How to delete food from "my foods" section?

Options
This is about the "my foods" section of MFP. I only have 2 foods listed, but I can't delete the only one that I will never buy again. I want to add more, but I want to delete that one and there is no "delete" button. I try to "edit" (which is my only option), and it won't allow me to put 0's everywhere. It wants a quantity.
