What is soy milk and how is it obtained?

Soy milk is a derivative of soybean (Glycine max), a legume native to Asia. For its preparation, soya beans are ground, boiled, and filtered, until a liquid of white color reminiscent of milk. Subsequently, enzymes are often added that are responsible for converting the starches naturally present in the soy beverage into simple sugars, such as maltose, in order to achieve sweetening the beverage without adding sugar. Other times, sugar, cocoa, vanilla or other flavorings are added.

Allergy to soy protein

Soy drink is contraindicated for people with soy allergy. These people should not consume soy milk because it could cause severe allergic reactions, even anaphylactic shock.

Sometimes, these other vegetable drinks are processed in factories where soybean has also been handled, so it is recommended to check in the container of any type of vegetable drink that the product can not contain soy or traces of soy.

Does soy milk produce feminization?

Soy has some components called isoflavones (phytoestrogens), which in the body have an effect similar to estrogen (although its effect is less powerful). The properties of soy for menopause are well known due to its isoflavones genistein, daidzein and glycitein.

Although this estrogenic effect may be adequate in some cases as in menopause, it has also been said that the consumption of soy (and by extension, soy milk) could produce feminization in men, or help increase the size of the bust in women. The truth is that none of these possible effects has been proven.

Anyway, soy milk contains very little isoflavones, unless they are enriched especially in these components.
