The tool is based on the cMIND diet, a Chinese-adapted version of a known healthy eating pattern that may support memory and thinking skills.\n\nParticipants will use the web app to take photos of their usual meals for at least 10 days over two weeks. The AI will automatically identify ingredients and give a score showing how well the meal follows the cMIND diet. The study will also ask participants to complete a short questionnaire and a brief interview to find out how easy and useful the tool is for older adults.\n\nThe purpose of this small study is to see whether the AI tool is user-friendly and acceptable for older people. Results will help improve the tool for future use to support healthy ageing and brain health.",[46,47,48],"Mild Cognitive Impairment (MCI)","Healthy Aging","Nutrition",[50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69],"cMIND diet","Cantonese Mediterranean diet","AI dietary assessment","web-based AI tool","meal photo analysis","Cantonese mixed dishes","usability testing","older adults","congitive health","mild cognitive impairment","healthy ageing","gerontechnology","nutrition monitoring","dietary adherence","AI food recognition","Cantonese cuisine","brain health diet","feasibility study","acceptability study","Hong Kong older adults","NOT_YET_RECRUITING","2026-07-24",{"date":73,"type":74},"2026-07-29","ACTUAL",{"date":76,"type":42},"2027-09",{"date":78,"type":42},"2028-02",{"name":5,"class":6}]
