ok i was eating beans at work today at around 1 pm and drinking plenty of grapejuice around 64 ounces and a whole package of beans like 13 servings.
well when i got home at 4 i had to shit and the beans came out and my dump was purple from the grape juice
i was suprised how fast it went through my whole digestive system
i attribute it to the grapejuice, when people start drinking it for the first time in large amounts they get stomach rumbles or feel like there stomach is growling a bit
