Healthy Eating May Support Teen Mental Health, Study Suggests

A new study led by researchers at Swansea University indicates that dietary habits may play an important role in shaping adolescent mental health, though scientists say the connection is still being explored.

Published in the journal Nutrients, the review analysed 19 studies examining links between diet and mental well-being in teenagers. The findings suggest that healthier eating patterns are generally associated with lower levels of depression, while poorer diets tend to correlate with increased psychological distress.

The researchers reviewed both randomized trials and long-term observational studies. Evidence around individual nutrients, such as vitamin D, was inconsistent. In contrast, overall dietary quality showed a more reliable association with improved mental health outcomes.

Adolescence is highlighted as a critical period for brain development, making it a key opportunity for early intervention. However, factors like socioeconomic background and gender may influence these outcomes.

The study also identified gaps in research, particularly around mental health areas beyond depression, and called for more comprehensive future investigations.
