Loving Your Tuna!
The skinny on Tuna is real simple; eat it in moderation and if you are going to eat it, you should be certain it is sustainable. Know how and where your Tuna is caught!
I love the Eco Safe Tuna website; they provide good information on industry, buying tuna and tuna fishing practices.
You can also find information at National Fisheries Institute, about mercury levels of Tuna.
