Abstract
Description
El desarrollo de alimentos funcionales en los últimos años ha ido en aumento debido principalmente, al interés de la población por alimentos que no solo cumplan con la función nutricional sino también por que tengan un efecto benéfico en salud reduciendo así el riesgo a padecer diversas enfermedades. La alfalfa ha sido generalmente un alimento destinado para la alimentación del ganado, sin embargo, en diversas investigaciones alrededor del mundo se ha reportado que contiene compuestos bioactivos –fitoquímicos– y proteínas con efecto estrogénico, antimicrobiano y antioxidante, así como también protector contra enfermedades cardiovasculares, cáncer y diabetes, entre otras, clasificándola potencialmente como un alimento funcional. El presente documento tiene como objetivo dar un bosquejo general informativo a través de la búsqueda y revisión bibliográfica acerca de los alimentos funcionales y en especial de la alfalfa y constituyentes fitoquímicos (fitoestrógenos) que la ubican dentro de este grupo de alimentos; así como los hallazgos que se han reportado como efectos adversos en animales experimentales específicamente en el aparato reproductivo debido al consumo de este tipo de fitocompuestos. Esta dicotomía entre los efectos adversos y benéficos no es más que la señalización de que aún falta mucha más información y estudios que realizar respecto al resultado que pueden tener los fitoestrógenos en el desarrollo y función reproductiva de animales, el agonismo y antagonismo de su efecto así como la concordancia en el riesgo-beneficio de su consumo.
Functional food development has been increased during the last years due to the population interest in foods that have not only a nutritional function but a health benefit as well reducing the risk of suffering several diseases. Alfalfa has been intended as cattle feed, although several investigations have reported that alfalfa contains bioactive compounds –phytochemicals- proteins with an estrogenic effect, and antimicrobial and antioxidant compounds, being classified as a functional food with protection against cancer, diabetes and cardiovascular and other diseases. The aim of the present study is to offer a general information outline, through a bibliographic review, of functional foods’ status, focusing on alfalfa and its phytochemicals (phytoestrogens), compounds that give it its functional food character and its adverse effects shown in the reproductive system of experimental animals as well. Such dichotomy between adverse and beneficial effects is the sign that shows that it is needed more information and more studies to be done in order to establish the effect of phytoestrogens in the development and reproductive function in animals, its agonistic and antagonistic effect and risk-benefit balance in its consumption.
