There's a lot of myths and misconceptions about what drinks make you poop, but based on scientific research and what we know about the human body, there are three beverages that definitely will relief those bowels from being backed up.
1) High-Fiber Foods -- While not technically a drink, high fiber food is one way to move things along quickly. In addition to fruits and vegetables, be sure to eat as much as possible whole grains as well as insoluble fibers such as oats or collagen protein powder.
2) Tea -- Tea helps digest our food by stimulating bowel movements through natural reactions with stomach acid in your system. This fluid can't clear away any acids so increase the amount of fluids consumed when consuming tea!
