Original title: Low-fiber diet hinders the recovery of gut microorganisms
Experiments in mice have shown that low-fiber food health can hinder the recovery of a healthy gut microbiome after antibiotic therapy.
Kerwyn Casey Huang of Stanford University in California and colleagues studied the gut bacteria of mice implanted with human gut microbes. For five days, the team treated mice with common antibiotics, such as streptomycin and cyclopropylsacin. The results were published recently in Cells - Hosts and Microbes.
found that within half a day of rodents starting using antibiotics, the density of gut microbes dropped 100,000 times. Some microbial species began to recover on the third day of antibiotics, but mice fed foods with lower fiber levels had a delayed recovery time.
also injected mice with streptomycin and found that mice raised alone recovered more slowly than among the group. Streptomycin destroys different strains in different animals, and mice living in groups may rebuild the gut microbiome more quickly by absorbing microbes from their "roommates".
authors argue that a fiber-free diet and a highly clean environment prevalent in Western societies may hinder the recovery of the microbiome in people taking antibiotics.
