Soya - Overview

Definición:

La semilla de soya ha constituido una parte de la dieta de los seres humanos por casi 5.000 años y a diferencia de la mayoría de los alimentos provenientes de las plantas, la semilla de soya es rica en proteínas y se considera equivalente a los alimentos provenientes de animales en términos de calidad de la proteína que contiene.

Funciones:

La soya (soja) en la dieta puede reducir los niveles de colesterol y es una conclusión apoyada por muchos estudios científicos. De hecho, la Administración de Drogas y Alimentos (FDA, por sus siglas en inglés) de los Estados Unidos reconoció que 25 gramos por día de proteína de soya, como parte de una dieta baja en grasas saturadas y colesterol, puede reducir el riesgo de cardiopatía coronaria.

La soya también puede reducir los síntomas de menopausia y el riesgo de osteoporosis. Los productos de soya posiblemente pueden prevenir ciertos cánceres hormonodependientes, incluyendo cáncer de mama, cáncer del endometrio y cáncer de próstata.
