Can you cook green potatoes?

No, you can not cook green potatoes. The green color of potatoes is considered as a great indicator for the presence of a harmful toxin. That’s why green potatoes are so dangerous to eat. For more information about green potatoes, just keep reading this article.

What is the cause of the green color of potatoes?

When potatoes are not stored in a proper way or when they are exposed to light, they will often go green.

Exposure of potatoes to light allows them to produce chlorophyll which is the pigment that turns potatoes green, chlorophyll on its own is completely harmless, however it can signal the presence of dangerous toxins.

How can green potatoes be toxic?

When exposure to light encourages potatoes to produce chlorophyll, it can also encourage the production of other compounds that protect the plants against insects and bacteria. These compounds protect the bacteria, but they are very harmful and toxic to humans. So, these compounds are considered as toxins.

What is the main toxin found in green potatoes?

The main toxin that is found in green potatoes is called solanine. Solanine is very dangerous to humans. Potatoes that contain high levels of solanine can cause nausea, vomiting and headaches. In severe cases, solanine can cause paralysis, coma or even death.

How does solanine act in the human body?

Solanine can be considered as a neurotoxin and it mainly acts through two mechanisms:

  • Through inhibiting a certain enzyme which is involved in the breaking down of certain neurotransmitters.
  • Through damaging cell membranes which can negatively affect your intestine’s permeability.

Can peeling or boiling of green potatoes be effective?

Solanine levels are the highest in the skin of green potatoes so, yes peeling can help reduce the solanine levels. However, green potatoes that contain very high concentrations of solanine would still contain high enough solanine levels to make you sick even after peeling so, to be on the safe side, it is best to throw it away.

Unfortunately, boiling and any other cooking method including baking, microwaving or frying will not reduce the solanine levels in green potatoes. Also to be on the safe side, throw away any potatoes that have a green skin or that are bitter in taste ( a sign of solanine).

How can you protect potatoes from turning green?

You can save the potatoes and prevent them from turning green:

  • Store the potatoes in a cool dark place such as the basement.
  • Potatoes should be stored in an opaque sack or plastic bag in order to shield them from light.
  • Don’t store potatoes in the refrigerator as it is too cool for potato storage. Actually, some studies found that solanine levels may increase due to storage at refrigerator temperatures.
  • Only purchase the amount of potatoes that you plan to use and protect them from light and warmth through storing them in the back of the cabinet or drawer.
  • If you see green potatoes in the supermarket, alert somebody to save lives or to at least prevent a lot of stomach aches.

What are the side effects of solanine?

  • Fever is considered as a hallmark of food poisoning.
  • Headache.
  • Pain in the stomach.
  • Pain in the abdomen.
  • Diarrhea and vomiting are also considered as hallmarks of spoiled or bad food.
  • Lower body temperature than normal.
  • Slow pulse and slow breathing.

Can you serve green potatoes to children and what should you do if you ingest solanine?

Green potatoes can not be served to anyone especially children as their smaller bodies make them even more susceptible to poisoning. You should seek immediate medical advice if you believe that you have any solanine poisoning symptoms from ingesting green potatoes
