What this means for you

A Detox Score of 48 places canned tuna in the Moderate band. The persistence rating is the standout concern here — these compounds linger in the body and environment for years. Larger tuna accumulate methylmercury, which builds up in the body. Choosing smaller 'light' tuna or sardines keeps the omega-3s with far less mercury.
