Potato
Overview
Why eat a potato?
Potatoes have a reputation as plain starch, but a medium one delivers more potassium than a banana's worth, nearly half a day's vitamin C, and a solid dose of vitamin B6 for only 164 calories. Keep the skin on and they bring useful fiber too.
Good to know: Most of the fiber sits in the skin, and how you cook a potato matters more than the potato itself: frying or loading it with butter adds far more fat and calories than the 0.09 g of fat it starts with.
Serious potassium source
One medium potato supplies 905 mg of potassium, 19% of the Daily Value, a mineral that helps balance sodium and supports healthy blood pressure.
Unexpected vitamin C
At 19.7 mg per 100 g, potatoes cover 22% of the Daily Value for vitamin C, which supports immune function and helps the body build collagen.
B6 and fiber together
A medium potato gives 37% of the Daily Value for vitamin B6, used in protein metabolism, plus 4.5 g of fiber that feeds gut bacteria.
