Is it okay to cook with tap water?

　　Can I cook rice directly with tap water?

　　In fact, unboiled tap water contains a lot of chlorine. During the cooking process, the chlorine in the water will destroy the vitamin B1 in the rice. Over time, the human body will develop a series of symptoms such as indigestion and dermatitis. The correct way to cook rice is to boil tap water first and then pour the rice in. This way the chlorine in the water has basically evaporated, which will reduce the loss of vitamin B1.
