Phytoestrogens in animal origin foods - Bibu John Kariyil
Vet World. 2010; 3(1): 43-45
Abstract
Phytoestrogens are
a group of polyphenolic plant
metabolites that can induce biological responses. Their
bioactivity is based on their similarity to 17ß-estradiol and
their ability to bind to the ß-estrogen receptor. Reliable
information on the phytoestrogen content
in foods is required to assess dietary exposure and disease risk
in epidemiological studies. However, existing analyses have
focused on only one class of these compounds in plant-based
foods, and there is only little information on foods of animal
origin, leading to an underestimation of intake. Although
epidemiological data are inconclusive,phytoestrogens are
considered to be beneficial for a variety of conditions. To
investigate the biological effects of these compounds and to
assess the exposure of larger cohorts or the general public,
reliable data on the phytoestrogen content
of food is necessary. The analysis of phytoestrogens in
food is done by using automated solid-phase extraction and
liquid chromatography-tandem mass spectrometry.
