The more intelligent way to deal with excess PGE2 is to let your body
do what comes naturally, that is, when you stop consuming dietary PUFAs
(except in trace amounts), your body makes what is called Mead acid,
and then you can no longer make PGE2 at all. Instead, your body makes
prostaglandins that are much more biochemically stable, and hence,
safer by a large order of magnitude. Someone who posts here (and
appears to have scientific credentials) has disagreed with me on the
ground that Mead acid is "too inert," presumably when compared to
arachidonic acid (which is used to make PGE2). I agree completely, but
that's not the point, which concerns the clinical implications.
Derivatives of arachidonic acid may be useful in emergency medicine,
when very potent substances are needed, but in normal, day-to-day
activities, the body does not need such potent and unstable substances.
There are many studies that support this claim, and there are hundreds
that implicate arachidonic acid in the cause of many "diseases,"
directly or throught the metabolites, especially PGE2 and LTB4.
Now you know what is going on, down to the molecular level. If you
choose to ignore it, you will only hurt yourself, because you cannot
play around with such biochemically potent substances on a regular
basis and think that you will not get one or another "chronic disease."
Fish oil is even worse (in the sense that omega 3s are generally
considerably more unstable than omega 6s), but it does disrupt
arachidonic acid metabolism (though there are some contradictory
reports about flax oil/linolenic acid), at least temporarily. It's
very similar to the effects of chemotherapy, and if you look at the
survival statistics of those who receive strong doses of chemo, you
know what a bad idea this is. Many suggest that fish oil "cures
cancer," when in fact the cancer cells can't even deal with the
biochemical activity generated by fish oil. If you eat this stuff,
realize that your MO is that "it takes a monster to kill a monster,"
and don't complain when the monster you thought was your friend decides
to take you down.
