You may think of citrus fruits as the vitamin C powerhouses, but potatoes, including the skins, are good sources of this immunity-boosting vitamin. Potato skins also contain B vitamins, calcium and other nutrients. Potato skins are also rich in phytochemicals.
When boiling potatoes, it is best to leave the skin on while cooking--the potato will retain more nutrients and flavor. Skins can be removed as soon as the potato is cool enough to hold. Potatoes should be scrubbed before boiling, rather than soaked. Soaking potatoes in water can sap nutrients and flavor.
