Food can be an excellent source of calcium. Dietary calcium is in general as well absorbed as calcium supplements, and exerts the same effects on bone. The main sources are dairy products, but also some vegetables and fruits contain considerable amounts of calcium. Mineral water can serve as a supplement. Cross-sectional, longitudinal and some interventional trials have shown positive effects on bone metabolism, bone density and bone loss. But the effect on fracture incidence is less certain, and that of milk, the most studied dairy product, still unproven.
食物可以是钙的优质来源。膳食钙一般与钙补充剂的吸收效果一样好，并且对骨骼产生相同的作用。主要来源是乳制品，但一些蔬菜和水果也含有大量的钙。矿泉水可作为一种补充。横断面研究、纵向研究以及一些干预性试验均已表明，其对骨代谢、骨密度和骨质流失有积极作用。但其对骨折发生率的影响尚不确定，而对研究最多的乳制品牛奶而言，其效果仍未得到证实。
