Many official bodies give advice on desirable intakes of calcium but no clear evidence of a calcium deficiency disease in otherwise normal people has ever been given. In Western countries the usual calcium intake is of the order of 800-1000 mg/day; in many developing countries figures of 300-500 mg/day are found. There is no evidence that people with such a low intake have any problems with bones or teeth. It seems likely that normal people can adapt to have a normal calcium balance on calcium intakes as low as 150-200 mg/day and that this adaptation is sufficient even in pregnancy and lactation. Inappropriate concern about calcium intake may divert attention and resources from more important nutritional problems.
许多官方机构都针对钙的理想摄入量给出了建议，但从未有明确证据表明在其他方面正常的人群中存在钙缺乏疾病。在西方国家，通常的钙摄入量约为每日800 - 1000毫克；在许多发展中国家，发现每日摄入量为300 - 500毫克。没有证据表明摄入量如此低的人群在骨骼或牙齿方面存在任何问题。看起来正常人群即使钙摄入量低至每日150 - 200毫克也能够适应并保持正常的钙平衡，而且这种适应能力在怀孕和哺乳期甚至也是足够的。对钙摄入量的不当关注可能会将注意力和资源从更重要的营养问题上转移开。
