Summary

This study looks at whether eating nuts can help reduce symptoms of depression, anxiety, and stress, and improve memory and thinking skills in young adults. Researchers will enroll 135 university students aged 18 to 25 and measure changes in mood, cognitive function, and a brain-related protein called BDNF. The goal is to see if a simple dietary change can support mental well-being.
