Popis: Dietary boron (B) intakes were estimated from six countries selected because of the availability of adequate food consumption survey data and nutrient databases (with the exception of boron), and a wide variety of dietary patterns were represented. Large-scale nationwide survey data were provided by the United States (1989–91), Germany (1985–89) and Great Britain (1986–87). Survey data from rural agricultural communities of Mexico, Kenya, and Egypt were provided by the Human Nutrition Collaborative Research Support Program (1983–86). A boron nutrient database was created to include boron concentrations for the foods consumed in each country. This database incorporated boron analytical data from various sources in the United States, Finland, United Kingdom, Italy, Japan, and China. Each person's average daily boron intake was estimated by linking the boron database with the survey food records. Mean dietary intake estimates for adults in the United States, Germany, Great Britain, Mexico, Kenya, and Egypt, respectively, were 1.11 ± 0.69, 1.72 ± 0.47, 1.30 ± 0.63, 2.12 ± 0.69, 1.95 ± 0.57 and 1.31 ± 0.50 mg B/d for males and 0.89 ± 0.57, 1.62 ± 0.76, 1.14 ± 0.55, 1.75 ± 0.48, 1.80 ± 0.49 and 1.24 ± 0.40 mg B/d for females. The major contributors to dietary boron intake were identified in each country. The top contributors in the United States, Great Britain, Germany, Mexico, Kenya, and Egypt, respectively, are coffee (6.5%), wine (14%), wine (15.4%), tortillas (56.1%), maize (35.3%), and rural breads (27.4%). These dietary boron intake estimates provide data that will be useful for setting recommended daily intake levels when boron is confirmed to be essential in humans. J. Trace Elem. Exp.
