Scientists have identified a key to live to be 100 years old, and it’s in the gut.
Infectious agents such as bacteria, viruses, and fungus are fought off by healthy bacteria and immune cells in a healthy gut. According to new research, people who live to reach 100 years old may be able to link their long lives to the presence of specific bacteria in their gut.
There are 300 to 500 different types of bacteria in the stomach, with over two million genes. They form the microbiata, which is unique to each individual when combined with other species. People who survive to be 100 years old are more likely to have bacteria in their stomach that create potent antibiotic chemicals, according to a study published in Nature.
Researchers examined the microbiata of centenarians using feces samples collected from 160 adults over the age of 100.
They compared the microbiata of the centenarians to those of 122 elderly people aged 85 to 89 and 47 people aged 21 to 55.
The researchers discovered that odirobacteriaceae, a bacteria that inhibits the growth of other harmful bacteria by creating specific bile acids, was prevalent in the guts of people over the age of 100.
Researchers discovered that, when compared to aged and young people, centenarians had a higher concentration of gut microorganisms capable of producing the unique bile acid.

Bile is a fluid produced by the liver and retained in the gallbladder, according to the National Institutes of Health.
Bile acids are bile acids that help with digestion.
Bile acids are produced in the liver and then released into the intestine, where they undergo chemical modification to become secondary bile acids.
Professor Kenya Honda of Keio University of Medicine in Tokyo, the study’s lead author, told the Daily Mail: “Perhaps genetic factors and food have an impact on the composition of the gut microbiota.”
“These bugs could be inherited, but we don’t have any evidence that this is the case.”
Isoallo-lithocholic acid, a bile acid, has previously been shown to have a powerful antibacterial impact against a variety of gut pathogens.
The acid was notably effective in fighting the drug-resistant disease Clostridioides difficile, a bacteria that causes severe diarrhoea, particularly in those taking antibiotics.
C. difficile infections, according to the NHS, can sometimes result in significant intestinal problems.
The “Brinkwire Summary News” was also discovered by the researchers.
