Doesn't boiling a potato causes all water-soluble nutrients to leach out into the water. My grandmother used some of the water to add to the gravy.
Boiling does see some of the nutrients released, which is why homemade soup is good for you. However, it is the heat that destroys a lot of the nutrients, as nature didn't engineer them to be cooked.
