                                In a study involving over 800 participants, the ZOE blue muffin test revealed that a person’s gut transit time, or the speed of digestion, is a key indicator of overall gut health. This simple test, part of a larger nutrition study, found a strong correlation between faster transit times and better health outcomes.
