If you have foods you eat a lot and don't want to search again and again is there a way to copy them easily from one day to another?

The easiest way I have found is to use the drop down on the left hand side. Go to the bottom of the one that says recent foods for >>More (or something like that) then you can check mark all your foods you have eaten recently and click at the top or bottom a link that says add to food record. Then if you have eaten a different amount you can adjust them in your record for that day.

I will do that. I like this tool.
