I didn't realise the tin was a factor ? I thought it was something to do with the environment and food of the fish, bigger the fish, more Mercury kinda thing. wouldn't all tinned foods carry the same problem if it was tin related? beans etc...
Don't worry about it if you're just eating tinned tuna once/twice a day (skipjack etc) or a few portions of fresh tuna per week mate. The mercury risk is overhyped and exaggerated unless fresh line/ocean caught tuna is a staple protein source in your daily diet.
That's utter nonsense mate. The mercury levels in tuna have nothing to do with the tin it's sold in. It stems from their deep water feeding habits.
I felt sure I'd seen something like crustaceans were eaten by small fish and pass their Mercury content on, small fish eaten by medium fish and so on... the Mercury content was compounded by the paying it forward element of the food chain. Hence the bigger the fish, the greater the Mercury content. Tuna greater than mackerel for example. I go through fits and starts, I was eating a tin a day with prawns for a good while at one time but thought I'd best reign it in. not had any for 6 months + bag of microwave Mexican rice, tin of tuna in olive oil, 100g prawns, plenty of sriracha sauce biuriful. one of my go to work meals for a long time. swapped it for cottage cheese and oat cakes and misery.
Don't be scared of eating tuna mate. It's fine in moderation. I eat plenty of fish but I like a bit of variety so I switch regularly betweeen tuna, mackeral, sardines, pilchards, salmon, etc. Fresh can be expensive so I stick to tinned these days and have the occasional bit of cod/haddock from the chippy. I do the same as you with the supermarket cooked rice. Quick and healthy meal. My favourite is brown basmati rice with a tin of mackeral in tomato sauce or curry sauce. Yummy ! Good source for omega 3,6,9. I don't like seafood though and I'm fairly sure I'm allergic to prawns. You're right about the feeding habits of Tuna. That's where all the mercury comes from. Nothing to do with the tin.
It’s both mate. The sea is polluted and the tins have a toxic lining that’s a good reason not to scrape the inside of it. Tap water isn’t safe IMO if you got a water analysis print out from your provider it’ll tell you what’s in it. Probably around 300 different chemical traces. I always filter my water or buy glass bottled spring water.
Imagine all the bleach that gets dumped illegally in the sewage by Thames water… 4000 illegal dumps per year!
