Not sure which forum to post this in, but move it if you must :)

my family buys Cloverleaf canned tuna on sale at Walmart. Like, 40-60 cans when on sale.

I have a brother that ignores his health and binge eats like a fool for pleasure. For instance, 8-9 cans of Coke per DAY/Night....daily take out fast food (Mcds/Subway/Mr.Sub/Wendys, etc)....his diabetes probably thru the roof, eats a bowl of ice cream pretty much every day, chocolate bars /pop corn/ you name it.. He is not a kid, he will be 65 in August.
Back to the tuna .
Over one year now, he started eating canned tuna sandwiches about 2-3 times a week. Then went to eating it everyday . Sometimes later at night. So sometimes twice per day.
85 grams Skipjack light tuna in olive oil.
I keep reading it is bad to eat can tuna more then twice per week. That all seafood, including tuna, has traces of mercury. Then I read some cans tested had wild fluctuations in testing of mercury from can to can....some excessive, some just a little. And over time, the mercury builds up in our bodies, we get issues with mercury poisoning.
Maybe the worst is neurological symptoms , such as dementia, hands shaking, speech slurring.
Which I have noticed in my brother.
But that can also be due to high blood glucose / diabetes.


-- Have you ever consumed too much canned tuna and had health issues?
if so, was it reversible? https://www.consumerreports.org/hea...ou-be-about-mercury-in-your-tuna-a5041903086/
 
A blood test will tell if he has dangerous levels of Mercury in his blood. He'd have to let his MD know to test for it. I was concerned with Lead and Mercury in my blood from years of painting. Testing showed I had no problems with it. I'd tell him to get tested since you're concerned.

This here.

Stop worrying over a phantom fear at this point fueled by speculation.

Albacore has more Mercury than other types of tuna
 
Canned sardines in olive oil are your healthiest bet. Small cold water fish have the lowest mercury load. Mackerel is also good.
I don't care for sardines personally and prefer canned kipper snacks. Really just herring.

Tuna are at the top of the food chain and serve as bioaccumulators for mercury and other heavy metals. Smaller tuna generally have less mercury.

I have heard of mercury poisoning through seafood. Apparent a guy in Taiwan who got a big lottery jackpot and could afford shark fin every day. The fins were really high in mercury.

As long as it's the Atlantic Mackerel. Others such as King Mackerel can be high in mercury.

As for canned tuna, I've switched to canned salmon. Some people don't like the taste. For me, I can't really tell much difference. When I make salad from a 6 oz. can, it'll last me for 4 lunches.

Based on what you wrote above, mercury may be the least of his problems. :)
 
Canned alaskan salmon has the advantage of being cheap and also really high in Omega-3 without the mercury risk...if you can get over the bones (I remove the large ones) and skin. I eat a can a week (larger than tuna cans) and then one or two cans of albacore tuna (skip the oil, and add your own EVOO on salad.)

It doesn't really sound like your brother is on a track to be concerned about his health. I wouldn't worry about it. All the carbs from those sandwiches (and his other bad habits) are going to get him to the diabetes and heart disease finish line far faster than any concerns from mercury.
 
8 cans of coke per day? I'm surprised he has any teeth to even chew the tuna sandwich.

Anyways, tuna sandwiches are way better than fast food. Tell him to keep it up.

Cadmium and inorganic arsenic can be an issue with certain sardines. Like those from the Baltics.
