Omega-3 and Omega-6 Food Sources
Finding information about how much omega-3 and omega-6 fatty acids are in a food or oil isn't an easy undertaking. The information is not all that readily available and takes some time to find. Below is the start of a list of foods and fats/oils to start with - as I find more information, I'll update here and include the sources of the additional information.
For now, I wanted to provide a list to start with from the information I have gathered. I ask my readers to add to this list in the comments section - place links and any levels of omega-3/6 tested in the comments for other readers to use!

If I remember correctly, I got the link to this blog page from another thread here at Paleohacks. I omitted the non-Paleo items on the list, such as vegetable oils. I apologize for the spacing. The line spaces and returns I type do not appear in the post.]
