When we hear about human diet, it’s often associated with fiber. This type of carbohydrate takes center stage for its essential role in digestion and overall health. However, recent research sheds light on a concerning trend: Western diets, characterized their lack of fiber, may be altering the intricate balance of gut microbes responsible for digesting tough plant matter.
Unraveling the Fiber Puzzle: New Discoveries in Gut Microbiome

According to new research, people living in the city have poor metabolic health, affecting their ability to digest plants.
A groundbreaking study conducted an international team of scientists has uncovered previously undiscovered microbes residing in the human gut with the remarkable ability to break down cellulose, a resilient material found in plant cell walls.

Closing the Gap: Humans and Farm Animals Share Similar Gut Microbes
Contrary to previous beliefs, which suggested that humans lacked the capability to digest cellulose like ruminant mammals, the study revealed the presence of cellulose-digesting microbes in human fecal samples.
Strikingly, these microbes were abundant in samples from hunter-gatherers, rural populations, and ancient humans but conspicuously rare in modern, industrialized societies.
The Decline of Gut Microbes: Impact on Human Health
The researchers hypothesize that the decline of cellulose-munching microbes in the gut of modern populations could be linked to the diminishing consumption of plant fiber. This decline raises concerns about its potential contribution to metabolic health issues prevalent in urbanized communities.
“These findings collectively imply a decline of these species in the human gut, likely influenced the shift toward westernized lifestyles,” the study researchers write.
The team was led microbiologist Sarah Moraïs from the Ben-Gurion University of the Negev in Israel.
Restoring Gut Health: A Potential Solution
Recognizing the significance of these findings, researchers suggest the possibility of reintroducing or enriching these cellulose-digesting microbes in the human gut through dietary supplements or specialized probiotics. This approach holds promise in addressing the health disparities observed in modern societies.
Exploring the Health Benefits of Fiber Supplementation
Emerging studies indicate that increasing fiber intake, either through dietary changes or supplements, offers a myriad of health benefits. From promoting diverse gut microbiota to modulating immune responses and gene expression, fiber supplementation shows promise in optimizing human health.
While the potential benefits of fiber supplementation are compelling, much of this field remains unexplored, Science Alert reports.
Despite promising associations between fiber intake and health outcomes, the underlying mechanisms require further elucidation through rigorous scientific inquiry.
A Glimpse into Evolutionary Insights
Evolutionary analysis suggests that human-associated strains of cellulose-digesting bacteria may have originated from interactions with ruminant mammals during domestication.
Over millennia, these microbes have adapted to their new environment within the human gut, playing a vital role in our digestive health.
Protecting Our Gut Microbes: A Call to Action
As our diets continue to evolve, preserving the delicate balance of gut microbes becomes increasingly crucial. The decline of cellulose-digesting microbes in modern populations highlights the need for proactive measures to safeguard our gut health and overall well-being.
Complexities of Gut Microbiome
The discovery of cellulose-digesting microbes in the human gut unveils a new frontier in understanding the intricate relationship between diet, gut health, and human evolution.
By unraveling the mysteries of fiber digestion, we pave the way for innovative interventions to promote optimal health and vitality in modern societies.
