Mercury binds to selenium and inactivates its "toxic" effects.
Thankfully, fish is high in selenium (almost 1:1 to with mercury, thus canceling both out, in swordfish. Most others have ratios < 10:1).
- narutouzumaki 10y agoDoes that mean that tuna does not have much selenium? Would it be possible to mitigate the effects of a tuna rich diet with by also eating other food rich in selenium?
- stagbeetle 10y agoI don't have the ratio for tuna off-hand, but IIRC a selenium supplement is all you need to counteract a fish-heavy diet. But, yes. You can also supplement fish with higher sel:merc ratios to balance it out.
- nibstwo 10y agoTuna is a big fish. The smaller the fish, the higher the ratio of selenium to mercury. Tuna is the cut off, size wise.
