Information on phyto-oestrogen intake in various populations has been scanty until now, primarily because data on the content of these compounds in foods were lacking. [] Key Method The values, expressed as aglycones, were based on food analyses (mainly GC-MS) or imputed from analytical data for 180 foods for lignans and 160 foods for isoflavones; additionally, over 1000 values were derived from the recipe database of Fineli.

Phyto-oestrogens are dietary components found in some plants, which act in vivo like weak oestrogens. They may reduce the risk of some degenerative diseases moderated by oestrogen, including breast
Intakes and sources of isoflavones, lignans, enterolignans, coumestrol and soya-containing foods in the Norfolk arm of the European Prospective Investigation into Cancer and Nutrition (EPIC-Norfolk), from 7 d food diaries, using a newly updated database
The ability to estimate phyto-oestrogen intake in Western populations more accurately will aid investigations into their suggested effects on health.
Pilot Study to Assess Isoflavone Intake in Middle-Aged Italian Subjects
The total daily IF intake found was low and probably not sufficient to produce biological effects, however more studies are necessary to investigate whether low exposure to IF for a long time could have positive effects on human health.
Intakes and sources of soya foods and isoflavones in a UK population cohort study (EPIC-Norfolk)
Isoflavone intake is low in the UK but may be an underestimate due to soya added to commercial products, and the ability to estimate isoflavone intake in Western populations more accurately will enable investigations to be conducted into the suggested beneficial effects of phytoestrogens on health.
Phytoestrogen Content of Cereals and Cereal-Based Foods Consumed in the UK
This is the first study of phytoestrogens in a comprehensive selection of 101 cereals and cereal-based foods consumed in the UK using a sensitive LCMS technique with 13 C-labelled internal standards to allow a more accurate estimation of exposure to dietary phy toestrogens.
Validation of a Phytoestrogen Food Frequency Questionnaire with Urinary Concentrations of Isoflavones and Lignan Metabolites in Premenopausal Women
The results support the use of this FFQ as a measure of dietary isoflavone and lignan intake in epidemiological studies and support the association between dietary intake of phytoestrogens estimated by a food frequency questionnaire with urinary metabolites.
Dietary intake and main sources of plant lignans in five European countries
Cereals, grain products, vegetables, fruit and berries were the most important dietary sources of lignans according to the Dutch database in the five countries studied, compared to estimates based on the Finnish database based only on SECO and MAT.
Lignan intake in the Netherlands and its relation with mortality
In a prospective cohort study, in which 570 men aged 64-84 y were followed for 15 y, total lignan intake was not related with mortality, however, intake of MAT was inversely associated with coronary heart disease, cardiovascular diseases, cancer, and all-cause mortality.


Development of a database for assessing dietary phytoestrogen intake.
This work modified DietSys to include isoflavonoids, coumestans, lignans, phytosterols, and flavonoids in foods on the basis of published values and facilitated the identification of the major dietary contributors with phytoestrogen activity.
Naturally occurring oestrogens in foods--a review.
Indications are given of the wide range of common food plants which have been reported to possess oestrogenic (uterotropic) activity, although it is emphasized that in general further work is necessary to substantiate these claims and to confirm the identities of the biologically active principles which have in some cases been proposed.
Intake of dietary phytoestrogens is low in postmenopausal women in the United States: the Framingham study(1-4).
The aim of the present study was to estimate the intake of dietary isoflavones, coumestans and lignans by healthy Western postmenopausal women and identify food sources of phytoestrogens.
Isoflavone intake in four different European countries: the VENUS approach
The results (including a subgroup analysis of soya product consumers) showed that such levels are difficult to achieve with the European diets studied here.
Case-control study of phyto-oestrogens and breast cancer
Phytoestrogen intake and prostate cancer: a case-control study using a new database.
Results are suggestive of a possible relationship between phytoestrogen intake and prostate cancer risk, but larger comprehensive studies are needed to further refine the role of phy toestrogens intake in prostate cancerrisk.
Extraction and quantification of lignan phytoestrogens in food and human samples.
A simple preparative procedure for the assay of secoisolariciresinol, mataires inol, and shonanin in foodstuffs after hydrolytic removal of any conjugated carbohydrate is described.
Phyto-oestrogens: where are we now?
Investigation of the possible benefits of phyto-oestrogens is hampered by lack of analytical standards and, hence, inadequate methods for the measurement of low levels in most foods, which may prove to be a major dilemma for regulatory authorities, clinicians and others wishing to advise the general public on whether these compounds really do have the health benefits attributed to them.
Assessing Phytoestrogen Exposure in Epidemiologic Studies: Development of a Database (United States)
Agencies, such as the United States Department of Agriculture, that routinely provide data on food composition, on which epidemiologic investigations into dietary health effects are based, should consider instituting programs for the analysis of phytochemicals, including the phytoestrogens.

This chapter presents a review of studies on staple plant foods, indicating that plants contain, besides a wide range of chemicals with a number of biological properties, biologically active phytoestrogens--precursors of hormone-like compounds found in mammalian systems.
