Is high calcium milk more calcium supplementation?

the
: calcium supplementation should drink high calcium milk, because high calcium milk contains more calcium, calcium supplement effect is better.truth:so-called high calcium milk, as the name implies is a higher calcium content of milk. Many people may think, the same milk, why high calcium milk calcium more? In fact, the raw materials of high calcium milk is also ordinary milk, only in the production time, artificially add some extra calcium, which makes high calcium milk in the calcium content is higher. Although we usually call it high calcium milk, however, it actually has a more professional name: "calcium-fortified milk".so-called fortification, in nutrition is to supplement a certain nutrient in a food, and such food is called "nutritional fortification food". There are many such "nutritional fortified foods" in life, such as iodized salt, iron soy sauce and so on. High calcium milk is the milk of calcium "enhanced", in fact, is also to milk "calcium supplementation."many calcium-containing substances can be added to high calcium milk as calcium agents, such as calcium carbonate, calcium lactic acid, calcium phosphate, calcium lactate, calcium citrate and so on. At present, calcium carbonate and calcium milk are used more.High calcium milk, high limit high calcium milk added calcium is also limited, to add a large amount of calcium to the milk, is actually a very technical difficult thing, it is easy to destroy the stability of the protein system, affecting taste and sterilization stability.Milk itself is already a high calcium food, in which protein and calcium have a delicate balance, like sitting in a car, each position corresponding to a calcium ion, they sit in a stable and orderly position, if this time came a group of other calcium, will certainly break this balance, some people have no seat to sit. The casein rich in milk is very sensitive to calcium ions, and adding calcium agents can cause bridge-link flocculation between casein in the milk milky interface, which can lead to problems such as precipitation and milk analysis. Some studies have found that when calcium carbonate is used, when the amount of calcium carbonate is added in 0.5 to 2.0, or when the amount of calcium added in milk is 0.5 to 1.5, the precipitation in high calcium milk gradually increases, and, with the extension of preservation time, this precipitation will increase further.addition, China's national standard GB14880-2012 "food nutrition fortizer use standard" also has strict requirements for calcium addition, which is based on China's residents needs and risk assessment results. On the one hand, to avoid adding too little does not increase the calcium content of the purpose, on the other hand, but also to avoid adding too much affect the taste, and the body is not easy to absorb., enterprises in the production of high calcium milk, "calcium" is not how much can be added.does high calcium milk have?, the calcium content per 100 milliliters of regular milk is about 90 hawker-120 mg. So what kind of milk can be called "high calcium milk"? According to China's latest nutrition label standards in the "content claims" provisions, calcium content reached or higher than a certain value (30% NRV, that is, about 120 mg / 100 ml) can be called "high calcium milk" .But in 2008 researchers investigated the calcium content of several common brands of high calcium milk and ordinary pure milk, and found that the calcium content of high calcium milk was only a little higher than that of pure milk, for example, for every 100 milliliters of milk, brand 1 pure The calcium content of milk is 79.2 mg, while the calcium content of its high calcium milk is 81.2 mg, and the calcium content of brand 2 pure milk is 97.3 mg, and the calcium content of high calcium milk is 107.4 mg. It can be seen that many products called high calcium milk, its calcium content and ordinary full-fat milk gap, not necessarily can reach more than 25%, compared with ordinary skimmed milk, not so big gap., nutrition labels were not implemented at the time, and the dairy market was chaotic. With china's national standard GB28050-2011 "prepackaged food nutrition label general rules" in January 1, 2013 the official implementation of China's label similar to "high calcium", "high-speed rail" and so on have specific requirements, that is, must reach a certain content in order to do the corresponding "claim." Recent surveys of the market by several departments have also shown that high calcium milk can basically meet the standard requirements, its claims are basically "real".Milk high calcium, no need to "calcium supplementation some people think that the calcium content of high calcium milk is always a little more than other milk, drink the same amount of milk, high calcium milk to obtain more calcium, calcium supplementation will be better. In fact, milk itself is a high calcium food, and the absorption rate of calcium in milk is also very good, artificial milk "replenishment" of calcium is not large, absorption is not ideal.milk is a champion of calcium supplementation in food. On the one hand, it contains high calcium, calcium content per 100 ml of milk is usually about 100 mg /100 ml, drinking a glass of 250 grams of milk can obtain about 250 mg of calcium, equivalent to 1/3 of the day required. In addition, calcium in milk is very easy to be absorbed by the human body, milk calcium 1/3 to free state, can be directly absorbed, and another 2/3 of calcium binding on casein, this part of calcium will be digested with casein and released, it is easy to be absorbed. The absorption rate of artificially added calcium is very low. Affected by the cost, most of the high calcium milk is now added calcium carbonate, this calcium absorption effect in the human body is not ideal.Conclusion:high calcium milk calcium content is indeed higher than ordinary milk, but the milk itself is rich in calcium, the increase in this part of the "calcium" amount does not cause a huge difference, and most of the absorption effect is not as good as the milk itself calcium. Adults in addition to a normal diet, half a kilo of ordinary milk per day, coupled with green leafy vegetables or tofu and other high calcium food, can meet the daily calcium needs. There is no need to buy high calcium milk deliberately.
