Kefir effect at night on intestinal microflora: Deep examination
Section 1: The basics of intestinal microflora and its value
The intestinal microflora, also known as the intestinal microbia, is a complex and dynamic ecosystem of microorganisms that inhabit the gastrointestinal tract (gastrointestinal tract). This population includes trillions of bacteria, archaea, fungi, viruses and other microbes that coexist in symbiotic, commentary or, in some cases, pathogenic relationships. The composition and function of the intestinal microbioma are unique to each person and are affected by many factors, including genetics, diet, age, geographical location, taking drugs (especially antibiotics) and lifestyle.
1.1. The composition of the intestinal microflora:
The dominant bacterial filles in the human intestines include firmicutes, bacteroidetes, Actinobacteria, Proteobacteria and Verrucomicrobia. Within these fils, there is a huge variety of species and strains, each of which has unique metabolic abilities and functions. For example, Firmicutes, as a rule, prevail in the intestines and participate in the breakdown of complex carbohydrates and energy production. Bacteroidetes, on the other hand, play an important role in the degradation of dietary fibers and the production of short -stinging fatty acids (KCHK). Actinobacteria, especially bifidobacteria, is often associated with intestinal health and immunomodulating effects. Proteobacteria, although present in smaller quantities in healthy people, can multiply in conditions of dysbiosis and associate with inflammatory diseases.
1.2. Functions of intestinal microflora:
The intestinal microflora performs many important functions necessary for the health and well -being of a person. These functions include:
- Enough of food: Microbes in the intestines help to digest complex carbohydrates, fibers and other substances that the human body cannot digest independently. They produce enzymes that break down these substances into smaller molecules, which can then be absorbed by the body.
- Vitamin synthesis: Some bacteria in the intestine synthesize important vitamins, such as vitamin K, group B vitamins (for example, biotin, folic acid) and some amino acids.
- Metabolism of drugs: Intestinal microflora can metabolize drugs, affecting their effectiveness and toxicity. Some bacteria can inactivate medicines, while others can turn them into active forms.
- Pathogenic protection: The intestinal microflora competes with pathogenic microorganisms for nutrients and space, preventing their reproduction and colonization. Some bacteria also produce antimicrobials that kill or suppress the growth of pathogens.
- Development and modulation of the immune system: Intestinal microflora plays an important role in the development and functioning of the immune system. It helps to teach immune cells to recognize and respond to pathogens, and also helps to develop tolerance to harmless substances, such as food antigens.
- Production of short -chain fatty acids (KCHK): The bacteria in the intestines are fermented by dietary fiber, producing KCHK, such as acetate, propionate and butyrate. KCHK is the main source of energy for the cells of the colon (colonocytes) and have a wide range of useful effects, including anti -inflammatory and immunomodulating properties. Butyrate, in particular, plays an important role in maintaining the integrity of the intestinal barrier and preventing a “holey intestine”.
- Influence on mood and behavior: Growing data indicate that intestinal microflora can affect the mood and behavior through the axis of the “intestines-mozg”. Bacteria in the intestine can produce neurotransmitters, such as serotonin and dopamine, which affect the mood, as well as modulate the activity of the immune system and nervous system, having an indirect effect on the brain.
1.3. Dysbiosis of intestinal microflora:
Dysbiosis is a violation of the balance of intestinal microflora, characterized by a decrease in diversity, a change in the ratio of various types of bacteria and an increase in the number of pathogenic microorganisms. Dysbiosis can be caused by many factors, including a diet, taking antibiotics, stress, infections and chronic diseases.
Dysbiosis is associated with a wide range of diseases, including:
- Inflammatory diseases of the intestine (BCC): Ulcerative colitis and Crohn’s disease.
- Irritable bowel syndrome (SRK).
- Autoimmune diseases: Rheumatoid arthritis, multiple sclerosis, type 1 diabetes.
- Obesity and metabolic syndrome.
- Allergies and asthma.
- Depression and anxiety.
- Autism.
Maintaining healthy intestinal microflora is crucial for general health and well -being.
Section 2: kefir: composition, properties and mechanism of action
Kefir is a fermented milk drink obtained by adding kefir grains to milk. Kefir grains are complex symbiotic communities of bacteria and yeast enclosed in a matrix of polysaccharides and proteins. Unlike yogurt, which usually contains only a few types of bacteria, kefir contains a much wider range of microorganisms, which gives it unique properties and potential health benefits.
2.1. Kefir composition:
Kefir contains a wide range of nutrients and biologically active compounds, including:
- Probiotics: Kefir contains many probiotic bacteria, such as Lactobacillus, Bifidobacterium, Streptococcus, Leuconostoc And Acetobacter. The specific composition of probiotic bacteria varies depending on kefir grains and fermentation conditions.
- Yeast: Kefir also contains yeast, such as Saccharomyces, Kluyveromyces And Torlespora. Yeast in kefir can contribute to the taste, texture and nutritional value of the drink.
- Lactic acid: Lactic acid is the main product of kefir. It gives kefir a characteristic sour taste and has canned properties.
- Acetic acid: Acetic acid is also present in kefir in small quantities. It gives kefir a tart taste and can have an antimicrobial effect.
- Carboneless gas: In the process of fermentation, carbon dioxide forms, which gives kefir a slightly sparkling texture.
- Amino acids: Kefir contains all essential amino acids necessary for human health.
- Vitamins: Kefir contains B vitamins, vitamin K and vitamin D (if milk used to prepare kefir was enriched with vitamin D).
- Minerals: Kefir contains calcium, magnesium, phosphorus and potassium.
- Kefiran: Kefiran is a unique polysaccharide produced by kefir grains. It has immunomodulating, antioxidant and antitumor properties.
- Peptides: In the process of fermentation, milk proteins are split into peptides, which can have biological activity, such as antioxidant, antihypertensive and immunomodulating activity.
2.2. The beneficial properties of kefir:
Thanks to its rich composition, kefir has a number of healthy health properties, including:
- Improving intestinal health: Probiotics in kefir can help restore the balance of intestinal microflora, suppress the growth of pathogenic bacteria and improve digestion.
- Strengthening the immune system: Probiotics and kefiran in kefir can stimulate the immune system, increase resistance to infections and reduce the risk of allergic reactions.

2.3. The mechanism of kefir action on the intestinal microflora:
Kefir affects the intestinal microflora through several mechanisms:
- Direct addition of probiotics: Kefir brings living probiotic bacteria and yeast to the intestines. These microorganisms can colonize the intestines and multiply, increasing the variety and number of beneficial bacteria.
- Competition with pathogens: Probiotics in kefir compete with pathogenic bacteria for nutrients and space, preventing their reproduction and colonization.
- Production of antimicrobials: Some probiotics in kefir produce antimicrobials, such as lactic acid, acetic acid and bacteriocin, which kill or suppress the growth of pathogenic bacteria.
- Improving the barrier function of the intestine: Kefir can help strengthen the barrier function of the intestine, preventing the “holey intestine” and reducing the risk of inflammation. Probiotics in kefir can stimulate the production of mucus, which protects the intestinal mucosa, and strengthen dense contacts between the intestinal cells.
- Modulation of the immune system: Kefir can modulate the immune system, reducing inflammation and increasing resistance to infections. Probiotics in kefir can stimulate the production of immune cells and cytokines, which regulate the immune response.
- Production of short -chain fatty acids (KCHK): Probiotics in kefir can ferment dietary fiber, producing KCHK, which have a wide range of useful effects on the health of the intestines and the whole organism.
Section 3: Kefir at night: concept and potential advantages
The concept of using kefir at night is based on the assumption that this time of day can be optimal for the effects of probiotics on the intestinal microflora. During the night, when the digestive system slows down, probiotics can have more time to colonize the intestines and have its beneficial effects.
3.1. Justification of the use of kefir at night:
- Slow digestion: At night, digestion slows down, which means that probiotics in kefir can remain in the intestines longer and interact with the microflora.
- Less competition with food: The use of kefir on an empty stomach, for example, before going to bed, reduces competition with other food substances for adhesion to the intestinal mucosa.
- Intestinal recovery: Night is the time when the body is restored and regenerated. The use of kefir at night can help support the restoration of the intestine and improve its functioning.
- Improvement: Some studies have shown that probiotics can improve sleep. The use of kefir at night can contribute to a calmer and more deep sleep.
3.2. Potential benefits of using kefir at night:
- Improving digestion: Kefir at night can help reduce bloating, gases and constipation, improving overall digestion.
- Strengthening the immune system: Kefir at night can help strengthen the immune system, reducing the risk of infections and allergic reactions.

- Improvement: Kefir at night can contribute to a calmer and more deep sleep, improving overall well -being.
- Weight control: Some studies have shown that probiotics can help in weight control. Kefir at night can contribute to weight loss or maintaining a healthy weight.
3.3. Scientific data on the use of kefir at night:
Despite the fact that the concept of kefir at night is attractive, scientific data confirming its advantages is not yet enough. Most studies devoted to the effects of kefir on the intestinal microflora did not specifically consider the time of day of use. However, the results of these studies as a whole confirm the beneficial effect of kefir on the health of the intestines and the whole organism.
Additional studies are needed to determine the optimal time of day to use kefir and study the specific advantages of using kefir at night.
Section 4: KEFIRA effect on specific groups of bacteria in the intestines
