I WAS a little shocked when I punched in a tuna-salad recipe I use and the Omega-6's were HUGE.
From my understanding you want mostly 3's, right? What about the 9's?

From Living the Low Carb Life by Jonny Bowden: "To be used commercially, [canola oil] has to be partially hydrogenated, refined, and deodorizedm and in the process its O-3s become a potent source of trans-fatty acids. If you do use it, make sure to get organic, cold- or expeller-pressed canola oil, and only use it cold."
From Dr. Andrew Weil's website: "Omega 3 fatty acids are prevalent in fatty tissues of fish, and to a lesser extent in a plant- based sources such as walnuts and flaxseeds - in other words, they are fairly rare commodities in the standard American diet. Conversely, omega 6 fatty acids are the type prevalent in most vegetable oils, particularly soybean oil. Incredibly, production of soybean oil for food consumption in the U.S. has risen 1,000-fold from 1909 to 1999, and is part of virtually every fried or processed food Americans eat.
.....The problem with too little omega 3 vs. omega 6 is that "the enzymes that process it are very promiscuous," said Dr. Hibbeln, meaning they will build cell membranes out of either kind of fat. Cell membranes "stuffed" with omega 6 fatty acids are associated with inflammation and almost every negative physical and mental health outcome one can name: heart disease, diabetes and mental disorders of all kinds, he said."
HTH!
