Healthy Blueberry Banana Smoothie

This nourishingly healthy blueberry banana smoothie is a great way to start your day or to enjoy as a healthy post-workout snack at any time of day.  It’s deliciously creamy and oh so nutritious.  You can use fresh or frozen blueberries and bananas. 

The secret to this smoothie is in the combination of blueberries, bananas and oats.  All three ingredients have a low to medium GI index meaning you’ll feel fuller for longer so you’ll resist the temptation to snack between meals.

The quantities can easily be halved or doubled. 

Blueberry Banana Smoothie Ingredients


I can’t work out if it’s the purple pop of vibrancy or the lusciously sweet flavour of blueberries that make them so appealing.  Maybe it’s the high nutritional value that keeps me coming back for more!  Whatever it is, I just can’t get enough of these little jewels of juiciness. 

Blueberries have been brandished as a Superfood for quite some time now.  Studies show that they contain antioxidants to help reduce the risk of heart disease, they help protect the immune system and are also known to contain flavoids to help reduce inflammation.

Enjoy them as a healthy snack on their own or add them to muffins and flapjacks for a pop of colour and flavour.  Alternatively, enjoy them as a topper for oats, smoothie bowls and yoghurt.  I love the sweet flavour of freshly picked blueberries, but with such a short (not to mention hit and miss) season for us Brits, I’m glad to say they retain all the flavour and shape when I buy them frozen. 


At around 105 calories, bananas are a convenient ‘on the go’ snack just on their own.  Equally, they are a great topper for oats and smoothie bowls as well as a flavourful and nutritious addition to smoothies.  They make great low-sugar muffins and cookies too as much of the refined sugar can be replaced by the addition of over-ripened bananas.

I’ve recently discovered that freezing bananas is a great way to avoid bruised or over-ripe and brown bananas.  Just peel and chop into bite-sized chunks, lay on a sheet in your freezer and allow to freeze for 2-3 hours.  Afterwards, you can conveniently store them in plastic bags or airtight containers until needed. 

Flax Seeds

I find using ground flax seeds are best for making smoothies.  Whilst the whole seeds can offer texture and a slight crunch and are a good topping for a smoothie bowl, they are not easily digested and they don’t blend particularly well. 

Flax seed are low in calories, a good source of protein and are high in fibre.  As protein-rich foods can supress appetite, eating flax seeds are said to support weight loss efforts.   


Oats contain soluble fibre which is known to help slow digestion, suppress appetite and give the feeling of being full for longer.  Oats also contain plant chemicals that act as antioxidants that help to reduce inflammation and decrease the risk of heart disease and diabetes. 

When I first started making smoothies a Blueberry Banana Oatmeal Smoothie was pretty much my go to and I refer back to this recipe probably weekly because I know that it’s one my whole family will enjoy. 

Watching everyone enjoy this smoothie makes me feel assured that we are all set up for the day with sustained energy and a good dose of nutrients.

I hope that you enjoy it as much as we do.

Blueberry Banana Smoothie Recipe Variations

Blueberry Banana Spinach Smoothie

Eye health, heart health, skin and hair growth and bone strength are just some of the great reasons to cram as much spinach into your diet as possible.  Adding a handful of spinach to the rest of the ingredients in this recipe will do just that.

Spinach is known to contain carotene and chlorophyll.  These are antioxidants and are known not only to slow the ageing process but also help maintain a healthy immune system making our bodies better equipped to repel viruses and bacteria.  Spinach also contains magnesium and folate, both of which are nutrients that help your body create energy to keep you going throughout the day.

Blueberry Banana Smoothie Without Yogurt

I’ve left the option to use Greek yoghurt up to you in this one.  Personally, I don’t think you need Greek yoghurt especially if you use frozen blueberries and frozen banana to make the smoothie.  The use of frozen fruit offers a wonderful creaminess anyway. 

Of course, if you are preparing this for a plant-based diet then you should leave out the Greek yoghurt altogether or replace it with almond or coconut yoghurt.

Peanut Butter Banana Blueberry Smoothie

The addition of peanut butter provides a creamy, nutty flavour to compliment the banana and blueberry perfectly.  I would suggest adding 2 tablespoons of the smooth variety and opt for a good quality clean peanut butter.  Peanut butter has the highest amount of protein gram for gram versus other nut butters.  It is low in carbs and high in antioxidants. 

If the addition of a nut butter has whetted your appetite but you are catering for intolerances or dietary restrictions then there are other delicious nut butters readily available in delicatessens and supermarkets.  Cashew and almond butter are easiest to get hold of here in the UK. 

Of course, if nut butter is not an option then perhaps consider sesame seed butter or tahini.

Blueberry Banana Smoothie Ingredient Substitutes

Milk Alternatives – Banana Blueberry Smoothie with Almond Milk

The use of almond milk means this smoothie is dairy-free and vegan – providing you leave out the optional suggestion of Greek yoghurt.  Another dairy-free milk option that tastes great in this smoothie is oat milk.  Oat milk is just as delicious and has a similar consistency to almond milk and so it’s a good alternative if you don’t have almond milk or are diet-restricted.

If your diet is unrestricted, then of course, dairy would also taste great. 

Adding Avocado – Avocado Blueberry Banana Smoothie

Avocados add a wonderfully creamy texture and don’t really have much of a taste.  This is great news if you love the sweetness of bananas and blueberries and want to add more nutrition to your smoothie. 

It’s no wonder that avocados are enjoying a popularity surge!  Each avocado fruit contains no less than 20 different vitamins and minerals.  This makes avocados one of the most nutritious fruits on the planet.  They are loaded with potassium and healthy fats (oleic acid which is a monounsaturated fat) both of which are known for promoting heart health by lowering the risk of stroke and reducing blood pressure.  They are also rich in fiber and low in carbs which may help with weight loss as they make you feel fuller for longer.
