Lgg Probiotics, labs Probiotics, B- Dragon Gum, E+ Bacteria, ab Probiotics, ab 100 Probiotic Yogurt ... You may feel dizzy in the face of so many familiar and unfamiliar terms. What is the difference between different strains of probiotic yogurt? What's the impact? Which product has higher nutritional value? Which product should I choose? Our reporter invited relevant experts to answer.
1 Probiotics become fashionable
With a little attention, it is not difficult to find that "probiotics" is a very hot word in the dairy market at present. There are many kinds of probiotic yogurts on the refrigerated shelves of supermarkets, and the words "10 million probiotics" and "××10 million probiotics" often appear in advertisements.
Most of the lactic acid bacteria found at present are beneficial to human health, such as Lactobacillus bulgaricus and Streptococcus thermophilus, which are used to ferment dairy products, but not all lactic acid bacteria are beneficial to human health, and some lactic acid bacteria are harmful to human health, such as Listeria. Probiotics refer to living microorganisms, which can be beneficial to human health when ingested in sufficient quantities. At present, the probiotics mentioned in fermented dairy products on the market generally include Bifidobacterium longum, Bifidobacterium adolescentis, Bifidobacterium animalis, Lactobacillus casei, Lactobacillus acidophilus, Lactobacillus rhamnosus and so on. These probiotics are also lactic acid bacteria, because some of them have strong acid resistance, can withstand the test of human gastric acid, and some can reproduce stably in the human intestine for a period of time, in short, they can provide live probiotics for the human intestine, so they are defined as probiotics.
2 Traditional Yogurt vs Probiotic Yogurt
At present, there are two common yogurt products on the market. One is a traditional yogurt fermented with fresh milk and two kinds of fungi (Streptococcus thermophilus and Lactobacillus bulgaricus). The other is probiotic yogurt with two kinds of lactic acid bacteria (Lactobacillus acidophilus and Bifidobacterium) added on the basis of the former fermentation, and its logo usually has the word "probiotic".
Traditional yogurt does not contain active lactic acid bacteria, but yogurt containing inactive lactic acid bacteria is also very nutritious, because lactic acid bacteria will consume lactose and produce a series of metabolites such as vitamins and enzymes during fermentation, which is beneficial to human body. Probiotic yogurt must contain active lactic acid bacteria, which not only has a series of beneficial metabolites produced during the fermentation of lactic acid bacteria, but also helps to adjust the microecological balance of human intestine.
Generally speaking, when it comes to yogurt fermented by lactic acid bacteria, lactic acid bacteria can be active or inactive; The biggest feature of probiotic yogurt is the word' live'. Probiotic yogurt must be preserved in cold chain from production, production to sales, and a certain number of live bacteria must be maintained during the shelf life, which can be called quality assurance and better improve human health. At present, there is no standard of probiotic active yogurt in China, and the shelf life and storage conditions of probiotic products are not clearly defined. Therefore, consumers must pay attention to the production date when purchasing probiotic yogurt.
3 Understanding Probiotics
Lgg bacteria: lgg was officially named Lactobacillus rhamnosus, which was isolated from healthy people by two American professors from North Carolina State University on 1983 and patented. Lgg strain has the characteristics of strong activity and gastric acid tolerance, and can be colonized in the intestine for up to two weeks.
Labs bacteria: Four kinds of probiotics in Labs probiotic group-L-Lactobacillus bulgaricus, a- Lactobacillus acidophilus, b- Bifidobacterium and s- Streptococcus thermophilus, were developed with full consideration of China people's physical needs and intestinal characteristics and according to China people's taste habits. Its advantages are that it contains Lactobacillus acidophilus and Bifidobacterium, which can colonize and survive in human body and is more beneficial to human health.
E+ bacteria: contains four kinds of lactic acid bacteria: Lactobacillus bulgaricus, Streptococcus thermophilus, Lactobacillus acidophilus and Bifidobacterium. Each gram of active E+ bacteria yogurt contains 654.38+00000 active probiotics.
B-longgum: * * Four lab-beneficial bacteria were used, namely Lactobacillus acidophilus, Bifidobacterium b-longgum, Lactobacillus bulgaricus and Streptococcus thermophilus. Quan Wei yogurt not only has many strains, but also has excellent varieties. Among them, B-longgum is a precious lactic acid bacteria from infants.
Who needs probiotic yogurt most?
Bacteria are the main microorganisms in the human body, with about 400~500 species, hundreds of billions to millions of species in the body, weighing 1.5~2 kg, and most of them are concentrated in the intestine. The microbial flora in the intestine can be roughly divided into beneficial bacteria, harmful bacteria and bacteria of both interest. Microorganisms in the intestine need to maintain microecological balance, but many factors such as aging, disease and antibiotic treatment will cause microecological imbalance in the intestine, which will lead to human diseases.
It is found that artificial supplementation of active beneficial bacteria can not only adjust the imbalance of intestinal microecology, but also make it tend to balance, restore and maintain human health. It can also enhance human immunity; Promote intestinal peristalsis and help digestion; Inhibit the growth of spoilage bacteria; Reduce the risk of rectal cancer and colon cancer; Promote the absorption of minerals, especially calcium; Help lactose intolerant people (people who often feel abdominal distension or diarrhea after drinking milk) digest lactose; Prevent diarrhea caused by virus or salmonella; Prevent allergies and so on.
1. Antibiotic users: When people use antibiotics to treat diseases caused by inflammation, eating yogurt containing active lactic acid bacteria such as Bifidobacterium will help balance the imbalance of intestinal flora, supplement nutrition and avoid toxic and side effects.
2. People who smoke and drink regularly: Yogurt contains a lot of vitamins and some active substances, which helps to reduce the burden of internal organs and reduce the toxicity of tobacco and alcohol to human body.
3. Habitual constipation: Middle-aged and elderly people often eat yogurt, which can stimulate gastrointestinal peristalsis and improve constipation symptoms.
4. Patients with cardiovascular diseases, liver diseases, cancer chemotherapy and other diseases: Regular consumption of yogurt is conducive to the rehabilitation of patients with cardiovascular diseases, liver diseases, cancer chemotherapy and other diseases.
5. Office workers and computer workers: Regular consumption of yogurt contributes to the health of office workers and computer workers.
5 Drinking probiotic yogurt should be scientific.
1. Variety identification: At present, there are many kinds of "milk yogurt" made of milk (milk powder), sugar, lactic acid (citric acid), malic acid, spices and preservatives. Because they do not have the health care function of yogurt, they should be carefully identified when buying.
2. Drink about two hours after meals: the ph value suitable for the growth of lactic acid bacteria is above 5.4, and the ph value of fasting gastric juice is below 2. If you drink yogurt at this time, lactic acid bacteria are easily killed by the high acidity of gastric acid, and the health care function of active bacteria will be weakened. If the gastric juice is diluted after meals, the ph value can be raised to 3~5.
3. Rinse your mouth in time after drinking: With the development of lactic acid bacteria series drinks, the rate of dental caries in children is also increasing, which is the negative effect of some strains in lactic acid bacteria.
4. Do not heat: If the active lactic acid bacteria in yogurt are heated or diluted with boiling water, they will die in large numbers, not only the unique taste disappears, but also the health care value of the active bacteria will be lost.
5. Don't take it with certain drugs: antibiotics such as chloramphenicol and erythromycin, sulfonamides and some drugs for diarrhea can kill or destroy lactic acid bacteria in yogurt.
6. Don't feed your baby yogurt: Yogurt may affect your baby's normal digestive function, especially for infants with gastroenteritis and premature infants.
7. Yogurt should be kept at 2℃ ~ 6℃. Under normal circumstances, active lactic acid bacteria are stored at 0℃ ~ 4℃. At this time, lactic acid bacteria are in a "dormant period", and the bacteria are active, but the reproduction speed is slow; With the increase of environmental temperature, lactic acid bacteria will multiply and die rapidly, and their nutritional value will also decrease. Yogurt containing active lactic acid bacteria has a short shelf life, usually about two weeks, and must be stored at 2℃ ~ 6℃, otherwise it will go bad easily. So when shopping, you must choose the yogurt sold in the refrigerator.
