When is the best time for baby to take calcium supplement? Parents can distinguish according to the baby's growth and development. Generally, the best time for baby to take calcium supplement is when the baby has early symptoms of calcium deficiency, such as night sweats, night terrors, night crying, pillow rubbing and baldness, or when the baby has stunted growth, such as the baby can't look up after 2 months, can't turn over after 4 months, can't sit unsteadily for half a year, can't climb for 7 or 8 months, and can't stand when he is almost one year old. These manifestations indicate that the baby has calcium deficiency, and calcium supplementation is the best at this time.
It is best to supplement calcium several times a day, at or after three meals. Because the absorption of calcium is at its peak at night, taking it after dinner has the best effect. The so-called "good calcium supplement effect at night" is because the old bone tissue is constantly eliminated at about 3 am, so it is suitable to supplement calcium source at night to ensure the calcium index in the body is more stable. Be careful not to eat dinner too late, so as not to form urinary calculi.
Some experts pointed out that the best time to supplement calcium is before going to bed every day. In the diet of three meals a day, the human body can take in 300 mg ~ 400 mg or even more calcium from food. When the body excretes calcium from urine through the calcium regulation mechanism, the blood can be supplemented from food at any time to maintain the blood calcium level. At night, the human body stops eating, but urine will form as usual, and some calcium in the blood will continue to enter the urine, so in order to maintain the normal blood calcium level, the human body has to use the calcium pool, that is, the calcium in the bones. Supplementing calcium before going to bed can provide calcium source for this calcium regulation at night and block the use of bone calcium in the body. Moreover, calcium also has a calming effect and can help sleep.
Calcium is an insoluble mineral. Even if a large amount of vinegar is added in the cooking process, the calcium content in bone soup is almost negligible. Therefore, no matter what method is adopted to cook bone soup, the calcium content in it is far from reaching the goal of supplementing calcium.
The calcium content in bone soup is very small, and the calcium content in pig bone soup made from 10 kg of ribs is less than 150 mg. It has been tested that a bowl of bone soup contains about 2~3 mg of calcium. Then, according to the daily requirement of 800 mg of calcium for adults, it takes about 300 ~ 400 bowls of bone soup to meet the calcium requirement of human body, which is huge.
After a long time of stewing bone soup, the fat in the bone was completely stewed and dissolved into the soup, which made the fat content in the soup rise linearly. In this way, drinking bone soup in large quantities can not only achieve the effect of supplementing calcium, but may lead to excessive energy intake, which is not conducive to health.
