Intestinal bacteria can show your true age

Intestines absolutely anyone in the world can be called a real home to a huge number of micro-organisms, taking an active part in ensuring the normal vital functions of the human body. So, some bacteria help us in digestion, while the other part helps the function of the immune system and protect us from the invasion of some disease-causing bacteria. Scientists studying the intestinal bacteria, came to the conclusion that the microbes is a peculiar biological clock that can predict the age of the majority of people.

The bacteria that live in the human gut may tell about his age

Intestinal bacteria can talk about the age of their "host"

To learn exactly how to change human gut microbiome over time, the American company InSilico Medicine studied 3,600 samples of intestinal bacteria, obtained from 1165 subjects living around the world.

To conduct an unusual experiment, the team of InSilico Medicine used a special algorithm for deep learning, which has been specifically modeled on a similar to neurons in the brain of the algorithm. The result could surpass all expectations: a unique program has been able to guess the age of the people with an accuracy of approximately 4 years. In addition, it was found that of the 95 species of bacteria that live in the human gut, microbial 39 species were the most important in predicting the estimated age of the subject.

The idea is that you are more likely to correctly predict someone's age based on data from the intestinal microbiome may confuse some people far from scientific knowledge. However, such information may be of great interest to scientists studying the aging process.

Intestinal bacteria can show your true age

A great number of different microorganisms in the intestine contained any living creature. Some of these are and Eubacterium hallii, promoting digestion

The experiment was able to show that some microbes capture large areas of the body as we age. So, Eubacterium hallii, which is considered to be an important participant in the metabolism in the gut, thus becoming perhaps the most common. At the same time, with age significantly reduces the amount of bacteria Bacteroides vulgatus, which often cause inflammation in the human digestive tract and are directly linked to ulcerative colitis. Dieting, sleep and physical activity, is likely to only contribute to such changes.

The study's authors argue that the presence of such "aging clock" human microbiome can be used to check on how fast or slow aging intestines specific person. In addition, the presence of certain bacteria in the gut of the body can have a big impact the use of alcohol, drugs, food supplements or even adherence to a diet. Absolutely all of these factors can affect the length of our lives. If so, scientists hope that the results of the study can be used to determine certain dangerous diseases, including Alzheimer's disease and is. See also: biological aging could be reversed

However, the main problem of this unusual theory of aging of an organism is the fact that despite its universal applicability in determining a person's age, there are huge differences in exactly which bacteria are present in the intestines of people living in different parts of the world. As mentioned above, the number of certain bacteria may influence diet, the presence of certain diseases and, of course, age.

It is unknown whether the changes in the human microbiome affects more rapid aging of people, or such changes are simply a side effect of aging. Be that as it may, the scientists still have something to think about.
