How Gut Bacteria Tell Their Hosts What to Eat according to : Scientific American

"One of the big evolutionary mysteries is why we lost the ability to produce essential amino acids," he says. Another group got a mix that had some of the amino acids needed to make protein but lacked essential amino acids that the host cannot synthesize by itself. "This shows that the gut microbiome has evolved to titrate only the normal essential amino acid intake," Ribeiro explains. First, they fed one group of flies a sucrose solution containing all the necessary amino acids. The researchers found the flies' amino acid levels were still low, indicating the bacteria were not simply replacing nutrients missing from the flies' diet by producing the amino acids themselves.




Results showed that patients did indeed have different patterns of gut bacteria disturbances depending on whether they had only chronic fatigue syndrome or both chronic fatigue syndrome and IBS. Previous studies have already found district differences in gut bacteria in chronic fatigue syndrome patients compared to healthy people. The reason for the link between chronic fatigue syndrome and IBS is not clear; chronic fatigue syndrome may predispose patents to developing IBS, or the two conditions might share underlying causes, the researchers said. However, it's also possible that changes in gut bacteria are a consequence of having chronic fatigue syndrome. People with chronic fatigue syndrome may have imbalances in their gut bacteria, a new study suggests.

Are Gut Bacteria Linked to Chronic Fatigue Syndrome?

To explore a potential association between chronic fatigue syndrome and an imbalance in the gut environment, researchers recruited 50 patients with chronic fatigue syndrome and 50 healthy peers from four U.S. cities. What the investigation found is that people with chronic fatigue syndrome "have different bacteria in their intestines than healthier people," Lipkin said. Whether these differences are merely a sign of chronic fatigue syndrome or an underlying cause isn't clear, said study lead author Dr. W. Ian Lipkin. By Alan MozesHealthDay ReporterTHURSDAY, April 27, 2017 (HealthDay News) -- Scientists have found differences in the gut bacteria of people with chronic fatigue syndrome versus their healthy peers. The finding is among the first to link abnormalities in the makeup of gut bacteria -- the "microbiome" -- and chronic fatigue, a mysterious and debilitating malady.
