I just wanted to add something about tuna, that was on the news a couple months ago.
On the news they were saying that tuna is really not that good for you anymore because of the mercury levels in it now.
Im not sure if I would worry to much about it, or if it is a huhg deal yet, but I just wanted to bring it up just so we can be aware of it. I am gonna do a bit more reading on it when I get a chance.
