Potatoes are Good for You

Potatoes are:

  • a vegetable.
  • a good source of vitamins B and C.
  • a source of minerals.
  • high in complex carbohydrates.
  • high in fiber, if the skins are eaten.
  • fat-free. 
  • about 3 medium potatoes.

How to Buy Potatoes

Choose clean, firm, smooth potatoes with no sprouts or greenish color.

One pound of fresh potatoes equals:

  • about 3 medium potatoes.
  • 3 cups peeled and sliced potatoes.
  • 2 cups mashed potatoes.
  • 2 cups French-fries.

Potato Types

Round red or white potatoes have a thin outer skin. They are good for boiling and stewing.

New potatoes are freshly harvested. They are sweet and moist and good for boiling and stewing.

Russets are oblong with thick outer skins. They are good for baking and make excellent mashed potatoes.

In addition, red- and yellow-fleshed potatoes (such as Yukon Gold) are sometimes available.

How to Store Potatoes

  • Handle potatoes gently. Bruised potatoes turn dark and begin to rot.
  • Store potatoes in a cool (45-50 °F.), humid (not wet), dark place with good ventilation. When potatoes are correctly stored, they will remain fresh for up to a month.
  • If potatoes are stored in a warm place, such as under the sink, they may attract bugs and rodents. They will sprout and shrivel. Throw away potatoes that are shriveled or have many sprouts.
  • If potatoes are stored where they are exposed to light, they turn green, produce a toxic substance, and develop a bitter flavor. Peel off green areas before using. Throw away potatoes that are mostly green.
  • If potatoes are stored at temperatures below 40 °F. or in the refrigerator, they develop a sweet taste and turn brown when cooked. If potatoes get cold, warm them to room temperature before cooking.
