(The dairy people hardly let us forget.) But most of us tend to liken the human skeleton to the steel framework of a building—solid, fixed, and constructed but once in the original building process. Actually, our bones are constantly changing and interacting with the rest of the body.

A person’s vitamin D status is determined by measuring 25-hydroxyvitamin D 3 levels in the blood because it reflects both the vitamin D obtained from production in the skin and that from dietary sources (see Figure \(\PageIndex{2}\)).

Milk is a particularly good source— the vitamin D, protein, and lactose in the milk promote the absorption of calcium. In the U.S., calcium intake generally is related to the amount of milk or milk products in the diet.

Plant-based alternatives often need fortification, which may be ineffective. Foods like canned fish and leafy greens also offer calcium but can have low absorption rates. Certain preparation methods enhance calcium content.

Calcium is the most prevalent mineral, mainly found in bones, while phosphorus and magnesium are more present in soft tissues. All three minerals play crucial roles as structural components of bones and regulatory agents in bodily fluids. A table illustrates their distribution in a 70 kg adult.

It highlights the types of bone—compact and spongy—and the protective layers, periosteum and endosteum. The roles of bone cells—osteoblasts, osteocytes, and osteoclasts—in bone formation, remodeling, and resorption are detailed.

Other benefits of calcium in the body include decreasing blood pressure and preventing colon cancer. Calcium blood-levels are rigorously controlled by three hormones: PTH, calcitriol, and calcitonin. The DRI for calcium intake for adults averages from 1,000–1,200 mg/day.

The Tolerable Upper Intake Level for calcium has been reduced for adults over 50 due to increased kidney stone occurrences. While dietary calcium appears safe for cardiovascular health, supplements may heighten myocardial infarction risk.

It explains the mechanisms of bone remodeling by osteoblasts and osteoclasts, highlighting the shift in balance toward resorption with age. Additionally, it mentions that the remaining 1% of calcium aids metabolic functions in soft tissues and outlines how calcium blood levels are regulated by parathyroid hormone, vitamin D, calcitonin, and other hormones.
