Core Tip

Core tip: Unregulated “unhealthy” body constitution (BC) with an imbalanced Yin and Yang can induce chronic diseases. Past research findings support that food has natures that can regulate the “unhealthy” BC by balancing Yin and Yang. Yin-, Yang- and Yin-Yang-deficiency are the common “unhealthy” BC types in diabetes mellitus (DM). In order to identify the “unhealthy” BC presentations, it was necessary for dieticians to develop the Yin-Yang Assessment Questionnaire for DM. It has passed the initial validation and will be tested further for construct validity, convergent and discriminant validities, responsiveness and predictive validity; scoring system validity, comprehensibility, test-retest and internal consistency reliabilities.
