Garambullo: The Cactus Fruit Showing Promise in Colon Cancer Prevention
Researchers at the Advanced Biomedical Research Center (CIBA) of the Autonomous University of Querétaro (UAQ) in Mexico have uncovered compelling evidence suggesting that consuming garambullo, a cactus fruit native to the Bajío region, may offer preventative and delaying effects against colon cancer. The findings, published in February 2026, represent a significant step forward in understanding the potential of traditional foods in combating chronic diseases.
How Garambullo Impacts Gut Health and Cancer Cells
The research, led by Dr. Aide Vergara Castañeda and doctoral student Edelmira Sánchez Recillas, focused on evaluating the effects of garambullo consumption on an early-stage cancer model in animals. Sánchez Recillas explained that the fruit demonstrably kills cancer cells and delays the progression of primary lesions. Crucially, garambullo as well promotes the growth of beneficial gut bacteria, acting as a “protector for intestinal health.”
This impact on the gut microbiome is a key element of the discovery. “We all have an intestinal microbiota that helps us digest fiber,” Sánchez Recillas noted. “Depending on our diet, we can have good bacteria that provide health benefits and pathogens that can cause inflammation and damage.” The study marks the first time changes in the intestinal microbiota have been directly linked to garambullo consumption.
Rich in Antioxidants and Bioactive Compounds
Garambullo is particularly rich in fiber and antioxidants, even surpassing levels found in blueberries and strawberries. These bioactive compounds, including betalains responsible for the fruit’s vibrant purple color, play a crucial role in reducing chronic inflammation – a key factor in the early stages of colon cancer development.
The research suggests that a diet low in fiber and high in red meat or fats increases the risk of colon cancer. Incorporating foods like garambullo could contribute to prevention by modifying dietary habits and bolstering gut health.
Traditional Use and Future Research
Garambullo has long been utilized by rural communities in Guanajuato and Querétaro, particularly by women who use it to create candies, dried fruits, popsicles, and snow cones. The research team hopes to build on this traditional knowledge by adding scientific validation and promoting the fruit’s consumption.
While the current research has been conducted on animal models, the CIBA team is actively working towards transitioning to human studies. “Ideally, we would like to evaluate whether people who consume it more regularly show some changes compared to the rest of the population,” Sánchez Recillas stated.
Protecting Garambullo’s Future
The increasing industrial development in Querétaro poses a threat to garambullo populations, as land acquisition for construction often leads to the removal of this endemic plant without relocation efforts. Researchers are advocating for the protection of this valuable resource, highlighting its health benefits and cultural significance.
Even in processed forms like snow cones or flavored water, garambullo appears to retain its beneficial fiber and antioxidant content. The fruit’s versatility and accessibility make it a promising addition to preventative dietary strategies.
