This low FODMAP smoothie is an adaptation of a SIBO friendly smoothie I’ve been living on recently. There’s something about the flavour combination that hits just right and it makes for a delicious low FODMAP and low fructose breakfast.

This smoothie uses frozen blueberries as the fruit and sweetness component of the smoothie. Some fat and protein content is added in the form of a nut butter (I like peanut butter here). Lactose free yoghurt provides creaminess and extra protein. There’s the option to add a low FODMAP protein powder to keep you fuller for longer. Finally, the smoothie is finished off with either a low FODMAP milk or plain old water. A simple recipe, but a truly delicious one.

This is a banana free smoothie, so no bananas here. Bananas do have a low FODMAP threshold, however, so I’m working on a low FODMAP smoothie with banana.

Are blueberries low FODMAP?

Yes, blueberries are low FODMAP. As of August 2026, Monash has stated that blueberries are low FODMAP in serves of up to 500g per person. This means you can well and truly enjoy fresh and frozen blueberries on the low FODMAP diet.

What kind of yoghurt is low FODMAP?

In Australia, there are a number of other lactose free yoghurts on the market. Sometimes I find that they have added chicory or inulin and some of them are quite thin. I can personally vouch for Chobant Fit which also has lactase added. Make sure you check the label before buying any new varieties of yoghurt. Lactose free yoghurt is low FODMAP in up to 500g serves.

Monash specifies that coconut yoghurt is low FODMAP in serves of up to 199g. In larger serves, coconut yoghurt contains moderate sorbitol.

Coconut yoghurt is the lowest FODMAP choice for a dairy free/vegan yoghurt option. Whatever you choose, be sure to read the labels to ensure they don’t contain any high FODMAP ingredients like chicory or inulin.

Which nut butters are low FODMAP?

Before we get into this, it’s worth noting that some nut butters could contain higher FODMAP ingredients. It’s best to buy a nut (or seed) butter that is just nuts and salt. All FODMAP quantities below as of August 2026.

Peanut butter is low FODMAP in 50g or 2 tablespoon serves. Interestingly, US peanut butter is written up as having a lower FODMAP threshold of 32g (2 tablespoons). This might be because Australian tablespoons are bigger than US tablespoons or because of a difference in the product. Monash doesn’t specify an upper limit.
FODMAP Friendly app says that peanut butter is low FODMAP in serves of up to 167g per person.
Almond butter is low FODMAP in up to 20g serves. In larger serves, it contains moderate GOS and fructans.
Macadamias are a low FODMAP nut. Although Monash don’t have a listing for macadamia nut butter specifically, 1-2 tablespoons should be a low FODMAP serve.
Pumpkin seeds (or pepitas) are low FODMAP in up to 81g serves per person. In larger serves, pumpkin seeds contain moderate amounts of fructans. I don’t know how many seeds make it into 1 tablespoon of nut butter, but I daresay 1 tablespoon of pumpkin seed butter would be low FODMAP.
I have written up a whole post on low FODMAP nuts and seeds here.

Substitutions for your low FODMAP smoothie

You can use frozen strawberries in place of the blueberries, if you’d prefer. Strawberries are low FODMAP in up to 74g serves. In larger serves, they contain moderate amounts of fructose. I don’t think they make for as creamy of a smoothie as blueberries, but they are an option.

Any low FODMAP nut or seed butter is appropriate here. They all have different flavours and will bring a new element to the smoothie. See the section above on low FODMAP nut butters.

If you’re vegan or have a preferred dairy free brand of yoghurt or milk, go for it! As long as it contains low FODMAP ingredients, it will work in your low FODMAP smoothie. If your yoghurt is particularly thin, however, use a little less milk or water to compensate.

Tips for this low FODMAP smoothie

Whey protein tends to become a little fluffy as it blends. I like it, but it’s just something to keep in mind.
When I use pure WPI (unflavoured) I like to add a pinch of stevia to sweeten things up a little.
Different protein powders will add different tastes. Some are sweetened and some plant proteins have a stronger taste. To make sure you’re using a low FODMAP one, see this post here.
If you like sweet smoothies, use a teaspoon or two of maple syrup. This recipe relies on the sweetness of the blueberries only.
Personally I like a thick smoothie, so I use 125- 185ml (1/2 – 3/4 Australian cup) milk. You can use anywhere from 125-250ml.
For a list of low FODMAP nuts, see this post here. I love peanut butter in this recipe.
A pinch of cinnamon or vanilla bean powder would be an excellent addition to this smoothie.
If you tolerate bananas, you could also use 1/2 a large (or a whole sugar banana) and 1/2 cup blueberries in this smoothie.
