Summary

Story summary

A study on young female Sprague-Dawley rats investigated high-fructose corn syrup (HFCS) effects on health.
Rats consuming HFCS exhibited increased adrenal gland mass and longer estrous cycles, indicating chronic stress.
Gene expression analysis showed alterations in sleep-wake cycle regulation and the Engrailed-2 gene, associated with autism in humans.
The study involved 28 rats with varying sweetened water solutions.
Findings suggest limiting HFCS may lower neurodevelopmental disorder risks, though results may not directly translate to humans.
