Still though, I must say that most people do not have grass-fed animal fats

available. The statements in NT would do well to be qualified to make clear

to mothers the importance of either grass-fed animals or fish-oil for the

linolenic acids when pregnant and breastfeeding.

Also, it would be interesting to know more--I have read that the wild animals

eaten by traditional peoples were more lean than our farm-raised animals.

Would they have stored their linolenic acid in their fat deposits or organs?

Anyone know?

>>>3. I have no idea which EFA's play a role in lactation, but animal

fats contain the long chain omega-3's and the bodies conversion rate

from LNA to EPA/DHA is horrible (that delta-6 desaturase has probably

done in many vegans!) I have one study that shows a 6% and 4%

conversion rate for EPA and DHA, and another that finds that only

0.2% of plasma LNA ends up as EPA or DHA.

***, animal tissue also contains LNA. I've just been discussing this

issue on another list coincidentally. There are factors that do interfere

with conversion to longer chain FAs, but I have to think if it's there, then

we *should* be able to convert it. Although, obviously we don't all convert

very efficiently. I would like to see the total diet of the test subjects in

the studies that showed such low conversion rates. I think the total lipid

profile of the diet would influence conversion of LNA, especially the

presence of high amounts of LA whic competes for D6D, and is thought to be

more intense, thus perhaps 'beating out' LNA for the enzyme. Are the studies

you mention online? I'm eager to read them. If not, and you have digital

versions, would you be so kind as to forward them to me?

They may have been more lean as you put it but they also went for older animals

that had more fat and consumed all the fat there was on the animal.

hey, this time I remembered! Try message #6942 (animal fats and

efa's - justin) for just the omega-3 stuff, or #6401 for the whole

cholesterol spiel.
