1. Make sure they are firm
According to the National Capital Poison Center (an organization accredited by the American Association of Poison Control Centers), it is advisable to discard potatoes that have sprouted. As per studies, when potatoes sprout, their glycoalkaloid content begins to rise and excessive consumption of this compound is not good for the human body.
3. Avoid potatoes with green spots
4. Packaged potatoes are not healthy
If potatoes are packaged in a plastic bag, avoid buying such potatoes too, as there are chances they might have accumulated moisture and such potatoes might turn bad easily.
5. Avoid washing before storing
6. Store them in an open basket
Never store potatoes in closed baskets or poly bags. Ensure that they have a free flow of air. Also, keep them in a dry place to increase their shelf life.
