Among many minerals in human body, calcium is the most abundant one. Calcium is the main component of bones and teeth. The reason why human bones and teeth have certain hardness is mainly because they contain more calcium. If the baby lacks calcium, the growth and development of teeth will be delayed and the bones will become soft. In severe cases, it can lead to O-leg, X-leg, rib eversion, chicken breast and other bone deformation. Babies are in an important period of bone and tooth growth and development, and need more calcium.
A survey of nutrition and health status of China residents in 2002 showed that the average calcium intake of children under 6 years old in China was 238.6 mg/d.
, only 33% of the recommended amount.
. Therefore, it is necessary to supplement calcium to the baby in time.
Different sources of calcium have different calcium supplementation effects and different safety factors. When parents choose calcium for their children, they should choose those with high calcium content, high absorption rate, high solubility, high bioavailability and low heavy metal content. From the current calcium market, calcium carbonate has the highest calcium content, but ordinary calcium carbonate has some shortcomings, such as poor solubility, abdominal distension and constipation after taking it, which makes many mothers give up calcium carbonate. In fact, calcium carbonate treated by advanced technology can solve these problems. For example, calcium carbonate effervescent preparation releases carbon dioxide in the process of effervescent, thus reducing the release of gas in the stomach and avoiding abdominal distension. Moreover, the solubility of calcium after effervescent is greatly improved, which solves another problem of poor solubility of ordinary calcium carbonate. In addition, citric acid in effervescent system is not only mild and non-irritating, but also can combine with calcium oxalate in urinary system.
In addition, parents should try to choose calcium supplement products specially developed for infants. Calcium preparations without sucrose are also more suitable for babies, and some fruit-flavored calcium preparations can be accepted and taken by children.
Selection of vitamin AD supplements
Infants and young children usually begin to supplement vitamin AD preparation, commonly known as cod liver oil, on/0/5 days after birth. There are many kinds of cod liver oil on the market, but not every one is suitable for infants. Infants and young children have high requirements on the dosage and method of taking cod liver oil, so parents need to choose carefully. Cod liver oil on the market can be roughly divided into two categories, one is common health care products, and the other is OTC drugs, that is, over-the-counter drugs.
Health food and medicine are two different concepts, and they are obviously different in content, examination and approval process, quality standard, production technology and medical angle. Compared with health care products,
OTC drugs are more abundant, the proportion is more scientific, and the requirements for audit are higher. Therefore,
OTC drugs are safer. The easiest way to identify OTC drugs is to look at the OTC logo on the box. Parents should choose drugs approved by the State Administration of Pharmaceutical Products, such as Yikexin.
Secondly, the ratio of vitamins A and D is also very important. The Chinese Nutrition Association suggested that vitamin A and vitamin D should be scientifically prepared in strict accordance with the ratio of 3: 1. In addition, because vitamins A and D are fat-soluble vitamins, as the name implies, they can only be absorbed and utilized by the human body if they are dissolved in oil, so vitamin AD preparations all use oil as a solvent. In addition, these two vitamins are very unstable in nature and will decompose and fail in light and air.
Shading and sealing are their basic preservation conditions. Therefore, whether the packaging is sealed and shaded can effectively protect vitamin AD from being destroyed, which is also an important selection standard.
Many mothers like to give their baby Haitao some imported cod liver oil, thinking that the quality of foreign products is more guaranteed. In fact, parents have neglected one of the most important issues. Different environments, eating habits and races have different requirements for nutrient intake, and the nutritional problems of children in different countries are also different. For example, vitamin A, vitamin D, calcium, iron and zinc are the most easily deficient nutrients for infants in China, while vitamin A deficiency in children in Europe is not common. Therefore, the extra supplement of vitamin A is not emphasized. In addition, in Japan and other coastal countries, the intake of seafood is relatively high, and the incidence of zinc deficiency will be low. Therefore, the formulas of children's nutritional preparations in different regions and countries should not be exactly the same. Choosing nutritional supplements for children depends on the overall nutritional status of China residents.
Selection of zinc supplement products for infants
Zinc is indispensable in the process of children's growth. Zinc deficiency can lead to mental retardation, slow growth, decreased taste, decreased immune function and gastrointestinal diseases. The most serious thing is that zinc deficiency will lead to the development of reproductive function of adults and affect the health of the next generation.
Infants with zinc deficiency will have the following manifestations: 1.
Loss of appetite, partial eclipse, picky eaters; 2.
Pica; 3.
Not tall; 4.
Hyperactivity, slow reaction, inattention and poor learning ability; 5.
Easy to catch a cold, recurrent respiratory infections; 6.
Oral ulcer, recurrent attack; 7, easy to diarrhea. Once zinc deficiency is diagnosed, it needs to be supplemented by drugs. At the same time, it is necessary to increase foods rich in zinc, such as meat, animal liver, eggs, milk and dairy products, nuts, seafood and so on. , can achieve ideal therapeutic effect. Food supplement alone can only play a preventive role.
Attention should be paid to the following points when selecting zinc supplements for children: 1, and zinc preparations alone are superior to compound preparations supplemented with calcium, iron and zinc in equal amounts; 2. Granule or oral liquid dosage form is more suitable for infants; 3, the therapeutic dose of zinc is
0.5- 1mg/kg, and choose zinc supplement preparation with reasonable recommended dose;
