perhaps this is a better question,
is there any benefits from eating mangoes.
like would it be good to eat it pre workout?
something like that.
You'd be getting things from a mango as you would with most other common fruits.
Vitamins, fiber, polyphenols, antioxidants, simple carbohydrates. It would be good to eat the mango preW for some energy, more so if you're in some sort of hurry or if you have trouble finishing workouts fasted. So short answer, I suppose it would be "good'.
