Here’s What Soda Does to Young Rats’ Brains

Soda is on the mind. A new small study in rats found that drinking sugary beverages may result in memory issues down the line.

University of Southern California researchers looked at adult and adolescent rats, and feed them sugary beverages (meant to mimic soda) for a month. After a month, the rats completed tasks that assessed their cognitive function and memory. The adult rats had no problems, but the adolescent rats who had been drinking sugary beverages had impaired memory and trouble learning.

The findings are being presented at the Annual Meeting of the Society for the Study of Ingestive Behavior (SSIB), and are preliminary. The researchers plan to explore whether the soda is causing inflammation in the brain’s hippocampus, which is the region of the brain involved in memory and learning.

Though the research has not been done in humans, it’s part of a growing body of work looking at the risks of soda.
