You are missing the point.
Of the FRUIT WORLD.
It was not about actual calories, fat, carbs, protein and all that crap content.
It was compared to other fruits, since when does other fruit has salt, addictive.
As for taste, that is subjective....i know people who think it taste like glue. I know people who think it tastes furry. I know people think won't touch it because it is radioactive. (seriously)
Don't mention other fruits because no other fruits has addictive.
It was merely a metaphor, you do know what that means right ?
There is no need to be patronizing, I know exactly what he meant but he was just plain wrong. McDonalds is about the worst burger you can buy, Bananas are definitely not the worst fruit you can buy. E.g. compared to say Blueberries it has far more potassium, magnesium, Vit B6, similar fiber and vit C and sugars, and the same lack of protein.
Things like grapes and water melon have far lower fiber, vitamins, minerals and higher sugar content. Even compared to an orange a Banana has far more vitamins, minerals -just way less Vit C.
So no, a Banana is great
