Drink yogurt to help probiotics, how much can be used

In recent years, some yogurt claims to add more than one billion probiotics, which have the effects of detoxification, beauty, intestinal, weight loss, immunity enhancement, and even inhibition of body aging. What is probiotics? Is probiotic yogurt really amazing?

In the past National Day Golden Week, have you ever eaten the sea cucumber to the belly of the rising? At this time, will you think that a certain yogurt contains an intestine health expert, probiotics, and you will give up hundreds of milliliters of yogurt to promote gastrointestinal motility and accelerate food digestion?

In recent years, various kinds of foods and health supplements that supplement probiotics have emerged in the market. The most common ones are yogurt. Some yoghurts that have added more than one billion probiotics will claim to have detoxification, beauty, bowel, weight loss, Enhance immunity, and even inhibit the body's aging. So, what about probiotics? Is probiotic yogurt really amazing?

Can indeed enhance intestinal resistance

Prevents diarrhea caused by dysbacteriosis

More than 100 years ago, Russian immunologist Megonikov noted that Bulgarian farmers are healthier and longevity. He attributed the reason to the living bacteria contained in the fermented milk they consumed, and the concept of probiotics was born.

The so-called probiotics are not specific to a certain kind of bacteria, but are a general term for living microorganisms that exert a beneficial effect on the host by improving the balance of the intestinal flora 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 over-reproduction of pathogenic bacteria through various ways, and adjust the body's defense mechanism to fight against Invading pathogens. "Probiotics have a positive effect on maintaining the balance of the flora and preventing diarrhea caused by dysbacteriosis." Dr. Yang Xiaoqiang, a digestive physician at the Guangzhou General Hospital of the Guangzhou Military Region who specializes in microbiology, believes that from the perspective of preventing intestinal diseases, Supplementation of probiotics can indeed prevent the occurrence of this disease and enhance intestinal resistance. At the same time, he also stressed that probiotics need to be selected according to the number of active strains and gut design of different ages, because the number of probiotics required by different age groups is different.

Some experts in the industry believe that with the increase of age, the beneficial bacteria in the intestines of middle-aged and elderly people become less, and drinking probiotic yoghurt can just make up for the deficiency. Children should not drink too much because they are developing and do not need too much "external force." If you drink too much, it will have an adverse effect on its delicate stomach.

In addition, Yang Xiaoqiang also pointed out that the supplement of probiotics changes only the intestinal micro-ecology, and no studies have shown that probiotics can affect the human immune system and enhance immunity.

Probiotics are only "living" to probiotics

How much can live alive into the large intestine is still unknown

Yogurt is obtained by fermentation of milk. Generally, yoghurt is fermented by two specific lactic acid bacteria: Lactobacillus bulgaricus and Streptococcus thermophilus. These two bacteria are also often used as probiotics. Dr. Yun, a doctor of biology and food engineering at Purdue University, pointed out that although in the marketing of yogurt, merchants usually give probiotics a lot of color, but in fact, there is no need to use it as a reason to eat yogurt, because the probiotics in the end can How much it plays, mainly relying on "speculation", the real clinical evidence is not so rich.

Chinese dairy expert Wang Dingmian stressed that yogurt or lactic acid bacteria beverages containing probiotics are mainly “live” probiotics. It is undeniable that yogurt has a large number of live bacteria when it is just produced. However, after a series of processes such as packaging, delivery, transportation, racking, and sales, the active probiotics contained in the yogurt will die due to changes in storage temperature. . Therefore, it is not known how many of these active bacteria survive to enter the large intestine and settle down after drinking. Moreover, probiotics are not useful for eating one or two. From the research report, only when the number reaches 107 or even 108, can it play a sufficient health care role.

Fan Zhihong, an associate professor at the College of Food Safety and Nutrition Sciences of China Agricultural University, pointed out that in view of the fact that there is no corresponding regulation in China to make a hard requirement for the viable bacterial content of any probiotic in yogurt products, there is no complete system for monitoring, some Although the yogurt brand packaging is marked with “high-tech probiotics”, whether or not there is any addition or addition is the manufacturer’s self-talk, and even the phenomenon that probiotics cannot be detected in probiotic fermented dairy products.

Probiotics are not much better

Abuse or cause dependence or gestation of super bacteria

Although in theory, probiotics have no side effects on human health, proper supplementation can improve the intestinal environment. However, Fan Zhihong pointed out that it is not a panacea. It is neither a health care drug nor a tonic. Blind abuse may even have a negative impact on health.

In general, probiotic oral preparations are limited to patients who are clinically used to treat intestinal failure or disorders. Although oral probiotic products can obtain beneficial bacteria in the human intestinal tract in a short period of time, long-term use will constitute the human body. Potential hazards. Because the human body uses synthetic probiotic products for a long time, it will promote the intestinal function to gradually lose its ability to reproduce beneficial bacteria. The human intestinal tract will have dependence for a long time, which is medically called "probiotic dependency." Once suffering from "probiotic dependency", people will rely on and use synthetic oral probiotic products for life to maintain their health.

In addition, some medical experts have also pointed out that the excessive use of probiotics may become a new breeding ground for "superbugs". Because many lactic acid bacteria have multiple resistance to antibiotics, through the common life and contact with pathogenic bacteria, it is very likely that the drug resistance genes carried by them will be transmitted to the pathogens, making them resistant to drugs and becoming "superbugs", resulting in no infection. The medicine can be treated. Other possible side effects include affecting the metabolic functions of carbohydrates and fats, as well as immune dysfunction.

Therefore, both nutrition experts and medical experts agree that if your diet is well structured to get the nutrients you need from a normal diet, and you have a good lifestyle, you don't have to add probiotics. If you really need to supplement probiotics, you should also take it under the guidance of a doctor or dietitian. Do not blindly abuse it to avoid endless troubles. (Technology Daily)
