Nutrient Effects on the Calcium Economy: Emphasizing the Potassium Controversy1,2
|
Abstract
The calcium economy is a dynamic state influenced by fluxes in dietary calcium intake, intestinal calcium absorption, and renal calcium conservation. The relationship of selected bone-related nutrients to these calcium fluxes exhibits both constructive and destructive interactions that affect the overall state of calcium balance. The basis of the calcium requirement and the impact of vitamin D, protein, phosphorus, sodium, and caffeine on the calcium economy are reviewed. Agai...

An Inulin-Type Fructan Enhances Calcium Absorption Primarily via an Effect on Colonic Absorption in Humans1,2
The Journal of Nutrition
; Abstract Calcium absorption efficiency and bone mineral mass are increased in adolescents who regularly consume inulin-type fructans (ITF). The mechanism of action in increasing absorption is unknown but may be related to increased colonic calcium absorption. We conducted a study in young adults

The absorbing story of calcium in menopausal women
Nursing BC
; As we age, our ability to absorb calcium declines. Aging, combined with the estrogen reduction that occurs at menopause, results in an estimated 20 to 25% deterioration in calcium absorption in women from 40 to 60 years of age.3 A new study has looked at additional factors that influence calcium

Young Adolescents Who Respond to an Inulin-Type Fructan Substantially Increase Total Absorbed Calcium and Daily Calcium Accretion to the Skeleton1-3
The Journal of Nutrition
; Abstract Calcium absorption and whole-body bone mineral content are greater in young adolescents who receive 8 g/d of Synergy, a mixture of inulin-type fructans (ITF), compared with those who received a maltodextrin control. Not all adolescents responded to this intervention, however. We evaluated

Calcium Absorption from Corn Tortilla Is Relatively High and Is Dependent upon Calcium Content and Liming in Mexican Women
The Journal of Nutrition
; ABSTRACT Corn tortillas are the staple food of Mexico. During their preparation, calcium is added to the tortillas; therefore, tortillas are the main source of calcium for a large proportion of the population. The bioavailability of calcium from lime-treated tortillas in humans is not known. The
