Abstract: Nutrition education is important for preventing the incidence and/or progression of osteoporosis. This study was designed to comprehensively assess the correlation among levels of knowledge about ‘good-for-bone’ food, dietary intake and Bone Mineral Density (BMD) in an open educational program. The study population included 32 healthy women (Mean age, 54.0±17.4 years), who were divided into 3 groups: ≤39 years (N = 5), 40-59 years (N = 14) and ≥60 years (N = 13). All the participants answered a questionnaire containing questions on what they considered as ‘good-for-bone’ food. In addition, dietary records were analysed and BMD of the calcaneus was measured using ultrasonographic bone densitometry. The results showed that all the age groups before attending the lecture considered milk or dairy products as the most popular good-for-bone food (30/32 participants), followed by fish (24/32). Green vegetables (10/32) and seaweed (8/32) were considered as good-for-bone food only by women above 50 years of age. BMD values showed correlation with the estimated intake of zinc, mushrooms and root crops but not with calcium, vitamin D, or K. Although, most women knew that milk and dairy products protect bones because of their rich calcium content, extensive knowledge regarding the roles of other vitamins and minerals was necessary to prepare and consume balanced diets that are appropriate for lifelong bone health. This study also highlighted the importance of zinc intake in BMD.
