Other Names:  

It is a species of hickory, native to Mississippi.  A pecan, like the fruit of all other members of the hickory genus, is not truly a nut, but is technically a drupe, a fruit with a single stone or pit, surrounded by a husk. The buttery-rich kernel is golden-brown on the outside and beige inside.

Commonly used in:  
They can be eaten fresh or used in cooking, particularly in sweet desserts, but also in some savory dishes.

Health Benefits: 
Pecans are a good source of protein and unsaturated fats. Like walnuts (which pecans resemble), pecans are rich in omega-6 fatty acids, although pecans contain about half as much omega-6 as walnuts.  A diet rich in seeds can lower the risk of gallstones in women.  The antioxidants and plant 
sterols found in pecans reduce high cholesterol by reducing the "bad" LDL cholesterol levels.
