Re: Cold-water fish, hot questions ;)

Long chain omega 3 PUFAs, such as EPA and DHA, are only "beneficial"
for a short period of time due to their inhbition of the metabolization
of the long chain and very dangerous omega 6 PUFA, arachidonic acid.
Because it is assumed that your diet is high in omega 6s, as almost all
Americans' diets are these days, you are being told to "supplement"
with toxic substances with EPA/DHA. A recent study, for example, found
substantial immune system suppression from "moderate" amounts of EPA.
You need to worry at least as much about toxicity from the EPA/DHA as
you do metals/pollutants. In fact, these fatty acids make your body
much less resistant against various metals/pollutants. A recent study
did not find the iron overload "diseases" among Asians on coconut oil
diets, for example. Search this group for montygram and read through
some of my posts for mor details. If you have any questions, feel free
to ask.
