Probiotic cultures or probiotics are lactic acid bacteria that support your gut during the digestive process. In particular, the Bifidobacterium and Lactobacillus genera are said to have health-promoting effects. A well-functioning gut is essential for your well-being. On top of that, it strengthens your immune system, as three-quarters of all immune defense cells are located in the intestinal wall. This makes the positive effect of lactic acid bacteria particularly valuable.
Strengthening the immune system with lactic acid bacteria
Various studies have shown that probiotic cultures can positively influence different functions of the human organism. Lactic acid bacteria are capable of stimulating various parameters of the immune system, such as the activity of immune defense cells, the formation of antibodies, and various messenger substances of the immune system. In the large intestine, probiotics create an acidic environment and produce bactericidal substances. This inhibits unwanted germs. Experts are also currently discussing the mechanisms of action of probiotics in connection with the prophylaxis and treatment of vaginal and urinary tract infections in women.
Probiotics for prevention and relief
Scientific studies have also demonstrated positive or preventive effects for certain conditions. These include fewer inflammatory bowel diseases in older people and a reduction in symptoms of atopic dermatitis (eczema). A lower frequency and shorter duration of various diarrheal diseases through probiotic intake is considered scientifically proven. Especially in the case of diarrhea that occurs after antibiotic therapy, as well as traveler's diarrhea, a shortening of the illness by one to two days has been demonstrated.
The secret of Bulgarian farmers
The broad effect of probiotics is nothing new: as early as the beginning of the 20th century, the Russian immunologist Ilya Mechnikov identified the health-promoting effects of lactic acid bacteria from yogurt for the immune system and the fight against germs in the gut. He received the Nobel Prize in Physiology/Medicine in 1908 for this finding. He became aware of it through Bulgarian farmers who reached an above-average age. Their diet included daily lactic acid-containing products such as kefir. The example of the Bulgarian farmers also teaches us: those who rely on probiotics should ensure consistency – because the bacterial strains are nomadic and only colonize the gut for a short time. They must then be replenished through probiotic foods or dietary supplements.
