Researchers found that eating sugar while taking antibiotics harms beneficial gut bacteria. A study of over 9,000 meals showed that sugary diets combined with antibiotic treatment led to a decline in beneficial bacterial species and an increase in potentially harmful ones.
Eating more sugar while taking antibiotics may make the damage worse. This is according to new research on the intestinal microbiome, which is the community of bacteria living in our gut. These bacteria help us digest food, fight off infections, and even produce some vitamins.
Antibiotics are commonly prescribed medicines that can kill both good and bad bacteria. However, this disruption can allow potentially dangerous species to gain an advantage. A diverse microbiome is generally better able to resist the expansion of harmful pathogens. But antibiotic treatment can reduce that diversity, leaving our gut ecosystem more vulnerable to disease.
Researchers from NYU Langone Health, City of Hope, and Memorial Sloan Kettering closely monitored 9,419 meals consumed by 173 hospitalized cancer patients. They tracked changes in their gut microbiomes and found that for every additional 100 grams of sugar eaten during the 48 hours before treatment, there was an additional 21% decline in alpha diversity. This is a measure of the variety of beneficial bacterial species found in the gut.
The findings also showed that sugary diets combined with antibiotic treatment were associated with increases in Enterococcus faecium among patients. This bacterial species has been linked to infections that can be difficult to treat. Mouse experiments produced similar results, with animals exposed to the antibiotic biapenem while consuming dietary sucrose experiencing a 16.3-fold increase in the gut Enterococcus population by day 3 of the study.
The researchers suggest that modifying diet during and after antibiotics, specifically by reducing sweets intake, could help limit unintended health risks.
Why It Matters
This research is important for Indian students because it highlights the importance of a healthy diet in maintaining a balanced gut microbiome. A well-balanced diet can help prevent infections and promote overall health, which is crucial for students who may be taking antibiotics or facing other health challenges.
