Calcium is the most abundant mineral element in our body, accounting for about 2% of our body weight. During childhood, adequate calcium intake can help promote growth and bone health, and it can also prevent chronic diseases in adulthood .

status of children calcium intake
2010 - 2012 China's nutrition and health status monitoring data show:
The overall calcium intake of children aged 6-17 years is insufficient, with an average of about 289.7mg/d .
Generally speaking, the dietary calcium intake of children aged 6-17 increases gradually with age, and the intake of boys is higher than that of girls, and that in cities is higher than in rural areas. However, is far below the recommended dietary intake .
data table as follows:

Chinese residents dietary recommended intake
according to " dietary reference intakes (2013 Edition) ":
| Age reference intakes |
| |||||||||
| male | t 7 ~ 10 years 1000 1000 11 ~ 13 years 1200 1200 14 ~ 17 years 1000 1000 |
As you can see, Children aged 7-18 have a calcium requirement of 1000-1200mg per day , especially adolescent children have high calcium requirements.
Studies have shown that genes affect the absorption and utilization of calcium by individuals. Such as:
VDR encodes the vitamin D receptor protein, which mediates the absorption of calcium in the intestine. Its BsmI (rs1544410) polymorphism, allele T is associated with low bone density and increased risk of osteoporosis, which may reduce the absorption and utilization of calcium.
For children whose calcium absorption and utilization are normal, follow the guidelines and get calcium from the diet. And children with low calcium absorption and utilization of gene, especially need to pay attention to adequate calcium intake , it is recommended that appropriate extra calcium is supplemented during puberty to meet the needs of fast-growing body.

The importance of calcium _strong1strong _strong1strong _strong1strong _strong1span is an important component of calcium.
Before the age of 20, it is mainly the growth stage of bone, and the bone mass continues to increase for more than 10 years. Around the age of 35-40, the bone mass per unit volume reaches its peak, which is called Peak bone degree .
Since then, bone is gradually lost, especially in postmenopausal women. If the intake of calcium is insufficient, the rate of bone loss will increase, and when the bone mass is reduced to a certain level, osteoporosis will be caused.
Therefore, long-term low calcium intake in childhood will reduce the peak bone mass that can be reached and increase the risk of osteoporosis in adulthood.

Source of dietary calcium p _strong1span _strong1strongp _span3p vegetable.
However, milk products have the best calcium absorption ,Soy products and green leafy vegetables have relatively low calcium absorption rates.
In addition, the drinking water also contains calcium. The calcium content is related to the hardness of water . The high hardness can reach 60-140mg/L, and the low hardness is below 60mg/L.
Common food content table:
is the source of 4_'s strong intake of calcium and strong for children in our country. Lead to low calcium intake .
NO.5
Milk-the best choice for calcium supplementation in milk, especially _p11span . The reasons are:
advantage
1. 100 mg of calcium in milkThe content is higher.
2. The calcium in milk is milk calcium, which is easy to absorb even when there is less gastric acid.
3. The ratio of calcium to phosphorus in milk is suitable for (2:1) is beneficial to calcium absorption. Excessive phosphorus intake will hinder calcium absorption.
4. Milk contains vitamin D, lactose, amino acids, casein phosphopeptide can promote calcium absorption. And milk does not contain factors that hinder calcium absorption.
Although there are foods with high calcium content in plant foods, plant oxalic acid, phytic acid , dietary fiber and other ingredients exist in the calcium absorption rate. Lower than the absorption rate of milk calcium.
From the four aspects of absolute calcium content, calcium absorption factor, calcium absorption factor and food intake feasibility, calcium is a high-quality calcium source superior to all foods .
NO.6
children's milk products, or pure milk, or pure milk for children?
1, drink pure milk or low-sugar fermented yogurt every day. _p11span 3 weeks old cows can drink pure milk or low-sugar fermented yogurt every day. According to the recommendations of the dietary guidelines for Chinese residents, a daily drinking amount of 300ml of milk or equivalent milk products should be reached during childhood.
If you like the taste of yogurt, it is recommended to choose low-sugar fermented yogurt. The ingredient list is mainly raw milk + probiotics. The fewer other ingredients, the better.
2, Lactose intolerant people choose Shuhua milk or low-sugar yogurt
Some children have lower lactose tolerance.Intestinal discomfort may occur after drinking large amounts of pure milk again after weaning. In this case, you can choose to drink Shuhua milk or yogurt products.
MCM6 gene rs4988235 locus
rs4988235 locus, GG is lactose intolerant type, and then drinking pure milk products after weaning _spanspanspanspans1s_GA is prone to And AA are lactose tolerant.
Lactose intolerance occurs because of the decreased ability to secrete lactase , which makes lactose unable to be absorbed by itself, and is caused by fermentation of intestinal bacteria.
Soothing milk or yogurt has removed the substance lactose, so it will not cause lactose intolerance .
3, Don’t be superstitious about children’s milk
There are a wide range of children’s milk specially made for children, including bone-building types, educational types, and so on.
This dairy product should pay attention to the following points when purchasing:
Pay attention to the added sugar content span _p1sp

0p1pThe carbohydrate in ordinary milk is lactose, and its content is about 5g/100ml. If the excess is added sugar.
Some products are 8g, some are 10g, etc. Our country's dietary guide recommends that the added sugar intake of children over 3 years old should not exceed 25g/day.
attention additives
children’s milk products contain many additives, including sodium, guarspan 3 span1 span1 span1 span1 span3 carboxymethyl cellulose Acesulfame and so on.
pays attention to beneficial ingredients
has health benefits like , iron, protein, DHA, etc. Pay attention to the amount of addition, too little will not have much effect. These beneficial ingredients can be obtained from other foods.
Suggestion: buy children’s milk,Considering the content of beneficial ingredients, additives and added sugars, try to buy low-sugar products with fewer additives. Moreover, children's milk cannot replace ordinary milk, and it is recommended to consume it only occasionally.
