duplicate items in food list

Options
I have some duplicate items in my recent foods list that have incorrect nutrition information. How can I delete a food from my recent foods list without permanently deleting it from the database?

For example, I have an atkins caramel nut chew bar listed twice. One is listed as net carbs and the other is listed as grams. I use the one that is listed in grams and want to delete the net barbs one.

There are probably others in my frequent foods that are the same food item but are worded just a little differently and would like to delete one of them. There are also some in there that the nutrition information is incorrect on so I would like to delete them as well..

There are some other things that I had tried as foods but doubt I will ever eat them again. How can I delete them from my recent foods list so that I can "clean up" my list of recent foods?
