Will the baby's skin turn black if they eat soy sauce?

Patient's question:

No

Doctor's answer:

Eating soy sauce has no effect on skin color. Soy sauce is a traditional Chinese-flavored seasoning generally made through fermentation. In addition to a large amount of water, soy sauce mainly contains various nutrients such as amino acids and sugars that provide a savory taste. These amino acids are produced by the manufacturing process of soy sauce.
