How Is Bone Mass Measured?
Bone mass refers to the content of bone tissue [bone minerals (calcium, phosphorus, etc.) and bone matrix (bone collagen, protein, inorganic salts, etc.)] per unit volume. Bone mass is used to represent the health of the bones. Human bone mass is different at different ages. Increasing bone mass requires not only calcium but also collagen.

- Bone mass refers to the content of bone tissue [bone minerals (calcium, phosphorus, etc.) and bone matrix (bone collagen, protein, inorganic salts, etc.)] per unit volume. Bone mass is used to represent the health of the bones. Human bone mass is different at different ages. Increasing bone mass requires not only calcium but also collagen.
- Many people now use bone mass to describe and represent bones, especially the thickness of the limbs. If you look at the bone mass in the strict sense, it is very important for any vertebrate, whether they are old or young. For people, today we have discovered that bone mass is related to heredity, nutrition, exercise, sunshine, and health.
- Bone nourishment
- Relationship between bone strength and bone mass
- The strength of human bones is closely related to the amount of bone.
- Bone calcium content is different at different ages in a lifetime. At birth, the body's calcium content is only 25 grams, and the calcium content in adults can reach 12 hundred grams. The bone mass of people around 30 years of age has reached a peak in life. From 50 years of age, the average bone loss is 0.5% to 1%. On average, women lose 3% to 5% of their bone mass each year. Women's bone loss eventually reaches 30% to 40% of peak bone mass, and men lose 20% to 30%. Therefore, the peak bone mass is like the "bone bank" in the human body. The higher the peak bone mass in young people, the more "savings" in the "bank", the more bone mass that people can consume in the future. The amount of peak bone mass is mainly determined by genetic factors, nutritional status, and living habits. Adequate supply of calcium during the child's growing season and women's pregnancy and lactation, adults to overcome bad habits (such as smoking, drinking, etc.), and strengthen weight-bearing exercise can increase the "bone bank" bone mass reserve.
- When people reach old age, due to the decline in the function of tissues and organs in the body, the reduction of various hormone secretions, and the disorder of bone metabolism, the absorbed calcium cannot compensate the excreted calcium, and the body is in a state of negative calcium balance. At this time, in order to ensure the normal functioning of physiological functions, the system responsible for calcium metabolism in the body will use the calcium in the bone bank to maintain the blood calcium balance.
- Increase bone mass, not just calcium
- In daily household foods, milk, cheese, eggs, soy products, kelp, laver, shrimp skin, sesame, hawthorn, sea fish, vegetables, etc. are more calcium-containing, especially milk. 120 mg of calcium per 100 grams of fresh milk If you drink 250 grams of milk per person per day, you can provide 300 mg of calcium; drink 500 grams of milk every day, you can provide 600 mg of calcium; plus about 300 mg of calcium provided by other foods in the diet, you can fully meet The human body needs calcium. It is worth noting that when eating these calcium-rich foods, you should avoid eating too much phosphate-rich and oxalic acid-rich foods, so as not to affect the absorption of calcium.
- But the increase in bone mass can be achieved by more than just calcium supplementation. Collagen is an important component of human bones, especially cartilage tissue. Collagen is like a small hole-filled net in the bone, it will firmly retain the calcium that will be lost. Without this net full of small holes, even if it is supplemented with excessive calcium, it will be lost in vain. And the characteristic amino acid of collagen, hydroxyproline, is a tool for transporting calcium to bone cells in plasma. Therefore, when calcium is added, collagen must be added to achieve the purpose of increasing bone mass.
