The humble potato has an intriguing history and has become one of the most important food sources on Earth. Here are 13 fascinating potato facts that may surprise you.

A Brief History

Potatoes originated in Peru. Archaeological evidence shows that potatoes were first cultivated by the Incas around 8,000 BC to 5,000 B.C. The Incas prized the potato for its ability to grow in poor soil and at high elevations.

Potatoes were brought to Europe in the 16th century. Spanish conquistadors invading Peru discovered the potato and brought it back to Europe around 1570. At first, Europeans were wary of the strange new vegetable, believing that it caused diseases like leprosy. However, by the 1800s, the potato had become a staple crop across Europe as its excellent nutritional value and ease of growth was recognized.


  • Potatoes are fat-free, sodium-free, and high in vitamin C and potassium. One medium baked potato with skin provides 110 calories, 0 grams fat, 0 grams sodium, 24 grams carbohydrates, 2 grams protein, 27% Daily Value of vitamin C, and 620 milligrams potassium.
  • The potato skin contains at least 50% of the total dietary fiber, vitamin C, iron, potassium, zinc and magnesium. So keep the skin on for maximum nutritional benefit!
  • Potatoes contain antioxidants like carotenoids, flavonoids, and caffeic acid. These antioxidants can help neutralize free radicals which cause cell damage in the body and contribute to aging and disease.

Growing Potatoes

  • Potatoes are grown by planting “seed potatoes” which grow into potato plants producing more potatoes underground.
  • Each seed potato should yield around 6-12 potatoes. The average yield worldwide is around 9 million tons per hectare.
  • Potatoes thrive in cool climates with steady moisture, and lots of space for their root systems to spread out. They take around 90-120 days to reach maturity.
  • Potatoes intended for storage should be dug up only when vines have died back and skins are firm. Store cured potatoes in a cool dark place at around 40-50°F.

Fun Facts

  • Potatoes can reflect wifi signal. Using an aluminum foil covered potato as a wifi signal booster actually works! The starch and water in the potato absorb and amplify the signal.
  • Potato plants produce tomatoes-like fruits when allowed to flower, that resemble small green tomatoes and contain true potato seeds. These seeds can be saved and replanted.
  • Potatoes shouldn’t be refrigerated below 50°F as cold temperatures convert their starch content to sugar giving them an unpleasant sweet taste.
  • Mr. Potato Head was the first toy to be advertised on TV and has been a toy since 1952.
  • Potatoes were taken to space by NASA to grow food and test crop production in space.
