Bile irritates the gut wall, as does alcohol, so it sure could cause your chronic diarrhea. Coconut oil doesn't require bile to be processed by your body. Are you using refined or extra virgin coconut oil? If you're using extra virgin, you could be reacting to fungal contamination. Raw vegetables are tough on your gut. Maybe you could replace the daily carrot with cooked bamboo shoots? And if you eat fruit, it's best to cook it too. Instead of drinking Red-Bull, why don't just drink some good ol' plain coffee with lots of sugar and milk? Oh, and bitter foods also increase bile output, so be careful with that!
