Overview
About Smoothie
Do smoothies cause bloating, and does blending remove FODMAPs?
A smoothie is only as gentle as what goes in it, and the catch is concentration: blending several fruits into one glass stacks fructose, fructans, polyols and oxalate that you would rarely eat whole in a single sitting. Blending breaks the cells but leaves every FODMAP molecule intact.

Watch for
What trips people up
- Blending does not remove FODMAPs: it breaks up cells but the fructose, fructans and polyols stay in the glass, so a smoothie is not gentler than the whole fruit
- Stacking works against you: one smoothie can blend several fruits at once, concentrating a moderate FODMAP, salicylate and oxalate load you would not eat whole in one sitting
- Depending on the mix it can also carry moderate histamine and tyramine, especially from banana, citrus or blended fruit left to sit
- As a sweet, fruit-heavy drink it rates poorly for SIBO; portion and single-fruit control are what bring it back down

FAQ
Common questions about Smoothie
Does blending remove FODMAPs?
No. Blending ruptures the fruit cells but leaves the fructose, fructans and polyols intact, so a smoothie is no lower in FODMAPs than the fruit it is made from. If anything, you tend to drink more fruit at once than you would eat whole.
Why do healthy smoothies cause bloating?
Because they stack triggers. Combining several fruits, and often spinach or other add-ins, concentrates a moderate FODMAP, salicylate and oxalate load into one glass, which is more than most sensitive guts would meet in a single whole-food snack.
Can I make a low-FODMAP smoothie?
Yes, by not stacking. Build it on one low-FODMAP fruit in a controlled portion, skip the high-FODMAP add-ins, and it comes down considerably from the moderate load a mixed-fruit smoothie carries.
