Brain – Gut Bacteria: Recent Research

NPR recently had a program where they found the brain MRI’s and gut bacteria were related. The program is here. An example quote:

…they’ve found changes in both brain chemistry and behavior. One experiment involved replacing the gut bacteria of anxious mice with bacteria from fearless mice. “The mice became less anxious, more gregarious,”  It worked the other way around, too — bold mice became timid when they got the microbes of anxious ones. 
 

This suggests that many psychologists and psychiatrists may be replaced by a bottle of ‘designer probiotics‘. One example from the literature referenced as a probiotic containing:

  • Bifidobacterium animalis subsp Lactis,
  • Streptococcus thermophiles,
  • Lactobacillus bulgaricusand
  • Lactococcus lactis subspLactis.

Unfortunately, the brand or source of this fermented milk was not given. I have been unsuccessful locating any commercial offering precisely matching this offering. Some Kefirs come close, Onaka appears to be a closer match, as well as  Danone’s Activia (“Bifidus Regularis”) which has 3 of the 4 species listed (once you wade thru advertising renaming of species).
