Technical Abstract: Boron, in amounts equivalent to those found in diets with plenty of fruits vegetables, and nuts, affecs several aspects of higher animal and human physiology when added to low-boron diets. Knowledge of normal boron intakes are needed to facilitate research regarding the practical nutritional importance of boron and to aid in the establishment of a recommended dietary allowance for humans. Boron concentrations of 234 commonly consumed foods as identified in the FDA Total Diet Study Program (TDS) were determined to estimate boron intakes of various populations. This approach was validated, in part, by applying analyzed boron food values to the 3 one-day diet records of 28 female athletic (1840 kcal/d) or sedentary (1800 kcal/d) college students and comparing that calculated boron intake (1.02 mg/d) to actual boron analysis of individual duplicate plate collections (1.20 mg/d). Application of analytically determined food d boron values to TDS food intake data indicated that the mean daily boron intakes for toddlers is 0.55 mg/d; adolescent (14-16 yrs) males, 0.85; adolescent females, 0.59; mature (60-65 yrs) males, 0.88; mature females, 0.75. The TDS food group that contributed the most to toddlers' daily intake of boron was fruit juices (22%); adolescent males, milk and cheese (19%); adolescent females, milk and cheese (17%); mature males, beverages (26%); mature females, beverages (24%). Mean US dietary boron consumption for mature males as determined by this study is similar to mean consump- tion for all age groups reported earlier in studies that utilized literature-derived analytical values (1.0 mg B/d).
