CMU Researchers Find Gut Bacteria Signal When to Absorb Nutrients
A study led by Zheng Kuang, Eberly Family Associate Professor in the Department of Biological Sciences, showed that gut bacteria can detect when people eat and send signals that help intestinal cells absorb nutrients at the right time of day. The findings reveal a previously unknown link between the microbiome, circadian rhythms and metabolism. New research from Carnegie Mellon University has found that gut bacteria can detect when people eat and send signals that help intestinal cells absorb nutrients at the right time of day. The study, led by Zheng Kuang, Eberly Family Associate Professor in the Department of Biological Sciences, revealed a previously unknown link between the microbiome, circadian rhythms and metabolism. The bacteria metabolizes phytate, a compound found in foods such as nuts, seeds, and grains, which produces molecules that activate a protein in intestinal cells that activates genes responsible for nutrient absorption. The researchers found that bacteria capable of activating this pathway promoted fat accumulation when animals consumed high-calorie diets. The findings suggest that maintaining consistent eating patterns may support a healthy relationship between the microbiology and the body. Future work will explore whether boosting these bacteria could help populations facing food insecurity gain more nutrition and promote healthy growth.

Biological clocks are often associated with light. Historically, most people start their days when the sun is up, and end their days when the sun sets. But new research from Carnegie Mellon University... [3628 symbols]
