Despite its “sweet” label, sweet potatoes can be eaten by diabetics because of their low glycemic index; meaning, eating a sweet potato does not cause a sudden spike in blood sugar levels.

Apart from being a staple crop, sweet potato is an important source of raw materials for the manufacture of starch, glucose and ethanol, and can also be used as a substitute for wheat flour in bread, as Nigeria uses cassava flour.

Cultivating sweet potato profitably requires loamy soil or good soil texture, adequate land clearing and preparation, appropriate plant population per hectare, application of manure or fertilizer if soil fertility is low and effective weed and pest control.
