Staring down in the toilet bowl, Tim Spector had momentarily forgotten he’d eaten a muffin filled with food coloring. Poking from the well of water was the contents of his bowel, in a shocking shade of electric blue.
Spector, a professor of genetic epidemiology at King’s College London and author of “The Diet Myth,” is calling for members of the public to follow suit and eat blue-colored muffins to monitor their gut transit times. This is the time it takes for food to travel from your mouth to the other end.
