Found this info about nutrition and metal toxicity.... it has a list of fish that are less likely to contain high amounts of mercury...but many of us are super sensitive and can tolerate none.

MERCURY NUTRITION GUIDELINES
Eliminate caffeine.
Eliminate sugar and alcohol.
Eliminate fish and shellfish from diet, especially those that historically contain the highest levels of mercury.
AVOID
Shark
Swordfish
King mackerel
Tilefish
Tuna (including canned)
Sea bass
Gulf Coast Oysters
Marlin
Halibut
Pike
White croaker
Walleye
Largemouth bass

NOT MORE THAN ONCE PER MONTH
Mahi mahi
Blue mussel
Eastern oyster
Cod
Pollock
Great Lakes salmon
Gulf Coast blue crab
Channel catfish (wild)
Lake whitefish

LOWEST

Catfish (farmed)
Blue crab (mid-Atlantic)
Croaker
Fish Sticks
Flounder (summer)
Haddock
Trout (farmed)
Salmon (wild Pacific)
Shrimp (although shrimp fishing and farming causes serious environmental damage)

Avoid external sources of mercury including petroleum products, Bounce fabric softeners, fungicides, cosmetics, and hair dyes. Read labels: phenalmercuricacetate and thimerosal are other names for mercury.
Eliminate milk.
Eliminate pork.
Eliminate cigarette smoking.
Enjoy:
Increase fiber consumption, which is important to bind toxins in the digestive tract.
Drink 8 eight oz. Glasses of water/day.
Eat plenty of eggs and butter. The emphasis on animal protein is because of its concentration of sulfur bearing amino acids and lipids (fat). Mercury has an affinity to both of these chemical groups. You may use MSM 1000mg 3x/day if you are allergic to eggs.
Supplement your diet with probiotics like lactobacillus acidophilus capsules.
Steam in a sauna or steam bath for 20 minutes 1 to 3 times per week as directed by your healthcare provider. Your skin is the largest excretory organ in your body and one of the safest routes of detoxification.

Hi Sandi, thanks for outlining that. VERY helpful and informative. I have to say I have been cheating on my diet and I am in a real state. i feel drugged and very ill as though I'm in a stupor. I don't know if it's the diet cheating, or what. I gather it might be part of it.

I'm going to make sure I stick to it, I do not like how I'm feeling at all. It's bad enough to be continually toxic with mercury and/or other materials in my mouth and body, and to have possible jawbone infections, but to let my diet slip seems to end up being disasterous.
