Background: There has been a rapid increase in the prevalence of psychiatric and psychological disease, and this has attracted interest in identifying modifiable lifestyle factors that may affect an individual’s mood. Diet is one potential lifestyle factor that may affect psychological function. Aim: This study aimed to investigate the relationship between adherence to the health-promoting Nordic diet (ND) with neuropsychological function in young women. Methods: The study comprised 181 female students aged between 18 and 25 years. Psychological function was evaluated using a series of standardized questionnaires, including the Cognitive Ability Questionnaire, Depression Anxiety Stress Scale, Insomnia Severity Index, Epworth Sleep Scale and Quality of Life Questionnaire. A validated food frequency questionnaire, which included 65 types of foods, was used to evaluate the amount of different foods consumed. Results: Evaluation of the dietary composition of the participants showed that the rate of adherence to the ND was positively associated with total energy, carbohydrates, protein, fibre, iron, magnesium, potassium, zinc, folate, phosphorus, vitamin C, thiamine, riboflavin, niacin, vitamins B6 and B12, carotene, whole grain, legumes, cabbage/vegetables, vegetables and fruit (p<0.05). Linear regression showed cabbage/vegetable consumption was inversely related to scores of stress (ß=–0.04; p=0.038) and anxiety (ß=–0.02; p=0.049) and directly associated with the quality-of-life score (0.02; p=0.036). Conclusions: Adherence to a ND with a high intake of cabbage/vegetables was inversely associated with stress and anxiety scores and directly associated with health-related quality of life.
