Potato FAQs

Can a person live on only potatoes?

Yes, potatoes provide all of the nutrients required to live a healthy and active life.  There are numerous accounts of people going on potato only diets any where from two months to a full year with resulting improvements in health markers and often weight loss. The protein in potatoes is complete and readily available, however it does not occur in significant quantities, so for growing children or those desiring to add muscle mass it is recommended to add lean proteins like non-fat milk or seafood.

Will consuming potatoes with green patches make me sick?

  • Green spots or patches on potatoes (known as “greening”) are a natural result of chlorophyll production in the tuber from being exposed to light.

How do I properly store and handle potatoes after purchase?

  • Store potatoes in a cool, well-ventilated place.
  • Keep potatoes out of the light.
  • Cold temperatures, lower than 50 degrees in the refrigerator, cause a potato’s starch to convert to sugar, resulting in a sweet taste and discoloration when cooked.
  • Avoid areas that reach high temperatures (beneath the sink or beside large appliances) or receive too much sunlight (on the countertop).
  • Perforated plastic bags and paper bags offer the best environment for extending the shelf life of potatoes
  • Don’t wash potatoes, or any produce, before storing. Dampness promotes early spoilage
