Study Says Too Much Mercury In Tuna, Alternatives?

**El Jugo Buen0** · 09-11-2006, 01:14 AM

This really really sucks the big monkey c*ck because, tuna is the really only inexpensive food high in protein low in fat. Do any of you guys know of brands or stores that sell low mercury tuna or are there any other alternatives? Chicken is too expensive to have 4 times a day.

if you are going to eat tune, your best bet is to buy flaked light tuna, making sure it's skipjack tuna. Skipjack is a smaller species of tuna, meaning less bio-accumulation of toxic metals. Canned salmon is your best bet for canned fish, but there is a lot of fat in these (though it's the best type of fat).

but i think you will need to eat insane amount of tuna to get mercury poisioning

not really. the recommendation is 1 to 2 cans a week now. mercury accumulation in the body is nearly impossible to notice until signs of poisoning occur.

just as an example, i recommended an older, wealthy friend to oasis for hrt. his doc did a full physical, $2500 out of pocket. his mercury levels were 650% higher than they should be and he hasnt had tuna in years. the doc was extremely concerned because they couldnt get the number to lower after various tests and procedures (system flushing and such).

im interested in this topic as well. i eat about 2 cans of tuna a day, and i also heard that eating more than 1-2 cans a week can do harm to your body.

**stayinstacked** · 09-11-2006, 09:45 PM

Sounds like a bunch of bullshit to me, I've eaten as many as 35 cans of tuna in 1 week b4, I guess I'm really ****ed. What the hell doesn't give you cancer or get you sick these days? I'm going to go eat a can right now

What does MeHg do in the human brain? Monomethylmercury (MeHg) is an estimated 100 to 1000 times more toxic (than elemental mercury) to humans. In fact, MeHg seems to specifically target the advanced Central Nervous System (CNS). Until recently, this was a mystery, as the CNS enjoys the protection of the Blood Brain Barrier (BBB). The BBB consists of tightly packed endothelial cells that line the walls of the blood capillaries in the CNS. The key to understanding why MeHg is so toxic is to see that structural similarities in biochemical reactions can lead to active transport of toxins. In the case organisms with a highly advanced CNS, like humans, this active transport can lead a brain accumulation of MeHg.

As mentioned before, most of our exposure to MeHg comes from bioaccumulations in fish. When we eat contaminated fish, this ingested MeHg easily passes through the intestines and into the bloodstream. The pathway of MeHg from the bloodstream to the brain is complicated, and we think it is easiest to understand the pathway through a list of the various processes involved:

MeHg in blood plasma can combine with cysteine, forming a compound that is structurally similar to the amino acid methionine

This MeHg-cysteine compound is actively transported into the endothelial cells in the BBB, on the methionine carrier.

A high level of reduced glutathione is maintained in the endothelial cells, and the MeHg switches from a cysteine carrier to a glutathione carrier.

MeHg-glutathione is actively transported out of the endothelial cells and into the brain.

In the brain, the hydrolysis of MeHg-glutathione generates MeHg-cysteine.

This MeHg-cysteine can now enter nerve cells in the brain, where it accumulates. The reason why it accumulates is unknown, but it is known that reduced glutathione levels are low in some neurons. It is thought that this low level of reduced glutathione might allow MeHg-cysteine to remain in the cells, unlike in the endothelial cells.

Furthermore, since MeHg-cysteine is structurally similar to the amino acid methionine, it may interfere with protein synthesis in nerve cells. This is especially likely, since methionine is always the first amino acid involved with protein synthesis. However, the exact process is not yet fully understood.

Does anyone want to **** w heavy metals? not i

Screw what the doctors have to say. According to him, my test levels are entirely too high. pfffttt

The day I piss and it looks like liquid mercury... is the day I'll consider my tuna consumption.

**russia dog** · 09-12-2006, 11:33 AM

i thought it's over rated..

ive been eating 10 cans of tuna per day for almost a year now.... and **** i dont feeel shit nor my mercury inceases on my the blood test

**InsaneInTheMembrane** · 09-12-2006, 12:52 PM

oh well,

good thing I hate tuna

don't go anywhere near that stuff

anywayz, for all you tuna guzzlers, you have been WARNED

**audis4** · 09-12-2006, 12:58 PM

fvck studies, I never listen/read those things.
If I die, I'll blame the mercury from the tuna and the splenda in my oats.

**AleX-69** · 09-12-2006, 01:21 PM

the smaller the fish the less mecury it contains -- absoulte and percentage wise.

Audis, you don't read studies? why not? Where do you think causal relationships are demonstrated, new ideas tested. Where do you get your knowledge then?

Bro, if I read every study that came out about the foods I ate and believed them, I'd be a fvckin wreck!
Sure, I don't go overboard with things like splenda/tuna etc. it's about keeping shit in moderation.
There are bigger things in life to be concerned about.......

Yupp I did

but I found conflicting info, one study claiming vitamin c did nothing at all to remove heavy metalls from the body, and never bothered to dig more on it

http://www.ncbi.nlm.nih.gov/entrez/q...=pubmed_docsum

CONCLUSION: One must conclude that the palliative effect, if any, of GSH, vitamin C, or lipoic acid for treatment of mercury toxicity due to mercury vapor exposure does not involve mercury mobilization from the brain and kidney.

edit..acctualy two studies

http://www.ncbi.nlm.nih.gov/entrez/q...=pubmed_DocSum

We administered intravenous infusions of 500 ml lactated Ringer's solution with and without addition of 750 mg of ascorbic acid/kg body weight, up to 60 g ascorbic acid. Average mercury excretion during the 24 h after infusion of ascorbic acid was 4.0 +/- 0.5 micrograms (mean +/- SEM), which was not significantly more than after infusion of Ringer's solution alone (3.7 +/- 0.5 micrograms). Lead excretion was similarly unaffected.

**Kärnfysikern** · 09-13-2006, 07:33 AM

It might still be usefull(Damn you I was studying and now you got me digging a bit

) by rendering heavy metalls less bioactive

http://www.ncbi.nlm.nih.gov/entrez/q...t_uids=6940480

Ascorbic acid has been found to interact with several elements in such a manner as to render them less available for animals. This property of the vitamin has a negative effect on the animals fed a copper-deficient diet, but a positive effect on those fed toxic levels of copper, selenium, vanadium, and cobalt. The effect of ascorbic acid in alleviating cadmium toxicity has been attributed to the effect of the vitamin on iron metabolism, since ferrous iron will also alleviate cadmium toxicity in the Japanese quail. The results of studies reported here indicate that iron will alleviate lead toxicity but ascorbic acid is ineffective. Ascorbic acid will alleviate mercury toxicity, but iron exacerbates this condition. For these two elements, the effects of iron and ascorbic acid are independent of each other.

Sorry bud.

Long time not talk.

mercury in tuna, splenda, aspartame, you name it. I'd be more worried about the 1.5 million + unknown man-made carcinogens we breath in a a daily basis. But, then if I worried about all of this shit I probably be living in a bubble.

Eat the tuna, drink the diet drinks, and hit up the splenda. Its all hype.

dido....people get too caught up in the small things.

**timtim** · 09-15-2006, 05:31 PM

there is a huge difference between the probable but not proven effects of asparteme and the known, proven, researched effects of mercury. true most may not suffer from mercury poisoning in their lifetime but it does happen. tuna has been found to have a ton of it, and everyone has been warned. its a personal choice to ignore the research but dont minimize the reality of the situation. its like smoking and cancer. it kills some but not everyone. do we minimize the reality that cigarettes are terrible because not everyone gets cancer?

do research on mercury poisoning, its not that rare. i did and it was pretty eye opening/scary.

**MR_T** · 05-04-2008, 06:15 PM

bringing up an old post to find out if anybody found a solution? my diet would work out a lot better if I could step up tuna to more than 2X a week

**novastepp** · 05-04-2008, 06:29 PM

i know light tuna doesn't have as much mercury as say albacore tuna. the cheap stuff at walmart or wherever should be ok. i don't know of a single instance where someone got sick from the lite stuff. but be careful if you stray away from the chunk lite.

like svartur said you'd have to eat a lot of tuna before you'd feel any mercury in your body none the less its kind of like the poppy seed theory that if you eat enough it comes up in a blood test when proven that you'd need to eat about a pound or seeds for it to show up slightly.

**Coop77** · 05-04-2008, 09:49 PM

I think the health benefits of canned tuna and all fish way outweigh the mercury risk. I don't know anyone that's actually gotten sick from mercury in fish.

**MR_T** · 05-05-2008, 12:12 AM

so i guess I should rephrase my question, if I get the lite tuna.. how much would be safe, I am at 2X a week and I would really like to bump it up because its cheap and gets the job done, I have always been told tuna was off limits more than 2X a week

Thanks guys

**novastepp** · 05-05-2008, 08:05 AM

bump it up. 2x a day would even be safe man.

the same people who feed you this tuna poison crap are the same people that say we need to eat 60g of protein a day? and you believe them???FDA= Fukin Dumb Asses
