The main causes of poor calcium absorption in humans
The importance of calcium to human health
Calcium is an essential mineral for the body. Although it only accounts for 1.5 to 2% of body weight, it plays an important role in the activities of the immune system, nervous system and muscular system. Calcium needs to be supplemented to the body depending on ages as follows:
Calcium requirement table by ages
|Age||Calcium requirement (mg/day)|
4 - 6
|7 - 9|
|Adolescent||10 - 18||1,000|
|Adult||19 - 25||700|
Adequate calcium supplementation helps us stay healthy, supports our height growth optimally and helps adults and the elderly avoid bone and joint diseases.
Calcium is an essential mineral for the body.
On the contrary, calcium deficiency or poor calcium absorption will lead to serious health problems such as physical weakness, anorexia, leg pain, cramps, etc. Prolonged calcium deficiency or prolonged poor calcium absorption will cause children to suffer from rickets, make them become shorter than their peers and cause their bones to be easily deformed.
Adults (especially old people, premenopausal or menopausal women) who are with calcium deficiency will suffer from neurasthenia, forgetfulness, mood swings and accelerated bone destruction. Prolonged calcium deficiency can cause a series of diseases such as osteoporosis, hypertension in the elderly and hypocalcemia at any age.
The main causes of poor calcium absorption
Poor calcium absorption is simply because the body cannot absorb calcium from foods into the bloodstream. According to some studies, poor calcium absorption is not a separate disease but a consequence of many different causes:
Lack of vitamin D: The factor that has a great influence on the development of the skeletal system in general and height, in particular, is vitamin D. Vitamin D is a micronutrient which plays a very important role in helping the body to absorb all calcium in intestines. Therefore, vitamin D deficiency will lead to a significant reduction in calcium absorption.
Additionally, some studies also have shown that vitamin D deficiency often occurs in people with little exposure to the sunlight, people with naturally dark skin, obesity, and people who eat less food containing vitamin D.
Vitamin D plays an important role in helping the body to absorb all calcium in intestines.
Some special kinds of diseases: Diseases are also a cause of disorders in calcium absorption, which makes calcium level in the body decline. Not only kidney diseases and gastrointestinal diseases but also many other diseases can hinder calcium absorption such as Celiac disease, colitis, pancreatitis, Crohn's disease, etc.
Foods that contain Phytic Acid and Oxalic Acid: If Phytic Acid is found abundantly in whole grains and beans, Oxalic Acid is found abundantly in vegetables such as cabbage, Chinese chives, spinach, sugar beets, etc. Calcium ions combined with acids such as Phytic Acid and Oxalic Acid will form insoluble calcium salts, which makes the body not to absorb calcium. Moreover, it is important to note that Phytic Acid and Oxalic Acid will have a more serious influence on calcium absorption if they are taken with milk.
Overly salty foods: According to the recommendations of the American Institute of Medicine, people should only eat about 1,500 mg of salt per day. Eating too much salt will cause high blood pressure, promote the excretion of minerals, especially calcium, through the urinary tract. As a result, the amount of calcium in the body is lost gradually leading to calcium deficiency.
An average person should only eat about 1,500 mg of salt per day.
Therefore, we need to get rid of bad habits that prevent the body from maximally absorbing calcium while increasing the intake of calcium-rich foods to supplement enough calcium to the body. Once calcium is adequately supplied to the body, it not only helps us stay healthy but also increases our height effectively.
Calcium deficiency can lead to weaker bones, slower growth rate and even a stunted height. According to nutritionists, the best solution is to take supplements packed with Calcium for greater bone density and rapid bone growth.
