Healthy Banana Smoothie Recipe for Diabetics
The controversy around a banana's glycemic index made me reluctant to try it in a smoothie, but this recipe works, and it works well.
It has only half of a banana per serving - that's about half of a cup of sliced banana.
The banana is the main source of carbs here, amounting to 13.5g per serving.
Recipe Substitutions
Milk
I used Unsweetend Vanilla Almond Milk. That's what I have on hand at all times, but any low-carb milk would work as a substitute.
I do not recommend using water as the liquid substitute because it would dilute the flavor too much.
Adding Protein Powders
This smoothie recipe is low in protein. You can add a protein powder but it'll significantly change three things: consistency, flavor and carb count.
Consistency
The consistency of this smoothie is already perfect in my opinion. Adding a powder would thicken it to the point that you'd have to thin it out with a bit of milk or water. But If you're a thick smoothie person, great!
Flavor
Depending on the protein powder you use, the flavor will change, and if your protein powder doesn't have a sweetener included, the sweetness of this smoothie will noticeably decrease.
Carbs
Most protein powders have about 15g carbs per serving, but some are below 10g carbs.
Nutritious Additions
If you're used to less sweet smoothies, throw in ½ cup of baby spinach. It doesn't alter the taste (it just brings down the sweetness a bit), but it adds nutrition.
Note - When adding baby spinach to a smoothie, blend on high until there are no more visible pieces of spinach. It may take over 1 minute to achieve, but the spinach will incorporate fully.
Hulled hemp seeds are also a great addition because they are a low carb protein.
The one thing to consider with hemp seeds is that they add texture to the smoothie. If you don't want to chew on your smoothie (like, if you're the person that can't stand any pulp in your orange juice), or if texture may trigger your gag reflex, don't add them.
Batching
You can double this recipe if you want, but it's so simple you probably won't even need to.
Any servings that you don't drink immediately should be stored in the refrigerator until you're ready to drink them.
Give stored servings a quick shake or blend just before drinking due to a little water separation.
Storing
Store in the refrigerator for up to 2 days. Shake or stir just before drinking.

This was so so sooooo delicious! Love the whippy texture the avocado gives- the mouthfeel is like a thick shake. Had it as my bedtime snack and it hit the banana cravings!

Interesting you can have it before bedtime. I’m not allowed fruit before bed (dr recommended during gestational diabetes)

Hi Anon! If I had to guess, I would think that the person who has this as a bedtime treat was maybe just looking for a low carb smoothie, and not necessarily diabetic. I say that because this smoothie doesn't have a great balance of macronutrients. Or, maybe they paired it with a protein and didn't mention it. - Traci

I love this smoothie - I need to get it to keeonme till lunchtime. Can I use a whole avacado and 1/2 cup yogurt? I’m type 2 .
The Gestational Diabetic Chef
Hi Cath! I'm glad you loved the smoothie. You can definitely use a whole avocado, but it'll thicken and be less sweet, so you may want to use a bit more milk (by eye) to thin it out to your liking. For the sweetness, sometimes I add a couple drops of liquid stevia. Works great every time!
Jenny
Sorry this was not tasty. Lumpy and not sweet at all.
The Gestational Diabetic Chef
Hi Jenny, I'm sorry you didn't have success with this recipe. About the lumps, my guess is that either your avocado wasn't ripe enough, or you didn't blend long enough or at a high enough speed. I'll be sure to edit the post to add these notes. A smoothie definitely shouldn't be chunky, lol. As for the sweetness, you can add a bit of liquid stevia or more banana if you can handle the carbs.
Carol
perfectly sweet. Great bedtime treat for me.
The Gestational Diabetic Chef
Totally agree! I make it 2 to 4 times a week. It really is just perfect. Sometimes I add a bit of liquid stevia.
