Calcium milk is well known, many dairy products, high calcium milk has become the first choice for many people, but it really has more obvious effect of calcium than ordinary milk it?
Recently, the reporter found in major supermarket surveys that although the price of a pack of high-calcium milk was a few cents more expensive than regular milk, the sales volume was very good. The reporter read the nutrition label of several brands of high-calcium milk and discovered that the calcium content per 100 ml of high-calcium milk is between 125 mg and 130 mg, the highest is 150 mg, and that of ordinary milk is 100 mg. 110 mg.
Fan Zhihong, associate professor of the College of Food Science and Nutritional Engineering at China Agricultural University, told the "Life Times" reporter that according to China's food nutrition labeling regulations, as long as the calcium content per 100 ml of dairy products is higher than 120 mg, calcium can be declared rich, but this quality Better low-fat milk or skim milk can also be achieved. If the product claims to have higher calcium content than the normal product, it must be more than 25% higher than the equivalent product. Surveys show that many products known as high-calcium milk, the calcium content and the gap between ordinary whole milk may not be able to reach more than 25%, compared with ordinary skim milk, there is not so much difference. Therefore, in terms of calcium content, the purchase of ordinary milk has a calcium effect, and "high calcium milk" is not as "unique" as it is.
From the feasibility of adding calcium, Fan Zhihong said that milk itself is already a high-calcium food, in which there is a delicate balance between protein and calcium. Adding a large amount of calcium to milk is actually a technically difficult matter, and it is easy to destroy the stability of the protein system, affecting the taste and bactericidal stability.
In addition, there is no published experimental study on the calcium-added milk products currently on the market, which proves that the additional calcium and milk itself can maintain the same absorption rate of calcium. Therefore, there are products known as high-calcium milk on the market, and it does not mean that drinking ordinary milk can not make calcium. Fan Zhihong believes that the amount of calcium in milk itself is very rich, adults outside the normal diet, drink half a catty of ordinary milk every day, plus green leafy vegetables and tofu, calcium demand can reach the target value.
At present, there are more and more varieties of milk on the market. Apart from high-calcium milk, iron and zinc milk, breakfast milk, fruit and vegetable milk are also common. How to choose the right one for you? Fan Zhihong said that for people who are unable to diversify their diet for various reasons, nutrition fortified milk offers more choices. But for ordinary healthy adults, blindly believe in commercial propaganda. Although everyone's physique is different, there is no unified recommendation, but in general, pure milk is a good choice. Because milk only needs to play the role of milk, it does not have to replace other foods. If you need fruits and vegetables, you can eat fresh fruits and vegetables; if you need breakfast, use milk to eat with the staple food is very good; if you need iron and zinc, eat more seafood, nuts, do not have to look at the little iron and zinc added to the milk.
