If you are male.

i think i may be eating way too much. Fresh Salmon 3/4 times a week. and Tinned Tuna about 4 times a week. With the occasional Cod now and again.

Its only because i saw warning about Tuna but then read it only affects females.
And there are guidelines about having oily fish twice a week

Isn't there something about high levels of mercury in tuna?

I doubt it. The Japanese eat the most fish per capita and also have the highest life expectancy of any major nation.

No, its very good for you although some fish is high in Mercury

I eat Cod 3 times a week and I feel great. Canned tuna can be high in Mercury as anderson said, but other than that, you can only benefit from eating fish.

I eat fish daily, tuna daily, it's done me no harm

Been on quite a tuna in oil binge lately, so much nicer than brine. The thing that gets me is the no drain tuna costs more than the one filled with oil. Someone explain how they charge more for less, I'd rather have the no drain with a just a touch of oil on it and just tuck in - pouring all that oil away is such a waste but I can't afford to waste money, so.

Some fish have a lot of mercury in them while others have none, luck of the draw on that side of things - depends where and what that particular fish has been eating, It's not uniform across all of them.

Very high in protein, great for muscle growth.

I don't eat fish... at all...

However certain fish is supposed to limited (or avoided altogether) in pregnancy. Tuna is to be limited and shark / swordfish / marlin is to be avoided altogether.

Sardines on toast with Worcestershire sauce, mmmm.
I have this once or twice a week.

I like tinned tuna, but didn't know this about mercury,

I won't ever knowingly consume farmed fish, whether it be Scottish salmon, or sea bass or tilapia from the Mekong. If it's not line-caught, wild, trawled from deep waters I don't want to know. Unfortunately, everything that can be farmed is now farmed and it's difficult to find the wild alternative.

I eat canned tuna, mackerel, sardine and pilchard but canned food isn't without its chemical concerns either.

Yeah best to eat wild Alaskan fish. Then there's no worry of mercury.

I mainly eat fish, chicken, brown rice, vegetables and salad. If that's not healthy then I don't know what is.

What, deep fried chicken, fish and chips, vegetables roasted in butter and oil and a slice of cucumber? Creamy brown rice pudding for afters?

I'd imagine it's a more advanced process to can the tuna without oil or water and have it not spoil.

Most fish are good for you. However avoid the fish that tend to be at the top of the food chain as they tend to have mercury in unhealthy quantities. Found this useful guide whilst trawling around the internet:

http://www.nrdc.org/health/effects/mercury/guide.asp

I know we are supposed to avoid fish with high concentrations of mercury, but what actually are the health risks of eating fish high in mercury? How dangerous is it? Have people died directly as a result? Or do the potential benefits outweigh the potential risks?

They still have oil though, no drain tuna in sunflower oil, in brine and mineral water, just not a huge amount you have to empty out. I like to think your theory is correct but they usually aren't as logical as that.

Probably think they can get a few more pence out of the gimmick from people who don't like to waste food, however I don't like to waste an extra quid on less, so.

There's bound to be by-products in some food such as the brine or vinegar in jars of pickles, pickled onions, red peppers etc.

Do people reuse the liquid from jars of red peppers?

(I must admit, I do add pickled onion liquid into malt vinegar for use on fish & chips )

Bought a tin of no drain tuna chunks and they are a little too sharp for me, taste more like the brine variety than sunflower oil. Also bought three stacks of the normal stuff so I'm happy, tuna in oil is very tasty.

I like tinned salmon and tuna but they don't like me for some reason so i cannot eat them. I eat fresh salmon about 3 times a week, prawns as well. Going to try trout next as i have never had it before.

I suppose too much of anything can be bad for you, but you'd have to eat a lot of fish, not sure many people are anywhere near 'too much' though.

It might not be because of the fish. They also eat loads of fruit and vegetables as well.

I agree with this. Doing too much of anything that's good for you will end up being bad for you.

Well, I presume you are paying for that oil you are pouring away, because it forms part of the weight of the product.

Have you tried comparing the cost of the tuna you actually get to eat in both cases?
