I've been told that frozen vegetables are frozen soon after harvest and as such don't get sprayed with as much preservatives. I'm also told fresh vegetables are sprayed with extra preservatives so they'll look better in the store.
I tested the waters with this claim once with a biology grad student (although she dealt with spiders stealing things). She seemed to agree with the claim while noting that vitamines in food are destroyed or diminished when frozen.
Is it true that frozen vegetables are healthier than fresh ones to eat, for the reasons mentioned above?
New Oxford American Dictionary:
Fresh: (of food) recently made or obtained; not canned, frozen, or otherwise preserved
