I've read that the white albacore tuna is significantly higher in
mercury than the light. I'm not sure why, but I like the light
anyway. I buy either Bumble Bee or Chicken of the Sea and haven't
noticed a difference between the two. I like canned tuna a lot.

The albacore comes from a bigger fish -- IOW, the fish had more time to
absorb mercury from the environment.
