A recent study by the University of Minnesota, supported by numerous institutions such as the Great Ape Heart Project and the Detroit Zoological Society, has uncovered notable differences in the gut microbiomes of gorillas depending on their heart health and living conditions. Published in Nature Biofilms and Microbiomes, the research indicates that gorillas with heart disease harbor a less diverse range of gut bacteria compared to their healthy counterparts, and they seem to lack the capacity to produce beneficial compounds, as reported by the University of Minnesota.
These findings stem from an extensive survey of gut microbe composition in both zoo-housed and wild gorillas. Associating with various zoos across the U.S. and Europe, and exploring populations in the Central African Republic, the scientists highlighted a disparity between the microbiomes of gorillas in captivity and those in the wild. Captive gorillas, despite being subjected to more varied diets which likely increase microbiome diversity, still manage to possess a microbiome that seems to struggle when it comes to heart disease. According to Andres Gomez, an associate professor in the Department of Animal Science, "the findings show that lifestyle and diet have been major drivers of the gut microbiome along human evolution, potentially influencing modern diseases, such as heart disease and others of the so-called diseases of civilization," as stated by the University of Minnesota.
The study is pioneering in its approach to link cardiovascular issues with alterations in the gut microbiome, an area that is critical not only to digestive health but also to metabolic and neurological well-being. While the research is primarily focused on gorillas, the implications extend to human health, thinking heavily on how lifestyle factors play a critical role in shaping our microbiome and overall health.
With an eye on the future, the researchers plan to broadly expand their study to include other locations and to pinpoint specific markers of poor intestinal health, in hopes to understand better how diet, environment, and individual factors dictate the microbiome of these zoo gorillas. "The finding that gut microbiome alterations can occur in diseases beyond the gut, such as cardiovascular disease, reinforces the idea that maintaining intestinal health is critical to maintaining our overall health," Gomez shared in a statement made by the University of Minnesota news page.
