Antibiotics for cesarean section births are just as effective when they’re given after the umbilical cord is clamped as before clamping – the current practice – and could benefit newborns’ developing microbiomes, according to Rutgers co-authored research. The study, by far the largest of its kind and published in the journal Antimicrobial Resistance & Infection Control, challenges current recommendations for antibiotic use. Administering antibiotics after clamping does not increase the risk of infection at the site of C-section incisions, the study concludes.

Scientists have discovered that one of the good bacteria found in the human gut has a benefit that has remained unrecognized until now: the potential to reduce the risk for heart disease.
After one consumes food or a beverage containing fructose, the gut helps to shield the liver from damage by breaking down the sugar. However, the consumption of too much fructose can overwhelm the gut, causing fructose to “spill over” into the liver, where it wreaks havoc and causes fatty liver, researchers discovered.
