On eating more fish: How worried should I be about mercury poisoning? Is it worthwhile to carefully select fish for low mercury content?

For instance, one guy on /r/fitness reports that 2 cans of chunk light tuna a day gave him mercury poisoning; while you're not recommending that much fish, I'd expect that health detriments appear long before full-blown mercury poisoning.

(I'm not expecting you in particular to tell me this, I just want to know if someone on LW has already done this research.)

For pregnant women, these days they're recommending oily, low-mercury fish like salmon, herring, and sardines. Chart

I would recommend against eating canned food to limit your exposure to Bisphenol A.

I would also not eat tuna every single day for such an extended period of time!

I can't access the actual article, though the abstract certainly indicates that BPA is harmful.

Does the article include evidence showing that eating canned food is a significant exposure risk?

What kinds of cans specifically? what kinds of foods?

Are there other significant sources of BPA?

Here's a randomized trial from JAMA showing more than 1000% increase in urinary BPA after consuming canned soup: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3367259/

BPA used to be in a lot of plastics, but I think it has been phased out. Perhaps someone else can confirm or refute that.

Another source is transdermally through handling receipts. I've heard of at least one health conscious workplace giving their cashiers wooden tongs to handle the receipts. Best practice would probably be to email them instead. Saves paper too.

Oh yeah, salmon is easily the best for health benefits AFAIK. I should include this in the post.

Must be wild salmon, not farmed salmon. The difference in Omega 3/6 ratio is immense.

Is tuna all right if I have a hard time getting salmon? I can get tuna salad at the grocery store or tuna sandwiches for lunch comparatively easily, but salmon can be expensive here.

I was going to recommend kipper, but this says it's not that much better than tuna. It's still better, at least in terms of mercury.

This PDF says canned sardines have 1 gram EPA+DHA per 100g, whereas herring has slightly more and tuna is all over the place.

Not very good evidence for kipper vs. sardines (I buy kipper just because I can't stand sardines, though I'll look out for salmon now that it's been mentioned), but either looks to be preferable to tuna.

Tuna has among the highest mercury content per serving IIRC.

The health benefits of fish outweight the health detriments of mercury until way beyond the level of consumption you're likely to get to.

Just eat fish.
