Excess Dietary Protein And Calcium
1,202 words... sodium in the water surrounding it. Ninety-nine percent of the calcium is in bone. Bone responds to acid by chemical reactions with the rapid release of carbonate, citrate, and sodium from the hydration shell (Barzel 1051). Therefore, in response to chronic acid stress such as an acid-ash diet, cellular responses mobilize bone and calcium as a buffer. As the result, more calcium will be reserved from bone, and excreted in urine. The effects can be mild in temporary cases, such as hypercalciu...
