Health Benefits of Bananas
Bananas are one of the most popular snack fruits in the world, and for good reason. They’re not only extremely portable and convenient to eat without getting messy (digging your teeth into a juicy peach sounds tempting, but let’s face it – it does come with its own share of mess), but good for you too.
One medium sized banana has a fair amount of dietary fibre, is high in vitamin B6, manganese, copper and magnesium. You can read more about the health benefits of bananas here.
Health Benefits of Peanut Butter
Fats should be a part of every healthy diet. You just need to choose wisely.
Peanut butter contains mono-saturated fat (a good guy), is packed with protein, fibre and useful vitamins, potassium (helps your kidneys to filter blood) and magnesium (great for bone health). You can read more about the different types of fat here.
Variations
- Swap the nut butter – you can easily make a peanut-allergy friendly variation of this smoothie by using a different nut butter. Almond butter is the perfect substitute.
- Make it sweeter – while bananas already add plenty of sweetness, you can make the smoothie even sweeter by adding a teaspoon of honey or agave syrup.
- Use milk of choice – both dairy milk and plant-based varieties all work really well in this smoothie, including soy milk, hemp milk, coconut milk, and my favourite, almond milk.
- Add some toppings – a swirl of nut butter, sliced bananas, chopped nuts and a drizzle of honey can take this smoothie to the next level.
