Two methods of measurement of fractional calcium absorption have been compared in the same individuals. There is a significant correlation between fractional 47Ca absorption as measured with a blood counting method and with an external counting method after intravenous and oral administration of 47Ca (P less than 0.001). Two varieties of the external counting method, namely with intervals of 2 h and 7 days between the i.v. and oral doses, have been compared. In a group of twenty-one patients with chronic renal failure (not on haemodialysis), 47Ca absorption as measured by external counting was significantly lower than in the control group (P less than 0.001). When put on a dialysis programme a group of six patients showed a significant increase of the fractional 47Ca absorption (P less than 0.01).

Our objective in this study was to determine the effects of a high-protein and high-potential renal acid load (PRAL) diet on calcium (Ca) absorption and retention and markers of bone metabolism. In a randomized crossover design, 16 postmenopausal women consumed 2 diets: 1 with low protein and low PRAL (LPLP; total protein: 61 g/d; PRAL: -48 mEq/d) and 1 with high protein and high PRAL (HPHP; total protein: 118 g/d; PRAL: 33 mEq/d) for 7 wk each separated by a 1-wk break. Ca absorption was measured by whole body scintillation counting of radio-labeled (47)Ca.

Background: Calcium (Ca) - fortified foods are likely to play an important role in helping the consumer achieve an adequate Ca intake, especially for persons with a low intake of dairy products. Fish bones have a high Ca content, and huge quantities of this raw material are available as a by-product from the fish industry. Previously, emphasis has been on producing high quality products from fish by-products by use of bacterial proteases.

Introduction: Recent data in morbid obesity surgery have shown that the Roux-en-Y gastric bypass results in a decrease in bone mass. Therefore, we investigated the impact of duodenal exclusion on bone mineralization in respect to newer duodenal preserving operations in morbid obesity surgery.
Methods: Twelve female minipigs underwent Billroth I (n = 6) or Billroth II (n = 6) reconstruction.
Effect of a high-fiber diet compared with a moderate-fiber diet on calcium and other mineral balances in subjects with type 2 diabetes.

Objective: High levels of dietary fiber, especially soluble fiber, are recommended to lower serum cholesterol levels and improve glycemic control in patients with type 2 diabetes. It is not clear, however, how high levels of fiber affect mineral balance.
Research Design And Methods: In a randomized crossover study, 13 patients with type 2 diabetes were fed a high-fiber (50 g total and 25 g soluble fiber) and a moderate-fiber (24 g total and 8 g soluble fiber) diet of the same energy, macronutrient, calcium, magnesium, and phosphorus content for 6 weeks each.
