Banana is used as a base for many commercial smoothies as it acts as both a sweetener and a thickener, which means you won’t have to add either of these unless you want to (they also use it commercially because it’s cheaper than many other fruits, which might be a consideration for you too).
Bananas are also a great source of minerals such as potassium, and they release their energy more slowly than other fruits, so you don’t get the sugar “dump” you can get with some smoothies.
Having said that, if you can, use well-ripened bananas as more of the starch has turned to sugar in these, which makes them sweeter and also more easily digestible – so you feel full but not bloated.
Bananas have quite a strong flavor, so combining them with another distinctive flavor (in this case peanut butter) means that you won’t only get the single flavor of banana.
o 1 large ripe banana
o 4tsp of peanut butter (unsalted)
o 1½ cups of milk
Put all the ingredients in the blender and turn on. Blend until smooth. You can adjust the thickness by adding ice if you want to thicken it, then pulsing the blender, or add more milk to thin it down.
