You're sitting there, minding your own business, and then you look down. It’s bright red. Or maybe a deep, alarming magenta. Your heart skips. You start mentally cataloging every meal you’ve had in the last 48 hours, wondering if this is the end. Relax. Honestly, if you had a salad with those earthy, purple-stained slices last night, you’re probably just experiencing a harmless phenomenon called beeturia.
So, can beetroot make faeces red? Yes. Absolutely. It can also turn your urine a shade of pink that looks like it belongs in a watercolor painting.
It’s one of those things that shouldn't be a surprise, yet it catches people off guard every single time. It's actually a bit of a medical classic. Doctors see patients rushing into clinics convinced they have an internal hemorrhage, only to realize they just really enjoyed a roasted beet and goat cheese salad at dinner.
The Science of the "Red Scare"
The culprit is a compound called betanin. This is the pigment that gives beets their aggressive, unmistakable color. Most of the time, your body is pretty good at breaking down these pigments. However, when betanin isn't fully broken down by your stomach acid or processed by your digestive enzymes, it travels through your system mostly intact.
It’s a pigment powerhouse.
It doesn't just sit there; it stains everything it touches. Because your GI tract is essentially a long tube, whatever doesn't get absorbed comes out the other end. When that betanin hits your stool, it creates a visual that looks remarkably like blood. This is why people freak out.
Interestingly, not everyone experiences this. Research suggests that only about 10% to 14% of the population gets "beeturia" (red urine), though the prevalence of red stool from beets is likely much higher depending on how much you actually ate. The acidity of your stomach plays a massive role here. If your stomach acid is a bit low, the pigment survives the journey more easily.
If you're taking antacids or have a condition like atrophic gastritis, you’re way more likely to see a colorful surprise the next morning.

Is it Beets or is it Blood?
Distinguishing between "beet red" and "blood red" is a skill you didn't think you'd need, but here we are. Blood in the stool—medically known as hematochezia if it’s bright red—usually looks different. Blood tends to be "thicker" in appearance or might appear as distinct streaks on the surface of the stool.
Beet-induced redness is usually more homogenous. It looks like the stool has been dyed. Think of it like food coloring in cake batter versus adding chocolate chips.
Another weird nuance? Iron levels. There’s a fascinating link between iron deficiency and beeturia. While the mechanism isn't perfectly understood, people with low iron levels or those who struggle with iron absorption often see much more vibrant red or pink colors after eating beets. If you are seeing red every single time you eat even a small amount of beetroot, it might actually be worth asking your doctor to check your ferritin levels.
Timing is everything
How long ago did you eat? Digestion takes time. If you ate a beet burger three days ago and you're just now seeing red, that might be a bit of a stretch for most people's transit times, though it's not impossible if you have a slow metabolism. Usually, the "red zone" happens between 12 to 48 hours after consumption.
If the redness persists for several days after you’ve stopped eating beets, that's a red flag. Literally.
When you should actually worry
I’m not a doctor, and this article isn't a substitute for a medical exam. While beets are usually the innocent party, you shouldn't ignore certain symptoms just because you had a smoothie yesterday.
If you see red and you're also feeling:

- Dizzy or lightheaded
- Severe abdominal pain that feels like cramping or stabbing
- Persistent diarrhea or a major change in bowel habits
- Extreme fatigue
Then it’s time to call a professional. Blood in the stool can be a sign of anything from hemorrhoids and anal fissures to more serious issues like inflammatory bowel disease (IBD), polyps, or colorectal cancer.
The "Paper Test"
Here is a gross but effective tip: look at the toilet paper. Beet pigment tends to look more like a magenta or fuchsia stain on white paper. Real blood is usually a true, bright "fire engine" red or, if it’s coming from higher up in the digestive tract, it can look dark, tarry, and black (melena). If your stool looks like coffee grounds, stop reading this and go to the ER. That is digested blood and it’s a medical emergency.
Other foods that play tricks on you
Beets aren't the only pranksters in the pantry. If you're wondering can beetroot make faeces red, you should also know about these other culprits:
- Dragon fruit: Specifically the red-fleshed variety. It can turn everything a startling shade of pink.
- Blackberries and Blueberries: These often turn stool a very dark blue, green, or even blackish-purple.
- Red Food Dye: Think Red 40. Huge amounts of red velvet cake, Flaming Hot Cheetos, or red Gatorade can create a very convincing imitation of a medical crisis.
- Rhubarb: Sometimes causes a brownish-red tint.
Actually, the amount of red dye in modern processed snacks is one of the leading causes of "false alarms" in pediatric emergency rooms. Kids eat a whole bag of red corn chips, and parents—rightfully—panic when they see the results.
Why do we even eat these things if they scare us?
Because beets are incredible for you. They are packed with nitrates, which your body converts into nitric oxide. This relaxes your blood vessels and can actually lower your blood pressure. Athletes love beetroot juice because it improves oxygen usage and stamina.
So, don't stop eating them just because of the "theatrical" exit. They are nutrient-dense powerhouses rich in fiber, folate, and manganese.
The fear comes from a lack of "stool literacy." We aren't taught to look, but our waste is a direct report card of our internal health. It’s okay to be startled. It shows you’re paying attention.

Actionable Steps for the Next 24 Hours
If you’ve just noticed red in the bowl and you did eat beets recently, here is what you should do:
1. Track the timeline.
Stop eating beets immediately. Note the time. Most people will clear the pigment within 24 to 48 hours. If you are still seeing red on day four, it wasn't the beets.
2. Check your hydration.
Dehydration can concentrate pigments, making the color look even more intense. Drink plenty of water to help your kidneys and digestive tract flush things through.
3. Assess your iron.
As mentioned, if this happens every single time you eat a tiny bit of beet, consider a routine blood test. It’s a subtle clue your body might be giving you about iron malabsorption.
4. Perform a visual check.
Is the red in the stool or on it? Is there mucus? Is it accompanied by pain? If it's just "dyed" stool and you feel fine, breathe. You're okay.
5. Keep a food diary.
If you have a sensitive gut, keep track of what you eat. It helps rule out food sensitivities versus simple pigment staining.
The bottom line is that while can beetroot make faeces red is a question that leads many to a frantic Google search, the answer is almost always "yes, and it’s fine." It’s just your body's way of showing you exactly what you put into it.
Next time, maybe just stick to the golden beets if you want to save yourself the mini heart attack. They have the same nutrients but none of the "crime scene" visuals.
