Oh, I haven't been camping in tents in a long time.
In regards to food and scented items.....I've also heard (but it may be an urban legend) that a bear can be attracted to the scent of...........hmmmm.....how to put this delicately........well, used feminine hygene products.
I remember going camping many years ago, and the women were warned about being careful disposing of used stuff.
Not trying to be offensive, and like I said, it may be an urban legend, but that's what I remember.
