How Do I Remove Food Items From My List I Dont Use Any More

I have selected some things that are the wrong brand /type nutrition wise. How do I remove them, I can't find an Edit Button.

How do I answer messages? I cant find the way to do that and I have 3 messages waiting!!

Press back on the item that you have put wrong, another page is going to appear, screw down until you see this kinda yellow square, on the bottom of that square theres written save, refresh delete or cancel, you click on delete and it'll be gone

Do you mean the back space button? I went to the food list and put a check mark and then pressed the back space button but nothing happened. Could you give me a little more detail? thanks

Click on what you don't want, ok! This page whit a lot of information about that item appears , scrol down, on the right side of that page theres this yellowish square. On the bottom of that square you click on delete , that particular food is going to be deleted (in that square you can make any type of change that goes on your nutrition diary )
