Complementary and Alternative Medicine: Consumers' Experience With Food Therapy in Traditional Chinese Medicine in Hong Kong.

Context: The trend of people using complementary and alternative medicine (CAM) has been increasing globally. To enact policies and regulations that promote the safe use of CAM, a detailed investigation is needed into people's knowledge, practices, and beliefs related to CAM. Food therapy has long been regarded as an important part of traditional Chinese medicine (TCM), a type of CAM. Objective: This study intended to empirically examine the public's knowledge about TCM food therapy, including the sources of that knowledge, actual practices, and the public's beliefs about the therapy. Design: The research team designed a questionnaire to test the public's understanding of food properties as designated in TCM food therapy and to identify the public's sources of knowledge and experience in using food therapy. Setting: The study took place at the College of Professional and Continuing Education, the Hong Kong Polytechnic University, and the University of Hong Kong in Hong Kong, China. Participants: Participants were 447 Chinese students participating in postsecondary or tertiary education at the two higher education institutions mentioned above. Outcome Measures: The survey's quantitative questions examined respondents' prior TCM knowledge, sources of knowledge, and food therapy experience compared to their ability to correctly categorize 24 foods. The survey's qualitative questions examined the general practice of food therapy and the cultural beliefs underlying the food therapy strategies that participants used. Results: The study showed that: (1) having prior and partial knowledge of food properties (P = .000); (2) seeking information from the internet (P = .000), television (P = .0473) and friends (P = .0181); and (3) having used food therapy for chronic conditions (P = .0034) significantly improved participants ability to correctly categorize foods as to their food therapy characteristics. Conclusions: Participants relied less on traditional medical sources such as parents and health professionals but more on the internet, which may have empowered them through wider access to information. The study has further contributed to the study of Complementary and Alternative Medicine (CAM) by highlighting the role of cultural practices and beliefs in TCM food therapy.

Chinese adults' nutrition label literacy in Hong Kong: Implications for nurses.

The study aimed to investigate Chinese adults' nutrition label literacy in Hong Kong. It employed a web-based survey with structured questions. A total of 368 Chinese adults aged 18-59 participated in the survey and their nutrition label literacy was measured by the Newest Vital Sign (NVS). About two-thirds (68%) of the participants had limited nutrition literacy skills. Although they were able to identify correctly the calorie and sugar content of food products, 44% and 48% of them had difficulty in determining the consumption of calories and serving food sizes respectively. Another finding from the survey was that those with lower education level and of older age had significantly lower mean nutrition label literacy scores, which indicated that they were at higher risk for food insecurity. The findings showed that the nutrition label literacy level of Hong Kong's general public is quite low. This study can provide insights for nurses and healthcare professionals on how to educate people with lower education level and/or of advanced age to use nutrition labels more effectively and to further nutrition label literacy study and research, particularly in Hong Kong.
