Specific populations of gut bacteria linked to fatty liver

Rather than being controlled itself by diet, gut bacterial composition may control the body's key nutrients. A metagenomic study of gut bacteria during a choline-depletion experiment on patients with fatty liver predicted the nutrient restriction would modify gut microbial ecologies towards uniformity. Instead, results showed each individual's unique microflora bore a strong relationship to fatty liver susceptibility, indicating that two specific groups of bacteria may play significant roles in dietary choline availability.
