canned tuna and mercury
how much tuna is too much? the reason i ask is i used to eat 2 cans a day on my workout days. thats 5 days, so 10 cans a week. ive been doing this for over a year now and just recently cut back to just one can on workout days just to be safe.
so my question is-
how much tuna can u eat a day before mercury posioning becomes an issue?

supposedly its to be one can per NINE days-------ya right-----its too convenient to give it up -- f that..
open a can in the car -- down the **** with water and theres 28g protein--
sucks we lost like 7g cause they made the cans SMALLER---asses--
also the cat food type -- cheap chunk---has less mercury in it as well--

your eating mercury every time you eat tuna. To me, 21 cans a week sounds rediculous. I am surprised you dont have mercury poisining. I used to eat a lot of tuna and sushi so i had to cut down. I wouldnt go over 10 cans a week

If you're that concerned, look for "American Tuna" found at whole foods. They sell it in 4lb cans here. Its supposed to be mercury free.

if it was really that bad do you think they would sell it the way they do? fish eat fish all day and i don't see a world wide epidemic of schools dying from mercury posioning?
i don't eat as much anymore cause i am sick of it but i've easily done 21 cans a week in the past. i am not saying its not possible, i just don't buy into the whole scare aspect of it. i'm with ryod on this one!

i wouldn't worry about it bro...you've got bigger problems walking outside and breathing in the smog filled air...either way you look at it, your going to die from something..no sense in worrying too much about it...Look at it this way... roughly 180 million cans of yellowfin tuna are sold in the U.S. each year...how many cases of Mercury poisoning do you hear about...i think your ok

Its not as much about mercury poisoning deaths, its more about the small changes in your body due to higher levels of mercury. Its a lot like the whole biphenol-A (BPA) stuff in plastic. Its not causing deaths or poisoning but it causes hormonal changes over time, or so they speculate.

After all, you are trying to be healthy, mercury isn't something that you want to knowingly ingest. Buy the mercury free version if you are going to eat it that much IMO.

The American Tuna brand is supposedly tested by Berkley? I want to say and the fish they test are found to have zero to very trace amounts which in turn means that one can of tuna likely has zero mercury but could have very very minute amounts.

lowest mercury content from fish is cold water sources such as salmon.
also farm raised...which costs more!

this reminds me of the salmonella from eggs debait...possible but extremely unlikely.

We asked him the tuna question and he pretty much said not to worry about it. I can elaborate, but that's pretty much the bottom line. And he knows his stuff when it comes to mercury (look into him and you'll figure it out).

Even the cheap **** at the store is a little over $1 per can. So you figure $1.15 per can, then if you are eating 3 cans a day, that is 24.15 per week, and 96.60 monthly.
That is a big chunk of my monthly grocery bill. Tuna is not cheap IMO.

"If it's not one thing, it's another. A recent Finnish study found that eating mercury-filled fish might undo any heart-health benefit of the omega-3 fatty acids it provides. Scientists tracked the diets of 1,871 men for 14 years and found that those who ate the most fish had higher mercury levels and were 60 to 70 percent more likely to develop heart disease. Mercury impairs arterial flexibility. To avoid it, reel in the right kind of fish. "Salmon are low in mercury because they eat mainly plankton, not other fish," says study author Jyrki Virtanen, Ph.D., R.D. Cod and whitefish are also light in the heavy metal."
I can not even imagine eating 5 cans a week. I rarely eat it mainly because chicken is cheaper and beef tastes better.

I still think it's horse **** how they downsized the cans though. Starkist solid white albacore (canned in water) for me. I used to eat the low sodium bumblebee albacore, but it is more expensive, and also very dry once the water is drained.
