With the improvement of people's living standards, milk as a nutritional, inexpensive drink has been loved by most people.
If it weren't for someone who was lactose intolerant and diluted as soon as they drank milk, milk could almost be said to be perfect.
However, being close to perfection means that there are still defects, such as the fat in milk.
When it comes to fat, everyone may subconsciously think of it - fat.
The so-called white covers a hundred ugliness, a fat destroys everything. It's easy to get fat, it's hard to lose weight.
Therefore, merchants who are good at satisfying consumers have launched "skim milk", a milk variety that adds "weight loss power".
"Healthier" skim milk is a little more expensive than low-fat milk
But the question is, is it really better to lose skim milk that loses the fat burden?
<h1 class="pgc-h-arrow-right" data-track="10" > some consumers have raised three questions:</h1>
The reason for the birth of skim milk is not to give low-fat demanders, skim milk is just to refine fat when making butter and other items, and the remaining by-products, to make a concept to sell to consumers, is to clean up garbage.
Skimmed milk and whole milk only 6%-3% fat difference, 330ML per day for example, there is no difference at all, you eat a fingernail of meat, fat intake is more than this.
The most critical statement is that the nutrients in milk are fat-soluble, and the fat is removed, and these nutrients are also lost in large quantities.
<h1 class="pgc-h-arrow-right" data-track="16" > allows me to answer the above questions one by one. </h1>
First, the misunderstanding: in the end is there skimmed milk first, or full milk?
Presumably, there are many people like me who subconsciously believe that skim milk is processed from whole milk.
And the reality is that there is no skimmed milk, and then there is full milk, as well as milk with various fat ratios.
In the modern milk processing process, raw milk has to go through the step of defatting (the fat is processed after defatting, so that the fat is more stable and not easy to separate from the milk), and the whole milk and low-fat milk are only all or partially added back to the extracted and processed fat. The fat removed from skim milk is processed into other dairy products, so skimmed milk is generally cheaper than full and low fat milk.
I don't know, have you noticed the focus of this introduction on appeal?
Therefore, compared to full-fat and low-fat milk, skim milk is cheaper.
As for, why is it that the price is a little more expensive without a process?
This may be the manufacturer added something else, after all, the taste of skim milk is really not flattering.
On the answer to the first question, skim milk is not called garbage.
Second, how many calories are missing from skim milk.
Let's look at the diagram first. (Different milk brands, the data may be different)
It can be seen that for every 100ml, the fat of the two types of milk differs by 4g, while the calorie difference is almost doubled.
Let's compare it with the common staple food, rice.
The calories of 100 g of rice are equal to 117 kcal and equal to 491 kJ.
So, the calories of 100ml of whole milk are about equal to 100ml of skim milk + 30g of rice.
A carton of milk 250ml, whole milk is equal to eating 76g more rice, a bowl of rice about 100g, equal to half a bowl of rice. If a person drinks 2 drinks milk a day, he does consume a lot of calories.
If you feel that the rice is mixed with water and is not intuitive, then take a look at the meat.
According to lean meat calculations, 100g of lean meat calories 143 kcal, equal to 600 kJ.
A box of 250ml of whole milk has 62g more lean pork than skim milk.
62g, in the eyes of different people also have different weights.
People who don't care don't care, and for people who are very picky about weight, eating 62g more meat is not a small sin.
Third, how much less nutrients is missing from skim milk?
The nutrients in milk, aside from the most important proteins, can be divided into two categories: water-soluble and fat-soluble.
Water-soluble nutrition, such as water-soluble vitamins, calcium and other content, there is little difference between the two types of milk.
Fat-soluble nutrition, without the solvent of fat, the content in skim milk is almost nothing.
The key question, then, is how valuable these lost nutrients are.
Vitamin A: Essential vitamins necessary for growth and development, cell recognition, vision (lack of which causes night blindness), immune function, and reproduction. It is a powerful antioxidant and acts as a hormone in the body, affecting the expression of genes and thus affecting phenotype. It also helps the heart, lungs, kidneys, and other organs function properly.
Vitamin D: Improves brain flexibility and enhances memory; promotes calcium absorption, promotes bone growth (milk drinking children grow taller); regulates immune function.
Vitamin E: Belongs to antioxidants, delays aging, improves cell vitality, improves body immunity, and effectively improves sleep quality.
In this way, the nutritional value of skim milk is indeed much less than that of whole milk.
But here's a reminder. Although the nutrition of whole milk is comprehensive, it cannot be drunk with an open stomach in order to increase nutrition, otherwise it will be more than worth the loss if you drink it into a fat person.
Fourth, does fat have no other role than fat?
Finally, let's talk about fat.
In the six major nutrients needed by the human body, protein, lipids, carbohydrates, vitamins, inorganic salts (minerals) and water, fat also has its own place, so it cannot be completely rejected.
After all, fat also has a unique physiological effect.
One of the biggest roles is that -
delicious.
Think of smooth cream, think of roast meat dripping with oil, think of fried potato chips...
Honestly, not really
Drooling?
The skim milk that loses the fat not only does not have a rich milk aroma, but also has a large difference in taste.
Someone made a figurative analogy: if whole milk is a dish, skimmed milk is the water that brushes the pot.
After talking about the taste, let's talk about seriousness.
There are many useful masters in fat.
Conjugated linoleic acid is said to have a miraculous effect of reducing fat, but the content of ordinary milk is not very high. Some say that only yak milk is found, and some say that only naturally grazing cattle have it.
In my opinion, the lazy way to lose weight by eating is always not very reliable, and there is no need to pursue too much.
