Enrich the calcium and drink the milk and not so good as eating the vegetables? The milk is drunk to lack calcium?
At one time, rich upper these drink the intersection of milk and " the notice " a little Transmitted everywhere, many people half a letter and half a query: Is this true? The shell network " The pulverizer of the rumour " Have carried on this lame speech " Strike back " .
Drink the milk and enrich the calcium and not so good as eating dishes?
What is the truth on earth? Tell first that enriches the calcium. Enrich the calcium, mainly mean that enriches bone calcium, there is 99% calcium that exists in the human body in the skeleton, various biochemistry that other 1% participate in the human body react. The course of enriching the calcium depends on three factors: Intaking amount, absorption rate, biological utilization ratio.
See the calcium content simply, 100 grams of milk include calcium about 110 milligrams, really cannot be regarded as highest in various food, calcium content of some marine alga, the small fish shrimp done, the sesame,etc. is higher than the milk. But should know, 90% are water in the milk and if remove these some water, its content of calcium can be improved and is close to 10 times.
1/3 calcium exists with the free attitude in the milk, can be absorbed directly; Other 2/3 calcium is combined on casein, this part of calcium will be released out with caseic digestion, also very easy to be absorbed; Finally, the biological utilization ratio of calcium in the milk is very high too. When absorbing the proportion of calcium and phosphorus between 0.5 and 3 at the same time, what calcium is kept on the bone is the most effective. And the proportion of calcium and phosphorus is in 1.3 in the milk. Can find out, the milk is really rare fine calcium source in human meal.
As for the vegetables, the calcium content without a lot of vegetables is higher than the milk at first. Secondly, contain oxalic acid in the most vegetables, and oxalic acid will reduce including calcium a lot of mineral and absorption of microelement, make the absorption rate of calcium in the vegetables much lower than the milk. The absorption rate of calcium is only 1/6 of calcium in milk such as the spinach. An only wonderful work in the vegetables, it is the cabbage. Absorption rate and milk of calcium in the cabbage are high equally, but calcium content among them is only 30 milligrams per hectogram. That is to say, if you insist on enriching the calcium by eating the cabbage, others only need to drink 300 ml of milk or eat 30 grams of cheese to take in 300 milligrams of calcium in the morning, and you must eat one kilogram cabbage!
Drink milk calcium and run off instead?
Rumor is mentioned, once drink the milk or may cause humorally to become sour when eating carnivorously, then bone calcium will release, come out, neutralize acid. So draw the conclusion and say: Drink the milk, calcium has been run off instead.
Such a statement does not have scientific basis at all.
First of all, cause humorally to turn into the main " arch-criminal " of the acid It is a hydrogen ion. The source of the hydrogen ion is mainly dissolved in carbonic acid that water produces hydrogen root and hydrogen ion of carbon dioxide that carbohydrate metabolism is produced in the human body, this is called breath acid.
And, the organism under the health condition has a set of intact mechanisms, can keep being humoral within the range of a normal tingling alkali, a normal food which healthy persons will not take in leads to the fact humoral sour alkali is out-of-balance, will not result in decomposing bone calcium.
Secondly, human skeleton to increase or reduce, depend on, build the intersection of bone and cell and lose the intersection of bone and cell act on commonly in total amount. Usually from born in the stage to teenagersing, making bone cells plays a leading role, the human skeleton will be thickened and changed densely. By about thirty or forty years old, the human skeleton weight peaked, later lost bone cells got the upper hand, because of the reason of hormone after the human body runs off osseous (women climacteric slowly, osseous to run off the speed faster than men) ,Cause osteoporosis finally.
And as it always goes, " It will cause osseously to run off to take in the acid food of the content of high protein " On the contrary, a large number of research shows, improve the intaking amount of protein, no matter animal albumen or plant albumen, neither will cause bone calcium to run off osteoporosis, help the skeleton to be healthy instead. Because protein that takes in will stimulate the production of insulinogenic growth factor IGF-I, this kind of factor can stimulate the skeleton to take shape, increase the bone weight.
So we can in the intersection of teenagers and the intersection of period and " deeply cut hole, accumulate the grain while being wide " on one hand ,It is osseous by dealing with the osseous loss in the future to store enough one, on the other hand can even try hard to maintain the density of blood calcium after the middle age, thus slow down the osseous speed that runs off.
Conclusion: The milk is rare high-quality calcium source, there is higher calcium content, the calcium among them is very easy to be absorbed and utilized by the human body. Contrary to what the rumor speak, it not only will not cause the calcium deficiency to drink the milk or eat the dairy products, contribute to increasing the bone weight instead, prevent osteoporosis.
The food science in Zhejiang University and department's Deputy Director's bright red of the nutrition add a professor to think
It drinks milk to be many and kind
Entanglement enrich the calcium about milk, have several little rumour, little to arrange, interview the expert of our province also yesterday, crush it at one blow.
Zhejiang University's food science and department's Deputy Director's bright red of the nutrition added a professor to emphasize his view: "The milk is the best food that the human body enriched the calcium, this is undoubted. " Professor Zhu explains, because contain lactose in the milk, it can promote the effective absorption of the calcium.
Still say on the net, the Chinese stomach is unsuitable to drink the milk, true? Professor Zhu thinks, this and ethnic group's nothing relation. Suitable for drinking the milk, seeing the human body will tolerate lactose. Because there is lactase in the human body, can decompose and absorb lactose in the milk. Keep the frequency of certain absorption milk, would not lose this kind of lactase. "Have one crowd really, will suffer from, name disease that lactose does not tolerate by one, it is apt to suffer from diarrhoea that they have drunk the milk, can't absorb the calcium in the milk naturally. " So Professor Zhu proposes, this kind of group, can eat the yoghurt that has already decomposed lactose and melt easily the milk enriches the calcium.
The milk enriches the calcium in this way, is it good to drink benefit more? Beautiful to fit the intersection of locust and arc the intersection of E D and blanket discuss angry to play cook a meal to be high to sift and herd Yan frequently while being striking! The pen settle the male saddle word of tool instrument of gold-plating and drive high Mian's carbuncle sentence to stem Quan of the sixth of the twelve Earthly Branches of Ge and support a fear of Die and warm up Hong Zhyuan's chirp frequently? The milk of 500ml, it is very easy things will develop in the opposite when they become extreme.
Except milk, what methods can enrich the calcium? Professor Zhu proposes:
Vitamin D has the absorption in the human body of calcium " Develop resources and reduce expenditures " Function: On one hand, link the absorption that D can promote a kind of calcium of intestine, meanwhile, when the calcium is discharged in the kidney inside, linking D can promote the renal tubule to absorb calcium again. The content of linking D of the ocean fishes is higher.
Except the milk enriches the calcium to drinking, eat more the intersection of vegetables and fruit, nut, can strengthen human body to to absorb calcium effectively.
Besides the tonic, can also shoulder a heavy task and do exercises appropriately, with the strong skeleton, prevent osteoporosis, keep bone calcium vigor. Certainly, get sun, it is the good method of enriching the calcium too. Staff reporter Zhang MiaoJia
