Is it true that if you eat too much broccoli it will turn your urine green?
assistant
Yes, it is true. Broccoli contains a chemical called glucoraphanin, which is broken down in the body to form a compound called sulforaphane. Sulforaphane is responsible for the color of broccoli and other cruciferous vegetables. When eaten in large amounts, it can cause your urine to turn green.
