The Claim

Added sugar intake induces gut inflammation, which increases luminal oxygen levels, thereby promoting the growth of oxygen-tolerant bacteria such as Enterobacteriaceae and Helicobacter while suppressing obligate anaerobes like Clostridium and Ruminococcus, resulting in a dysbiotic environment associated with metabolic disease.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

Eating too much added sugar can irritate your gut, making it more oxygen-rich, which helps bad bacteria thrive and hurts the good ones—this imbalance might contribute to metabolic problems like obesity or diabetes.

What the research says

1 study
  1. Study: Added sugars, gut microbiota, and host health

    Eating too much sugar can change the good bacteria in your gut, letting in bacteria that like oxygen and hurting the ones that don’t, which can lead to health problems like obesity and diabetes.
