Yuca is a root vegetable that is cultivated and harvested in tropical and subtropical regions. Its name is pronounced "yoo-kah." Depending on where it is farmed, it goes by many different names, including tapioca, manihoc, and cassava. 
The vitamin C content of yuca root is quite high, providing up to a third of an adult's daily needs in only one serving. Vitamin C is a crucial part of your blood vessels and muscles and aids in your body's ability to recover from damage. Regularly consuming adequate vitamin C can also help strengthen your immune system.
