Yogurt and milk differ in taste and nutrients.What is good in yogurt? Yogurt is milk after fermentation. Yogurt is generally called thick, tastes sour; milk is relatively thin, there will be a little bit of astringency after drinking at room temperature, there will be a strong milk fragrance after heating.
Milk is not milk that is not sterilized. Governments around the world have banned the sale of raw milk that has not been effectively sterilized, so, any milk you buy is sterilized.
Fresh milk from cow is also called pasteurized milk. It is a pasteurization method with continuous mild heating. The sterilization temperature is low (63-85 °C), but this temperature is enough to kill all pathogenic bacteria and ensure the safety of milk. It is also because the sterilization temperature of fresh milk is low, so the nutrition of milk can be relatively completely preserved.
Pure milk is treated by instantaneous high-temperature sterilization. The temperature is as high as 135-150°C, and the microorganisms in the milk are all killed. This causes nutrients such as carotene and vitamin E in the milk source to lose about 5% than the fresh milk, and the activity of the protein also decreases. Of course, the biggest benefit of these losses is that the shelf life is doubled. How about Vitamin E benefits? Vitamin E promotes reproduction.
For consumers, if they drink it daily, you naturally drink fresh milk every day. If they need long-term storage or long-distance travel, pure milk is the best nutritional drink.
Yogurt is a kind of milk product that uses fresh milk as raw material, pasteurized and then added beneficial bacteria (fermenting agent) to milk, and then fermented and then cooled.
Compared with pure milk, yogurt is “green out of blue and better than blue”. In the fermentation process, except that most of the lactose of pure milk is converted into lactic acid bacteria, other nutrients are no different from pure milk.
For patients with lactose discomfort, drinking yogurt can avoid the symptoms of diarrhea and abdominal swelling and diarrhea caused by lactose discomfort. That is, yogurt can break down the lactose and protein in milk, making it easier for the body to digest and absorb.
From the nutritional value point of view, there is not much difference between the two, they all contain carbohydrates, protein, fat and calcium, phosphorus and other nutrients, as well as rich vitamin A, vitamin B.
However, to elaborate, yogurt may be more nutritious, because yogurt is fermented based on milk, not only the loss of nutrition, but also the existence of beneficial bacteria, as well as the vitamins produced by the fermentation of beneficial bacteria.
If you simply use pure milk to ferment yogurt, it may be better nutrition, but the yogurt we buy in the supermarket is generally "flavored yogurt", usually added with sweeteners, such as white sugar.
For healthy people, flavored yogurt is only an increase in calories, but for obese people and diabetics, flavored yogurt is not suitable for drinking.
Pure milk can cause diarrhea. Is it better to drink yogurt?
The reason why pure milk causes diarrhea is mainly the effect of lactose, and most people in Asia have lactose intolerance infants. During the fermentation of yogurt, lactose is broken down into lactic acid and organic acids, which reduces lactose intolerance. So yogurt may be less likely to cause diarrhea.
Yogurt does not help digestion?
Some people believe that a cup of yogurt after a meal can help digestion and lose weight. However, yogurt does not have a similar effect. Although it is rich in many beneficial bacteria, these beneficial bacteria cannot enter the intestines and are usually inactivated in the mouth and stomach. Losing weight is even more impossible. Flavored yogurt has higher sugar content and more nutrients, and is not a low-calorie food.
During the fermentation process, only lactose is broken down and other nutrients are still retained. All yogurt still has calcium supplementation.
Many people think that after the yogurt is heated, the beneficial bacteria will be inactivated and lose the health care effect. But the truth is that even without heating, the beneficial bacteria in the yogurt will not reach the intestines. Only after the yogurt is heated, the taste is thinner and the acidity is increased.
A layer of light yellow water appears on the surface of the yogurt that is heated or expires. This is called whey and is not harmful to health. Just a little bit sour.
You can drink yogurt on an empty stomach, depending on the situation. The reason why fasting is not suitable for drinking yogurt is that yogurt is easy to stimulate the increase of gastric acid secretion, which is unfavorable for people with gastric ulcer and hyperacidity.
For lactate intolerance patients, due to the lack of lactase enzyme in the body, as much as possible to choose lactate intolerance products, to avoid the burden of indigestion on the body.
