Los micronutrientes son componentes minoritarios pero esenciales de nuestra dieta. Actualmente existe una creencia en los países occidentales desarrollada y apoyada por evidencias científicas que supone que el consumo de ciertos micronutrientes previene importantes problemas de salud. Se alude a un fenómeno conocido como estrés oxidativo, que es causa de envejecimiento y degeneración celular y que puede ser contrarrestado mediante el consumo regular de micronutrientes antioxidantes. En concreto, entre el amplio colectivo de personas que practican deporte, esta creencia está muy extendida y arraigada y las ventas de determinados productos se han disparado en las dos últimas décadas, suponiendo un gran mercado de consumo para las empresas del sector; de hecho es frecuente encontrar en la mayoría de los centros deportivos y gimnasios de nuestras ciudades algún estante en el que se exhiben para su venta complementos nutricionales que contienen productos antioxidantes que prometen mejorar la salud y el rendimiento… El presente trabajo pretende responder a la cuestión acerca de la necesidad o conveniencia de emplear suplementos nutricionales antioxidantes para mejorar la salud de las personas que practican deporte de forma regular.
