From the point of view of nutrition, the nutritional value of milk: fresh milk is gold, yogurt is silver, milk powder is copper, and normal temperature milk is iron. Milk drinks have no nutrition at all.
What are "fresh milk" and "normal temperature milk"? There are basically two kinds of sterilization methods.
One is pasteurized milk, which is our common "pasteurized milk" (that is, the milk you ordered). As the name implies, it is pasteurized milk. The so-called "pasteurization" is to kill pathogenic bacteria in milk for a long time at low temperature and keep bacteria beneficial to human body. Because this method can not eliminate all microorganisms in milk, the product needs to be refrigerated, and the shelf life is short, usually only a few days.
The other is called sterilized milk (also called normal temperature milk), which uses high temperature to kill all bacteria in milk. Because there are no microorganisms in milk, the nutrition of milk is seriously destroyed. This milk has no active substance at all. Strong heating will denature protein, and most vitamins will be lost, which will also change the taste of milk.
Stored at room temperature, and the shelf life is relatively long, generally up to more than 30 days.
As a magic weapon to improve the physical quality of the nation, milk has existed in many countries and nations. When talking about the reconstruction of Europe after World War II, former British Prime Minister Churchill once said: "Nothing is more important than providing milk to children!" . After World War II, the Japanese even put forward the slogan "A glass of milk makes a nation strong", which significantly improved the physical quality of the post-war generation. Historically, American residents have also solved the problem of calcium nutrition through the "three cups of milk" campaign. Dairy products have become the main food for westerners.
Now it is undeniable that the average height of Japanese young people has surpassed that of China, and I have no particularly effective way to publicize the second question.
There are many benefits for girls to drink milk. You can read my blog, which contains hundreds of articles about drinking milk.
