What is Light Soy Sauce?

Light soy sauce is a thinner, saltier, and lighter-colored version of traditional soy sauce.

Why it's used

Manufacturers add light soy sauce primarily for its savory, umami flavor and salty taste.

Its lighter color makes it ideal when a less intense color is desired compared to dark soy sauce.

Light soy sauce is generally recognized as safe (GRAS) by the FDA when used as a food ingredient. It is a significant source of sodium, and high sodium intake is linked to increased blood pressure in some individuals. JECFA has evaluated soy sauce and established guidelines for its use. Some studies suggest a link between high consumption of fermented soy products and certain health outcomes, but evidence is mixed and more research is needed.
