HONOLULU (07 November 2024) Recent media reports are wrongfully perpetuating the claims that eating tuna has negative health effects because of mercury.

What the media reports fail to disclose is the fact that tuna also contains selenium, a mineral with many health benefits that plays a key role in the body’s metabolism. Selenium is an antioxidant that protects cells from damage caused by aging, pollution and lifestyle choices.

Ocean fish, especially tuna, provide a rich source of nutrients essential for health, such as omega-3 fatty acids, selenium and vitamins. Selenium, in particular, is known to counteract mercury toxicity, making these fish safe to consume.

Dr. John Kaneko, a Seafood Safety Specialist in Honolulu, HI, penned an article in Spring 2024 to address this important topic called, “Seeing Through the Haze: Understanding Tuna, Mercury and Health.” He notes “it is the ratio of selenium to mercury that determines if a food is likely to promote or protect against mercury’s toxic effects.” Kaneko cites several recent studies, including a 2023 issue of Neurotoxicology, that emphasizes maternal fish consumption during pregnancy positively impacts child neurodevelopment, with benefits outweighing any mercury concerns.

There has never been an incident of mercury poisoning linked to tuna consumption in the public. The well-documented health benefits of eating ocean fish, which include improved heart health and cognitive function, support regular seafood consumption as part of a balanced diet.

We encourage consumers to continue enjoying seafood and remind the public to consider the evidence-based nutritional and health benefits of tuna and other ocean fish. Let’s focus on encouraging healthier diets and not allow myths to deter us from one of nature’s healthiest food sources.
