7. Tuna Tremors
It may shock you to learn that your innocent tuna sandwich could potentially induce neurological damage. Larger tuna species like bluefin and bigeye accumulate high mercury levels due to their place atop the food chain.
When humans ingest too much mercury from frequent tuna consumption, the effects can be quite alarming – lack of coordination, vision problems, impaired speech, muscle weakness, and tremors.
In fact, the infamous “mad hatter” derived its name from hat-makers exposed to mercury who developed shaking symptoms. While an occasional tuna meal is fine, frequent indulgence poses the risk of mercury poisoning for tuna lovers.
