Understanding Green Potatoes

Green potatoes develop their colour due to exposure to light, which increases chlorophyll and solanine levels. Chlorophyll itself isn’t harmful; however, its presence indicates increased solanine, which can be toxic.

• Solanine is a type of glycoalkaloid and serves as a natural pesticide within potatoes.
• While solanine is naturally occurring, high amounts cause major safety concerns.

For more insight into the effects of solanine, visit the NHS website.

Health Risks Associated with Eating Green Potatoes

Consuming green potatoes poses several health risks primarily due to solanine. Symptoms of solanine poisoning can range from mild to severe:

• Nausea and vomiting
• Diarrhea
• Headaches and dizziness

In extreme cases, solanine poisoning can lead to more severe neurological and gastrointestinal issues. The Food Safety Agency provides more details on food safety standards.

Safe Handling and Storage

Proper storage of potatoes can prevent them from turning green. Here are some tips to minimize the risk:

• Store potatoes in a cool, dry, and dark place.
• Use paper bags or containers that limit light exposure.
• Inspect regularly for any signs of green spots.

If you notice a potato has turned green, it’s best to discard it or at least cut away all green areas.

• Purchasing potatoes in amounts that can be consumed in a short time.
• Opting for potato varieties less susceptible to greening.
• Regularly checking your potatoes for any discolouration.

FAQ

1. Why do potatoes turn green?
Potatoes turn green primarily due to exposure to light, which increases chlorophyll and solanine levels.

2. Is all discoloration in potatoes harmful?
Not all discolouration indicates harm, but greening typically signals increased solanine levels, which poses health risks.

3. Can peeling green potatoes make them safe?
Peeling can reduce the risk by removing some of the solanine, but it’s safer to avoid eating them altogether.

4. How can I store potatoes to prevent them from greening?
Store them in a cool, dark, and dry place, ideally in paper bags or light-blocking containers.

5. Are immature potatoes more likely to become green?
Yes, immature potatoes are more prone to develop chlorophyll and solanine upon exposure to light.

6. What should I do if I’ve eaten green potatoes?
If you experience symptoms like nausea or headaches, seek medical attention to manage potential solanine poisoning.
