Check if the content of a file is already in a git repository

How can I check, if a file with the same content is already under git version control?

That seems like a rather odd thing to do (why not just add it?) but:

git cat-file -t $(git hash-object -t blob foo)

will fail or (very unlikely) print something other than blob if the contents of file foo are not already in the repo. That gets you part-way; next, you have to find out whether that hash-ID is referenced (i.e., that it is not a dangling blob), and if so, by what references. It might be referenced by the index (only, or in addition to being in some tree in some commit). To see if it's in a tree in a commit, clone the repo to a --bare clone (if it's not already one) and see if the ID is (still) valid there.
