When potatoes start sprouting, they might look strange, but they are generally safe to eat if the sprouts are minimal.

However, these sprouts contain solanine, a toxin that can cause issues like headaches, nausea, and digestive discomfort. If large amounts of solanine are consumed, symptoms can become more severe.

According to Ellen Shumaker, a food safety expert at North Carolina State University, potatoes with small sprouts can be salvaged by trimming off the sprouts, as long as the potato remains firm and hasn’t shriveled. Soft or wrinkled potatoes, however, should be discarded.

Green Potatoes: A Warning Sign

Potatoes exposed to sunlight can develop a greenish tint, indicating the production of chlorophyll and the build-up of solanine. Unlike other green vegetables, green potatoes can be harmful. Dietitian Maggie Michalczyk warns that potatoes with large green areas are best avoided entirely. Small green spots can be trimmed off, but potatoes with significant greening should not be consumed.

Shumaker adds that green potatoes and sprouting ones share similar risks. Beyond the potential for digestive discomfort, solanine in severe cases can have more serious effects.

Impact on Flavor and Nutrition

Potatoes that have started to turn green or sprout don’t just pose a safety concern; their taste and nutritional value are also affected. These potatoes can develop a bitter flavor and may lose some of their nutrients due to oxidation.

Tamar Samuels, a registered dietitian, notes that sprouted potatoes are likely less nutritious than fresh ones. Still, normal potatoes, whether sweet or white, are excellent sources of essential vitamins and minerals. White potatoes provide potassium and vitamin C, while sweet potatoes are rich in vitamin A due to their vibrant orange hue.

Tips for Keeping Potatoes Fresh

To keep your potatoes safe and fresh for longer, store them in a cool, dry, and dark place. A paper bag can help shield them from sunlight, reducing the risk of greening and sprouting. Proper storage not only prevents spoilage but also ensures that your potatoes retain their nutrients and flavor.

Potatoes have played an important role in history, even aiding in the prevention of certain deficiencies due to their high vitamin C content. By handling and storing them properly, you can continue to enjoy their benefits without concerns.

So, next time you’re preparing a hearty potato dish, make sure to check for any signs of sprouting or greening. Enjoy fresh, firm potatoes and savor their natural goodness!
