According to the global food quality website, it was previously advised not to store potatoes in the refrigerator. However, recent research has shown that there is little difference in the amount of toxic acrylamides when potatoes are stored in the refrigerator or at room temperature. Therefore, keeping potatoes in the refrigerator is now considered safe.
Potatoes should be stored in a cool and dry place, away from light. When potatoes are exposed to light, they produce “protective” substances that can cause harm to human health. These substances are called “phytoalexins,” which can be identified by their green color on the skin of the potato. Large potatoes with a green skin can be peeled to remove these harmful substances, while smaller potatoes with a green skin should be discarded entirely.
In addition to storing potatoes in a cool and dry place, it is also important to use perforated plastic bags for proper ventilation. Without proper ventilation, potatoes can rot quickly and become unusable for consumption.
Potatoes are rich in potassium, making them an excellent option for replenishing this mineral after vomiting or diarrhea. Some of the minerals in potatoes pass into cooking water, so those who cannot eat due to these conditions can try drinking the water used to cook them instead.
