Researchers confirm that the intestinal flora of people over the age of 100 contains a group of bacteria capable of producing secondary bile acids that protect against some highly resistant pathogens.
The gut microbiome is known to have an effect on skin health, mood and immunity, and has also been shown to be the key to longevity.
In a report published by the magazine “Le Figaro” (the figaro) French, writer Caroline Henry said that Japanese scientists have finally discovered the secret of longevity of aging people after decades of studies.
According to a study conducted at Kino College in Tokyo and published last summer in the scientific journal “Nature”, the intestinal microflora is among the factors that explain the longevity of these people.
These researchers found that the gut flora of people over the age of 100 contains a group of bacteria capable of producing secondary bile acids that protect against some highly resistant pathogens.
These bacteria contribute to maintaining the balance of the intestinal flora.
highly personal data
This new study supports a hypothesis that some researchers have tried for years to prove its validity, including Professor Paul O’Toole, a microbiologist at the University of Cork and a member of the European project “Eldermite”, which is interested in studying the intestinal flora of the elderly.
Scientists hypothesized that the good bacteria living in the gut could determine the speed of aging.
Joel Dory, director of research at a French institute, explains They observed “a change in the intestinal flora in the elderly participants. With age, these microbes lose their richness and diversity due to reduced secretion of protective gut mucus, digestive disturbances, and often due to poor diet quality. This leads to a weakening of the body’s natural defenses and a decrease in the body’s resistance to pathogens.”
The author pointed out that the function of the intestinal microflora is not only limited to facilitating the process of digestion and resistance to pathogens, but also plays a role in regulating immune, metabolic and nervous functions.
According to Joel Dorey, “A disturbance at the level of the intestinal flora would damage the bacterial richness and cause an overgrowth of pathogenic bacteria.”
Over the years, this imbalance leads to a decline in immunity and an increased risk of conditions such as chronic inflammation, cognitive decline, type 2 diabetes, cardiovascular disease, and cancer.
Prebiotics and anti-aging
Can aging be slowed down by enhancing the intestinal flora? Researcher at the Digestive Health Research Institute in Toulouse, Jean Paul Motta, explains “Everyone has their own unique gut flora that develops over time to become unique, and there is no specific microbial composition for everyone for a long, healthy life. We must also take into account the way these microbes interact and their location in the intestine. All this knowledge opens up therapeutic prospects, and requires a better understanding of the functions of the gut flora so that we can tailor them to each individual’s needs.”
Preventive benefits of fasting
Fasting is beneficial for health, whether it is intermittent or sequential. Professor Walter Longo, a specialist in gerontology, says, “Laboratory and clinical studies show that fasting is one of the most effective ways to activate cellular processes such as cell renewal. And rid the body of toxins, as fasting helps to reduce energy consumption effectively without having side effects, and slows down Aging reduces risk factors that increase the likelihood of developing certain diseases.
When practicing intermittent fasting, it is recommended to respect the daily nutritional recommendations such as eating 5 types of fruits and vegetables, 2 servings of vegetable or animal proteins and 3 dairy products.
