What this trial studies

This is a randomized controlled trial comparing a six-month mixed-nut dietary intervention to a control group in university students aged 18–25. Participants will be randomized to receive mixed nuts or control and will be followed with measures of mental health symptoms, cognitive functioning, sleep quality, well-being, health-related quality of life, and biochemical markers related to brain function. The trial takes place at the Health and Social Research Center of the University of Castilla‑La Mancha (Cuenca campus). People with known nut allergies or self-reported cardiovascular, metabolic, gastrointestinal, or mental health disorders are excluded.

Who should consider this trial

Good fit: University students aged 18–25 enrolled at the Cuenca campus who do not have a nut allergy and do not report cardiovascular, metabolic, gastrointestinal, or mental health disorders.

Not a fit: People with a known nut allergy, those with existing diagnosed mental health or relevant medical disorders (who are excluded), and individuals outside the 18–25 Cuenca university student population are unlikely to be helped by this study.

Why it matters

Potential benefit: If successful, this simple dietary approach could reduce symptoms of depression and anxiety, improve sleep and cognitive function, and enhance overall well-being in young adults.

How similar studies have performed: Observational studies in adults have linked higher nut intake to better mood and lower depression risk, but randomized experimental evidence in young adults is limited and results have been inconclusive.
