Let's Talk Tuna & Mercury.........

All people have the right to know the facts about the amount of mercury in the tuna they consume.Should we be concerned? So how much tuna can a person eat without getting mercury poisoning? It really does depend on the person.

Heavy Metals: Mercury, like zinc, iron and lead are heavy metals. But mercury is the only one of these 4 heavy metals that has no useful function in the body. The only thing mercury does in the body is to negatively affect the brain and kidneys.

What happens to the tuna you eat?? Well, first the tuna is absorbed by the small intestine and then it's shipped over to the liver. After that the mercury either enters the bile for discharge or the blood. If it reaches the blood from there it can enter the brain or kidneys, not good. However if the dosage of mercury is not excessive and doesn't overwhelm the system the kidneys will do their job. But if it finds to the brain via the blood brain barrier it gets stored. That storage option is what leads to mercury damage to the brain and kidneys.

So how much mercury is in tuna?

As a general rule canned tuna has less mercury than a tuna steak and chunk light has less (Boo!) than chunk white tuna.
Of course it also depends in which ocean the tuna was caught. An Atlantic tuna would be my first choice. But it's hard to find that information and will become even harder when TPP allows food products not to be labeled with their place of origin. Trying to eat healthy just gets harder. Also there is a lot of contradictory information floating around about mercury in tuna.

The CDC states that a person can chronically (all 365 days) ingest .0003mg/kg of mercury per day with "no observed adverse effect." but that doesn't mean it's healthy in my book.

I have never eaten much seafood as I have an iodine intolerance but I do eat tuna on occasion. I suppose if I was eating seafood on a regular basis I would need to rethink the amount of tuna I would eat each week.

We haven't bought tuna in years. We were debating this very topic on some other thread here recently, can't remember which though.

We're eating a lot of sardines though, from the northern Atlantic only.

It's a tragedy we've done this to our planet sad2.gif

I won't touch anything from the Pacific after Fukushima. Wont touch anything from the Baltic sea either.
From my understanding, mercury is like radiation, in that any amount is too much.

Oh I love salmon! The wild ones here have white, not pink meat. Omg smoked salmon nomnomnom.

But then we have another set of toxins to worry about here. Dioxin levels in fish such as herring are so high that according to EU regulations Finland can't export it, but we can eat it ourselves. Not too often though. Oh well, JR doesn't like herring anyway tissueguy.gif

Fish from the mid 1800s,have been preserved at the museum of natural history in NYC. They tested them back in the 2000s for mercury levels, and 150 years ago, the mercury levels were the same as they are today.
So, it's the nature of the fish to have such mercury levels.
That being said, no one should eat tuna at all. Not blue find not yellow tail, not albacore. We are selfishly fishing thrm all into extinction.

So it all comes down to "what to eat" when everything on Earth has been poisoned? Things have spiraled out of control.

I would be concerned about eating any fish or seafood caught in the Northern Pacific.

I remember seeing a documentary about mercury poisoning as a kid, they were showing entire villages of native Americans in northern Canada that suffered from mercury poisoning.

The symptoms were horrific, scared the daylights out of me.
