Do you know if river caught trout has this DHA? I ask because I have a friend who keeps catching them and giving them to me. Also we go mackerel fishing now and then off the south coast of England.
Also, I presume you already know that grass fed beef has a higher ratio of omega 3 to omega 6? If you didn't I will dig out the links. Oh, here it is anyway, in case someone else is interested http://www.healthyat100.org/display.asp?catid=0,3&pageid=11
