Potassium
Potatoes with skin are an excellent source of potassium, which is great for cardiovascular health. In fact, potatoes qualify for a health claim approved by the U.S. Food and Drug Administration,
which states: Diets containing foods that are a good source of potassium and that are low in sodium may reduce the risk of high blood pressure and stroke. Just one potato offers 21-percent
of the Daily Value for potassium. Potassium also helps retain calcium, which is important to build strong bones.
Vitamin C
For vitamin C, think potatoes! Potatoes are one of the
leading sources of vitamin C in the American diet. This vitamin
is a potent antioxidant that helps stabilize free radicals, which
may prevent cellular damage. Vitamin C also produces the collagen
that helps hold bone tissue together.
Fiber
One medium potato (5.3 ounces) with skin contains three grams,
or 12-percent of the recommended daily intake for fiber.
Preliminary studies show that fiber is beneficial for a healthy
digestive system and may help reduce the risk of some cancers
and possibly heart disease. Consuming adequate fiber and
water helps increase satiety between meals.
Antioxidants
Potatoes contain glutathione, an antioxidant that may possibly help
protect against some cancers. Per serving, potatoes, along with
avocadoes, asparagus, squash, okra, cauliflower, broccoli and raw
tomatoes, have the highest glutathione content compared to other vegetables.
In a study comparing the overall antioxidant activity of potatoes, bell peppers, onions and broccoli, potatoes ranked second highest after broccoli.
