The Comprehensive Guide to Bone Mineral Density and Health

The Fundamental Understanding of Bone Mineral

Bone mineralization is of utmost importance when it comes to our overall health. Our skeletal system, which encompasses the bone mineral, significantly influences our vitality, strength, and functional abilities. Bone mineral has a key role in the structure and rigidity of our bones, thus making it a subject worthy of comprehensive exploration.

Detailed Survey of the Bone Mineral Structure

Delving into the structure of the bone mineral, it is fascinating to understand that it majorly consists of a mineral known as hydroxyapatite. This is an intricate compound primarily made of calcium and phosphate. These two elements bond to form crystals which provide the bone with its hardness and strength.

Around 70% of the weight of a bone is all due to hydroxyapatite, with the remaining being made up of collagen, water, and other proteins. This complex structure ensures every bone in our body serves the purpose it was intended for.

The Necessity of Bone Mineral in Body

The importance of bone mineral cannot be overstated. Here’s why it is crucial for our body:

  1. Structural Support: The bone mineral, with its unique blend of rigidity and flexibility, gives the body its shape and form. It thereby acts as an internal support.

  2. Facilitates Mobility: Bone mineral aids in the mobility by providing strong and rigid points of attachment for the muscles.

  3. Shielding Delicate Organs: It shields the fragile body organs like brain, heart, and lungs by forming a protective barrier.

  4. Reservoir for Minerals: Bones serve as a reservoir for minerals such as calcium and phosphorus, playing an essential part in mineral homeostasis in the body.

Factors that Influence Bone Mineral Density

Bone mineral density (BMD) is a measurement that refers to the amount of mineral matter per square centimetre of bone. Various factors influencing bone density include age, genetic attributes, hormonal levels, physical activity, and nutrition. An imbalance in any of these factors can put a person at risk of developing bone health issues such as osteoporosis.

Role of Nutrition in Bone Mineral Health

When talking about nutrition and bone health, it’s essential to single out certain nutrients that play a pivotal role in bone mineral health.

  1. Calcium: This is crucial for the bone’s structure and function. Besides dairy products, it can be found in almonds, leafy green vegetables, and fortified foods like orange juice and cereals.

  2. Vitamin D: It aids in the absorption of calcium from the food into the body. The primary source of Vitamin D is sunlight, and it can also be found in foods like fatty fish, cheese, and egg yolks.

  3. Phosphorus: Other than being a critical component of the bone mineral itself, Phosphorus works in tandem with calcium in bone health. It’s found in protein-rich foods such as meat, poultry, dairy products, beans, and nuts.

The Impact of Exercise on Bone Mineral Density

Resourceful exercise and physical activity can also greatly influence bone mineral density. These activities apply a certain amount of stress to the bone, which then responds by thickening and strengthening itself.

Activities that prove beneficial include:

  1. Weightlifting: This involves resistance training that exerts pressure on the bones, leading to increased bone density.

  2. Aerobic activities: Walking, jogging, and climbing stairs can improve overall body fitness and bone health.

Evaluation and Enhancement of Bone Mineral Density

The evaluation of bone density can be accomplished through medical methods, one of them being a DXA scan, Dual-energy X-ray absorptiometry. A lower than average BMD indicates a risk for fractures, which may be a sign of osteoporosis.

Preventing bone health issues involves incorporating a combination of a balanced diet rich in calcium and vitamin D, regular exercises, and routine assessments of bone mineral density. Making lifestyle changes such as quitting smoking and limiting alcohol intake can also contribute to improving bone health.


Understanding the essential role of bone mineral in the body is important in taking steps towards maintaining and enhancing overall bone health. With the right lifestyle choices, we can ensure the upkeep of the bone mineral density in the long run.
