In the 8-week intervention using the 'Shadow Queen' cultivar, what subjective mental health measures showed significant improvement compared to placebo?
Psychological stress response, irritability, and depression assessed by BJSQ.
Recent trials involving anthocyanin-rich purple potatoes, specifically using the relative cultivar 'Shadow Queen,' provided evidence for benefits extending beyond physical health into mental well-being. Over an eight-week study period, subjects consuming the anthocyanin-rich potato daily reported substantially lower scores on measures related to psychological stress response, irritability, and symptoms of depression, as formally assessed using the Brief Job-Stress Questionnaire (BJSQ). While the study did not find a significant impact on the predetermined primary outcome regarding mesenchymal stem cell counts, the observed reduction in these subjective complaints suggests a tangible positive modulation of mood and stress levels resulting from the daily food-based intake of these beneficial compounds.
