True -- we have no quantitative information. However, if AA or DHA

were being oxidized to the point that you required a ten- or 100-fold

increase in their supply simply to normalize their levels, I would

think that on a normal diet you would be basically incapacitated. My

main objection was that you seemed to be assuming that the need is

somewhere around 4%, and that when the need goes up it must therefore

go up above 4%. But the need for a healthy non-pregnant,

non-lactating, non-growing adult is probably much closer to 0% than to

4%.

Selenium not only chelates mercury, but it also is involved in

gluathione activity, which counters the oxidative stress caused by

mercury and prevents lipid peroxidation, and which itself I believe

also chelates mercury.

Hmmm...Ya I guess the overall need of PUFA would still be pretty low.

I feel like I get enough plenty of PUFAs with my fermented cod liver

oil and after some calculations my total dietary intake would be

around 3-4% of the total calories. So the only point I could really

make is that mercury could be a significant source of lipid

peroxidation in the body, which we know is bad, and just agree that

the PUFA's we do get should be from a good source such as CLO.

Sometimes I forget that the benefits of EFA's (specifically omega 3s)

are usually comparing one group to another group on the Standard

American Diet.

I have a mouth full of mercury with no hope of getting them out. Am I

doomed?

I think so.

I seriously doubt that mercury will cause you to need anywhere NEAR 4%

mercury and you are not in a state of growth, pregnancy, or lactation,

your needs are probably infinitesimal.

Well if you have symptoms that closely line up with mercury poisoning

symptoms...Then it could be a problem because it could get worse with

time. Feeling doomed seems like it could be a symptom of mercury in

the brain. Nutrition and supplements can help control the symptoms

for a while. Just don't try taking any supplements made to remove

mercury from your body while you still have fillings...I've heard lots

of bad stories from people who have tried...and I tried myself and

only got worse (but not by much).
