Background: Elevated serum calcium has been associated with a variety of metabolic abnormalities and may be associated with a greater risk of diabetes.
Although high calcium intakes have long been recommended to prevent osteoporosis, there is little evidence that high calcium intakes effectively prevent fractures. Osteoporotic fractures are, like ...
A high calcium intake, mainly from dairy products, may increase prostate cancer risk by lowering concentrations of 1,25-dihydroxyvitamin D3 [1,25(OH)2D3], a hormone thought to protect against prost...
Intake of carbonated beverages has been associated with increased fracture risk in observational studies. The usual explanation given is that one or more of the beverage constituents increase urina...
The digestibility of cocoa butter was reported in animal but not human studies to be low (60–70% and 89–94%, respectively). These differences could be due to the much higher ratio of calcium to fat...
It must be a source of some surprise to rational scientists that the human requirement for calcium, an apparently inoffensive nutrient that contributes so much to our physical stability, arouses st...
A recent task force of The American Society for Clinical Nutrition and American Society for Nutritional Sciences recommended in a position paper on trans fatty acids that models be developed to ass...
To achieve adequate dietary calcium intake, several choices are available that accommodate a variety of lifestyles and tastes. Liberal consumption of dairy products in the diet is the approach of m...
The potential benefits of increasing calcium intake in small children must be balanced with the potential risk to iron utilization from high calcium intakes.
The absorption efficiency of calcium in humans is low. Some studies in infants have shown that calcium absorption can be increased by adding medium-chain triacylglycerols to the formula diet.
Although additional dietary calcium is recommended frequently to reduce the risk of lead poisoning, its role in preventing lead absorption has not been evaluated clinically.
The title and conclusions of the article, “Bioavailability of iron glycine as a fortificant in infant foods,” by Fox et al (1) are not supported by the data presented. Their data show that the abso...
