Health Benefits Of Bananas


Bananas are fruits that typically grow in warm weather or equatorial regions. They are tropical fruits, but people consume and enjoy them worldwide. Bananas are from the genus Musa from the Musaceae family according to the botanical classification. It is a flowering plant with lots of varieties.
