Health and Functionality of Soy:7).Phytoestrogens and Soy Extract.:

The term phytoestrogens describes plant (or fungal) compounds that can elicit an oestrogenic response in mammals, at least under certain circumstances.

 Phytoestrogens are a group of phytochemicals currently under intense investigation for their role in the management of menopausal symptoms and in the prevention of chronic diseases such as cancer and cardiovascular disease.

 Also, the role of soy beans as a staple food and a major source of phytoestrogens is reviewed and the major soy constituents are identified.

 Phytoestrogens at a glance

 Isoflavones:
 occur principally in legumes
 soybeans and soy-based foods are the main dietary sources
 occur primarily as glycosides in plants
 the main isoflavone glycosides in soy are genistin and daidzin
 the corresponding aglycones are genistein and daidzein

 Lignans:
 primarily found in whole grains and seeds
 weaker phytoestrogens than the isoflavones
 linseed is the richest source
 main lignans in mammals are enterolactone and enterodiol


 Coumestans:
 occur chiefly in leguminous plants
 includes coumestrol, which is the most potent of phytoestrogens
 high levels in clovers, alfalfa and soy-bean sprouts

 Sources of phytoestrogens:
 Many plants, including major food species, contain phytoestrogens.
 Lignans occur in particularly high levels in linseed, but are also found in whole cereals, cereal bran, dried seaweeds, vegetables, legumes, and fruits.

 Plant lignans are not themselves oestrogenic, but rather serve as precursors to the so-called mammalian lignans, which form in mammals as a result of bacterial metabolism of the plant lignans in the gut.

 The main mammalian lignans are enterolactone and enterodiol; these form from the plant lignan precursors matairesinol and secoisolariciresinol.

 As is characteristic of phytoestrogens, both enterolactone and enterodiol can have either oestrogenic or anti-oestrogenic activity under different circumstances, as outlined below.

 The coumestans occur chiefly in leguminous plants. The main phytoestrogen in this group is coumestrol, which is also regarded as the most potent of phytoestrogenic compounds.
