The salutary effects of foods rich in live lactic acid bacterial cultures have been empirically recognized for millennia, yet it was not until the groundbreaking research of Russian Nobel laureate Élie Metchnikoff in the early 20th century that the scientific community established a formal link between the consumption of fermented dairy products—particularly those containing the *Lactobacillus acidophilus* strain—and the remarkable longevity and robust health observed among rural Bulgarian populations. Contemporary evidence now substantiates that gut dysbiosis, an imbalance in microbial composition, may underlie not only gastrointestinal disturbances such as chronic constipation or recurrent diarrhea but also exert broader systemic effects, including compromised immune function and metabolic dysregulation. This principle was presciently articulated in an ancient Hindu proverb, which underscores the pivotal role of a balanced intestinal microbiota in sustaining physiological equilibrium:
Natural probiotic
Let food be your medicine and medicine be your food.. Hipokrates The food and pharmaceutical market offers a wide range of products containing probiotic strains ranging from fermented milk beverages (yogurt, kefir, butter, acidophilic milk) to sour (sour cabbage.. sour cucumbers) processed plant products (soy products, breakfast cereals, strawberries), dairy substitutes, to pharmaceuticals in the form of tablets, capsules or sazette to dissolve.
Probiotics for weight loss
The composition of gut microflora is an individual trait and is subject to dynamic changes influenced by diet, medicines and other factors.
Probiotics for constipation, diarrhea
As early as the time of Hippocrates, fermented milk beverages, including acidic milk, were attributed therapeutic properties in diseases of the stomach and intestines. Among the most troubling diseases on the digestive tract are diarrhoea, often caused by bacteria, rotaviruses and other viruses (adenoviruses). Numerous studies confirm the validity of the use of probiotics in the prevention and treatment of intestinal disorders.
It's a probiotic for immunity
Most of the research on the effects of probiotics on the body's immunity is concerned with their beneficial effects. It is precisely because of the presence of live cultures of milk fermentation bacteria and the nutrients contained in probiotic products that there is an increase in the natural resistance of the body to various infections. Although the mechanism of action of probiotiks on the human body has not yet been fully explained, using the current state of knowledge, it can be concluded that these friendly bacteria increase the growth of pathogenic microorganisms on the basis of interspecies competition.
Probiotic - side effects
Referring to the old saying that every stick has two ends, it should be emphasized that, despite the abundant evidence of the health benefits of probiotic products, there are also reports of adverse effects of their consumption found in people with immune system disorders. As the literature indicates, probiotics may be closely related to opportunistic microbiology, which can transmit negative genetic traits, and thus cause gastrointestinal disorder in those with significantly decreased food resistance[2].
