An alternative to hiding the news feed is unfollowing (not unfriending) people. I've unfollowed all but my immediate family and about 10 of my closest friends. None of them really post memes, only interesting life events/travel. Deleted the app from my phone too. For me this is the best solution. My main Facebook use case is photos. I don't like to take them and my friends aren't going to waste time emailing me them when they can put them on Facebook for everyone. If it wasn't for photos I would have deleted it.
