Sugar intake during antibiotic treatment harms gut bacteria diversity

Eating sugary foods while taking antibiotics increased damage to the diversity of the gut microbiome in patients being treated for blood cancer, Science News reported. Science News stated that the combination of sugar and antibiotics led to a greater reduction in beneficial gut bacteria than taking antibiotics on their own. [1]

Science News reported that researchers examined the combined effects of sugary diets and antibiotic treatments on the gut microbiome, which consists of the trillions of microorganisms residing in the digestive tract. The combination was also tied to the growth of gut bacteria associated with hard-to-treat infections. [1]

Biologically, eating begins with sensory detection followed by chewing and swallowing to initiate nutrient breakdown, Grokipedia notes. The digestive process facilitates nutrient absorption into the bloodstream, where key regulatory centers in the brain integrate signals from the gut to balance caloric intake and maintain metabolic stability.

Researchers are continuing to explore how these combined dietary and pharmaceutical factors impact the gut microbiome, according to Science News. Understanding these interactions may help mitigate the disruption of gut bacteria during medical treatments. [1]
