In everyday life we are constantly surrounded by viruses, bacteria and fungi. But they don't usually make us sick becauseour immune systemsuccessfully combats the pathogens. Especially in Corona times, many people are asking themselves how they can keep their defenses fit so that they can continue to fulfill their tasks optimally. New studies suggest that healthy intestinal flora plays a crucial role.
Scientists have long assumed that the microbiome in our gut stimulates the immune system. But how do they think about it?Intestinal bacteria in balance? A new study addresses this question. A team of researchers from the University Clinic for Visceral Surgery in Switzerland discovered why healthy intestinal flora is so important for our immune system. They found that a small proportion of intestinal bacteria penetrate the blood vessels. The scientists used specially developed computer software to compare the immune response to bacteria in the blood with the immune system's response to bacteria in the intestines.
Using a computer analysis of B cells, the scientists were able to show that the antibodies outside the intestine have a significantly wider range than the antibodies in the intestine. The antibodies in the gut are specialized to fight a limited number of harmful bacteria. The rest of the immune system is more adaptable and has a significantly larger antibody repertoire. So when bacteria enter the bloodstream, they are quickly recognized as harmful and successfully combated. This way blood poisoning can be avoided.
A healthy intestinal flora brings our immune system into constant contact with bacteria and fungi. It is essentially the first “battlefield” and offers the body’s own defenses the opportunity to “train”.
“You are what you eat” – The healthy intestinal flora keeps our immune system in balance
A balanced diet is the first step towards healthy intestinal flora. Nutrition experts recommend consuming at least two handfuls of vegetables and one handful of fruit every day. A healthy menu is still composed of fish, nuts and yoghurt. Smoking can unbalance the intestinal flora, and alcohol is allowed in small quantities. A glass of red wine can even stimulate digestion.
