Sunflower Seeds and Cholesterol Reduction

Researchers have known that nuts and seeds are rich sources of phytosterols, a class of plant chemicals that have been shown to reduce cholesterol levels and improve heart health.

In what is believed to be the most comprehensive analysis to-date of the phytosterol content of nuts and seeds, chemists at Virginia Polytechnic Institute and State University in Blacksburg, VA., analyzed some 27 nut and seed products that are most commonly consumed as snack foods in the United States.

The researchers found that pistachios and sunflower kernels had the highest levels of phytosterols among the nuts and seeds studied. Their research appears in the November 30, 2005 issue of the American Chemical Society's Journal of Agricultural and Food Chemistry.

Los investigadores han demostrado que los frutos secos y las semillas son fuentes ricas en fitosteroles, una clase de compuestos químicos de origen vegetal que se ha demostrado útil para reducir niveles del colesterol y para mejorar la salud del corazón.

En un estudio que puede ser hasta la fecha el análisis más exhaustivo sobre el contenido de fitosteroles en frutos secos y semillas, el equipo de bioquímicos del Instituto Politécnico de Virginia y la State University en Blacksburg en Virginia, analizaron 27 clases de frutos secos y semillas que se consumen más comúnmente como snacks en Estados Unidos.

Los resultados demostraron que los pistachos y las pipas de girasol tienen los niveles más altos de esta sustancia. La investigación se publicó en el número del 30 de Noviembre de 2005 del "American Chemical Society's Journal of Agricultural and Food Chemistry".
