So, everyone eats tuna as part of a clean source of protein. I usually eat about 5-7 cans a week on average. Recently, I have had more and more people tell me that I am at risk for mercury poisoning. Is this true? Tuna is usually 50-75 cents a can which becomes my main source of protein so I do eat a lot of it. Please help. Thanks

I may get harped on for this but I watch Dr. Oz when I can. I fast forward through the junk and screaming over weight women. I remembered an episode on exactly this topic. here you go:
As a general rule, fish that are larger and caught when they are older have the most mercury. Salmon, which are usually caught around the age of 3, have some of the lowest levels (plus the highest levels of omega-3s) making them a great choice. Other small, young fish include herrings and sardines. Among the fish with the highest levels are tuna (especially albacore), tilefish, swordfish, king mackerel and shark. The Food and Drug Administration recommends that people eat albacore tuna once a week at most and chunk tuna no more than twice a week.

So am I at risk?
couple of cans every few days wont hurt ya...eat up! every 8-10wks just grad urself some body cleansers and youll be fine. dont stress.....been eating tuna for years!
Mercury in fish, hormones in beef and chicken, blah blah blah. We are pretty much at risk eating a fuc**** candy bar nowadays. Just eat and lift heavy!

werd! we're all gonna get cancer anyways hahahaha...just make sure later in life, eat ur tomatoes and drink OJ to counter-act it all :D haha
The FDA says 12 ounces of light/chunk tuna a week is safe for women and young kids:

They haven't set rules for hyooge bodybuilders as far as I can tell. So eat 'til your blue from the mercury. :)

Methylmercury (MeHg) is very toxic, and impacts the human nervous system when ingested. Research thus far has yielded great disparities in the amount and distribution of contaminants in different fish species. Both the benefits and dangers contained in fish appear to be dose-dependent, which has resulted in researchers in the past decade just beginning to establish a dose-response curve, based on the limited data available in this area, so that individuals can weigh the benefits against the potential harm. See, [i]Good fish/bad fish: a composite benefit-risk by dose curve.[/i] Gochfeld M, Burger J. Neurotoxicology. 2005 Aug;26(4):511-20. See also, [i]Health benefits and potential risks related to consumption of fish or fish oil.[/i] Sidhu KS. Regul Toxicol Pharmacol. 2003 Dec;38(3):336-44.
Recently, scientists attempted for the first time to create a model that can be refined in the future as more data become available on cardiovascular and neurodevelopmental risks of methylmercury (MeHg), and the health benefits of consuming fish and fish oils. Specifically, this recent study for the first time provides an integrated analysis for methylmercury (MeHg) and omega-3 FA that uses dose–response relationships on common end points and that evaluates the net effect on a species-by-species basis. [i]Quantitative approach for incorporating methylmercury risks and omega-3 fatty acid benefits in developing species-specific fish consumption advice.[/i] Ginsberg GL, et al. Environ Health Perspect. 2009 Feb;117(2):267-75. The study concluded that [b]omega-3 fatty acid benefits outweigh methylmercury (MeHg) risks for [i]some[/i] species [/b] (e.g., farmed salmon, herring, trout); however, the opposite is true for others (swordfish, shark). [b]Other species were associated with a small net benefit[/b] (e.g., flounder, [b]canned [i]light[/i] tuna[/b]) [b]or a small net risk (e.g., canned [i]white[/i] tuna[/b], halibut). These results were used to place fish into one of four meal frequency categories. See, [url]http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2649230/table/t3-ehp-117-267/[/url] which shows that swordfish, shark are best to be avoided whereas tilapia, pollack, flounder, shrimp, trout, herring, salmon can pretty much be eaten in unlimited amounts.
Here is a table from that 2009 study which analyzed the neurodevelopmental risks of methylmercury (MeHg) of eating tuna.
See, [url]http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2649230/table/t3-ehp-117-267/[/url]
As you can see from that analysis, [b]it is recommended to limit your intake of [i]canned light tuna[/i] to 12 ounces per week from a mercury standpoint, but [i]canned WHITE tuna [/i]should be limited to 6 ounces per week.[/b]
Here is an excerpt from the authors addressing this issue:
"For the cardiovascular risk group, unlimited consumption appears to be appropriate for nine species, and potentially several more. However, we downgraded canned white tuna, halibut, sea bass, and lobster to two meals per month because of concerns for neurologic effects. There is no MeHg RfD relevant for the general population, but a number of states have used a 3-fold higher target dose (0.3 μg/kg/day) given the likely differences in sensitivity for neurologic effects between early life and adults; this target dose is the same as the IRIS RfD for inorganic mercury salts. Thus, we placed species in the twice weekly category to keep MeHg exposure below the target dose for the general public to prevent neurologic effects. Tuna steak was placed in the once weekly category to limit the risk . . . which is very small at once per week. We estimated sword-fish and shark to have a substantial net risk, even at one meal per month; thus, they are in the ‘do not eat’ category." (internal citations omitted)

HAHAHAHAHHA!!!! its true haha.....all of this crap the USA pumps into its food source is all unnatural $hit. so why fight it? cant beat em, join em :) i rather be buried in a custom made oversized coffin then a standard one :) looking big n good dead! what a great way to enter the afterlife!
fu ck i hope not i just crushed 10 oz for lunch and another like 2 cans earlier this week....
I know!! I had 3 cans of tuna just yesterday!!!!!

I eat tons of tuna too. In fact I just went to Costco and bought like 50 cans of the stuff. It's an easy and healthy lunch - salad, on bread, with a fork.... But I do try to limit myself to a few times a week only.

ya man for sure. I live seriously a mile from my office so I run home pan fry some up with hot sauce, ms dash 0 cal junks and a lil mustard low cal no fat and quick 40 g of protein.
Umm guys I've had about 22 cans this week. Am I dead?

i Giggled a little, I see what you did there.
Oh, well I am eating 4 cans a day. If you see my obituary just know I was pi ssing silver
Enough of this nonsense. Anyone who's dumb enough to risk mercury poisoning for no good reason deserves what he gets.
