Proper bone development is important for all ages. A diet rich in calcium, vitamins C, A, and D, sunlight exposure, and regular exercise can promote healthy bone development. Vitamin D is crucial for calcium absorption, and exercise stimulates bone production.
Bone development is a major health issue for individuals of all ages. In infants and young children, improper bone development can lead to stunted growth, while in adults it can cause osteoporosis, a weakening of bone structure that makes sufferers highly prone to fractures. Fortunately, research has shown that there are several steps that can be taken throughout life to promote healthy bone development. These include maintaining a diet rich in calcium and vitamins C, A and D, absorbing adequate amounts of sunlight, and exercising regularly.
Calcium is perhaps the most important agent in promoting healthy bone development. This nutrient makes up a significant part of the composition of bones, giving them strength and solidity. For optimal bone health, adults should aim to consume between 1,000 and 1,200 milligrams of calcium each day. Calcium-rich foods include dairy products, beans, leafy greens like bok choy, and bone-in fish.
Several vitamins also play significant roles in healthy bone development. Among these is vitamin C, which stimulates the production of collagen – a protein present in the connective tissue of bones – and helps the body absorb calcium. Adults should consume between 75 and 90 milligrams of vitamin C per day. Citrus fruits, peppers, tomatoes, green leafy vegetables, and potatoes are all good natural sources of vitamin C.
Another key factor in bone health is vitamin A. Like vitamin C, vitamin A is thought to aid in calcium absorption. It also stimulates the production of cells responsible for building new bone. Foods rich in vitamin A include liver, egg yolks, cheese, green leafy vegetables and orange vegetables such as sweet potatoes. The recommended daily allowance of vitamin A is between 2,330 and 3,000 international units (IU). It should be noted that some research actually links excessive consumption of vitamin A to reduced bone health.
Of all the nutrients, vitamin D is perhaps the most important for calcium absorption and is therefore crucial for maintaining strong, healthy bones. Vitamin D is found in dairy products and some fish. It is also sometimes added to breakfast cereals. People under 50 should strive to get 200 IU of vitamin D each day. Because bones become more susceptible to osteoporosis with age, vitamin D intake should be increased to 400 IU by age 50 and 600 IU by age 70.
Adequate exposure to sunlight can also play a significant role in bone development. This is because the absorbed sunlight is transformed by the body into vitamin D, and can therefore prove to be a valuable alternative source of this important vitamin. Three 15-minute periods of sun exposure weekly will in most cases provide the body with the required dosage of vitamin D. It is important to note, however, that excessive unprotected sun exposure can lead to skin cancer.
Finally, exercise can also contribute to healthy bone development. Regular workouts, especially those that use weights, stimulate bone production, thus strengthening bones. This type of exercise also strengthens your muscles, creating a support system for your bones and reducing the chances of bone injury.
