A simple trick involving a common food could provide an early warning for several major health conditions. Experts suggest that a quick test using a muffin may help detect risks for diabetes, heart disease, and other health concerns.
Around 5.6 million people in the UK are living with diabetes, and 7.6 million have heart or circulatory diseases. Additionally, 300,000 individuals suffer from inflammatory bowel disease. All of these conditions can potentially be identified early with the help of a specific muffin test involving blue dye.
The Muffin Test: A Simple Indicator of Health Risks
Healthcare professionals have collaborated with research scientists to use a method that involves a muffin made with a strong blue food dye. This technique allows individuals to track the transit time of food through their system, providing valuable insight into the gut’s health and possible indications of underlying health problems.
The key observation lies in the color of the food once digested. If the muffin’s blue dye travels through the digestive system too quickly, it may indicate an issue like inflammatory bowel disease. Conversely, if the process is too slow, it could be an early sign of heart disease. A prolonged transit time of over 60 hours may suggest a risk for type 2 diabetes.
Dr. Sarah Berry, a nutrition scientist from King’s College London, contributed to the study published in the journal Gut, which detailed the muffin challenge. Participants ate muffins dyed with blue food coloring, which turned their stool blue, allowing them to track the digestion process. The goal is to determine how long it takes for the dye to appear in the stool, as this reflects the digestive process.
Understanding the Results: What Transit Times Indicate
According to the study, transit times varied among participants. For some, it took about 24 hours to detect the dye, while others experienced a delay of up to 48 hours. A small group saw the dye appear after 59 hours, which was also considered normal. On average, the blue dye appeared in the stool after 28.7 hours.
A slower transit time, which may indicate more visceral fat—fat wrapped around organs like the liver—could be a risk factor for both type 2 diabetes and heart disease. A quick transit time may suggest a healthy gut microbiome, but too rapid a transit could indicate diarrhea or an imbalance in gut bacteria.
A Simple Test: How to Perform the Muffin Challenge
To try the test yourself, make muffins using a professional-grade blue food dye, as opposed to water-based versions. The researchers suggest using 6g of blue dye for 12 muffins. Eat two muffins for breakfast, then record the time and date. Monitor your stool for a blue or greenish-blue color and note when you see it. The time it takes for the dye to appear will give you your gut transit time.

Improving Gut Health and Reducing Risk
Experts stress the importance of maintaining a balanced gut microbiome for overall health. A gut transit time between 14 and 58 hours is typically considered healthy. Factors such as diet and lifestyle can influence transit time, so individuals are encouraged to understand what is normal for them.
Dietitian Sophie Medlin, who was not involved in the study, noted that faster transit times are usually linked to a healthier gut microbiome, whereas slower transit times can indicate an imbalance. Optimizing gut health through diet and exercise may be key to preventing or managing conditions like heart disease and diabetes.
Ultimately, the muffin test provides a simple, at-home method to monitor potential health risks, offering an early warning sign of issues that could otherwise go undetected.
