Calcium and osteoporosis

Abstract:
Calcium is an essential nutrient that is involved in most metabolic processes and the phosphate salts of which provide mechanical rigidity to the bones and teeth, where 99% of the body’s calcium resides. The calcium in the skeleton has the additional role of acting as a reserve supply of calcium to meet the body’s […]

The relationship of dietary and supplemental calcium intake to bone loss and osteoporosis

Abstract:
Calcium supplements have become big business in the United States. The sale of calcium supplements increased sevenfold from 1980 to 1985, with +130,000,000 being spent on calcium supplements during 1985. The median daily dietary calcium intake for women in the United States is 574 mg and for men is 826 mg. The average American […]

Calcium, dairy products and osteoporosis

Abstract:
Osteoporosis is a multifactorial disorder in which nutrition plays a role but does not account for the totality of the problem. 139 papers published since 1975 and describing studies of the relationship of calcium intake and bone health are briefly analyzed. Of 52 investigator-controlled calcium intervention studies, all but two showed better bone balance […]

Calcium in Alzheimer’s disease pathogenesis: too much, too little or in the wrong place?

Abstract:
Our understanding of the molecular genetics and biochemical pathology of Alzheimer’s disease has progressed tremendously in the past decade. The metabolism of amyloid beta-peptide is being unraveled, and specific anti-amyloid therapies are now in clinical trials worldwide. The precise biophysical structure of the amyloid beta-peptide that causes neuronal dysfunction remains under investigation, as does […]

Risk of high dietary calcium for arterial calcification in older adults

Abstract:
Concern has recently arisen about the potential adverse effects of excessive calcium intakes, i.e., calcium loading from supplements, on arterial calcification and risks of cardiovascular diseases (CVD) in older adults. Published reports that high calcium intakes in free-living adults have relatively little or no beneficial impact on bone mineral density (BMD) and fracture rates […]

Reduced levels of iron, folate, vitamin B12, vitamin D, zinc, and magnesium are common in untreated celiac disease (CD) patients probably due to loss of brush border proteins and enzymes needed for the absorption of these nutrients. In the majority of patients, removal of gluten from the diet leads to histological recovery and normalization […]
