Do you want to buy yoghurt according to the strain

I found that today's yoghurt packaging terms are various, "probiotics", "Lactobacillus", "Bifidobacterium" There are no less than 10 names What are all kinds of "bacteria"? What's the difference? What benefits does eating have to the body? Hu Changli, Ph.D., Key Laboratory of functional dairy products, China Agricultural University, said: according to the different strains, yoghurt can be divided into two categories: one is ordinary yoghurt, which only contains two kinds of legal Lactobacillus (Lactobacillus bulgaricus and Streptococcus thermophilus); the other is probiotic yoghurt, which contains other lactobacillus, such as Lactobacillus acidophilus and Bifidobacterium, in addition to the above strains The price of yogurt is often on the high side Lactobacillus bulgaricus and Streptococcus thermophilus are "transient" health-care bacteria, that is to say, most of these bacteria will not enter the large intestine and can not play the role of "adjusting the intestinal flora" The Lactobacillus acidophilus, Bifidobacterium, some strains of Lactobacillus casei, and some other strains such as Lactobacillus rhamnosus were added to the probiotic yoghurt After long-term screening and scientific research, it has been proved that their health care effect is relatively strong, such as Bifidobacterium can produce lactic acid and acetic acid after fermentation in human intestine, which can promote the absorption of iron and vitamin D; Lactobacillus acidophilus can help In the process of protein digestion, lactic acid, antibiotics and B vitamins are also produced Therefore, theoretically, this kind of yoghurt may be beneficial to regulate the balance of intestinal microorganisms However, the benefits of probiotic yoghurt to the body are still not evaluated And probiotics must reach a sufficient number of viable bacteria, in order to play a sufficient role in health care According to the research report, the number of probiotics should reach 106 or even 108 to have enough health care activity Now, not all probiotic yoghurt will indicate the number of probiotics in it, which consumers should pay special attention to when choosing It should be noted that although ordinary yoghurt has no special probiotics, its nutritional value can not be ignored If you just want to get protein, calcium and multi vitamins to promote digestion and absorption, you can buy ordinary yoghurt directly.
