[Health Channel/Comprehensive Report] Family reunions during the Spring Festival often involve a lot of fish and meat for several days in a row, with less fiber and less movement, which can easily lead to constipation. Some people will take probiotics, but is it really effective?
The doctor said that eating probiotics is helpful for defecation, but it should not be taken as an emergency when you are constipated, because probiotics reproduce and metabolize in the intestines, resulting in intestinal pH and secretions, which help prevent the survival of pathogenic bacteria, so Enhance intestinal barrier function and reduce inflammation.
Chen Weiyou, director of Tianxin Colorectal Surgery Clinic, posted on the Facebook fan page "Dean Chen Weiyou of Tianxin Colorectal Surgery", pointing out that the intestine is the largest immune organ in the human body, and its contribution to immunity should not be underestimated. According to research, a high-quality intestine Bacteria can create a perfect immune system, so probiotic supplementation can be said to be a popular health product, and major biotechnology companies are vying to launch probiotic-related health products.
However, it is often found that the public has many myths about probiotics, so he sorted out 4 major myths and solved them at once.
Please read on...
Myth 1. If the name of the strain is correct, it is a probiotic?
The more common probiotics belong to the genus Lactobacillus or Bifidobacterium for bacteria and the genus Saccharomyces for fungi.
However, under biological taxonomy, there are species and even subspecies under the genus name. For example, there are hundreds of species of lactic acid bacteria, but only certain types are helpful to the body, so Probiotics actually need to be scientifically proven, and they can only be called probiotics when it is clinically proven that the use of specific strains is helpful to the body.
Myth 2. It is best to advertise the highest number of bacteria?
For the most common Lactobacillus genus, the most suitable pH value for survival is weak acid. Therefore, when the probiotics enter the stomach, the strong acid will cause a large number of probiotics that are not resistant to acid to die. Therefore, the commercially available probiotic products are roughly divided into: 2 kinds:
1. Human Sea Tactic:
1. Human Sea Tactic:
By ingesting a large number of bacteria, as long as a small number of bacteria can pass through gastric acid and colonize the gastrointestinal tract, they will be beneficial to the body after multiplying.
2. Protection policy:
2. Protection policy:
Through the protection of technological packaging materials, such as crystal balls, capsules, tablets, etc., the probiotics can enter the intestinal tract and then be released.
Myth 3. Probiotics are only helpful for "defecation"?
It is often said that "constipation should take probiotics." It is true that consuming probiotics can help defecation, but it is not used for emergency when constipation occurs.
Because probiotics have a variety of mechanisms that are beneficial to the body or regulate immunity, for example, some lactic acid bacteria can indirectly affect the activation and induction of intestinal immune cells through the Peyer's patch area of the intestinal wall; in addition, the reproductive metabolism of probiotics in the intestinal tract causes intestinal It helps prevent the survival of pathogenic bacteria, thereby enhancing the intestinal barrier function and reducing the occurrence of inflammation.
Myth 4. Dead bacteria are completely ineffective for health care?
If you want to use probiotic supplements to maintain your health, it is of course best to supplement "live" bacteria. After all, live bacteria can maintain a period of time to colonize the intestinal tract, and the induced reactions and effects can last longer. However, dead bacteria do not mean It is completely useless. After the probiotics die, the cells disintegrate and release enzymes, short-chain fatty acids, lipopolysaccharides, metabolites, etc., which are part of the "postbiotics". Postbiotics can create an environment suitable for probiotics and help the body maintain healthy.
