The ALA in flax seeds doesn't have "much effect" on the amount of DHA (and EPA), but according to this site it does have "some effect"...
"the human conversion of ALA to EPA and DHA is somewhat slow, only about 15% of ALA converts to EPA and 5% DHA (Cunnane 1995, Nutrition Advisory Panel, 1995)."
Is that true?
Flax seeds, for instance, contain 18 grams of ALA per 100 grams, and that should *theoretically* give 2.7 grams of EPA and 0.9 grams of DHA, according to the pbuttage I've just cited.
good sources of dha 917I don't know. Most people want to reduce the total fat and calories in their diet, so if they want more DHA...
Does that (more omegas in the skin) apply for other fishes as well?
I read that the fish oil could be contaminated as well, unless it comes from molecular distillation... What do you think?
What about purslane?
Purslane (Portulaca olearacea), a vegetable used in soups and salads along the Mediterranean basin and in Middle Est, is the richest source of LNA of any green leafy vegetable examined to date. Moreover, it is one of the few plants known to be a source of eicosapentaenoic acid (C20:5 n-3, EPA, also known as Timnodonic acid)
Anyway, I gather that a better balance of ALA vs. LA is usually recommended... and that some studies gave good results in heart disease prevention with a Mediterranean diet rich in ALA...
Therefore, also the theoretic calorie count is not real, in this case?
Whole flax seeds taste good in muesli, though... :)
You can grind the seeds in a coffee grinder. After grinding you should refrigerate.
Or you can sprinke the flax seed meal on some foods... :)
