However, while cassava offers nutritional benefits, it also requires careful preparation to ensure safety. The root naturally contains compounds called cyanogenic glucosides, which can release trace amounts of cyanide if not properly processed.

In rare cases where cassava has not been adequately processed, it may contribute to health challenges. One such concern is a neurological condition known as konzo, which has been observed in certain communities where protein intake is low and bitter varieties of cassava are consumed without proper preparation.
