Mercury and Fish--the big question

[Guest guest]

OK. I just want to know people's opinions. I'm trying to weigh the

pros and cons and decide if I should eat any fish.

Are all fish, just some fish (if so, then which fish?), or no fish

high in mercury? If mercury levels are high, do you think that there

is more good than bad in the fish? What I mean is, would you still

eat a certain fish regardless of its mercury content just because it

is so high in good stuff? Are all oceans or just some oceans

contaminated? Are shellfish particularly polluted? Do fish harbor to

many " evil organisms " to be eaten raw? Are freshwater fish more or

less contaminated than saltwater? Do freshwater fish have just as

much " good " as saltwater? Are farmed shrimp and oysters okay? Are any

farmed fish okay?

On a side issue, some quite healthy primitives ate as their sole

animal food, seafoods. How did they get saturated fat? This doesn't

apply as much to the Eskimos as it does to primitives in the

tropics...

Also, I have a zinc deficiency. I want to control it with foods. The

problem is, how do I know land foods contain zinc? They could have

been grown/raised on zinc deficient soil. I see seafood as the only

sure course of action. That's why I am asking about fish, shellfish

(and oysters) in particular. Have any tips for zinc?
