Abstract:

Rats deprived of dietary calcium increase voluntary intake of NaCl solutions. We investigated whether the major hormones controlling calcium homeostasis are responsible for this increase in salt intake. Removing endogenous sources of calcitonin and parathyroid hormone by thyroidectomy and/or parathyroidectomy had no effect on NaCl intake. The surgically compromised rats and their intact controls drank similar amounts of NaCl in response to manipulations of diet calcium content. Despite normal NaCl intakes, rats with parathyroidectomy had low plasma calcium concentrations and a strong appetite

Abstract:

Calcium intake and its association with dieting behavior were assessed in female adolescents competing in an aesthetic and a nonaesthetic sport (gymnastics and speed skating). Athletes were 25 skaters and 32 gymnasts competing at a provincial level or higher. Calcium intake was assessed by food frequency questionnaire; dieting behavior by the Eating Attitudes Test Dieting subscale; and body composition by skinfolds, height, and weight. Mean calcium intakes of both groups of athletes exceeded Canadian recommendations, and skaters' mean intakes exceeded U.S. recommendations; however, many indivi

The objective of this study was to determine trends in calcium intake from foods of Canadian adults from 1970–1972 to 2004. We compiled the calcium intake of adults (aged ≥19 years) from foods from Nutrition Canada (1970–1972; n = 7036); 9 provincial nutrition surveys (1990–1999; n = 16 915); and the 2004 Canadian Community Health Survey 2.2 (n = 20 197). Where possible, we used published confidence intervals to test for significant differences in calcium intake. In 2004, the mean calcium intake of Canadians was below Dietary Reference Intake recommendations for most adults, with the greatest

Abstract:

ABSTRACT Background Nutritional rickets is believed to result from the interaction of inadequate serum 25-hydroxyvitamin D [25(OH)D] concentration and dietary calcium intake, but this interaction has not been confirmed in children with rickets. Determining the vitamin D requirements to prevent nutritional rickets has been thwarted by inconsistent case definition, inadequate adjustment for calcium intake and other confounders, and 25(OH)D assay variability. Objectives To model the 25(OH)D concentration associated with nutritional rickets in calcium-deprived Nigerian children, adjusted for confo

Abstract:

Promoting calcium intake is a cornerstone for osteoporosis management. Some individuals limit dairy product consumption, a major calcium source, due to their high content in saturated fats and their perceived negative impact on lipid profiles. This study explored the associations of calcium from various sources with blood lipids in community-dwelling elderly (n = 717) from the GERICO cohort. Dietary calcium intake was assessed at several timepoints using a validated food frequency questionnaire (FFQ) and calcium supplement use was recorded. Blood lipids were treated as categorical variables to

The aim of the present study was to investigate the relationship of Ca intake and serum Ca levels during the third trimester of pregnancy with levels of the same mineral in transition milk (days 13−14 of lactation) and mature milk (day 40 of lactation). The study subjects were a group of fifty-seven healthy, lactating mothers aged between 18 and 35 years (mean 27 (SD3·7) years) whose pregnancies and labour were attended by the Department of Obstetrics and Gynaecology of Cuenca INSALUD Hospital, Spain. Ca intake during the third trimester was determined by recording the consumption of foods ove

Abstract:

Calcium accounts for 1–2 % of adult human body weight. Over 99 % of total body Ca is found in the teeth and bones. Therefore, in addition to the obvious structural role of the skeleton, it also serves as a reservoir for Ca. Dietary Ca intake has an important impact on bone metabolism and bone health. Chronic Ca deficiency resulting from inadequate intake or poor intestinal absorption is one of several important causes of reduced bone mass and osteoporosis. It is vital, therefore, that adequate dietary Ca is consumed at all stages of life — in early life so that the genetically programmed peak

ABSTRACT Background In light of the publications (2008–2014) linking calcium intake, mainly from supplements, to the elevated risk of cardiovascular events, there is a need to determine if there have been any changes in usual intakes of calcium among Canadians. Objective We aimed to examine changes in dietary and total usual intake of calcium among Canadians aged ≥1 y over the period 2004–2015. Methods We used nutrition data from 2 nationally representative surveys conducted in 2004 and 2015 (CCHS 2004 Cycle 2.2 and CCHS-Nutrition 2015).

Abstract:

Dietary protein has several opposing effects on Ca balance and its net effect on bone is not well established. It has long been recognized that increasing protein intake increases urinary Ca excretion. More recently, it has been observed that increasing dietary protein raises the circulating level of insulin-like growth factor-1, a growth factor that promotes osteoblast formation and bone growth. Other effects of protein on the Ca economy have been suggested in some studies, but they are less well established. Several studies have examined associations between protein intake and bone loss and

Forty adults Wistar rats were ovariectomized or laparotomized. METHODS: The animals (n=40) were randomly placed in eight groups receiving the AIN-93 diet with 100% or 50% of the recommended calcium intake with or without added caffeine (6mg/kg/day). The animals were kept in individuals metabolic cages at a temperature of 24°±2ºC, light/dark cycles of 12/12 hours, and deionized water available ad libitum.
