Are whole boiled potatoes healthier than cut up in mashed potatoes?

Yes, whole boiled potatoes are healthier than cut up in mashed potatoes. When potatoes are cut up, the surface area of the potato is increased, which allows more nutrients to be lost into the cooking water. Additionally, when potatoes are mashed, the starch in the potatoes is broken down, which makes them more quickly digested and absorbed by the body, leading to a higher insulin response. Therefore, whole boiled potatoes are a healthier option as they are a good source of fiber and other important nutrients, and are digested more slowly.
