When buying milk, you don't have to choose expensive ones. Looking for the "three lines" of packaging. Drinking pure milk is healthier.

Recently, we can see from some old photos of the late Qing Dynasty that the height of China people was not low at that time, and even some workers who went abroad were a little taller than westerners, especially Italians and Japanese. You can search these old photos online and have a look. Then why is our average height not as good as that of westerners, and even surpassed by Japan for a time?

I have also read some sayings that the diet structure in the west has changed, the most obvious being the increase of milk and meat. Even Japan later put forward the slogan of "rejuvenating a nation with a glass of milk every day", but because of economic reasons, we still stay in the stage of eating a lot of "carbohydrates" to fill our stomachs, and we can't provide enough protein and calcium. It is conceivable that milk is really helpful to improve our quality and height.

Now there is milk everywhere, meat can be eaten every day, and people's height has been greatly improved. For example, my 177 number was the highest in the school in the 1990s, and I'm afraid it can only be considered as medium in the modern high school classes, so for the next generation, milk must be kept up with high quality. But in the face of "milk" all over the street, are you really giving it to children? Today, I will share the method of selecting high-quality milk, starting from the "three lines" of packaging.

It can be said that the only ingredient that can really be called "milk" should be "raw milk".

Raw milk is pure natural milk squeezed directly from cattle, which has not been processed and sterilized, but raw milk contains many bacteria and microorganisms, and not everyone can digest it. Therefore, for the health of most people, raw milk can only be directly drunk after sterilization. Note that this is only sterilization, and no other additives are added to ensure the purest flavor and nutrition of milk. Only fresh milk at low temperature or pure milk at room temperature can reach this standard.

Some "milk-flavored drinks" add a lot of sugar, pigment and essence to imitate more flavors to satisfy people's appetite, which invisibly increases the metabolic pressure of the human body and makes it easier to be obese. The most important thing is that the nutrients are so low that they can't be absorbed by the human body at all. If these "milk-flavored drinks" are used as milk for the elderly and children, it would be a big mistake.

There is nothing to say. When selecting, avoid some "fake milk" with the word "beverage" on the package, and be sure to pay attention to only one item in the ingredient list: raw milk.

The first task of drinking milk is to bring protein to human body. It is not an exaggeration to call it "white blood", because all important parts of the human body need protein's participation, accounting for about 18% of the human body.

Protein in milk is rich in essential amino acids, which is especially beneficial to human absorption. For example, the "whey protein powder" that fitness enthusiasts often drink comes from the extraction of milk. Simply put, the higher the protein in milk, the better, but too high is unscientific. The general content is between 2.8-3.4%, and some milk with good feeding conditions can reach 4.0. In order to choose better milk, we suggest a minimum of 3.2, so that we can drink 500 a day.

When choosing, you can look at the column of protein in the "Nutrition Composition Table" of the package.

The second task of drinking milk is to supplement calcium. The growth of human bones and the firmness of teeth are inseparable from the participation of calcium. Calcium deficiency is easy to cause rickets in children, developmental retardation in the elderly, osteoporosis and other diseases, and it is an extremely important element in the human body.

Natural calcium can not be absorbed by human body, but can only be absorbed by animals and plants to form active soluble calcium, which is absorbed by human body. For example, this cow eats forage, and whey inorganic salts are formed in milk after digestion and absorption of feed, among which there are many minerals, one of which is "calcium", which is fully absorbed and utilized by the human body after drinking. Of course, it can also be seen that the calcium content has a great relationship with the feeding level. Generally, it should be between 90-100 ml and 20 mg. For health, we suggest that the minimum intake of calcium is 100 mg. Some milk may contain too much calcium, which is probably artificially added, which is not conducive to human absorption. Only the primary calcium of milk is the best.

Like protein, we can observe the column of calcium in the "Nutrition Composition Table", and the best column is 100 mg/100 ml. At the same time, we should pay attention to the "unit" in the composition table to avoid being fooled by some businesses.

Finally, talk about some taboos of drinking milk. First of all, the pure liquid milk we often buy is not suitable for newborn babies. Please note that some of the nutrients are not suitable for the baby's development and growth, and formula milk powder is the best choice. Finally, it is about skim milk. After skimming, the flavor of milk is halved and the taste is slightly worse. Some dieters like to drink it to lose weight, but I want to say that fat is really not a problem. Defatting is accompanied by the loss of nutrients, that's all.
