In this episode of Zoe Science & Nutrition, Dr. Tricia Pasricha, a Harvard Medical School gastroenterologist and author of 'You've Been Pooping All Wrong,' dives deep into the often-overlooked world of bowel health and its profound connection to brain function. She debunks the myth that pooping once a day is the gold standard, emphasizing that comfort, ease, and individual patterns matter more than frequency. Dr. Pasricha explains how stool color and consistency—using the Bristol Stool Scale as a guide—can reveal critical health insights, with red or black stool signaling potential serious issues like colorectal cancer, especially concerning given rising rates in younger populations. The episode highlights the gut-brain axis, revealing that the gut has its own nervous system (the enteric nervous system) and can actually initiate conditions like Parkinson’s disease decades before brain symptoms appear, with misfolded proteins traveling from the gut to the brain via the vagus nerve. She also discusses how modern habits—like smartphone use in the bathroom, poor posture, and ultra-processed diets—contribute to constipation, hemorrhoids, and long-term health risks. Practical advice includes increasing fiber intake (30+ grams daily), eating diverse plants and fermented foods, improving posture with a footstool, reducing screen time in the bathroom, and prioritizing sleep and exercise for gut motility. The episode concludes with a strong call to pay attention to your body’s signals and embrace the gut as a vital organ in overall health and mental well-being.
Pooping once a day is not a requirement—comfort, ease, and consistency matter more than frequency.
Stool color changes (especially red, black, or clay-colored) can be early warning signs of serious conditions like colorectal cancer or bile duct blockages.
The gut has its own 'brain' (enteric nervous system), and diseases like Parkinson’s may start in the gut decades before brain symptoms appear.
Using your smartphone in the bathroom increases hemorrhoid risk by 46% and can lead to prolonged sitting and constipation.
Aim for 30+ grams of fiber daily from diverse plants, including kiwis and prunes, to support healthy bowel movements.

The Gut's Secret Language: What Your Poop Is Trying to Tell You
“What many of us don't realize is that our stool holds clues to a surprising number of our body's secrets. It can help identify life-threatening diseases, reveal the state of our microbiome and even offer insights into our brain health.”
Debunking the 'Once a Day' Myth and Understanding Healthy Bowel Movements
“Normal and healthy is what is comfortable for you. So it should really do two things. One, it should be comfortable, meaning you shouldn't be straining. You shouldn't be spending 20, 30 minutes in the bathroom at a time.”
The Red Flags: When Color and Consistency Signal Serious Health Issues
“Shiny black, tarry kind of sticky black. That's abnormal. I want you to run that by your doctor. Even if the most common answer and most common reason... it's probably hemorrhoids. We see this all the time and then we could miss something more important.”
The Gut-Brain Axis: How Your Stomach Influences Your Mind
“For a subset of patients... the misfolded protein called alpha-synuclein... we think it starts to misfold first in the gut decades before it reaches the brain. And that's sort of the long-term goal of all of our research programs: to identify and stop it before we get there.”
Modern Lifestyle Traps: Phones, Posture, and Processed Foods
“Just bringing your smartphone into the bathroom was associated with a 46% increased risk of having hemorrhoids. That's not a joke. That's a big number right there.”
