Is it healthy to drink water soaked with corn sprouts? Corn sprouts do contain many nutrients and bioactive substances, but when drinking water boiled with corn sprouts or Congee or stewed soup boiled with corn sprouts, the nutrient content in the soup is very limited, so it is difficult to play its physiological function. Moreover, there is no clear research on how much water to use, how much corn silk to soak, how long to soak, and how long to drink to exert its effect.
