Do vegans poop more?

One common question that often arises when discussing veganism is whether or not vegans poop more frequently than non-vegans. While it may seem like a peculiar topic, it is worth exploring the potential reasons behind this claim. In this article, we will delve into the science behind digestion, the impact of a vegan diet on bowel movements, and whether or not vegans truly do poop more.

The science of digestion

Before we can understand the potential effects of a vegan diet on bowel movements, it is important to have a basic understanding of the science of digestion. The digestive process begins in the mouth, where food is broken down by chewing and mixed with saliva. From there, it travels down the esophagus and into the stomach, where it is further broken down by stomach acid and enzymes.

Next, the partially digested food enters the small intestine, where the majority of nutrient absorption takes place. The small intestine is lined with tiny finger-like projections called villi, which increase the surface area for nutrient absorption. Finally, any undigested food and waste products move into the large intestine, also known as the colon, where water is absorbed and the remaining waste is formed into stool.

The impact of a vegan diet on bowel movements

Now that we have a basic understanding of digestion, let’s explore how a vegan diet may impact bowel movements. A vegan diet is one that excludes all animal products, including meat, dairy, eggs, and honey. Instead, it focuses on plant-based foods such as fruits, vegetables, grains, legumes, nuts, and seeds.

1. Increased fiber intake: One of the main reasons why vegans may experience more frequent bowel movements is due to their higher fiber intake. Plant-based foods are generally rich in fiber, which adds bulk to the stool and promotes regularity. The recommended daily intake of fiber for adults is around 25-30 grams, and a vegan diet can easily provide this amount or even more.

2. Hydration: Another factor that can contribute to increased bowel movements in vegans is their typically higher water intake. Fruits and vegetables, which are staples of a vegan diet, have high water content, aiding in hydration. Proper hydration helps soften the stool and facilitates its passage through the digestive system.

3. Gut microbiome: The gut microbiome, which consists of trillions of bacteria, plays a crucial role in digestion and overall health. Studies have shown that a plant-based diet can positively influence the diversity and composition of the gut microbiome. A healthy gut microbiome is associated with regular bowel movements and improved digestion.

Debunking the myth

While it is true that vegans may experience more frequent bowel movements, it is important to note that this does not necessarily mean they poop more overall. The increased fiber intake and hydration levels in a vegan diet can lead to more regular bowel movements, but the volume of stool may not be significantly different from that of non-vegans.

It is also worth mentioning that individual variations in bowel habits exist regardless of diet. Factors such as genetics, overall health, stress levels, and medication use can all influence bowel movements. Therefore, it is not accurate to make a blanket statement that all vegans poop more than non-vegans.


While the claim that vegans poop more may have some basis in truth, it is important to understand the underlying factors at play. The higher fiber intake, increased hydration, and positive impact on the gut microbiome associated with a vegan diet can contribute to more regular bowel movements. However, individual variations and other lifestyle factors also play a significant role. Ultimately, the frequency and volume of bowel movements can vary greatly among individuals, regardless of their dietary choices.
