Since becoming a mother, vitamin D is “da Bao see every day”, not to eat, is the baby can not fall a day, “or it will lack of calcium”.
From this point of view, parents do take vitamin D seriously.
In addition to know to give your baby vitamin D supplement every day, other common sense?
Well, let’s talk about vitamin D while the sun is shining.
Classification of Vitamin D:
What is that vitamin D mom and Dad always say?
It is a fat-soluble vitamin that affects the balance of our bones, intestines, immune and cardiovascular systems, pancreas, muscles, brain, and cell cycle.
It seems like everything is involved. It’s amazing, but the most important thing is to maintain a normal level of blood calcium and phosphorus, which is really important for bone health.
The most important are vitamin D2 and vitamin D3.
What’s the difference?
Yes, although the absorption in the body can be even, but the binding protein and vitamin D3 bind more closely, so, the utility of vitamin D3 is higher than vitamin D2.
At the same time, vitamin D has to be converted into active vitamin D in our bodies to work, and this is where vitamin D3 comes in:
In the cells lining our intestines, cholesterol is produced by an enzyme called dehydrogenase. Dehydrogenase — which parents don’t need to know, just what it does — converts to active vitamin D3 when the skin is exposed to ultraviolet light from the sun.
Can you make more vitamin D?
Well, it depends — skin color, age, amount and time of exposure to the sun’s ULTRAVIOLET rays, and geographic location all affect vitamin D production.
I’ll talk more about that in a minute.
Vitamin D deficiency in general?
Where does this important vitamin D come from?
Eat, not only in natural food content is very low, the amount of vitamin D in breast milk is also limited, previously, the human body to obtain vitamin D mainly by ultraviolet radiation, namely the sun, to stimulate the skin 7 dehydrogenated cholesterol into vitamin D.
How about now?
Vitamin D supplements are also an important source of vitamin D for babies.
But parents who buy a lot of vitamin D supplements still want to know if their baby is getting enough vitamin D.
In fact, parents are afraid of vitamin D deficiency rickets, which will cause the baby body calcium, phosphorus metabolism disorders, calcium salt can not be normal in the growth of bone part of the “who am I, where am I?
Then, the baby will naturally grow bone tissue mineralization is not complete, there will be bone lesions characterized by systemic chronic nutritional diseases.
Therefore, the level of vitamin D is one of the important factors affecting the baby’s bone nutrition.
So what do you think of vitamin D levels?
Most of the advice so far is that the parents will know about it by looking at serum 251 (OH)D, depending on the range (pictured above).
Let’s just sit in rows and compare them.
Taking Beijing as an example, in the survey of adolescent females aged 12-14 years old in Beijing, the average serum level of 25-1 (OH)D was only (13.4-7.5) nm OL /L in winter and 27.1± 11.nmol /L in summer.
Those with severe vitamin D deficiency were as high as 45.2% in winter and 6.7% in summer.
What about Nanjing, a little further south?
The mean was (80.5±2.3)nmoUL for children under 10 years of age and (10.5%)nmoUL for children under 10 years of age.
110 healthy babies aged 3-36 months from Changsha, Hunan province had an average of (84.4±29.3)nmol/L.
Although there are differences in dietary habits and age in the data, we can still see that in general, due to the short duration and low intensity of sunlight in the north, babies are more likely to suffer from vitamin D deficiency, so special attention should be paid to additional supplements.
How to take vitamin D supplements?
First of all, breastfeeding, formula feeding, the baby is born two weeks after the start of the recommended daily need for additional vitamin D 400IU, at least until the age of 2 years.
Premature/low birth weight, twin/multiple births were more than doubled and 800 IU/d was required.
Older children have more access to vitamin D, so where does it come from?
Say first version superpower’s favorite food, though less content of food, but also a bit, such as various kinds of egg yolk (no) in the egg white, whole milk (very low levels of vitamin D in the skim milk), fatty fish (salmon, tuna, sardine, eel, catfish, etc.), fish oil, animal liver, chicken liver, duck liver, pork liver, beef liver, lamb liver, etc.).
But cereals, vegetables, tubers, soy products and so on contain almost no vitamin D.
Small south also said before, the vitamin D content in food is very little, it is to look for a reason to oneself greedy most, so, eat food of a few vitamin D aggrandizment even, the amount of vitamin D that they contain is compared to common food want more, for instance the milk that aggrandizate vitamin D, powdered milk, biscuit.
And when parents like to take their babies out in the sun, exogenous vitamin D works just as well as endogenous vitamin D.
What you mean?
That’s the amount of vitamin D that you get from your food, which you get from the sun, works just as well in your body.
Of course, there are various vitamin preparations or drops, which I’ll skip over here.
In short, as long as the baby diet balanced and reasonable, often go out outdoor exercise, adequate supplementation of vitamin D preparation or drops, in general, will not lack of vitamin D.
What happens when you take too much vitamin D:
Parents also don’t think vitamin D is a good thing, let the baby eat more, everything too much of a good thing, moderate on the line.
If vitamin D preparation or drops intake too much, but will harm the health of the baby: long-term intake of too much vitamin D, will cause high blood calcium and high urine calcium, the baby will lose appetite, nausea, vomiting, irritability, weak, constipation diarrhea alternate.
It can also cause fever, vomiting, irritability, thirst, rashes, and occasionally other more serious adverse reactions.
Therefore, parents must add according to the amount, once the intake is too much, such as the family does not know the baby has just eaten, and to supplement, or the baby’s own hands owe to eat several, judge the baby’s excess is how much, if it is within the tolerance range, then do not add in the next few days.
In general, if the symptoms are mild, pay attention to the low calcium in the diet, it is not a problem.
Unless, for some reason, your baby is taking too much vitamin D, even more than 10,000 units, go to the hospital.
In general, in addition to following your intake, keep vitamin D out of your baby’s reach.
