How much Omega 3 is recommended each day?

I want to make sure that I get enough of all of the essential nutrients each day. I hear that now they are recommending people get plenty of Omega 3 fatty acids in their diet, so I am trying to find out how much Omega 3 is recommended each day. Can anyone tell me where I can go to find out this information? I really want to find out more about this. I also want to find out what are my best options for getting Omega 3 fatty acids in my diet, besides fish oil capsules. I like to eat food rather than take pills.
