Bananas are rich sources of fast-acting carbohydrates, meaning they quickly convert into sugars the body uses as fuel. They also contain plenty of potassium, a nutrient that keeps the nerves and muscles functioning well.
Fitness magazine suggests eating sliced banana on a piece of whole-wheat toast with a dash of cinnamon. The source says this pre-workout snack combination provides the body with both types of carbohydrates: simple (from the banana, a quick kick of energy) and complex (from the bread, which helps to sustain energy levels). And the cinnamon isn’t just for added flavor; the spice “has been linked to stabilizing blood sugar and improving brain function.”
