Can You Eat Green Potatoes?

Potatoes are a staple in many diets around the world, but what happens when they turn green? If you’ve ever wondered whether green potatoes are safe for consumption, this blog post will provide clarity. The greening of potatoes is a common occurrence, yet it can be alarming for many. This post will explore the science behind green potatoes, potential risks, and whether they belong on your plate.

In a Nutshell

• Why Potatoes Turn Green: Exposure to light causes chlorophyll to develop, but this also increases levels of toxic solanine.
• Health Risks: Eating green potatoes can cause nausea, headaches, and, in severe cases, neurological problems due to solanine toxicity.
• Safety Measures: Removing the green parts and peeling the potato may reduce toxicity.
• Consumption Advice: It’s generally safer to avoid eating green potatoes entirely.

Why Do Potatoes Turn Green?

Green potatoes are a result of exposure to light. This exposure stimulates the production of chlorophyll, the green pigment seen in leaves and plants. While chlorophyll itself is harmless, its presence in potatoes indicates increased solanine levels. Solanine is a glycoalkaloid poison that is naturally found in nightshade vegetables. While chlorophyll isn’t harmful, solanine is the real concern.

• Exposure to light, whether during growth or storage, causes the greening.
• Greening acts as a protective mechanism for the potato plant against predators.
• Fun Fact: Chlorophyll is responsible for photosynthesis in plants.

The Dangers of Eating Green Potatoes

Consuming green potatoes can be harmful. The increased solanine levels pose serious health risks:

• Symptoms of solanine poisoning: Nausea, vomiting, diarrhea, abdominal pain, and neurological disturbances like headaches, dizziness, and in severe cases, hallucinations or even paralysis.
• Even small amounts of solanine can cause adverse effects.
• Threshold of safety: About 20 milligrams per 100 grams of potato can cause symptoms in adults. Much less might trigger symptoms in children.

How to Safely Consume Potatoes

If you’re determined to use green potatoes, there are precautions to take. The best option is to avoid them altogether, but you can lower the risk by:

• Peeling the potato: This removes the majority of solanine as it’s concentrated in the skin and just beneath it.
• Cutting away the green parts: Dispose of parts that have turned green or sprouted.
• Cooking doesn’t effectively reduce solanine, so don’t rely on heat to neutralize the toxins.

Safe handling and storage can prevent potatoes from greening. Storing potatoes in a dark, cool place can maintain their freshness and safety.

Conclusion

It’s generally safer to avoid eating green potatoes. While peeling and removing green parts can reduce the solanine levels, the risk may still exist. To ensure your health and safety, it’s recommended to consume potatoes that are fresh and free from discoloration.

FAQs

1. Why do potatoes turn green when exposed to light?
   • Light activates chlorophyll and increases solanine, which both cause greening in potatoes.
2. Can peeling a green potato make it safe to eat?
   • Peeling removes much of the solanine, but completely eliminating the risk might be difficult, hence caution is advised.
3. What symptoms indicate solanine poisoning?
   • Symptoms include nausea, vomiting, diarrhea, stomach cramps, headaches, and neurological effects like dizziness.
4. How can I store potatoes to prevent them from turning green?
   • Store them in a cool, dark, and dry place to discourage exposure to light and minimize solanine production.
5. Is cooking effective against solanine in green potatoes?
   • Unfortunately, cooking doesn’t significantly reduce solanine levels, so green areas must be removed prior to cooking.
6. Are small green spots on potatoes safe if removed?
   • While removing small green spots can help, it’s typically safest to avoid any green version of the tuber entirely.
