INTRODUCTION Because foods fortified with calcium are increasingly available, the calcium content of calcium-fortified foods may not be adequately captured in traditional assessments of dietary intake, such as dietary records analyzed with commercially available software. The primary objective of our study was to design and test a calcium-focused food(More)
An 8-week, bone-health community program addressed risks/lifestyle changes within the Health Belief Model and Theory of Reasoned Action frameworks in a randomized format (treatment group n = 35; control group n = 34). Median week 1 values for calcium (control, 963 mg; treatment, 1023 mg) and vitamin D (81 IU both groups) were below recommendations,(More)
To determine clinically useful predictors of calcium retention during postpubertal growth, calcium balance, bio-chemical markers of bone turnover, and anthropometric variables were determined in 14 girls aged 11-14 y and in 11 young women aged 19-30 y. Subjects participated in a 3-wk calcium-balance study with a calcium intake of 1332 mg/d. Biochemical(More)
A 3-wk metabolic study measured calcium balance in 14 white adolescent girls and 11 young adult women. Subjects were housed in a sorority to simulate a free-living environment. A 6-d menu cycle consisted of foods typically eaten by teenagers and averaged 1332 mg Ca/d. Adolescents had a significantly higher calcium balance of 326 +/- 107 mg/d (mean +/- SD)(More)
Obtaining sufficient amounts of absorbable dietary calcium to optimize bone density and to protect against bone resorption is a protective measure to lower the risk of osteoporosis. This goal is difficult in Western-style diets without the inclusion of dairy foods, fortified foods, or supplements. Lactovegetarians are able to meet recommended calcium(More)
Bone health is an important issue in aging. Calcium and vitamin D currently have the most focus in published research on nutrition and bone health in aging, although evidence from published research is not conclusive. A systematic review was conducted to determine the impact of dietary and supplemental interventions focused on calcium and vitamin D over the(More)
Racial disparity in osteoporosis between older black and white women is well established; however, less is known regarding daily dietary and supplemental calcium intake in these populations. Moreover, racial differences in calcium intake are confounded by differences in socioeconomic status (SES). The objective of this study was to assess calcium intake and(More)
