Do you worry about consuming too much mercury? I brought down my fish consumption after reading about this risk but I could be overblowing it. Do you have have any advice on how to deal with this?
This says the tolerable weekly intake for methylmercury is 1.6 μg per kg body weight per week. For a 200 lb man that is 80 milligrams of shark meat (p95 1835 mg/kg) or 11 lbs of sprat (p95 0.029 mg/kg) or 2.9 lbs of sardines (p95 0.112 mg/kg).
NO, for two reasons. I eat mostly salmon and sardines, and some small mackerel only. If you look up fish low in mercury there are a ton of links.
But secondly, they found that the nutrients, mainly selenium, in the fish actually help the body remove mercury through the thioredoxin system, so the worry might be exaggerated. I do not eat fish everyday as well, I eat shellfish on the off days and I fast. Oysters are really high in selenium.
Easiest step is if you eat tuna, don't eat Albacore, instead eat Skipjack.
If you can afford it then go with brands which have thorough testing (e.g. Wild Planet, Safe Catch, etc.). Granted best to go further down the food chain, but this is an easy first step to take.
