[Role of calcium intake in obesity].
Recent evidences from epidemiological and intervention trials suggest that a higher calcium intake is associated with a lower body weight and a reduction in total and central body fat. The potential role of calcium intake in the regulation of body adiposity has been explained by the intracellular calcium, which is able to promote adipocyte fat accumulation by exerting a coordinate regulation stimulating lipogenesis and suppressing lipolysis. Moreover, the intracellular calcium has been implicated on the etiopathogenesis of hypertension, insulin resistance and dyslipidemia, appearing as a potential common substrate in the metabolic syndrome. Dietary modulation of intracellular calcium through calciotropic hormones opens an exciting possibility to prevent and tackle obesity and its associated complications by increasing the calcium intake. However, available evidences are mostly indirect and further studies specifically designed for this purpose are needed.
