Soy sauce’s origins are in China where it began as a soy paste called jiang. Jiang was made from fermented soybeans but in the Zhou Dynasty, the term included all kinds of preserved foods including meat, grain, and seaweed. Later on, during the Han Dynasty soybeans had become more popular. Soy sauce was already being referred to by its modern name — jiangyou — at the start of the Song Dynasty.
The earliest forms of soy sauce came about in an era where food preservation largely revolved around pickling. People had found that the process also enhanced flavor in addition to its preservative benefits. The microorganisms responsible for the fermentation also broke down proteins resulting in what we call umami.
In ancient China, wheat and soybean were among the most widely available ingredients, which is why soy sauce developed the way it did. Eventually, jiang made with grain became popular in other Asian countries so that Japan and Korea all eventually developed their own versions.
Soy sauce wouldn’t get to Japan until the 13th century. It was introduced there by Buddhist monks who called it shoyu, which is the source of the English word soy. While the Japanese were just becoming familiar with soy sauce, the recipes for it were continuing to evolve back in China. It was the most popular seasoning in China by the start of the Qing Dynasty in 1644.
By the 17th century, soy sauce had become known in the West and the failed attempt to replicate it is most likely what resulted in Worcestershire sauce. The soy sauce variety most familiar to Westerners is the thinner light soy sauce. It is more watery and has a higher salt content when compared to thick soy sauce, which has molasses added to give it more body.
Today, soy sauce continues to play a key role in many Asian cuisines and is one of the most popular condiments in the US.

Health benefits of soy sauce
Soy sauce has several healthy compounds that come from the soybeans and wheat used to make it. Some of those compounds may also be the result of the fermentation process, here are some of the nutrients that make soy sauce a healthy addition to your diet:
- Protein: Soy sauce provides a relatively high amount of protein per serving, which you need to build tissues.
- B vitamins: You can get a significant amount of vitamins like vitamins B2 and B3 from soy sauce.
- Minerals: Soy sauce contains some important mineral nutrients like iron and phosphorus.
With soy sauce in your diet, you can treat or prevent conditions like:
- Obesity: Because soy sauce is low in calories but high in flavor, you can use it to enhance the flavor of low-fat foods without increasing their caloric load.
- High blood pressure: People with high blood pressure are often told to avoid sodium. Sodium is present in soy sauce but less of it is necessary to provide the same amount of saltiness as salt, which means that you can use soy sauce to lessen your salt consumption.
Soy sauce is used as a table condiment for dipping and sprinkling and in a wide range of Asian dishes including fried rice.
