Development of gut microbes and gut immunity linked

Studying twins from birth through age 2, scientists at Washington University School of Medicine in St. Louis have shown that the gut’s immune system develops in sync with the gut’s tens of trillions of microbes. The findings have implications for understanding healthy growth and, potentially, the origins of various immune disorders.

Mimicking diet changes of global travel reveals clues to gut health​

With the growing understanding of the importance of gut bacteria in human health, researchers at the School of Medicine studied gut motility, measuring the transit time of food moving through the gastrointestinal tract in mice in a way that mimicked the dietary effects of world travel. The study demonstrates ways to uncover how even a single ingredient, such as turmeric, can affect health through interactions of diet and gut microbes.

A person’s diet, acidity of urine may affect susceptibility to UTIs

The acidity of urine — as well as the presence of small molecules related to diet — may influence how well bacteria can grow in the urinary tract, a new study shows. The research, led by Jeffrey Henderson, MD, PhD, at Washington University School of Medicine in St. Louis, may have implications for treating urinary tract infections, which are among the most common bacterial infections worldwide.
