This simple at-home test can reveal how fast your digestive system works

When it comes to gut health, one of the most important, and also overlooked, is gut transit time. This factor determines how long food takes to travel through the digestive tract. Although there are clinical methods to measure transit time, there’s an intriguing and surprisingly simple home method that can work like a speedometer for the gut. The simple method is called the Sweetcorn test.

Note: This is a rough, qualitative test, and not as precise as clinical transit studies.
