Water-soluble vitamins

“Water-soluble vitamins” — nutrients that dissolve in water. These include vitamin C and the B vitamins. Water-soluble vitamins can easily be lost in cooking if they are allowed to leach into the cooking water, which is then discarded. This problem can be avoided by serving foods raw, cooking foods in as little water as possible, or including the cooking water in the finished dish (e.g., in a soup or stew).
