Rating (out of 5): 3

Bamboo fiber is increasingly recognized for its role in supporting large intestine (colon) health, primarily due to its high insoluble fiber content. Scientific studies have established that dietary fiber, especially insoluble types, can benefit colon health by increasing stool bulk, promoting regular bowel movements, and reducing the risk of constipation. Insoluble fibers such as those from bamboo are poorly fermented by gut bacteria and therefore help to speed the passage of food and waste through the digestive tract.

Research specifically on bamboo fiber is still emerging, but it is chemically similar to other insoluble fibers like cellulose. Clinical trials and in vitro studies have shown that bamboo fiber supplementation can improve stool form, increase fecal output, and decrease intestinal transit time. These effects are consistent with the well-documented benefits of insoluble dietary fiber for large intestine health.

While there is a lack of large-scale human studies focusing solely on bamboo fiber, its use in food products as a functional fiber is growing, and early evidence supports its inclusion as part of a high-fiber diet for colon support. However, compared to more thoroughly studied fibers (e.g., wheat bran, psyllium), bamboo fiber’s direct effects are less well-documented, hence the moderate evidence rating.
