A study known as the 'Blue Poop Challenge' revealed that the median time for food dyed with blue coloring to pass through the system is 28.7 hours. This shows that blue food dye can stay in your system for approximately one to two days for most healthy individuals, but the rate of excretion is highly variable and depends on a number of personal and dietary factors.

While digestion rates vary widely from person to person, fats and proteins generally take longer to break down than carbohydrates. A fatty meal can take significantly more time to process than a light meal, influencing everything from stomach emptying to overall gut transit time.

The vibrant red pigment in beets, known as betalain, is responsible for the harmless but startling discoloration of urine and stool, a phenomenon experienced by up to 14% of the population. Understanding how long beets take to pass through your system offers a simple, at-home indicator of your overall digestive transit time.
