How many bananas is to many for two days?

There'sBetterChoices: There's a formula for that but it involves advanced calculus and a degree in nanotechnology.But before using that formula we need to know any reason or need for more than,say,two bananas a day,with the exception of a recently purchased blender and a penchant for banana smoothies.Bananas are starchy, high sugar(200cal a piece)6gm fiber(pretty good)with some vitamins and minerals thrown in.Whoo Hoo!
