Is Too Much Tuna Bad for Youの全体像を丁寧に掘り下げてご紹介します。

Not all tuna is created equal, and this is where it gets fun. Canned light tuna is usually skipjack—smaller, younger, and with about one-third the mercury of albacore.

Albacore, or “white” tuna, is the big daddy of the can, and yes, it’s richer in taste and omega-3s. But because it’s larger and lives longer, it accumulates more mercury. It’s a classic trade-off: better flavor vs. lower risk.
