Calcium is an important element of baby development, and many parents hope that the baby can absorb as much as possible.
But calcium supplementation is more, endangering the health of children at any time!
On September 1 last year, Wenzhou News Network reported: 4-year-old girl overdosed calcium supplementation, urinary incontinence!

The Department of Traditional Chinese Medicine pediatrics of Wenzhou Hospital of Integrated Traditional Chinese and Western Medicine received a child with urinary incontinence caused by excessive calcium supplementation.
The little girl is 4 years old this year, because of the lack of sleep in the first few months, the father consulted an "expert" on the Internet, saying that the child is not enough calcium supplementation, let the child strengthen the supplement of calcium.
Therefore, Dad began to add calcium to Xiaozhen according to the doctor's requirements.
The calcium that I ate every day continued to eat, the vitamin D increased from one a day to two, and the amount of milk drunk also doubled, so it was supplemented for three or four months.
Suddenly, one day, Xiao Zhen was incontinent, always peed on her pants during the day, and wet the bed at night. Parents bought some medicine for their children to eat for a few days, but it was still not good.
Went to the hospital for a check, the results showed high urinary calcium. The doctor said that the calcium supplement was overdose, and the whole family was dumbfounded.
The case of pitting the baby because of excessive calcium supplementation is actually more than this one.
A 1-year-old baby girl in Meizhou, Guangdong Province, was sent to the hospital for emergency treatment because of excessive calcium supplementation, resulting in severe hematuria.
Doctors said that the baby girl found stones in many places, and there were different degrees of hydronephrosis, and there were signs of damage to kidney function.
Baby girls are premature babies, and there is a difference in height and weight compared to babies of the same age.
Parents catch up with the baby's development and give the baby crazy calcium supplementation, but they do not realize that the original excessive calcium supplementation will also cause accidents.
Many parents are anxious about the baby's calcium deficiency, but in fact, most of the babies who have enough milk and maintain a balanced diet do not need additional calcium supplements.

Taking a baby within 6 months as an example, he only needs to drink 300ml of milk per day to consume enough calcium for one day, and most of this milk can be easily achieved by the baby.
So why are there still calcium deficiencies in babies?
That's because it's very likely that the calcium that your baby just ate on the front foot was stolen from the back foot by these "calcium-stealing" foods.
1
Foods that steal calcium
High in oxalic acid
Oxalic acid binds to calcium ions in the intestine to form an insoluble calcium oxalate precipitate that affects calcium absorption.
Because of the presence of oxalic acid, some ingredients have a high calcium content, but the calcium absorption rate is relatively low, such as spinach, which has a high calcium content, and the absorption rate is only about 1/10 of the milk.
If you want to eat these vegetables and avoid the effects of oxalic acid on calcium absorption, you can blanch the ingredients in water before formal cooking, which can remove most of the oxalic acid.
02
High content of phytic acid
Similar to oxalic acid, phytic acid also traps calcium ions in the intestine, combined to form a precipitate of calcium magnesium salts of phytate, which also affects the absorption of calcium.
Most dried beans are rich in phytic acid, so compared with the calcium absorption rate of milk, the calcium absorption rate of dried beans is only about 1/2 of milk.
However, the phytic acid of fermented soy products will be greatly reduced, so some soy products, such as non-lactone tofu, are good calcium supplements!
03
Dietary fiber content is high
Dietary fiber contains a variety of acidic groups such as glucuronic acid, which are ionized into negative electricity in the gastrointestinal tract and bind to metal calcium ions with electrostatic ion bonds or coordination bonds to form complexes, thereby affecting calcium absorption.
04
Phosphorus content is too high
The optimal ratio of calcium and phosphorus in the human body is 2:1, calcium and phosphorus complement each other, but also contain each other, how much phosphorus content we consume daily will affect the absorption of calcium.
Too much phosphorus will promote the precipitation of calcium and phosphorus compounds in the intestinal lumen, and long-term intake of too much phosphorus will damage the balance mechanism of calcium and phosphorus, change calcium metabolism, and affect calcium absorption.
05
High in grease
Excessive fat intake can lead to a large amount of fatty acids and calcium combined to become insoluble calcium soap calcium, which is excreted from the feces, which will not only affect calcium absorption, but also lead to discomfort such as hard stools.
How to Promote Calcium Absorption?
vitamin d
Vitamin D promotes calcium absorption and transport in the small intestine, promotes tubular reabsorption of calcium and phosphorus, maintains blood calcium concentration and promotes ossification, and regulates blood calcium balance.
Because vitamin D plays a vital role in calcium absorption, the Dietary Guidelines for Chinese Residents recommend that 400 units of vitamin D need to be supplemented daily from 15 days after the baby is born.
But relying on food alone to supplement vitamin D is too difficult! We roughly calculated:
Therefore, in order to allow the baby to consume the sufficient amount of vitamin D needed for development, whether it is exclusive breastfeeding or formula feeding, it is necessary to supplement the baby with additional vitamin D.
Proteins and amino acids
When dietary protein is sufficient, amino acids will bind to calcium into soluble complexes, which are more conducive to calcium absorption.
Dairy products, fish, poultry, eggs and lean meats are all sources of high-quality protein.
lactose
Lactose can form soluble low molecular weight complexes with calcium, increase the concentration of free calcium ions, and promote passive diffusion.
Breast milk, milk, bread, etc. are all lactose-rich foods.
We found the culprit of "stealing calcium", just to understand the principle of nutrient absorption, not to say that we want to kill them all.
Although "stealing calcium" food will affect calcium absorption, it is not useless.
The director always advocates that babies should maintain a balanced diet, rather than staring at a certain nutrient for supplementation, or expecting to supplement nutrition through a single food.
If parents have no concept of what the baby should eat and how much to eat every day, they can follow the following dietary pagoda chart to buy vegetables, which can basically ensure the baby's daily nutritional needs:
★ Within 6 months of age
Source: Chinese Nutrition Society
★ 7-24 months of age
★ 2-5 years old
Again, a balanced and varied diet is the basis for ensuring the healthy growth of children.
