Introduction which a Dietary Reference Intake (DRI) has been established by the Food and Nutrition Board. At this writing, calcium requirements are set as Adequate Intakes (AI) rather than as Recommended Dietary Allowances (RDA). The decision to set an AI rather than an RDA by the 1997 Food and Nutrition Board

Bone as the Calcium Nutrient Reserveand to make optimal use of ingested calcium. It serves both functions mainly by adjusting the balance between bone formation (which transfers mineral from blood to bone) and bone resorption (which transfers mineral from bone to blood). It is important to stress at the outset that calcium cannot gene

Nutritional Epidemiologyology, disease occurrence is measured and related to different characteristics of individuals or their environments. Exposures, or what an individual comes in contact with, may be related to disease risk. The exposure can be a habit such as smoking, which would increase an individual’s risk for lung

Clinical Approaches for Studying Calcium Metabolism and Its Relationship to Diseasedies are used to evaluate bioavailability from various sources or intrinsic calcium absorption capacity. The latter is an important risk factor for osteoporosis and possibly other disorders associated with low calcium status. The accuracy of different methods commonly used to determine fractional ca

Requirements for What Endpoint?sufficient to get an individual up to the bone retention threshold, i.e., the point at which no further increase in bone mass will occur despite further increases in calcium intake. The concept of an MDR has been largely abandoned for many other nutrients, but it remains apt for calcium, as Fig. 1 i

Botanically speaking, cereal grains are the fruit of the plant, which is the part of the plant that accumulates the least amount of calcium. Since the agricultural revolution, the main food source of calcium in the diet of most populations i

The Calcium Economyl and pearls, seashells and eggshells, antlers and bones. Because calcium salts exhibit intermediate solubility, calcium is found both in solid form (rocks) and in solution. It was probably present in abundance in the watery environment in which life first appeared. Today, seawater contains approx10
