Mercury in Tuna

[Ant85]

I have been trying to stick to being healthy again and eating every 3 hours small meals. My last 6 weeks I have been very bad as I was traveliing.

 

This whole week I have been to lazy to make myself small 100g portions of lean red, or chicken for my during the day meals and during the day have substituted it with tuna.

 

So how much tuna a week is bad for you with metals like mercury. I chow about 1.5 can a day at work split in 3.

Only eat what you catch!!!

The mercury is in the ecosystem. It does not get added later. So if you catch a fresh tail slapping tuna it may already have been polluted with mercury.

Don't forget to skip out on all the GMO foods you are eating as well - Go Organic.

Yip, but i suspect the risk of mercury contamination in the open ocean is lower then the risk of the processes from ship, to handling, to machines chopping, squashing, CANNING, etc.....

 

Anyway, my chirp was just tongue and cheek!!

Have tuna for a week and then give it a break for the rest of the month.

 

My mom used to have tuna everyday and is now allergic to any fish. Too much of anything is bad.

After this week only half a can a week, shouldn't be so lazy and make some organic chicken or free range lean red meat.

My ma vra my wat soek ek op my broodjie, ek tuna mayonaise. Kekekeke

Eat from the lowest order of the food chain.

[Johan Bornman]

You can extrapolate the mercury in ocean fish by looking at how old the animal is when eaten. The older, the more mercury. Tuna live a couple of years before the Japs zap them, so they accumulate more mercury than a sardine. Stay away from those old turtles.

When does mercury contamination become dangerous or is any mercury in food dangerous as it accumulates, I think, in the body.

 

While in Mozambique we got to know two guys that started a mango plantation next to one of the bigger rivers in Central Moz. They exclusively exported through Hoedspruit to the Euro market. They then detected mercury, still within allowable parameters, in their product. It transpired that illegal gold miners in the Chimanimani Mountains in Zim used mercury to separate the gold. These guys reported it to the Moz Government who sent in troops to kill most of those involved.
