Better Adherence to the Taiwan Daily Food Guide is Associated with a Reduced Risk of Osteoporosis: A Population-Based Study in Taiwan

Introduction: We conducted a study to examine whether adherence to the Taiwan Daily Food Guide was associated with bone mineral density (BMD). Methods: A population-based cross-sectional study was conducted utilizing data from the Nutrition and Health Survey in Taiwan (NAHSIT) 2013–2016. A total of seven BMD sites were evaluated, including the head, arms, legs, trunk, ribs, pelvis, and spine BMD. Besides, we further examined the association between the Daily Food Guide adherence score and osteoporosis (T-score of ≤ −2.5 standard deviation (SD) of a measured total BMD). A validated food-frequency questionnaire (FFQ) was used for dietary assessment. Results: We included a total of 555 participants with osteoporosis and 1977 without osteoporosis in the final analysis. We found negative associations between levels of adherence to the Daily Food Guide and the risk of osteoporosis. The odds ratio (OR) for participants in the highest quartile of the adherence level was 0.61 (95% CI = 0.42–0.88), compared with those in the lowest quartile. When participants had total servings of six food groups higher than the recommendation, the protective effect still existed (OR = 0.59, 95% CI = 0.42–0.84). Conclusion: Better adherence to the Taiwan Daily Food Guide is associated with a lower risk of osteoporosis.
