Sinc eI have started the zone I have been eating a lot of tuna. 1 can per day usually. I have been buying the Kirkland branded albacore (blue can) in an 8 pack I think. It is white and dry. Now, I just picked up a 16 pack of Chicken of the sea at costco (green can) for half the cost! This tuna is much more loosely packed and is darker in color.

What is the difference? Am I ok, assuming I like the taste, with getting this cheaper tuna?

Nick

"Light" tuna (which is darker) tastes and smells fishier than "white" tuna.

My favorite is StarKist Gourmet Choice solid light tuna in Olive Oil. It's the only kind I can find in 'Olive Oil' at my local grocery store. It also has like 1/3 of the sodium the other ones packed in water have. It's like $1.29/can vs 60-70 cents for ones packed in water. There's just not enough olive oil though, so after I take a bite or two, I pour a bunch more olive oil in :-) Tuna packed in water is pretty dry and I have a hard time choking it down.

I think the albacore supposedly has a lot more mercury.

I'm not extremely well-versed on the mercury issue, so while we're on the subject, do you guys worry about this?

mercury concentration increases the higher up the food chain you go.
try and vary your intake with some smaller fish as well, this should cut down any risks, and stop you getting bored...

Canned light tuna has been shown to be significantly lower in mercury than albacore. Tom C. is correct. The higher up the food chain you eat, the higher the concentration of mercury. Swordfish, king mackeral, shark, large tuna, etc. are the worst. Check out this fact sheet from the Monterrey Bay Aquarium http://www.mbayaq.org/cr/cr_seafoodwatch/content/media/MBA_SeafoodWatch_HealthFa ctSheet.pdf. If its of concern to you, they also have lots of information on which fish are the best to eat in terms of environmental impact. If you're trying to increase Omega-3's in your diet, salmon (especially wild) and sardines are significantly better sources than tuna, and with lower mercury concentrations as well. Also, if you're trying to reduce your environmental foot-print, both are abundant and sustainably harvested.

Thanks Tom & Scott. I really like wild caught salmon and tuna, so am interested in the subject.

I have heard men should limit tuna to 2 - 3 servings per week, women 1 - 2.

I suppose I should go get some facts for this...but I have heard of ppl taking supplements specifically to counteract eating 1 can of tuna daily.

I like tuna w/ salsa and peppers :-)

2-3 servings per week? Holy Carp (heh heh heh, get it)!!! I eat 1 can per day as a general rule. Its the easiest CF Lunch for me to make. I switch over to the light tuna mainly because of the cost and my wife likes this stuff better than the albacore anyways. The albacore tends to be drier than the light tuna.

Canned tuna has loads of mercury in it. I've read that mercury never really leaves your system; it just hangs around until you build up a toxic level.

Obviously it would take a whole load of tuna cans to cause significant detriments, but staying away from more than a can or two a week is a good idea in my opinion.
