Philadelphia, PA, April 27, 2011 Americans may not be getting enough calcium in their diets, according to a new study published in the May 2011 issue of the Journal of the American Dietetic Association. This study is unique among those focusing on calcium intake in the US population because both dietary and supplemental sources were evaluated across adult age groups and compared to accompanying patterns in energy intake.
"Calcium plays a fundamental role in promoting bone health and forestalling osteoporosis. In light of evidence that energy intake declines with aging, calcium dense foods and calcium supplements become vital factors in maintaining adequate calcium intake across the lifespan," commented Jane E. Kerstetter, RD, PhD, Professor, Department of Allied Health Sciences, University of Connecticut. "Encouraging calcium supplementation is an established approach to addressing this issue in the clinical setting one that needs additional emphasis in order to promote more frequent and sufficient supplementation in meeting adequate intake levels. Altering the concentration of calcium in the diet relative to energy by increasing consumption of nutrient dense foods is a new and important concept that also deserves additional consideration as a component of osteoporosis prevention efforts."
Using data collected from 9,475 adults during the National Health and Nutrition Examination Survey (NHANES) of 2003 to 2006, researchers from the University of Connecticut and Yale University found that while self-reported calcium density was highest in older age groups, it was still not sufficient to meet recommended levels. Although reported calcium supplement use increased with age in both men and women, median dietary calcium intake was lower in the 81+ age group by 23% in men and by 14% in 18 women, compared to the median intake reported in the 19-30 year age group. In relating calcium and energy intake, dietary calcium density as well as calci
