"Fish oil" in your beef

EPA and DHA, the two "fish oils" are found in numerous places in nature. One such place is beef. Now grain feed cows and grass feed cows have different levels of these essentially fatty acids. The following two graphs demonstrate this. What these graphs clearly show is that the EPA fatty acids are anywhere between double and 12 times higher in grass feed cows. With DHA there may or may not be an increase.... and if an increase occurs it is a smaller relative increase of up to 3.5 times the level.
