Keyword exclusion

How do I tell automod to look for certain keywords, but to ignore the action if another specific keyword is also used

for example

remove the post if the title or body contains the words "apple" or "banana" but not if it ALSO contains the word "pudding", so that if someone were to talk about going to pick an apple or eating a banana it would be removed, but if someone said they were looking for recipes for banana pudding or that they had a banana that was about to go bad and wanted to know if it would be okay to make pudding with it, it would leave it alone.
