It is necessary to eat milk and dairy products appropriately every day, such as pure milk, cheese and other dairy products, which contain a high amount of calcium and are relatively quickly absorbed, which can effectively supplement calcium.
can also increase the intake of beans and soy products, because soy products contain relatively high calcium content.
But if the diet keeps up, whether it can be absorbed is another question. Because the calcium that people eat enters the intestine, but whether it can enter the bones depends on another important thing, which is vitamin D.
There are two main sources of vitamin D: the first is to bask in the sun. The ultraviolet rays in the sun stimulate the cells of the skin to produce vitamin D. Another way is from food. However, whether it is made in the skin or the vitamin D eaten is useless, it needs further processing by our liver and kidneys to become truly active vitamin D.
Vitamin D is so important that some elderly friends start to eat vitamin D-containing health products such as cod liver oil , deep-sea fish oil, etc., as well as vitamin D-containing medicines such as alphacalcidol and rogaizan. These are of course good for bone health, but are the more vitamin D-containing health products or medicines, the better? The answer is still no.
Because the bones in our body are constantly undergoing metabolic changes, the key to determining whether the bones are hard or loose are two cells: osteoblasts and osteoclasts_ span3span.Osteoblasts are like a "construction worker", constantly "building bricks and walls" to make our bones stronger and stronger. The bones are getting looser.
The function of osteoblasts in a child's body is far greater than that of osteoclasts, so a child with immature bones slowly grows into a young man with strong bones. When you get older, things are the other way round. The function of osteoclasts in bones is far greater than that of osteoblasts, so the bones of the elderly become looser.
also needs frequent outdoor activities, because sunlight is easy to synthesize vitamin D3 , which can promote the absorption of calcium in food, and can also promote the effect of calcium supplementation. Of course, calcium supplementation should not be excessive, because excessive calcium supplementation can easily lead to the formation of stones.
With the increase of age, the elderly are prone to calcium loss and osteoporosis. If calcium is not supplemented in time, it is easy to cause fractures, and calcium supplements are needed to avoid osteoporosis as much as possible. (If the picture is infringing, please contact)
