Thanks for all the great advice, responses and concerns and from so many of my 3FC "heros" too!
On mercury, I try to be careful with that. I eat mostly smaller fish lower down the food chain where this is likely to be less of a problem (e.g. sardines, anchovies, wild salmon).
The stuff I limit, but still eat occassionally and store, are albacore tuna, some of the bigger mackeral and (fresh, not canned 'cos it's real hard to find) swordfish.
To be honest, though, I'm willing to take the risk of mercury, PCBs etc. given the other health benefits (e.g. Omega 3s, lean protein etc.). But if I start going mad (sorry...even more mad), you'll know why.
However, if I were a woman looking to have a child some day, I am not at all sure I would play this game given the potential risks to infants. And my very young kids won't be getting this diet either as per mom's instructions (but a little oily fish won't harm them every now and again).
That being said, I enjoyed 4 cans today with some 'fresh' fish...Bar Harbor canned kippers, Polar canned Jumbo Lump Crab, a pouch of Good News Tuna Company smoked Albacore tuna and some fresh smoked salmon with 10 anchovies (I buy raw anchovies salted in a 2.2lb can, fillet them and soak them to reduce the sodium). All eaten with a hearty salad as is the norm. And oats for breakfast.
Arctic Mama, sardines are my go-to too. I currently have 30 cans at home and 20 cans at the office. Yum. (I've started that inventory Larry H!).
Krampus, I also eat kimchi (daily) and love it. I would stock more of it but I eat it too fast so a stash never builds. I should learn to make it but I'm too lazy so just buy Lucky Food's kimchi instead. It's wonderful. But does smell of smelly feet (don't say that to a Korean!). I guess those extra fridges are an investment then!
