Where It Grows
Fermented soy sauce is not a naturally growing food but a product made through a fermentation process. This process can be carried out in various environmental conditions, but it generally requires controlled temperatures and moisture levels. The key ingredient, soybeans, are cultivated worldwide, with the largest producers being the United States, Brazil, and Argentina. However, the production and fermentation of soy sauce as a condiment is most prevalent in East Asia, particularly in China, Japan, and Korea, where it has been an integral part of food culture for centuries.
Best Way to Eat
Soy sauce is typically used as a condiment or seasoning in cooking rather than being consumed on its own. It is often used in marinades, dressings, and sauces to enhance the flavor of dishes. Due to its high sodium content, it should be used sparingly to control sodium intake. For a nutritionally beneficial use, opt for naturally brewed or fermented soy sauce over chemically produced versions, as the fermentation process produces beneficial compounds like antioxidants. Additionally, it can be paired with foods rich in vitamin C to help increase iron absorption.
