The Juicing Deception: Why Your Gut Hates It

10 minutes

Story at-a-glance

A study in the journal Nutrients examined how juicing affects gut and oral microbiomes, finding that removing fiber significantly decreases beneficial microbial diversity and increases inflammation-linked bacteria
Participants who consumed whole foods with higher fiber showed increased beneficial microbes that protect gut lining and reduce inflammation, while the juice-only group experienced negative microbial changes within three weeks
Removing fiber through juicing disrupts SCFA (short-chain fatty acid) production and weakens gut barrier integrity, which can lead to leaky gut syndrome where harmful substances enter the bloodstream
The oral microbiome is particularly susceptible to rapid changes from juicing, as the sudden increase in simple sugars without fiber's buffering effects promotes harmful bacterial growth
Instead of juicing, consider eating whole fruits and vegetables, blending produce to retain fiber, adding pulp to juices and gradually increasing fiber intake to support your gut microbiome
