People who underwent stem-cell transplantation and ate sugar-rich food had disrupted communities of gut microorganisms during antibiotic treatment, according to a study published in Nature on 30 September 2026. The research by Dai et al. shows diet can influence the severity of antibiotic-induced microbial disturbance. The findings highlight a potential dietary factor in managing gut health during antibiotic therapy.

Key Facts

The study was published in Nature on 30 September 2026.

Study Findings

Writing in Nature, Dai et al. report that diet can influence the severity of antibiotic-induced gut microbial disturbance. The study focused on people who underwent stem-cell transplantation and ate sugar-rich food. These individuals had disrupted communities of gut microorganisms during antibiotic treatment.

Clinical Implications

Antibiotics are often crucial therapies, but their use comes at the expense of a person’s gut microbial community. The findings suggest that dietary choices, particularly sugar intake, may affect the extent of microbial disruption during antibiotic therapy. This could have implications for managing gut health in patients undergoing stem-cell transplantation.
