The Claim

Higher consumption of sugar-sweetened beverages is associated with lower exhaled breath hydrogen and elevated salivary IL-6 levels in adults.

In plain English

Adults who drink more sugar-sweetened beverages have lower levels of exhaled breath hydrogen and higher levels of the inflammatory marker IL-6 in saliva.

See the scientific wording

Higher consumption of sugar-sweetened beverages is associated with lower exhaled breath hydrogen and elevated salivary IL-6 levels in adults, indicating altered gut microbial fermentation and increased inflammation.

Why this might work

Too much sugar in drinks feeds bacteria that produce less hydrogen gas and more harmful byproducts, which irritate the gut lining and cause immune cells to release inflammation markers into the saliva.

What the research says

1 study

  1. Study: Link between ultra-processed foods and drinks intake, gut microbiota and inflammation: an exploratory analysis in adult volunteers.

    This study found that people who drank more sugary beverages had less hydrogen gas in their breath (which means their gut bacteria were acting differently) and more of an inflammation marker in their saliva. So yes, drinking more sugary drinks is linked to these changes.
