Beer turns men into women

Phytoestrogens, sometimes called "dietary estrogens", are a diverse group of naturally occurring non steroidal plant compounds that, because of their structural similarity with estradiol (17-β-estradiol), have the ability to cause estrogenic or/and antiestrogenic effects.

Phytoestrogen content varies in different foods, and may vary significantly within the same group of foods (e.g. soy beverages, tofu) depending on processing mechanisms and type of soy bean used. Legumes (in particular soybeans), whole grain cereals, and some seeds are high in phytoestrogen. A more comprehensive list of foods known to contain phytoestrogens includes: soy beans, tofu, tempeh, soy beverages, linseed (flax), sesame seeds, wheat, berries, oats, barley, dried beans, lentils, rice, alfalfa, mung beans, apples, carrots, pomegranates, wheat germ, ricebran, soy linseed bread, ginseng, bourbon and beer fennel and anise.
