FYI, the author mentions "flax oil also fits the bill", which from what I know, and from the most recent Nutrition Action Newsletter (nonprofit consumer information organization), isn't true. It's in their latest (November) issue, but I can't find a link to it online. http://www.cspinet.org/nah/index.htm http://www.cspinet.org/nah/index.htm Flax oil I believe contains mostly omega-6, which people aren't generally as needy of with our current diets.

The problem with the omeaga-3 in flax oil is that it's ALA, while we really need EPA and DHA. Although the body can convert ALA, it doesn't do so with great efficiency. http://www.marksdailyapple.com/omega-3-dosage-sources/ http://www.marksdailyapple.com/omega-3-dosage-sources/

  From what I've heard the conversion from ALA to EPA is OK but conversion to DHA is a lot more variable.

As I understand it a high amount of Omega-6 means that you cannot absorb the omega-3. From WP: > Thus accumulation of long-chain n−3 fatty acids in tissues is more effective when they are obtained directly from food or when competing amounts of n−6 analogs do not greatly exceed the amounts of n−3. Fish oil contains a higher ratio of omega-3 to omega 6 than other sources (flax seed). Also, fish oil contains Vitamin D which is very good for teeth (if you get enough vitamin D, holes in teeth repair themselves). A lot of fish oil is also specified as "cod liver oil". So I don't think that it uses the above fish and i don't think that the cod livers is used in food (so it is a byproduct).

  > if you get enough vitamin D, holes in teeth repair themselves I'm interested - do you have a citation for that? I've read that teeth can repair themselves to some extent in Weston A. Price's Nutrition and Physical Degeneration.

    I read the following in wikipedia (http://en.wikipedia.org/wiki/Omega-3_fatty_acid http://en.wikipedia.org/wiki/Omega-3_fatty_acid): > Flax, like chia, contains approximately three times as much n−3 as n−6. > Oils from these fish have a profile of around seven times as much n−3 as n−6. Obviously WP is not infaliable and needs to be corrected. (I usually drink Flax seed oil because fish oil seems grouse).
