Potatoes are one of the most widely consumed staple foods globally, and it’s not uncommon to come across a potato with eyes or sprouts. While some people might be tempted to eat these potatoes, others might be hesitant due to concerns about safety and potential health risks. In this article, we’ll delve into the world of potatoes with eyes, exploring what happens when you eat them, and separating fact from fiction.
What are Potato Eyes, and Why Do They Form?
Potato eyes are the small, bud-like structures found on the surface of potatoes. They are actually the nodes from which new potato plants can grow. These eyes can form on any part of the potato, but they are more commonly found on the ends or near the surface.
Potato eyes form as a natural part of the potato’s life cycle. When a potato is mature and ready to be harvested, the eyes begin to sprout, signaling the start of a new growth cycle. This process is triggered by the production of hormones, such as auxins and gibberellins, which stimulate cell division and elongation.
Why Do Potatoes with Eyes Sprout?
Potatoes with eyes can sprout for several reasons:
- Light exposure: Potatoes exposed to light, especially in the visible spectrum, can stimulate the production of chlorophyll and the growth of sprouts.
- Temperature fluctuations: Changes in temperature can trigger the growth of sprouts. Potatoes stored at temperatures between 40°F and 50°F (4°C and 10°C) are more likely to sprout.
- Moisture: High humidity and moisture can contribute to the growth of sprouts.
- Ethylene production: Potatoes, like many fruits and vegetables, produce ethylene gas as they age. This gas can stimulate the growth of sprouts.
Are Potatoes with Eyes Safe to Eat?
The safety of eating potatoes with eyes is a topic of debate. While some people claim that potatoes with eyes are toxic, others argue that they are perfectly safe to eat. The truth lies somewhere in between.
Potatoes with eyes contain a toxic compound called solanine, which is produced by the plant as a natural defense mechanism. Solanine is a glycoalkaloid that can be toxic to humans if consumed in large quantities.
However, the amount of solanine present in a potato with eyes is generally not enough to cause harm. In fact, the US Department of Agriculture (USDA) states that potatoes with eyes are safe to eat as long as they are cooked properly.
Cooking and Solanine Reduction
Cooking potatoes with eyes can reduce the amount of solanine present. Heat can break down the glycoalkaloid, making it less toxic. However, it’s essential to cook the potatoes thoroughly to ensure that the solanine is reduced to safe levels.
Here are some tips for cooking potatoes with eyes:
- Boiling: Boiling potatoes with eyes can reduce the amount of solanine by up to 30%.
- Baking: Baking potatoes with eyes can reduce the amount of solanine by up to 20%.
- Frying: Frying potatoes with eyes can reduce the amount of solanine by up to 10%.
Health Risks Associated with Eating Potatoes with Eyes
While the amount of solanine present in a potato with eyes is generally not enough to cause harm, there are some potential health risks associated with eating these potatoes.
- Gastrointestinal symptoms: Eating potatoes with eyes can cause gastrointestinal symptoms, such as nausea, vomiting, and diarrhea, in some individuals.
- Allergic reactions: Some people may be allergic to solanine, which can cause an allergic reaction, including hives, itching, and difficulty breathing.
- Interaction with medications: Solanine can interact with certain medications, such as blood thinners and diabetes medications, which can lead to adverse effects.
Who Should Avoid Eating Potatoes with Eyes?
While potatoes with eyes are generally safe to eat, there are certain individuals who should avoid them:
- Pregnant women: Pregnant women should avoid eating potatoes with eyes due to the potential risk of solanine toxicity.
- Children: Children should avoid eating potatoes with eyes due to their smaller body size and potential sensitivity to solanine.
- People with compromised immune systems: Individuals with compromised immune systems, such as those with HIV/AIDS or undergoing chemotherapy, should avoid eating potatoes with eyes due to the potential risk of infection.
Conclusion
Eating a potato with eyes is not necessarily a cause for concern. While these potatoes do contain a toxic compound called solanine, the amount present is generally not enough to cause harm. However, it’s essential to cook the potatoes thoroughly to reduce the amount of solanine present.
If you’re concerned about the safety of eating potatoes with eyes, it’s always best to err on the side of caution. Remove the eyes and any sprouts before cooking, and cook the potatoes thoroughly to ensure that they are safe to eat.
By understanding what happens when you eat a potato with eyes, you can make informed decisions about your diet and enjoy this nutritious and delicious food with confidence.

What are the “eyes” on a potato, and are they safe to eat?
The “eyes” on a potato are actually the nodes from which new potato plants can grow. They are a natural part of the potato and consist of a bud and a small amount of stem tissue. While it’s technically possible to eat the eyes, it’s generally not recommended. This is because the eyes can produce toxic compounds called glycoalkaloids, which can be harmful if ingested in large quantities.
However, it’s worth noting that the glycoalkaloids are not unique to the eyes and are present throughout the potato. The amounts are generally highest in the eyes, sprouts, and green skin, but they can be found in smaller amounts in the rest of the potato as well. To minimize exposure, it’s a good idea to remove the eyes and any sprouts before eating a potato, and to avoid eating green or damaged potatoes.
Can eating a potato with eyes make you sick?
Eating a potato with eyes is unlikely to make you seriously ill, but it can cause some unpleasant symptoms. The glycoalkaloids present in the eyes can cause nausea, vomiting, diarrhea, and stomach cramps if ingested in large quantities. However, the amounts present in a single potato are generally not enough to cause severe symptoms.
That being said, some people may be more sensitive to the glycoalkaloids than others, and eating a potato with eyes can exacerbate underlying health conditions. For example, people with digestive issues or compromised immune systems may be more susceptible to the negative effects of glycoalkaloids. To be on the safe side, it’s best to err on the side of caution and remove the eyes before eating a potato.
How do glycoalkaloids form in potatoes, and can they be removed?
Glycoalkaloids are naturally occurring compounds that form in potatoes as a defense mechanism against pests and diseases. They are produced in response to stress, injury, or infection, and can be triggered by factors such as light, temperature, and moisture. While it’s not possible to completely remove glycoalkaloids from a potato, you can minimize their formation by storing potatoes in a cool, dark place and avoiding damage or injury to the tubers.
You can also reduce the amounts of glycoalkaloids in a potato by removing the eyes, sprouts, and green skin, as these are the areas where the compounds tend to concentrate. Cooking potatoes can also help to break down some of the glycoalkaloids, although it’s not a foolproof method. To be on the safe side, it’s best to combine multiple methods, such as removing the eyes and cooking the potatoes, to minimize exposure to glycoalkaloids.
Are all potatoes created equal when it comes to glycoalkaloids?
No, not all potatoes are created equal when it comes to glycoalkaloids. Some varieties of potatoes tend to produce more glycoalkaloids than others, and factors such as growing conditions, maturity, and storage can also affect the levels of these compounds. For example, potatoes that are grown in cooler, more stressful conditions may produce more glycoalkaloids than those grown in warmer, more favorable conditions.
In general, it’s a good idea to choose potatoes that are high in starch and low in moisture, as these tend to have lower levels of glycoalkaloids. You can also look for varieties that are specifically bred to be low in glycoalkaloids, such as Russet or Idaho potatoes. However, it’s worth noting that even within a given variety, there can be significant variation in glycoalkaloid levels, so it’s always a good idea to err on the side of caution and remove the eyes and any sprouts before eating.
Can you die from eating a potato with eyes?
It is highly unlikely that you would die from eating a potato with eyes. While the glycoalkaloids present in the eyes can cause unpleasant symptoms, the amounts present in a single potato are generally not enough to cause severe or life-threatening illness. In fact, you would need to eat a very large quantity of potatoes with eyes to ingest a toxic amount of glycoalkaloids.
That being said, there have been some reported cases of people experiencing severe symptoms, including hallucinations, paralysis, and even death, after eating large quantities of green or sprouted potatoes. However, these cases are extremely rare and usually involve other factors, such as underlying health conditions or the presence of other toxins. To be on the safe side, it’s best to err on the side of caution and avoid eating potatoes with eyes or any other signs of spoilage.
How can you safely store potatoes to minimize glycoalkaloid formation?
To minimize glycoalkaloid formation, it’s best to store potatoes in a cool, dark place with good ventilation. The ideal storage conditions are a temperature between 40°F and 50°F (4°C and 10°C), and a relative humidity of 80-90%. You should also avoid storing potatoes in direct sunlight or near a heat source, as this can trigger the formation of glycoalkaloids.
It’s also a good idea to store potatoes in a breathable container, such as a paper bag or a mesh bag, to allow for airflow and moisture transfer. Avoid storing potatoes in airtight containers or plastic bags, as this can create a humid environment that fosters glycoalkaloid formation. Finally, check on your stored potatoes regularly to remove any that are showing signs of spoilage or sprouting.
Can you eat potato sprouts, and are they safe?
It’s generally not recommended to eat potato sprouts, as they can contain high levels of glycoalkaloids. While the sprouts themselves are not toxic, they can produce toxic compounds as they grow, which can be harmful if ingested. In fact, potato sprouts can contain up to 100 times more glycoalkaloids than the rest of the potato.
If you notice that your potatoes are sprouting, it’s best to remove the sprouts and any affected areas before eating the potato. You can also try to prevent sprouting by storing potatoes in a cool, dark place and avoiding damage or injury to the tubers. If you’re looking to grow your own potatoes, you can also try using certified disease-free seed potatoes, which are less likely to produce sprouts or glycoalkaloids.
