Calcium: A Nutrient in Pregnancy.

Continuing education module-maternal calcium intake and metabolism during pregnancy and lactation.

Calcium is an essential nutrient during pregnancy and lactation. Calcium contributes to bone development in the fetus and neonate and is considered a critical nutrient. Physiological changes in calcium metabolism occur during pregnancy and lactation. Some women may lose some of their bone density during pregnancy and/or lactation, and then regain it after the cessation of lactation. Implication...

تأثیر پتاسیم و کلسیم بر پاسخ گلرنگ به شوری ناشی از کلرید سدیم در محیط آبکشت

An experiment was conducted in order to evaluate the effects of increased concentration of potassium and calcium in hydroponic nutrient solution on the response of safflower to salinity. The experiment was carried out in a glasshouse using a completely randomized design. Four saline treatments (Johnson solution containing 100 mM of NaCl, Johnson solution containing 100 mM of NaCl + 10 mM potass...

The effect of calcium supplementation in pregnancy on breast milk calcium concentration

Introduction: The relationship between calcium intake during lactation and breast milk calcium concentration has been studied by many investigators, but there is no conclusive evidence on the effect of supplementation during pregnancy on the breast milk content. The aim of this double blind, placebo controlled trial was to determine the effect of calcium supplementation during the third trimest...

Effects of citric and ascorbic acids, vitamin D3 and calcium on efficacy of microbial phytase in a corn-soybean meal-based diet:broiler performance and nutrient digestibility from 1 to 21 of age

Effect of reproduction on the bioavailability of calcium, zinc and selenium.

Nutrient needs increase during pregnancy and lactation to support fetal growth and milk synthesis, respectively. Physiological adjustments that are made to meet those needs alter the fraction of ingested nutrient retained, or the bioavailability. Using stable isotopes as tracers, we measured calcium, zinc and selenium homeostasis in women during reproduction. The physiological response, and the...

Association between Dietary Diversity Score and Nutrient Adequacy in Patients with Calcium Oxalate Kidney Stone

Background: Nephrolithiasis is a global health problem that is growing exponentially in the developed and developing countries. This study aimed to determine the dietary diversity score (DDS) and its association with nutrient adequacy in patients with calcium oxalate kidney stone. Methods: The present cross-sectional study was conducted on 276 male patients with calcium oxalate kidney stone. Th...
