Modern Living Is Stripping Our Gut of Healthy Bacteria

Modern Living Is Stripping Our Gut of Healthy Bacteria
Share on FacebookShare on Twitter

Gut Bacteria Microbiome Illustration

Modern diets, especially in industrialized societies, are reducing the presence of beneficial cellulose-degrading bacteria in the human gut microbiome, such as Ruminococcus. Studies indicate these bacteria, essential for a healthy gut due to their ability to break down fiber, have evolutionary ties to domesticated livestock but are now at risk. Reversing this trend and promoting gut health can be as simple as following longstanding dietary advice: eat more fiber.

Fiber is good for us, yet recent research reveals that humans are gradually losing the microorganisms necessary to convert fiber into food for a healthy digestive tract.

Everyone knows that fiber is healthy and an important part of our daily diet. But what is fiber and why is it healthy? Fiber is cellulose, the stringy stuff that plants are made of. Leaves, stems, roots, stalks, and tree-trunks (wood) are made of cellulose. The purest form of cellulose is the long, white fibers of cotton.

Dietary fiber comes from vegetables or whole grain products. Why is fiber healthy? Fiber helps to keep our intestinal flora (scientists call it our gut microbiome) happy and balanced. Fiber serves as the starting point of a natural food chain. It begins with bacteria that can digest cellulose, providing the rest of our microbiome with a balanced diet. But our eating habits in industrialized societies are far removed from those of ancient humans.

This is impacting our intestinal flora, it seems, as newly discovered cellulose-degrading bacteria are being lost from the human gut microbiome, especially in industrial societies, according to a new report in Science. The study comes from the team of Prof. Itzhak Mizrahi at Ben-Gurion University (BGU) of the Negev in Israel, with support from the Weizmann Institute of Science in Rehovot and international collaborators in the US and Europe.

The Role of Cellulose-Degrading Bacteria

“Throughout human evolution, fiber has always been a mainstay of the human diet,” explains lead investigator Sarah Moraïs from BGU, “It is also a main component in the diet of our primate ancestors. Fiber keeps our intestinal flora healthy.” Moraïs and team identified important new members of the human gut microbiome, cellulose-degrading bacteria named Ruminococcus. These bacteria degrade cellulose by producing large and highly specialized extracellular protein complexes called cellulosomes.

“It’s no easy task to degrade cellulose, few bacteria can do it,” explains Ed Bayer, from the Weizmann Institute, a world leader on cellulosomes and coauthor of the study. “Cellulose is difficult to digest because it is insoluble. Fiber in the gut is like a tree-trunk in a swimming pool, it gets wet but it does not dissolve.”

Cellulosomes are engineered by bacteria to attach to cellulose fibers and peel them apart, like the individual threads in a piece of rope. The cellulosomal enzymes then break down the individual threads of fiber into shorter chains, which become soluble. They can be digested, not only by Ruminococcus, but also by many other members of the gut microbiome.

“Bottom line, cellulosomes turn fiber into sugars that feed an entire community, a formidable engineering feat,” says Bayer. The production of cellulosomes puts Ruminococcus at the top of the fiber-degradation cascade that feeds a healthy gut microbiome. But the evolutionary history of Ruminococcus is complicated, and Western culture is taking its toll on our microbiome, as the new study shows.

Evolutionary Insights and Recommendations

“These cellulosome-producing bacteria have been around for a long time, their ancestors are important members of the rumen microbiome in cows and sheep,” explains Prof. Mizrahi from BGU, senior author of the study. The rumen is the special stomach organ of cows, sheep, and deer, where the grass they eat (fiber) is converted into useful food by cellulose-degrading microbes, including Ruminococcus.

“We were surprised to see that the cellulosome-producing bacteria of humans seem to have switched hosts during evolution, because the strains from humans are more closely related to the strains from livestock than to the strains from our own primate ancestors.”

That is, it looks like humans have acquired important components of a healthy gut microbiome from livestock that they domesticated early in human evolution. “It’s a real possibility,” says Mizrahi, an expert on rumen biology.

But the story does not end there. Sampling of human cohorts revealed that Ruminococcus strains are indeed robust components of the human gut microbiome among human hunter-gatherer societies and among rural human societies, but that they are sparse or missing in human samples from industrialized societies.

“Our ancestors in Africa 200,000 years ago did not pick up lunch from a drive-through, or phone in a home-delivery for dinner,” says William Martin at the Heinrich Heine University Düsseldorf in Germany, evolutionary biologist and coauthor of the study.

In Western societies, this does, however, happen on a fairly large scale. Diet is changing in industrialized societies, far removed from the farms where food is produced. This shift away from a fiber-rich diet is a possible explanation for the loss of important cellulose-degrading microbes in our microbiome, the authors conclude.

How can you counteract this evolutionary decline? It might help doing what doctors and dieticians have been saying for decades: Eat more fiber!
