By keeping the skin intact or minimally peeling the tubers, you can further maximize their mineral retention.

It is important to note that different tubers may require different cooking methods and times.

It is recommended to research specific tuber varieties and their optimal cooking techniques to maximize mineral retention.

Additionally, considering the quality and freshness of the tubers is essential for obtaining the best nutritional value.

In a nutshell, cooking methods such as steaming, boiling, and roasting can help maximize mineral retention in tubers.

These techniques ensure that the valuable minerals present in tubers are preserved, making them a nutritious addition to the Nigerian diet.
