Can you eat sprouted potatoes?


Potatoes are a versatile and widely consumed staple food in many parts of the world. However, what happens when your potatoes start to sprout? Is it safe to eat them or should you toss them out? In this article, we will delve into the topic of sprouted potatoes and provide you with detailed information on whether it is safe to eat them or not.

The Science behind Sprouted Potatoes

Before we dive into the safety aspect, it is important to understand why potatoes sprout in the first place. Potatoes are underground stems, also known as tubers, that store nutrients to support the growth of a new potato plant. When conditions are favorable, such as warmth and moisture, the dormant buds on the potato tuber start to grow, resulting in sprouts.

These sprouts, also called eyes, contain higher levels of certain compounds, including solanine and chaconine. These compounds are natural defenses that potatoes develop to protect themselves from pests and diseases. While solanine and chaconine are typically present in low levels in non-sprouted potatoes, their concentration increases as the sprouts grow.

Are Sprouted Potatoes Safe to Eat?

The safety of eating sprouted potatoes is a topic of debate among experts. Some argue that the increased levels of solanine and chaconine in sprouted potatoes can pose health risks, while others believe that consuming small amounts of sprouted potatoes is generally safe.

Potential Risks of Eating Sprouted Potatoes

One of the main concerns with sprouted potatoes is the potential toxicity of solanine. Solanine is a natural toxin that can cause symptoms such as nausea, vomiting, and diarrhea when consumed in large amounts. In extreme cases, it can even lead to more serious health issues.

However, it is worth noting that the concentration of solanine in sprouted potatoes can vary greatly depending on several factors, including the length of sprouting, storage conditions, and potato variety. While it is difficult to determine the exact solanine content of a sprouted potato, it is generally advised to minimize the consumption of potatoes with extensive sprouting.

Factors to Consider

When deciding whether to eat sprouted potatoes, there are several factors to consider:

Length of Sprouting

The longer a potato sprouts, the higher the concentration of solanine and chaconine. If your potatoes have just started sprouting and the sprouts are small, it is generally safe to remove the sprouts and consume the potato. However, if the sprouts are long and the potato has a wrinkled appearance, it is best to discard it.

Storage Conditions

The conditions in which potatoes are stored can also affect their sprouting and the accumulation of solanine. Potatoes stored in warm, humid environments are more likely to sprout and have higher levels of solanine. Proper storage in a cool, dark, and dry place can help slow down sprouting and reduce solanine formation.

Potato Variety

Not all potato varieties are created equal when it comes to sprouting and solanine content. Some varieties are more prone to sprouting and have higher levels of solanine even in non-sprouted potatoes. If you notice that a particular variety of potato consistently sprouts quickly, it may be best to avoid consuming sprouted ones from that variety.

The Truth About Sprouted Potatoes

How to Safely Consume Sprouted Potatoes

If you decide to eat sprouted potatoes, there are some precautions you can take to minimize the potential risks:

Remove the Sprouts

Before cooking or consuming sprouted potatoes, it is essential to remove the sprouts. The sprouts and any green parts of the potato should be cut off and discarded. The green color indicates the presence of chlorophyll, which is an indication of increased solanine levels.

Peel the Potatoes

Peeling the potatoes can further reduce the solanine content, as it is primarily concentrated in the skin and near the sprouts. However, keep in mind that some nutrients are also lost during peeling, so it is a trade-off.

Thoroughly Cook the Potatoes

Cooking potatoes at high temperatures can help break down solanine and reduce its toxicity. Boiling, baking, or frying the potatoes until they are fully cooked can minimize the potential health risks associated with sprouted potatoes.

Frequently Asked Questions (FAQs)

1. Can I eat potatoes with small sprouts?

Yes, it is generally safe to eat potatoes with small sprouts. Simply remove the sprouts and any green parts before consuming.

2. Can I eat potatoes if they have turned green?

Potatoes that have turned green should be avoided. The green color indicates the presence of chlorophyll, which is associated with increased solanine levels.

3. How can I prevent potatoes from sprouting?

Proper storage conditions are crucial for preventing sprouting. Store potatoes in a cool, dark, and dry place to minimize sprouting and the formation of solanine.

4. Are there any health benefits of sprouted potatoes?

Sprouted potatoes are not necessarily associated with specific health benefits. However, they do contain slightly higher levels of certain nutrients, such as vitamin C and antioxidants, compared to non-sprouted potatoes.

5. Can animals eat sprouted potatoes?

Sprouted potatoes should not be fed to animals, as they can also be affected by the increased solanine content. Consult with a veterinarian for appropriate pet feeding guidelines.

6. Can I plant sprouted potatoes in my garden?

Yes, sprouted potatoes can be planted in your garden to grow new potato plants. However, ensure that the sprouts are healthy and avoid planting potatoes with excessive sprouting or signs of decay.

7. Are there any alternative uses for sprouted potatoes?

Sprouted potatoes can be used for purposes other than consumption. They can be used to make compost or as a natural remedy for certain skin conditions due to their starch content.


In conclusion, while it is generally safe to eat sprouted potatoes with small sprouts, it is important to exercise caution and take necessary precautions. Removing the sprouts, peeling the potatoes, and thoroughly cooking them can help minimize the potential risks associated with increased solanine levels. However, for potatoes with extensive sprouting or a green color, it is best to err on the side of caution and discard them. Proper storage conditions can also help prevent sprouting and reduce the accumulation of solanine. As with any food, it is essential to use your judgment and prioritize food safety.
