What makes bones non fragile?

Calcium

* Calcium is the most abundant mineral in the human body, and it is essential for the formation and maintenance of healthy bones. Calcium makes up about 2% of a person's body weight, and 99% of that calcium is stored in the bones and teeth.

* Calcium helps to strengthen bones by combining with phosphate to form hydroxyapatite, which is the main mineral component of bone tissue. Hydroxyapatite crystals are arranged in a lattice-like structure that gives bone its strength and rigidity.

* Without adequate calcium, bones become weak and brittle, and they are more likely to fracture.

Vitamin D

* Vitamin D is also essential for bone health. It helps the body to absorb calcium from the digestive tract, and it also promotes the formation of new bone tissue.

* Vitamin D is produced in the skin when it is exposed to sunlight, and it can also be obtained from foods such as fatty fish, eggs, and fortified milk.

* Adequate levels of vitamin D are necessary for the body to properly absorb and use calcium, and without vitamin D, bones can become weak and brittle.

Other factors

* In addition to calcium and vitamin D, there are a number of other factors that can affect bone health, including:

* Age: As people age, their bones naturally become thinner and weaker.

* Gender: Women are more likely to develop osteoporosis than men.

* Genetics: Some people are more likely to develop osteoporosis due to their genes.

* Diet: A diet that is low in calcium and vitamin D can contribute to bone loss.

* Physical activity: Exercise can help to build and maintain strong bones.

* Smoking: Smoking can damage bones and increase the risk of osteoporosis.

* Alcohol: Excessive alcohol consumption can interfere with calcium absorption and can lead to bone loss.

By following a healthy lifestyle that includes adequate calcium and vitamin D intake, regular exercise, and avoiding harmful habits, you can help to maintain strong and healthy bones throughout your life.
