I just started fitday as well and had the same problem. I just carried my carton of eggs over to the computer and entered the amounts from the nutrition label as a "custom food". Now I know my results are much more accurate. I did the same for my mayo.

I could only find "lettuce" on fitday. Since all lettuces are not created equal, I had to look up loose leaf lettuce in a nutrition book and enter it as a custom food as well.

I find it is quicker once I add foods on this custom list, especially foods I eat frequently such as butter, eggs, and lettuce.
