When it comes to heat, we must understand its composition. Although the brands are different, the contents are mostly milk, oligosaccharides, pectin, fructose and spices. Because China people are generally not used to sour yogurt, so manufacturers will add sugar or fructose to flavor it, which also adds a lot of calories.
Low-fat milk 240C. C contains about 120 calories, while the same amount of low-fat yogurt contains 150-200 calories (depending on the brand), so the calories are more than expected. If you want to drink yogurt with less calories, I suggest you choose yogurt labeled skim and low calories, because the same 240C. C contains only about 100 calories.
Generally speaking, the calories of yogurt are still higher than milk. Female friends who are afraid of obesity should carefully choose brands and types and limit their consumption, otherwise they will unconsciously drink a bunch of calories.
Comparison between yogurt and milk
Yogurt is fermented from pure milk. Lactic acid bacteria can not only retain all the nutrients of fresh milk, but also produce various vitamins necessary for human nutrition during fermentation, such as vitamin B 1, vitamin B2, vitamin B6, vitamin B 12, etc.
Yogurt is also a good source of calcium. Although the nutritional content of yogurt depends on the source and composition of raw milk, generally speaking, the composition of yogurt is higher than that of raw milk, on the one hand, because the quality of raw materials is high, on the other hand, because some yogurt is made with a small amount of milk powder. So generally speaking, drinking a cup of yogurt15og can meet 1/3 of the daily calcium required by children under 0/0 and 1/5 of the calcium required by adults.
Flour fermented into steamed bread is easy to digest and absorb, and milk fermented into yogurt has the same effect. About 20% of sugar and protein in milk are broken down into small molecules, such as galactose and lactic acid, small peptide chains and amino acids.
The fat content in milk is generally 3% ~ 5%. After fermentation, the fatty acids in milk can be increased by 2 times compared with raw milk. These changes make yogurt easier to digest and absorb, and the utilization rate of various nutrients is also improved. Especially for people with lactose indigestion, eating yogurt will not cause abdominal distension, flatulence and diarrhea.
Fresh milk is rich in calcium, and minerals such as calcium will not change after fermentation, but lactic acid produced after fermentation can effectively improve the utilization rate of calcium and phosphorus, so calcium and phosphorus in yogurt are more easily absorbed by human body.
1, it is not good to drink milk on an empty stomach, but it is not impossible to drink milk on an empty stomach.
Because water accounts for a large proportion in milk, drinking more milk on an empty stomach dilutes gastric juice, which is not conducive to the digestion and absorption of food. In addition, on an empty stomach, the intestinal peristalsis is very fast, the speed of milk passing through the gastrointestinal tract is very fast, and the retention time is also very short. Its nutrition is often too late to be absorbed, so it rushes into the large intestine and goes through the motions. Therefore, drinking milk on an empty stomach is not in line with nutrition and hygiene. The ideal breakfast should be protein, a high-calorie meal, and the amount should not be less than a whole day? 0? 4。 Therefore, it is best to drink milk during a nap or before going to bed late, so as to turn disadvantages into advantages and better play its role. If you are used to drinking milk at breakfast, you must also eat some other foods before drinking milk, so that milk can stay in the gastrointestinal tract for a longer time. If you want to drink a bottle of milk for breakfast, you can eat 50 grams of rice or pasta first, then add an egg and a little pickles and dried tofu, and then drink milk, so that milk can be mixed with other foods in the stomach and stay in the gastrointestinal tract for a long time, which is beneficial to the digestion and absorption of its nutrients. Because food provides enough calories, digestion and absorption are slow and sufficient, so that blood sugar keeps at a high level, and you will be full of energy in the morning.
Milk can be heated, but not boiled. Because boiling will destroy some vitamins, calcium in milk will form calcium phosphate precipitation, which will affect the absorption of nutrients by human body. Boiling milk also has some knowledge. Most people will add milk to sugar and cook it with fire. This will make lysine in milk react with sugar at high temperature to produce fructosyl lysine, which will not be digested and absorbed by human body, but will be harmful to human health. So you have to wait until the milk is not hot.
Experts remind citizens not to drink milk on an empty stomach. It is reported that many people drink milk in the morning, thinking that it can completely absorb nutrition. In fact, drinking milk on an empty stomach will soon be discharged into the large intestine through the stomach and small intestine, so that various nutrients will be excreted before digestion and absorption. The correct way should be to eat something before drinking milk. Hyperacidity leads to degeneration and precipitation of protein, and nutrients are not easily absorbed by the stomach, which can lead to indigestion and diarrhea in severe cases. Therefore, some bread, biscuits and snacks should be accompanied by milk. It can be seen that the main reasons for not drinking milk on an empty stomach are: First, it is easy to cause diarrhea; Second, the absorption efficiency is not high. Because the time through the gastrointestinal tract is too fast. Try to drink milk after meals, which is beneficial to absorption and tolerance.
First of all, yogurt is more nutritious than milk.
Yogurt is fermented from pure milk. Lactic acid bacteria can not only retain all the nutrients of fresh milk, but also produce various vitamins necessary for human nutrition during fermentation, such as vitamin B 1, vitamin B2, vitamin B6, vitamin B 12, etc.
Yogurt is also a good source of calcium. Although the nutritional content of yogurt depends on the source and composition of raw milk, generally speaking, the composition of yogurt is higher than that of raw milk, on the one hand, because the quality of raw materials is high, on the other hand, because some yogurt is made with a small amount of milk powder. So generally speaking, drinking a cup of yogurt15og can meet 1/3 of the daily calcium required by children under 0/0 and 1/5 of the calcium required by adults.
Second, yogurt is easier to absorb than milk.
Flour fermented into steamed bread is easy to digest and absorb, and milk fermented into yogurt has the same effect. About 20% of sugar and protein in milk are broken down into small molecules, such as galactose and lactic acid, small peptide chains and amino acids.
The fat content in milk is generally 3% ~ 5%. After fermentation, the fatty acids in milk can be increased by 2 times compared with raw milk.

Fresh milk is rich in calcium, and minerals such as calcium will not change after fermentation, but lactic acid produced after fermentation can effectively improve the utilization rate of calcium and phosphorus, so calcium and phosphorus in yogurt are more easily absorbed by human body.
Health care function of yogurt
Yogurt is not only nutritious, but also contains lactic acid bacteria, so it has health care function. These functions are:
1. Maintain the ecological balance of intestinal flora, form a biological barrier, and inhibit harmful bacteria from invading the intestine.
2. Prevent constipation by producing a large number of short-chain fatty acids to promote intestinal peristalsis and a large number of bacteria to grow and change osmotic pressure.
3. Yogurt contains a variety of enzymes to promote digestion and absorption.
4. By inhibiting the growth of saprophytic bacteria in the intestine and the toxins produced by corruption, the liver and brain can be protected from these toxins and aging can be prevented.
5. By inhibiting the growth of saprophytic bacteria and some bacteria in the intestine. So as to inhibit carcinogens produced by these bacteria and achieve the purpose of preventing cancer.
6. Improve human immune function. Lactic acid bacteria can produce some substances that enhance immune function, which can improve human immunity and prevent diseases.
Yogurt is a long-lived drink.
According to Nobel Prize winner and Russian food expert Mechnikov (1845- 19 16), the earliest research results of yogurt prove that yogurt contains a growth active factor, which can enhance the body's immune function and is beneficial to health, disease resistance and anti-aging. There are many longevity places in the world, and residents have the habit of drinking yogurt for a long time. Some studies believe that Bulgarians live longer because they drink more yogurt, while the average height of Japanese people increases because they often drink yogurt. According to the research results of scholars, the reasons why yogurt is beneficial to human health and longevity may include:
1. Yogurt can enhance human immune function;
2. Reduce serum cholesterol level. Experiments have proved that even without any drugs. Drink about 24 grams of yogurt every meal, and cholesterol can be reduced after one week.
3. Regular consumption of yogurt can promote intestinal movement, shorten the transit time of food from mouth to anus, soften the contents of colon by glycolysis, increase the amount of fecal excretion, prevent constipation, and help prevent colon cancer. So yogurt is called "longevity food" abroad.
