Is Blueberry Banana Smoothie healthy?

Just bananas and blueberries are enough to call this creamy smoothie a health bomb.

Add oats – healthy breakfast staple, soy milk – full of calcium and protein, and lemon – immunity superhero, and you will get one of the healthiest snacks possible.

Key ingredients in Blueberry Banana Smoothie?


To make this smoothie extra creamy and add a little tang we will use vegan buttermilk instead of regular plant based milk. Buttermilk is actually made using vegan milk and lemon juice and it is ready in less than 5 minutes. Read this post to learn more about benefits and uses of vegan buttermilk.

SOY MILK works best if you want to obtain thick buttermilk, but you can use other plant milk if you have soy allergy.

LEMON juice will be used to curdle the milk and add a little tang to otherwise sweet ingredients. Not to mention all the health benefits, like boosting immune system and helping with weight loss.

Superhero of this smoothie recipe – blueberries are super tasty, super healthy and as a bonus they are responsible for this insanely pretty color. What not to like?

We should be earing berries on a regular basis, as they are very powerful antioxidants and they are great for our hearts.


What’s a smoothie without banana, right? They add texture, creaminess and sweetness. You can use frozen of fresh banana, preferably medium or very ripe.


Healthy breakfast staple – oats provide thick texture and they make the smoothie more substantial. You can soak them before blending for a smoother texture.


SWEETENER – If you like very sweet smoothies you can add maple of agave syrup. I noticed, if using ripe banana, I usually find smoothie sweet enough.

CHIA SEEDS – want to add even more nutritious goodness to this super healthy smoothie? Add a spoon of chia seeds.

How To Serve Blueberry Banana Smoothie?

The most important is – immediately. This smoothie is best served right after blending for a creamy, smooth texture. After a while it becomes thicker and jelly-like because of pectin in berries.

Serve it decorated with slices of banana and frozen berries. Banana Blueberry Smoothie is also perfect in a smoothie bowl.

Questions and Answers

Can I store Banana Blueberry Smoothie?

Because of blueberries, this smoothie is best when consumed right after blending. I do not recommend storing it for more than one hour. Blueberries are packed with pectin, that will eventually turn the smoothie into a jelly if you don’t drink it soon.

Can I Make Banana Blueberry nIce Cream?

Yes. This recipe is perfect also for ice cream. Use frozen berries and frozen bananas and half the amount of vegan buttermilk to make amazing vegan ice cream. You can freeze them for up to half an hour after blending for a firmer ice cream texture.

Can I Use Other Milk To Prepare Vegan Buttermilk?

If for any reason you don’t want to use soy milk, you can use other type of plant based milk. Your buttermilk will not be as thick as when using soy milk though. Please check this article about making and using vegan buttermilk for more information.

Can I Use Other Berries?

Sure, you can use Strawberries, Raspberries or Blackberries. They will all work fine in this recipe. It’s best to use frozen berries.
