Food allergies to things that are recommended

... like seafood.

I keep hearing of the benefits of fish and seafood. I'm hideously allergic to anything from the ocean that has flesh (i can eat seaweed) ... but am I missing out on some manner of vitamin that i'm not getting elsewhere?

I can't tolerate the seafood at all. One mouthful and I'm throwing up for three days. But it KEEPS on being mentioned....

What else contains the 'good stuff' that's in seafood?
