Efectos del consumo del beta-glucano de la avena sobre el colesterol sanguíneo: una revisión

Aránzazu Aparicio Vizuete, Rosa María Ortega Anta

Resumen


Las cifras sanguíneas de colesterol total y de lipoproteínas de baja densidad (LDL) elevadas se consideran como uno de los más importantes factores de riesgo de enfermedad coronaria. La avena es un cereal rico en proteínas, lípidos, vitaminas, minerales y fibra soluble, entre las que se incluye el beta-glucano. Debido a las características físico-químicas del beta-glucano, se ha propuesto que la avena pudiera contribuir a disminuir las cifras de colesterol sanguíneo, así como a controlar la glucosa plasmática postprandial y la respuesta insulínica. Numerosos estudios señalan que el consumo de un mínimo de 3 g/día de beta-glucano de forma regular, como parte de una dieta con un bajo contenido en grasa saturada y colesterol, puede contribuir a disminuir el riesgo de enfermedad coronaria, tal y como han aprobado diversas agencias reguladoras, como la Food and Drug Administration de Estados Unidos o la Agencia Europea de Seguridad Alimentaria.
