Methods and apparatuses for characterizing life quality of a living entity via hyper-spectral imaging and analysis, and applications thereof, such as managing life quality of a living entity. Includes acquiring hyper-spectral imaging data and information of: anatomical features of the living entity, and substances consumable by the living entity； generating and maintaining a living entity-specific database containing data and information about the living entity； processing acquired living entity anatomical feature and consumable substance hyper-spectral imaging data and information, and living entity data and information； using processed data and information to generate living entity life quality data and information characteristic of life quality of the living entity. Applicable to any living entity (human, animal, plant). Applicable to integrated microelectromechanical (MEM) [chip level] components in desk top devices or miniature smart/intelligent devices. Applicable to generating, processing, or/and utilizing demographic data and information about living entities and consumable substances.
