Soya Milk, also written as soy milk, is a milk substitute that is made for soy bean. The major benefit of soy milk is that it has the same amount of protein as normal milk, but without the protein lactose. Soy milk also has little saturated fat and no cholesterol as compared to regular milk.

In order to make soy milk, the soy beans are first soaked in water, and then grinded into paste. This paste is then mixed with water and boiled for a certain amount of time. After which, the milk solution is then filtered to remove the insoluble soy milk fiber. The filtered milk is what is called soy milk.

While soy milk has recently gained popularity, it has been in existence since 200 BCE. It was first used in China, but it was not regularly consumed until the 1800s, and was introduced to the western world much later.
