The Claim
Seafood consumption in healthy adults from Galicia, Spain, is positively associated with elevated serum concentrations of selenium as well as toxic elements arsenic and mercury, indicating concurrent exposure to both a nutritional nutrient and environmental toxins from the same dietary source.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People in Galicia, Spain, who eat more seafood have higher levels of selenium—a beneficial nutrient—as well as higher levels of toxic elements like arsenic and mercury in their blood, because seafood contains both.
See the scientific wording
Seafood consumption is positively associated with both serum selenium and toxic elements arsenic and mercury in healthy adults from Galicia, Spain, indicating that the same dietary source contributes to both nutritional benefit and potential toxic exposure.
What the research says
1 studyEating seafood increases both good selenium and bad toxins like mercury and arsenic in the blood — so it’s a double-edged sword: healthy but potentially risky too.
