What the research shows
In an animal study, fecal transplants from 34 depressed patients were given to rats. According to the report, the rodents showed reduced sucrose preference, anxiety-like behaviors and altered tryptophan metabolism, an amino acid linked to the production of brain chemicals. The source presents the finding as a suggestion, not as proof.
The gut hosts microorganisms that interact with the nervous system, and recent research is exploring whether they play a part in mood changes. Even so, experiments in rats do not show that the same effect occurs in people. Differences between species and the limits of animal models restrict how far these conclusions can be taken.
What it means
The finding suggests that gut microorganisms may contribute to mood changes in animal models. It is not yet known whether the same happens in people, which microorganisms might be involved, or how this would work.
How to read it with care
Read this result with care, because an animal study does not replace a consultation. Anyone considering a change in diet, supplements or treatment should talk to a doctor or another qualified health professional.
