Story summary

Rhowena J.B. Matos of the Federal University of Bahia led a rat study.
Pregnant and nursing rats were split into two diet groups: balanced vs. Western diet.
In adulthood, Western diet rats showed higher blood glucose and inflammatory gene expression after brief junk-food re-exposure.
The findings indicate early dietary habits can have lasting impacts on brain health and cognitive function.
Future work will measure protein levels and assess cognitive abilities.
