I thought I had found the perfect food/protein source in white albacore tuna a few yrs ago. Packed in water, for only 50 cals hit got 11 grams of good quality protein. Lots omega 3's, almost no saturated fat. As an aside, I loved those big chunks of white lean goodness ...it satisfied me cravings

.
I ate 2 to 4 cans per day almost every day, for 6-7 months. Add some greens, steamed veggies. happy, happy. At that time I kind of heard about mercury/heavy metals in tuna, but didn't look any further (how much can there be??

)
I ate 400-500 cans over 7 months! Can't recall what prompted me to research it any further, probabl another news report. I was shocked



at levels of methylmercury/heavy metal I was consuming. The perfect protein/food source made almost worthless by ocean polluters.
Compounded when I also learned that methylmercury is deposited in body tissue/organs for yrs, if not decades and may never come out. That day I threw out rest of my pantry of tuna cans, and never took in another forkfull. Stopped eating all tuna, all farm-raised fish, don't care for much fresh-water fish but will eat an occasional wild cod.
Now my protein sources are canned chunk chicken breast, occasional canned wild alaskan salmon (who can prove it's really alaska though

), and a pizza once or twice / month. Nuts. Low fat cheese.
Albacore tuna is perfect protein source/ perfect food (better than eggs) but for the heavy metal contamination.
Just wanted to share this true story, and this is how I came to looking into fish/seafood a bit further.
