The relationship between diet and serum iron, copper, and selenium levels and mood levels in young adults

Nutritional habits and serum iron, selenium, and copper levels have significant effects on mood in young adults. Nutrition is a determining factor not only in meeting an individual's physiological needs but also in maintaining mental health. Trace elements such as iron, selenium, and copper play critical roles in neurotransmitter synthesis, oxidative stress regulation, and central nervous system function. Literature has shown that deficiencies in these elements may be associated with depression, anxiety, and mood disorders. In this context, ensuring a balanced diet and adequate micronutrient intake are crucial for maintaining mental health. This review emphasizes the multidimensional nature of the relationship between nutrition and mood in young adults, and that regular monitoring of micronutrient levels and encouraging healthy eating habits can be a preventative approach.
