The Claim
High intake of added sugars, particularly from liquid sources such as sugar-sweetened beverages, is associated with altered gut microbiota composition, including enrichment of sugar-utilizing bacteria such as Enterobacteriaceae and Blautia, and depletion of short-chain fatty acid-producing taxa such as Ruminococcus and Lachnospira, which may contribute to impaired gut barrier function and systemic inflammation linked to metabolic diseases.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Eating a lot of added sugar, especially in sodas and sweet drinks, might change the good bacteria in your gut, letting some bacteria that love sugar grow too much while reducing others that help keep your gut healthy—this could lead to leaks in your gut lining and inflammation that’s tied to diseases like diabetes.

What the research says
1 studyStudy: Added sugars, gut microbiota, and host health
Eating too much sugar, especially in drinks, can change the good bacteria in your gut, making some that like sugar grow more and others that help your gut health shrink. This can hurt your gut lining and cause inflammation, which might lead to diseases like obesity or diabetes.
