We all know that skim milk, but for skim milk is how to skim, I estimate that most people do not know, after all, skimming is just one of the processes, rather than the final result, so there are not a lot of people will go to care about this issue, then skim milk is how to skim it? Let's come together to understand.
Skimmed milk is how to skim1, boiling method
To boil the milk, let it stand for a few hours, remove the top layer of milk skin (ie, fat, this method can generally be removed 80% of the fat) that is. This product is suitable for feeding infants and young children suffering from diarrhea, dysentery, enteritis and other intestinal diseases. Due to the removal of fat milk containing low calorie, lack of vitamin A, D, etc., can be supplemented with other foods, after the disease should continue to feed whole milk.
2, the still method
If you are not in a hurry, in the family will be fresh milk overnight, due to the milk fat contained in the specific gravity of small, so floating in the milk surface, you can use a straw or spoon to remove it.
3, three times boiling method
You can also use boiling to remove the milk skin, three times in a row, so that the fat is reduced to the minimum. However, the method of boiling milk repeatedly is not desirable because many of the nutrients in the milk are destroyed at the same time as the fat is removed.
Contraindications and side effects
Tend to make children fat
Parents always ask their children to drink a lot of milk, the fatter they grow, and skimmed milk is more likely to make children fat than whole milk.
A study of more than 12,000 children aged 9 to 14 showed that children who drank more milk weighed more than those who drank less. But the added calories appeared to be the culprit. However, the findings were surprising: contrary to the hypothesis, dietary calcium and skim milk were associated with weight gain, but milk fat was not.
The Harvard researchers say that teens may be more casual about drinking low-fat milk, so it may not be the milk itself that's causing the weight gain, but the calories in it. An 8-ounce (225-milliliter) serving of whole milk contains 150 kilocalories, and an 8-ounce glass of skim milk contains 85 kilocalories. And the actual message is that children should not drink milk as a way to lose weight or try to control their weight.
The researchers added that the basic drink for children should be water. It is well known that there are many parts of the world where children don't drink milk at all, but they grow up to have healthy bones.
Skimmed milk is when a portion of the normal milk fat is removed, bringing the fat content down to less than 0.5%, which is less than one-seventh of the amount of fat in regular milk, and by skimmed milk, we mean whole skimmed milk.
Skimmed milk has a lot of effects:
One, is the lower pressure. It is generally known that a low-salt, low-fat diet helps blood pressure control, so drinking skimmed milk has a certain auxiliary effect on lowering blood pressure. Hypertensive patients in the choice of milk is best to choose skim milk, which can reduce fat, especially saturated fat intake.
Second, it can prevent cancer. Milk contains vitamin A, vitamin C, calcium and other anticancer effects, while the fat contained therein has a carcinogenic effect, often drink skimmed milk can reduce the risk of oral cavity, colon, bladder, mammary gland, cervical cancer, thus preventing the occurrence of cancer.
It also helps to maintain a healthy weight. Skimmed milk is very good for maintaining a healthy weight, for healthy adults and children and teenagers do not need to choose skimmed products, but for middle-aged and elderly people can consider choosing skimmed milk or low-fat milk. In addition, obese people, diabetic patients are suitable for drinking skimmed milk.
