I need a quote similar to "Eat the fish, spit the bones".
Basically, I want to convey this to someone - "Look, on the internet you'll find 1000s of articles explaining this topic. Not all will be useful, and some might be explaining this in a different context as well. Don't follow anyone blindly, gain the relevant information from them, but figure out which are not useful, and ignore them."
I need a more subtle version of "Eat the fish, spit the bones" since the other person is vegan and won't appreciate me using such quote even for conveying my point.
