In reply to do you think the SDA makes as much EPA as they say » Larry Hoover, posted by iforgotmypassword on July 6, 2009, at 15:41:27
> it does? they have some article or something that explains the reasoning, i guess i should try to get a copy. how solid do you imagine the logic being?
I don't understand what you're referring to here.
> are there any other factors in this (SDA to EPA conversion) that must be present for conversion to be significant? like how estrogen increases ALA to EPA conversion.
The most important would be to have low intake of omega-6 fats, something the Western diet is far too high in.
> if 1g of ALA is really in 5mL of that stuff, at least a bit has to make EPA, doesn't it? perhaps especially considering the fact that i take HRT. i've heard these 5%-10% conversion numbers, i don't know where i got them, how valid they are... some EPA has to come out of taking a full gram of EPA; to predict, any amount or range you would consider valid?It's generally accepted that 5% conversion of ALA to EPA is about all that can be expected. Individual variability would probably put it at between 1% and 15%, at the extremes. Variables include gender, genetics, and diet. The only one of those you can do anything about is diet. Omega-6s and omega-3s compete for the same enzymes. You want the omega-3s to be successful, or the omega-6 family based on gamma-linolenic acid, but not the omega-6 family arising from linoleic acid, which terminates in the pro-inflammatory arichadonic acid.
