Various research groups have repeatedly proved that the bacteria living in the human gut can affect the health and cause a number of disorders and diseases such as obesity and depression. According to the latest data, the intestinal bacteria can prevent the development of some kinds of cancer.
A new study conducted in the University of California laboratory, where scientists discovered that certain microorganisms can slow down or completely stop the development of malignant tumors in the body. It is possible that in the future, the analysis of intestinal bacteria will help to reduce the risk of cancer development and, if necessary, a course of probiotics can help to protect humanity against cancer.
A huge number of bacteria lives in the human gut, both useful and not. Each type has its own properties. In the course of investigations, it was found that the bacteria Lactobacillus johnsonii 456, which are among the useful and widely used outside the medical field, are able to positively affect human health. Tests showed that Lactobacillus johnsonii 456 significantly reduces an inflammation in the body and DNA damage. It is worth noting that inflammations play a major role in the development of many diseases – oncology, neurodegenerative, autoimmune diseases, heart disease, and so on are not an exception. The researchers said that by influencing the intestinal microflora, we can significantly slow down the cancer growth process, and probiotics can help to prevent the development of some types of cancer.
To confirm the theory, scientists conducted experiments with rodents who had certain gene mutations that caused Louis-Bar syndrome (a rare inherited disease that affects the skin and nervous system).
The specialists divided all the experimental rodents into two parts – ones of them were obtained bacteria possess anti-inflammatory properties inherent, and the other ones – gut microbes as with anti-inflammatory and so inflammatory properties.
During the observations, scientists have noted that in the rodents, intestines of which had the “good” bacteria, lymphoma (cancer of the immune system cells) developed longer. In the intestine of the rodents treated with a large number of beneficial bacteria (anti-inflammatory) metabolites were detected, which prevents the development of malignant tumors. Also, in this group of rodents improved metabolism have been observed, which also reduces the likelihood of developing cancer.
In addition, the researchers have noted an increase in life span in rodents with “good” microflora, less genetic damage and minor inflammation in the body.
As a result, the researchers noted that taking of probiotics can help to control the composition of the intestinal microflora and can be an excellent preventive measure to prevent the development of malignant tumors.
