What Does It Mean When a Potato Is Green?
When a potato turns green, it generally means that it has been exposed to light.
This exposure leads to the production of chlorophyll and solanine, a toxin found in potatoes.
While small green spots or sprouts can be trimmed off, if there are larger areas of green on the potato, it should be thrown out.
Green potatoes can have a bitter taste and should not be eaten, especially by children who are more susceptible to solanine.
It is important to inspect potatoes before purchasing and avoid buying ones that have started to turn green.
To prevent potatoes from turning green, store them in a cool, dark space with good air circulation, as exposing them to sunlight or damage can increase solanine levels.
Quick Tips and Facts:
1. Did you know that when a potato turns green, it means it has been exposed to sunlight for too long? The greening occurs due to the potato producing chlorophyll to protect itself from the sun, similar to how plants do.
2. Green potatoes can actually be harmful if consumed in large quantities. They contain a toxic compound called solanine, which can cause nausea, vomiting, headaches, and even paralysis. It’s best to peel or cut off the green parts before cooking or consuming potatoes.
3. Interestingly, green potatoes can be used as a natural dye! The chlorophyll in the green parts can create beautiful shades of green when used to dye fabrics or other materials. It’s a fun eco-friendly alternative to chemical dyes.
4. Green potatoes are also a sign of age. As potatoes age, they naturally produce more solanine, making them more likely to turn green. This is why green potatoes are often found in storage rather than fresh produce.
5. Have you ever wondered why potato chips rarely have green ones? That’s because potato chip manufacturers use specific varieties of potatoes with lower levels of solanine. Additionally, the slicing and cooking process tends to eliminate most of the green parts, ensuring the chips remain a delicious crispy treat!
Causes And Effects Of Green Potatoes
Potatoes are a staple food enjoyed by millions of people around the world. However, sometimes we encounter green potatoes, which can be a cause for concern. The green color of these potatoes is caused by exposure to light, specifically ultraviolet (UV) light. When exposed to light, potatoes produce chlorophyll, the pigment responsible for the green coloration. While some may think that green potatoes are just a harmless quirk, they can actually signal the presence of a potentially harmful toxin called solanine.
When potatoes are exposed to excessive light, whether it be natural sunlight or artificial light, they heal themselves by producing chlorophyll to protect against harmful UV rays. This is why potatoes turn green. The greening occurs primarily in the outer skin of the potato, which is the part exposed to light. Additionally, chlorophyll itself is harmless and does not pose a health risk to humans. However, the real concern lies in the presence of solanine.
Solanine is a natural toxin found in potatoes, specifically in their skin and flesh. It is present in low levels, usually not causing any harm. However, when potatoes are damaged or exposed to sunlight, the solanine content can increase significantly. Higher amounts of solanine can lead to adverse effects on human health, including gastrointestinal problems and other negative symptoms.

Dangers Of Eating Green Potatoes
Eating green potatoes, especially in large quantities, can be potentially harmful. This is primarily due to the increased levels of solanine found in green potatoes. Solanine poisoning is not common, but it can occur if high levels of this toxin are ingested.
Symptoms of solanine poisoning can include gastrointestinal issues such as diarrhea and vomiting, as well as abdominal pain, sweating, and headaches. These symptoms are generally mild and resolve on their own within a few days. However, severe cases of solanine poisoning are rare but can cause more serious complications.
It is important to note that children are more susceptible to solanine poisoning than adults. Their smaller body size and developing digestive systems make them more vulnerable to the effects of toxins. Therefore, it is advisable to avoid serving green potatoes to children to minimize the risk of solanine poisoning.

Preventing Green Potatoes
The best way to prevent potatoes from turning green is by storing them properly. Potatoes should be kept in a cool, dark space with good air circulation. Ideally, they should be stored in a pantry or drawer away from light sources such as windows or direct exposure to artificial light.
Refrigeration is not recommended for potato storage, as the temperature is too cold and can actually increase solanine levels. Instead, opt for a cool and dry environment. Regularly check your potato supply and discard any potatoes that have started to turn green or have become excessively sprouted.
Proper storage alone may not be enough to prevent all cases of greening, especially if potatoes have been physically damaged or bruised during handling. Hence, it is crucial to carefully inspect potatoes before purchasing. Avoid buying potatoes with any signs of sprouting or those that already have green spots on their skin.
Checking Potatoes For Green Spots
When inspecting potatoes for green spots, it is essential to understand that the green coloration is an indication of the presence of solanine. Green spots on the skin of the potato indicate that the solanine levels may be higher in those areas. As mentioned earlier, small green spots can be trimmed off, and the remainder of the potato can still be consumed safely.
However, if the green coloration extends beyond small spots and covers a significant portion of the potato, it is better to err on the side of caution and discard the entire potato. This is because the solanine levels may be too high for it to be considered safe for consumption.
In addition to green spots, another factor to consider is the taste of the potato. Potatoes containing excessive solanine can have a bitter taste. If a potato tastes bitter or causes a burning sensation in the mouth, it is recommended to refrain from eating it as it may contain elevated levels of the toxin.
- Green spots indicate presence of solanine
- Small green spots can be trimmed off safely
- Discard entire potato if green coloration covers significant portion
- Bitter taste or burning sensation may indicate elevated solanine levels.
The Presence And Effects Of Solanine
Solanine is a natural defense mechanism found in potatoes to protect against pests and predators. Most potato varieties contain solanine in low levels, but it can increase when the potato is damaged or exposed to sunlight.
The toxic effects of solanine are well-documented, although severe cases of solanine poisoning are rare. The Food and Drug Administration (FDA) limits solanine to 200-250 milligrams per kilogram of raw potato. However, it’s important to note that solanine affects individuals differently and some people may have lower tolerance for the toxin.
Consuming high levels of solanine can result in gastrointestinal symptoms like diarrhea, vomiting, abdominal pain, sweating, and headaches. The toxic dose of solanine is considered to be 1 mg or more per kilogram of body weight. While most cases of solanine poisoning resolve on their own, it is crucial to seek medical attention if symptoms persist or worsen.
Proper Storage And Preparation Of Potatoes
Proper storage is key in preventing potatoes from turning green and accumulating higher solanine levels. Storing potatoes in a cool and dark place with good air circulation, such as a pantry or drawer, will help maintain their freshness and quality.
When it comes to preparing green potatoes, there are ways to mitigate the solanine content. Peeling the potatoes can help reduce solanine levels, as it is primarily concentrated in the skin. Additionally, boiling potatoes can further decrease solanine, especially if the cooking water is discarded and not consumed.
However, it is important to note that cooking does not completely eliminate solanine from potatoes. Therefore, if a potato tastes bitter or causes a burning sensation, it is best to avoid consuming it. Discarding the green parts of the potato and not eating bitter-tasting potatoes is an effective way to reduce the risk of solanine poisoning.
While green potatoes may seem harmless or merely a cosmetic issue, they can indicate the presence of the toxin solanine. It is crucial to be aware of the potential health risks associated with consuming green potatoes and take necessary precautions. By properly storing potatoes, inspecting them before purchasing, and avoiding green or bitter-tasting potatoes, we can minimize the chances of solanine poisoning and enjoy this versatile tuber without worry.
