Recent research reveals that the bacteria that help us digest food also influence what’s on our minds. The discovery that these microbial partners are our collaborators in cogitation as well as digestion unfortunately coincides with a separate study suggesting antibiotics can kill off gut bacteria permanently.

The good news:

“Hundreds of species of bacteria call the human gut their home. This gut ‘microbiome’ influences our physiology and health in ways that scientists are only beginning to understand. Now, a new study suggests that gut bacteria can even mess with the mind, altering brain chemistry and changing mood and behavior (abstract).”

The bad news:

Helpful bacteria in our intestines take a pounding during an antibiotics treatment, but normally recover. Or so we thought. A new study suggests the drugs may permanently alter collections of healthy microbes in pregnant women and young children — for worse.
