We all know that calcium deficiency should be supplemented with calcium. The human body cannot make calcium itself, so it must be supplied from food. According to the survey in China, calcium deficiency is a very common phenomenon, especially in infants, middle school students and pregnant women. Many people have noticed this problem and started to supplement calcium tablets, but they still lack calcium. Why?
Why often eat calcium piece also can be short of calcium? Why to eat calcium piece still can be short of calcium?
It turns out that they have ignored some factors affecting calcium absorption. The absorption of calcium in intestine is mainly regulated by active vitamin D. If you don't have enough vitamin D, it doesn't help to eat more calcium tablets, because calcium can't be absorbed well. Vitamin D in the human body can be self synthesized, but there must be a prerequisite, that is to have appropriate sunlight.

If the objective conditions can not accept adequate sunlight, it is necessary to eat calcium tablets at the same time the right amount of vitamin D supplement. The absorption of calcium is also related to the acidity and alkalinity of the intestine. Acidic environment is conducive to the absorption of calcium. If you eat calcium tablets and drink soda drink or food, it will greatly affect the absorption of calcium.
The correct way is to supplement calcium and eat some yogurt, vitamin C, vinegar. Boron is a key factor in strengthening bones. Low boron diet can make a large amount of calcium excreted from the urine, unable to play its due physiological role in the human body. People can get enough boron by eating some apples, pears, grapes, vegetables and beans every day.
Phytic acid and oxalic acid are not conducive to the absorption of calcium, because they can form insoluble calcium phytate and calcium oxalate with calcium, which can not make the intestinal tract absorb calcium. These two acids are found in some cereals and vegetables, so it is better to eat calcium tablets between meals. High fat intake is also not conducive to the absorption of calcium, because a large number of fatty acids can combine with calcium to form insoluble saponification, which is discharged from the feces.
