Beetroot Test: A Simple Way to Observe Digestive Transit Time

Have you ever wondered how long it takes for food to travel through your digestive system?

Our digestive system works tirelessly, but how do we know if it’s running efficiently? One of the most straightforward ways to assess gut health is by measuring transit time — the duration it takes for food to travel through our digestive tract and exit as stool.

The beetroot test offers a free, non-invasive method to check this from the comfort of our home. 

What Is Digestive Transit Time?

Digestive transit time refers to how long material takes to move through our gastrointestinal (GI) tract. It’s one way (not a medical test) to monitor how quickly our gut is moving. This beetroot-based method is simple, but keep in mind:

• It’s not a diagnosis
• Many factors affect results (diet, hydration, gut bacteria, medications, sleep, stress)

When we eat, food travels through several stages: Mouth → Esophagus → Stomach → Small Intestine → Large Intestine → Rectum.

Our digestive system breaks food down, absorbs nutrients and water, and eventually eliminates the remaining waste as stool. Movement through the digestive tract is controlled partly by muscular contractions. The small intestine is especially important because it absorbs most of the nutrients from the food we eat.

 Why beetroot?

Beetroot contains natural pigments called betalains. These pigments can colour our poop when they pass through our digestive system. The idea is:

• Eat beets
• Observe when the red/pink colour appears
• Use the time difference as a rough estimate of transit time

How to Perform the Test

Step 1: Choose Beets 

For the most accurate results, eat whole beets. We can have beetroot:

• Cooked
• Roasted
• Steamed
• Raw, if tolerated
• Added to a meal or salad. A moderate serving of ½ to 1 cup of beets is sufficient.

Important: Avoid beet juice for this test. As one source notes, juice “moves through our system faster than whole foods,” which can skew our results and give us an inaccurate reading of our actual transit time.

Step 2: Document the Details

Before eating, record the exact date and time of beet consumption. This time is our starting point.

Step 3: Monitor The Stool

Check the bowel movements over the following days. We’re looking for the red or purplish discoloration that signals the beet pigment has made its way through the system.

Step 4: Calculate The Transit Time

When you first notice the colored stool, note the time. The difference between consumption time and the appearance time is the transit time. 

We can repeat the observation for three consecutive days if we want to see whether the result is reasonably consistent.

Understanding The Results

The ideal transit time typically falls between 12 and 24 hours, with some experts extending the normal range to 48–72 hours at the upper limit. Here’s what different timeframes suggest:

Fast Transit (Less Than 12 Hours): If the pigment appears in the stool in under 12 hours, food is moving through the system too quickly. It sounds problematic — the body doesn’t have adequate time to break down food and absorb essential nutrients. Fast transit time can lead to malnutrition and nutrient deficiencies over time. It may also indicate health conditions such as Celiac disease, inflammatory bowel disease (IBD), or gut imbalances.

Normal Transit (12–24 Hours): A result in this range suggests the digestive system is functioning well, properly absorbing nutrients while efficiently eliminating waste.

Slow Transit (More Than 24 Hours): If it takes longer than 24 hours for the pigment to appear, food is lingering in the digestive tract. This is often a sign of constipation or sluggish bowel function. A delayed transit time may also indicate insufficient dietary fibre, dehydration, or ailments like irritable bowel syndrome (IBS). 

The beetroot observation cannot tell us exactly how long food took to travel through every part of your GI tract.

Transit can be influenced by many things, including:

• Fibre intake
• Fluid intake
• Physical activity
• Meal size
• Overall diet
• Individual digestive patterns
• Medications
• Stress and other factors

A beetroot observation should not be used to diagnose constipation or another digestive condition. The beetroot test can help us become more aware of the digestive system. This test only gives a rough estimate of transit time. What matters is:

• consistency of our own pattern
• how we feel overall (energy, stool consistency, discomfort)

Do not do this test if someone is pregnant, has known GI bleeding, severe diarrhea, or active digestive symptoms — check with a physician instead.

If the transit time is too fast, focus on foods that are easy to digest and consider incorporating probiotics to support gut health. If it’s too slow, increasing dietary fibre, staying hydrated, and staying physically active can help promote healthy bowel function.

The beetroot test is a simple, cost-effective way to start understanding our digestive health. By paying attention to how our body processes this vegetable, we gain valuable insight into how efficiently our gut is doing its job.

Our digestive system is much more complex than a single number of hours. Healthy digestion involves proper movement, digestion, nutrient absorption, water balance and elimination.

If an individual has persistent diarrhea, unexplained weight loss, ongoing abdominal pain, blood in their stool, or significant changes in their bowel habits, speak with a qualified healthcare professional rather than relying on a home transit-time observation.
