Can You Eat Potatoes That Are Green Under The Skin?

Potatoes are a universally loved and versatile food, but what happens when you’re about to prepare a meal and notice green patches under the skin? This blog post unravels whether it’s safe to consume green potatoes, explains why they turn green, and provides guidance on how to handle them safely.

In a Nutshell

• Green potatoes contain solanine: a type of glycoalkaloid poison that can cause health issues if consumed in large amounts.
• Green coloration is a sign of increased solanine levels: though minor green patches can sometimes be safely peeled away.
• Prevent greening: by storing potatoes in a cool, dark place.
• Always handle potatoes carefully: if they’re green, it’s usually best to exercise caution and avoid consumption.

Understanding the Green Color

What Causes Potatoes to Turn Green?

Potatoes turn green due to chlorophyll accumulation caused by exposure to light. This process is natural and doesn’t automatically mean the potato is harmful. However, the presence of chlorophyll often indicates increased levels of solanine, a naturally occurring toxin.

The Role of Solanine

• Chlorophyll itself is harmless, but it signals elevated solanine levels in potatoes.
• **Solanine is a chemical compound*** that acts as a natural defense for plants but can be toxic to humans in high quantities.

Green potatoes should be approached with caution due to this association with solanine.

Health Risks of Consuming Green Potatoes

Potential Symptoms

Consuming high levels of solanine can lead to various symptoms, such as:

• Nausea
• Diarrhea
• Cramping
• Headaches
• Neurological disorders

While minor exposure is unlikely to cause severe harm, it’s always best to err on the side of caution.

When Is It Safe to Eat Green Potatoes?

• Trimming small green areas can reduce risk, but skepticism and prudence are advised if a significant portion of the potato is affected.
• Cooking does not completely eliminate solanine, so relying on peeling as the sole remedy is not advisable.

Factors Contributing to Potato Greening

Environmental Factors

Light exposure is the primary cause of greening. Factors contributing include:

• Improper storage conditions
• Extended exposure to sunlight in the grocery store or kitchen

Other Influences

• Temperature fluctuations can accelerate the greening process.
• Mechanical injury or damage can exacerbate solanine production.

Preventative Measures

Proper Storage

Store potatoes in a cool, dark, and well-ventilated place to prevent greening. Tips include:

• Use a burlap or brown paper bag for storage to limit light exposure.
• Avoid storing potatoes in the fridge as this can turn starch into sugar, altering texture and taste.

Regular Checks

• Regularly inspect your potatoes. Remove any that have started to green to prevent further spread.

Safe Preparation Techniques

Handling Green Potatoes

If you decide to consume slightly green potatoes, peel away all the green areas. Be mindful that cooking cannot entirely destroy solanine, but it may reduce its levels slightly.

Healthy Practices

• Always wash and scrub potatoes before cooking.
• Consuming them in moderation and combining them with a balanced diet can minimize potential risks.

FAQs

1. Why do potatoes turn green?
Potatoes turn green due to chlorophyll buildup following exposure to sunlight, which often signals increased solanine content.

2. Are all green potatoes poisonous?
Not all green potatoes are harmful, but they can be. It’s essential to judge each case individually and err on the side of caution.

3. Can I cook away the toxins?
Cooking does not fully eliminate solanine, so greening serves as a visual indicator to minimize exposure.

4. Is it safe to eat the non-green part of a green potato?
If peeling away the green part entirely is possible, the rest may be safe, but caution is advised.

5. How should I store potatoes to keep them from greening?
Store potatoes in a dark, cool place with good ventilation to slow down the greening process.

6. What symptoms indicate solanine poisoning?
Symptoms can include nausea, headaches, stomach cramps, and more, often occurring several hours after ingestion.

7. Where can I learn more about this topic?
