Heres Why Soy Sauce Is Bad For You

This will make you question your love for soy sauce!

Popular belief states soy sauce healthy, yummy and fat-free with high-antioxidant content. Soy sauce, made from fermented soybeans and wheat, is a flavourful and an important staple in Asian food. Natural production of soy sauce takes as long as 18 months and this way it is healthy and nourishing. However, commercial soy sauce takes only two to three days for production. This way, it can be potentially harmful to your health.

The high levels of salt in this sauce can also develop into a serious health hazard at a later stage in life. So in need of satisfying your taste buds, don't mess with your health!
