go to their home page, run your curser over catagory 2 "compare multiple foods" and you will see the link to the pantry page with instructions on how to use it.
Just make sure not to delete your cookies because they store your info in one. But if you need to "clean out" your computer cookies they have an export feature where you can send all the information to yourself in an email for safe keeping, then when you are done cleaning simply copy your email and put it back into the site!
