What you need to know

Soy is derived from “soybeans” which are a species of legume native from East Asia.
Soybean is a very cheap high source of protein that can be modified to be used as a substitute for many foods. For example, Soy milk, Soy sauce, Soy paste, Soy meal, Soy flour, Tempeh, Edamame, Tofu, Soy Lecithin and Soybean oil; are derived from Soybeans.

Facts

• The main countries growing soybeans are the United States (32% of world total, 2016 forecast), Brazil (31%) and Argentina (18%).

• Soy provides all 3 macronutrients: protein, fat, and carbohydrate
  From 100 grams, or a handful of soybeans, you get 446 calories, 9% of that is water, 30% carbohydrates, 20% total fat (including saturated, mono-and polyunsaturated) and 36% protein. And 19 minerals including magnesium, and arginine which may stimulate fat-burning

• Consumption of soy protein has been linked with a modest decrease in cholesterol levels. Soybeans also contain bioactive proteins, such as lectin and lunasin, which may have anticancer properties.

• Being low in carbs, whole soybeans are very low on the glycemic index, which is a measure of how foods affect the rise in blood sugar after a meal. The low glycemic index makes soybeans particularly suitable for people with diabetes. Soybeans contain a fair amount of both soluble and insoluble fibers.

• Soybeans contain isoflavones, which are chemically similar to estrogens.
  Soy contains phytoestrogens called isoflavones that may mimic the activity of the hormone estrogen in your body.

• Soy is a good source of protein for vegetarians and vegans or for people who want to reduce the amount of meat they eat. According to the US Food and Drug Administration. In fact, soy protein may be better for our kidneys than animal protein, since it contains low amounts of the amino acid methionine, which may improve our lifespan.

Chemistry

Soy protein contains two hormone-like substances called genistein and daidzein, which have a structure and function similar to the human hormone estrogen. When ingested in large quantities, these phytoestrogens cause your estrogen levels to rise. High estrogen levels may theoretically stimulate the production of breast tissue and lead to gynecomastia. However, there are no studies to demonstrate that soy has this effect on human tissue.

Conclusion:

Don't worry... Soy will NOT give you men boobs! Keep drinking soy milk if that's what you like. Eat your edamame, drink your soy protein shake, have your favorite soy snack, etc... Life is too short to worry about a large breast (YOLO);
It's ironic how we love them on women but don't want them on us.
