According to recent research, it is now safe to store potatoes in the refrigerator. However, in the past, it was not advisable due to concerns about toxic substances formed by acrylamides. Today, there is little difference in the amount of these substances between refrigerated and non-refrigerated storage.
Potatoes should be stored in a cool and dry place away from light to prevent the formation of toxic substances known as “phytoalexins.” These substances can be identified by their green color on the skin of the potato. For larger potatoes with a green skin, simply peel off a whole centimeter. Smaller potatoes with a green skin should be discarded.
It’s also important to keep potatoes dry and well-ventilated. Using a perforated plastic bag for storage is not ideal as it can cause potatoes to rot quickly due to lack of air circulation.
Potatoes are high in potassium and can help replenish this mineral lost from the body after vomiting or diarrhea. Some of the minerals in potatoes may pass into cooking water, so those who cannot eat them due to illness can try drinking the water used for cooking them as an alternative source of nutrients.
