Interpretive Summary:

Technical Abstract: Previous findings indicate that dietary boron influences calcium metabolism, findings that may be particularly relevant to females who exhibit osteoporosis in later life. The 234 most commonly consumed American foods, as defined by the FDA Total Diet Study Program, were analyzed for boron content. Additionally, composite diets representative of toddler (TOD; 2 y), adolescent (ADL; 14-16 y), and elderly (ELD; 60-65 y) females were constructed from those foods. All foods were purchased in Grand Forks, ND and prepared for wet weight analysis by inductive-coupled argon plasma spectroscopy. The amount of boron contributed by individual food groups varies widely. For example, the milk products and fruit + fruit juices groups contribute 50 and 234 ug B/d respectively to the diet of ELD females. The concentration of boron in each of the three composite diets was remarkably similar (0.48-0.54 ug B/g). Estimated total boron intakes were 0.87, 0.87, and 1.09 mg/d for TOD, ADL, and ELD females respectively. On the basis of average body weight (BW), TOD consume four times more boron than either ADL or ELD females. The findings indicate that diets modelled on the USDA food pyramid recommendations or the "5-a- Day" Healthy 2000 initiative provide increased amounts of boron.
