There is estrogen in soy as soy contains a high concentration of a plant estrogen (phytoestrogen) also known as isoflavones which are similar in function to the human estrogen but with much weaker effects.
The soy isoflavones can bind to estrogen receptors inside the body and cause either weak estrogenic or anti-estrogenic activity.
The foods that are high in estrogen are flaxseed, soybean and soybean products, chocolate, fruits and vegetables, chickpeas, legumes, Rye bread, nuts, walnuts, almonds, peanuts, sunflower seeds, sesame seeds, plums, pears, peaches, grapes, berries and apples.
Red Wine is also a good source of estrogen.
Red wine may contain higher levels of phytoestrogens due to its fermentation process.
Beer also contains phytoestrogens, and its effect can be seen even with moderate intake.
Hard liquor is metabolized faster than beer or wine, so it may have a more immediate effect on estrogen levels.
Estrogens are a group of hormones that play an important role in the normal sexual and reproductive development in women.
The estrogens are also sex hormones.
A woman's ovaries make most estrogen hormones, although the adrenal glands and fat cells also make small amounts of the hormones.
Low estrogen levels in women can cause symptoms including irregular periods, hot flashes, painful sex, headaches, mood swings, and more.
The most common cause of low estrogen is menopause. But too much exercise, disordered eating, or complications with your ovaries could also lead to lower levels.
And in men estrogens exert pleiotropic effects by acting on several tissue and organs, including the male reproductive system.
The action of estrogens is manifest from prenatal life during which the exposure to estrogen excess might influence the development of some structures of the male reproductive tract.
Although the male body needs estrogen to function correctly, too much estrogen can cause health problems.
Increased levels of estrogen can cause symptoms such as infertility, erectile dysfunction, and depression.
A person who is concerned about their estrogen levels should contact their doctor.
