Pablo Hernández Baeza: Canned Tuna Threatens Footballers' Brain Health

Natural medicine specialist Pablo Hernández Baeza warns that canned tuna’s mercury levels can harm footballers’ brain health and cognitive performance. High mercury content in tuna can lead to long‑term memory loss and reduced concentration.

Players rely heavily on mental sharpness during intensive training and matches. Hernández advises limiting canned tuna to one can per week and opting for omega‑3‑rich fish alternatives.

He also recommends regular laboratory testing to monitor mercury exposure.
