Can You Eat A Potato That Is Green?

Potatoes are a staple in cuisines worldwide, but sometimes, you might notice a green hue on your potatoes. What does this mean, and is it safe to consume them? In this blog post, we’ll explore the reasons behind the greening of potatoes, the potential health risks, and what you should do if you find a green potato in your pantry.

Essential Highlights

• Potatoes turn green due to the production of chlorophyll when exposed to light.
• Green potatoes may contain high levels of solanine, a toxic compound.
• Consuming green potatoes can lead to symptoms like nausea or headaches.
• It’s best to avoid eating green or sprouted potatoes to ensure safety.
• Peel or discard green parts and sprouts, but avoid consuming if a significant portion is green.

Understanding the Green Color

Potatoes turn green because they are developing chlorophyll. This is similar to the process that makes leaves green due to photosynthesis. While chlorophyll itself is harmless, its presence is a signal of increased levels of solanine, a glycoalkaloid toxin and natural defense mechanism of the plant.

• Exposure to Light: Potatoes exposed to light — natural or artificial — will typically start producing chlorophyll, leading to the characteristic green color.

Increased levels of solanine: When potatoes develop chlorophyll, solanine levels may rise, making the potato potentially unsafe to eat in large quantities.

Health Risks of Consuming Green Potatoes

Eating green potatoes can pose several health risks due to the solanine content that develops alongside chlorophyll.

• Symptoms of Solanine Poisoning:
  • Nausea
  • Vomiting
  • Diarrhea
  • Headaches
  • Neurological disturbances

The severity of these symptoms depends on the amount of green potato one consumes. As per the UK’s National Health Service on safe potato consumption, it is advised to avoid eating green or sprouted potatoes entirely.

Addressing the Safety Concerns

To minimize the health risks, take caution when consuming potatoes showing any green. Here are steps to help ensure safe consumption:

• Peel off the Green Parts: Often, solanine is concentrated in the skin and sprouted areas. Removing these parts can reduce the risk.
• Avoid Consuming Large Quantities: Even after removing the green parts, consider moderating your intake.

Preventive Measures and Storage Tips

Preventing potatoes from turning green is easier than dealing with them afterward. Proper storage can significantly prevent greening:

• Store in a Dark Place: Keep potatoes in a cool, dark area, like a pantry or a burlap sack.
• Avoid Washing Until Ready to Use: Moisture can promote sprouting alongside greening.
• Check Regularly: Regularly inspect your stored potatoes for any greening or sprouting and use them quickly.

FAQs About Green Potatoes

1. Can peeling a green potato make it safe to eat?

   • Yes, partially. By peeling off green parts and any sprouts, you reduce solanine content, but consider the extent of greening.
2. Are all varieties of potatoes equally prone to greening?
   • No, some varieties are more resistant due to thicker skins or genetic traits.
3. How quickly do potatoes turn green?
   • As quickly as a few days, dependent on light exposure. Proper storage inhibits this.
4. Can cooking destroy solanine in green potatoes?
   • No, solanine is heat-resistant and remains active even after cooking.
5. Why do some potatoes sprout without turning green?
   • Sprouting is a different process that occurs due to moisture, warmth, independently of greening.
6. Are small children more susceptible to solanine poisoning?
   • Yes, due to their smaller body mass and developing systems, children should avoid green potatoes more strictly.
7. How can I tell if a potato is too green to eat?
   • Color and extent. If a large portion or deeply saturated green appears, it’s best to discard it.
