Summary

Story summary

A study from Arizona State University finds that methane-producing gut microbes extract more energy from high-fiber foods.
The study analyzed 17 participants on low- and high-fiber diets and found higher methane production linked to more calories absorbed.
The results suggest gut microbiome composition can affect energy extraction, informing dietary interventions.
High-fiber diets have health benefits, but the impact of methane-producing microbes in modern, low-fiber diets warrants further study.
