Yogurt, generally referred to as yogurt, is a kind of dairy product which takes fresh milk as raw material, adds beneficial bacteria (starter) to milk after pasteurization, cools and fills after alcoholization. At present, most yogurt products on the market are solidified, stirred and fruity with various juices and jams. Yogurt not only retains all the advantages of milk, but also exerts its advantages and avoids its weaknesses in some aspects, making it more suitable for human nutrition and health care products.

Yogurt is more nutritious and easier to digest and absorb than milk.

Flour fermented into steamed bread is easy to digest and absorb, and milk fermented into yogurt has the same effect. During fermentation, 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 improve the utilization rate of various nutrients. 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 vb 1, vb2, vb6, vb 12, etc.

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.

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. Therefore, generally speaking, drinking a cup of yogurt15og can meet13 of the calcium needed by children under 0 and15 of the calcium needed by adults.

Yogurt is a rich source of probiotics.

Probiotics refer to a kind of intestinal physiological bacteria beneficial to human life and health, such as Bifidobacterium, Lactobacillus acidophilus, Lactobacillus casei and other lactic acid bacteria. At present, there are many kinds of yogurt products on the market, including solidified yogurt, stirred yogurt and juice yogurt with different juices, which are sweet and sour and suitable for different tastes. No matter what kind of yogurt it is, it is characterized by containing lactic acid bacteria. These lactic acid bacteria will secrete substances beneficial to human health when they propagate in the human intestine, so yogurt has more benefits to the human body:

First, it can decompose lactose and protein in milk, which is more easily digested and absorbed by the human body;

Second, yogurt can promote the secretion of gastric juice, increase appetite and strengthen digestion;

Third, lactic acid bacteria can reduce the production of some carcinogens, so they have anti-cancer effects;

Fourth, it can inhibit the reproduction of spoilage bacteria in the intestine and weaken the toxins produced by spoilage bacteria in the intestine;

Fifth, it has the function of lowering cholesterol, especially suitable for people with hyperlipidemia.

Sixthly, generally speaking, patients take or inject a lot of antibiotics to treat diseases or prevent infection, which makes the intestinal flora change greatly, and even some beneficial intestinal bacteria are suppressed or killed, resulting in flora imbalance. Yogurt contains a lot of lactic acid bacteria. Drinking 0.25-0.5 kg per day can maintain the normal intestinal flora balance and adjust the beneficial intestinal flora to a normal level. Therefore, people who have recovered from a serious illness drink more yogurt, which has an irreplaceable role in physical recovery. Therefore, it is also what people who have not recovered from a long illness need most.

In general, the content of lactic acid bacteria in yogurt is around 106, which means that the total content of probiotics in yogurt is no less than some similar health foods. Lactic acid bacteria intestinal scavenger can settle in the intestine, which can make beneficial changes in the composition of intestinal flora, promote the secretion of digestive enzymes in the body and intestinal peristalsis, remove intestinal garbage and inhibit the reproduction of spoilage bacteria.

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. Drinking about 24 grams of yogurt per meal can reduce cholesterol 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 abroad.
