According to the global food quality website, it was previously advised not to store potatoes in the refrigerator due to concerns about harmful substances. However, recent research has shown that there is only a negligible difference in the amount of toxic acrylamides and there is no problem with keeping potatoes in the refrigerator.
Potatoes should be stored in the dark to prevent the formation of toxic substances that can be harmful to human health. Light causes the formation of “protective” substances in potatoes, which are usually not visible on the surface. These substances, called “phytoalexins,” can be identified by the green color in the potato skin. When a potato is large, the green skin can be removed by peeling off a whole centimeter. Smaller potatoes with a green skin should be discarded.
In addition to storing potatoes in the dark, it’s recommended to keep them in a cool and dry place. A perforated plastic bag may not be adequately ventilated and can cause potatoes to rot quickly.
Potatoes contain a high amount of potassium, making it beneficial for those who have vomiting or diarrhea to consume them after these conditions to replenish any lost potassium from their bodies. Some minerals from potatoes may also pass into cooking water, so those who cannot eat due to vomiting or diarrhea can try drinking this water as well.
