A recent research by the team of researchers led by Kirsten Tillisch from UCLA found associations between 2 kinds of gut microbiota and how they affect human emotions and feelings.
For their research, the scientists analyzed fecal samples from 40 healthy women aged between 18 and 55. They also scanned the brains of participants. The researchers concluded that women with a greater abundance of Bacteroides in the gut showed the greater thickness of the gray matter in the frontal cortex and insula.
The researchers admit that the sample studied in the research was very small. Nevertheless, it is clearly seen that there’s something going on between our microbiome and the thoughts and feelings we experience.
