How much can yoghurt be used to nourish bacteria

In recent years, some yoghurt has been claimed to have added more than one billion probiotics, which has the functions of detoxification, beauty, bowel, weight loss, immunity enhancement, and even anti-aging What is probiotic? Is probiotic yoghurt so magical? In the past golden week of the national day, have you ever eaten the milk until your stomach swells? At this time, do you think that the advertisement often says that a certain yogurt contains probiotics, which is an expert in intestinal health, and you are willing to pour hundreds of ml of yogurt to promote gastrointestinal peristalsis and speed up food digestion? In recent years, various kinds of probiotic food and health care products are emerging in the market, the most common one is yoghurt Some yoghurt that claims to add more than one billion probiotics will claim that it has the functions of detoxification, beauty, bowel, weight loss, immunity enhancement, and even anti-aging So, what are probiotics? Is probiotic yogurt really so magical? It can enhance intestinal resistance and prevent diarrhea caused by flora disorders More than 100 years ago, Russian immunologist megonikov noticed that Bulgarian farmers are healthier and live longer He attributed it to the living bacteria in the fermented milk they ate, and the concept of probiotics came into being The so-called probiotics do not refer to a particular kind of bacteria, but a general term for living microorganisms that play a beneficial role in the host by improving the intestinal flora balance of the host There are three kinds of bacteria in the intestines of healthy people: beneficial bacteria (probiotics), harmful bacteria and conditional pathogens These bacteria exist in a certain proportion, inhibit the excessive reproduction of pathogens through various ways, and adjust the defense mechanism of human body to resist the invasion of pathogens "Probiotics have a positive effect on maintaining the balance of flora and preventing diarrhea caused by flora imbalance." Dr Yang Xiaoqiang, a gastroenterologist at Guangzhou General Hospital of Guangzhou Military Region, who specializes in microbiological research, believes that from the perspective of prevention of intestinal diseases, proper supplementation of probiotics can indeed resist the occurrence of these diseases and enhance intestinal resistance But he also stressed that probiotics should be selected according to the number of active strains and intestinal design of different ages, because the number of probiotics needed for different ages is different Some experts in the industry think that with the growth of age, the number of probiotics in the intestines of middle-aged and old people is less, and drinking some probiotic yoghurt just can make up for the shortage And children should not drink too much, because they are in development, do not need too much "external force" If you drink too much, it will have a bad effect on your delicate stomach In addition, Yang Xiaoqiang also pointed out that probiotics only change the intestinal microecology, and no research has shown that probiotics can affect the immune system and enhance immunity Only "live" probiotics can survive how many can enter the large intestine alive It is not known that yogurt is fermented by milk Generally, yoghurt is fermented by two specific Lactobacillus strains: Lactobacillus bulgaricus and Streptococcus thermophilus And these two kinds of bacteria are usually regarded as probiotics Dr Yun inadvertently pointed out that although in the marketing of yoghurt, businesses usually give probiotics a lot of color, but in fact, it is not necessary to take it as a reason to eat yoghurt, because the role of probiotics is mainly dependent on "speculation", and the real clinical evidence is not so rich Wang dingmian, a Chinese dairy expert, stressed that yoghurt or lactobacillus beverage containing probiotics has the main health care function of "living" probiotics It is undeniable that yoghurt is often with a large number of live bacteria when it is just produced, but after a series of processes such as packaging, delivery, transportation, shelf, sales, etc., the active probiotics contained in yoghurt will die due to the change of storage temperature Therefore, it is not known how many of these active bacteria can survive into the large intestine and settle down after drinking Moreover, probiotics are not useful only by eating one or two According to the research report, only when the number reaches 107 or even 108, can it play a sufficient health care role Fan Zhihong, associate professor of the school of food safety and nutrition science, China Agricultural University, pointed out that, since there are no corresponding laws and regulations in China to make rigid requirements for the live bacteria content of any probiotic in yoghurt products, nor a complete set of system for monitoring Although some yoghurt brand packages are marked with "high-tech probiotics", whether or not they have been added or not How many, is the manufacturer to say, even appeared in the probiotic fermentation dairy products can not test the probiotic phenomenon Probiotics do not abuse or lead to dependence or breeding of superbugs In theory, probiotics have no side effects on human health, and proper supplementation can improve the intestinal environment However, fan Zhihong pointed out that it is not omnipotent, neither health care drugs, nor tonics, blind abuse may even have a negative impact on health Generally speaking, probiotic oral preparation is only used in the clinical treatment of patients with intestinal failure or disorders Although oral probiotic products can obtain beneficial bacteria in the human intestinal tract in a short time, long-term use will pose potential harm to the human body Because the long-term use of synthetic probiotic products by human body will cause the intestinal function to gradually lose its ability to reproduce beneficial bacteria, and the long-term human intestinal will produce dependence, which is called "probiotic dependence" in medicine Once suffering from "probiotic dependence", people will rely on and use synthetic oral probiotic products for life to maintain their health In addition, some medical experts also put forward that overuse of probiotics may become a new hotbed for breeding "superbugs" Because many lactic acid bacteria have multiple resistance to antibiotics, through living and contacting with pathogenic bacteria, it is possible to transfer the resistance gene carried by them to pathogenic bacteria, so that they can obtain resistance and become "super bacteria", which may lead to no medicine when they are infected Other possible side effects include the effects of carbohydrate and fat metabolism and immune dysfunction Therefore, both nutrition experts and medical experts agree that if you have a reasonable diet structure, you can get the nutrition you need from the normal diet, and have a good lifestyle, then you do not need to add probiotics If you really need to supplement probiotics, you should also take them under the guidance of a doctor or nutritionist Never abuse them blindly to avoid endless troubles.
