Decreasing bone density is of concern to women as they age. The purpose of this study was to evaluate the relationship between dietary intake and bone density in adult women. Women (n=33) ages 20-80 yrs, completed two 3-day diet logs, physical activity questionnaire, and bone density scan. Diet logs were evaluated for nutritional profile. Physical activity questionnaire were used to control for the impact physical activity has on bone density. Total body and lumbar spine bone densities were determined using dual-energy X-ray absorptiometry. No correlations to total body bone density were found. Using a stepwise regression, height (cm), alpha-carotene (μg), and alcohol (g) were predictors of total body bone density. With a larger subject number, total fat (r=0.403), molybdenum (r=0.408), isoleucine (r=0.414), cystine (r=0.424), alanine (r=0.418), aspartic acid (r=0.401), and glycine (r=0.427) may become correlated with bone density stronger trends may become evident.
