[Metabolic alterations triggered by low calcium diets].
Calcium is essential for bone and tooth formation, achievement of optimal peak bone mass and also for regulation of physiological processes. The calcium demand depends on age, gender and different physiological processes. These requirements are higher during childhood, pregnancy and lactation. Dietary Ca2+ deficiency modifies Ca2+ homeostasis and the metabolism of calciotropic hormones and increases the efficiency of intestinal Ca2+ absorption and renal reabsorption, altering bone metabolism. The low Ca2+ diet is associated with hypertension and risk of cancer.
