Nuestro cuerpo está constituido de células. Dentro de éstas ocurren constantemente reacciones químicas, que se conocen colectivamente como metabolismo. Estas reacciones son necesarias para la vida, pero algunas veces crean radicales libres. Los radicales libres son moléculas altamente reactivas que pueden iniciar reacciones dañinas en cadena en nuestras células. Esto se conoce como estrés oxidativo. Diversas investigaciones relacionan el estrés oxidativo con muchas enfermedades: artritis, enfermedades de los pulmones (como enfisema), enfermedades del corazón, enfermedad cerebro vascular, ulceras, hipertensión, Parkinson y Altzheimer, distrofia muscular y otras. El estrés oxidativo también contribuye al proceso normal de envejecimiento. This 3-page fact sheet is the Spanish language version of Facts about Antioxidants, written by Kaitlin G.

Facts about Antioxidants
Our bodies are made up of cells. Chemical reactions necessary for life are constantly occurring inside our cells, and sometimes they create free radicals — highly reactive molecules that can initiate damaging chain reactions known as oxidative stress.
Antioxidants can inactivate free radicals and protect our cells from oxidative stress and the damage it causes. Antioxidants also can help our immune system defend against bacteria, fungi, viruses, and some cancers. The body produces some of its own antioxidants, but eating a plant-based diet increases the level of antioxidants in our bodies. This 3-page fact sheet was written by Kaitlin G. Clark and Wendy J. Dahl, and published by the UF Department of Food Science and Human Nutrition, February 2014.
