How many omega 3s and 6s are necessary?

I see some places saying that you should get 1.6g of u3 and 17g of u6. I see other places not giving a specific necessary amount per day, but saying the a ratio of 1:4, or even 1:1 of u3:u6 is optimal. I know there's a lot of dodgy information out there on the subject, so I figured I'd look for some input. In looking at my diet it looks like I'm getting nowhere close to 17g of u6 a day, but my ratio of u3 to u6 is 1:1 to 1:5 on any given day. Should I do anything?

For the curious, I typically only use olive oil for cooking, and I use very few condiments in general, and the ones I do use are typically sweeteners which contain no fat at all. The only major sources of omega 6s in my diet, as far as I can tell, are poppy seeds, olive oil, and eggs - and I eat pastured eggs, so I'm not even sure I'm getting much omega 6 from them, as they're coming from chickens that aren't have soy crammed down their throats in factories.
