There are many types of probiotics with different functions. Common probiotics can be roughly divided into Lactobacillus, Bifidobacterium, Bacillus and Clostridium. For example, some probiotics are acid-resistant and can pass the test of gastric acid. Some are acid intolerant and have difficulty reaching the gut to colonize. The function of each probiotic is very different. It is best to first understand the growth conditions and functions of various probiotics, which is of great help in purchasing probiotic products.
Lactobacillus
Lactobacillus acidophilus: referred to as “Bacteria A”, it mainly resides in the small intestine and is the most abundant bacteria in the small intestine. It has its traces in the vaginal wall, cervix and urethra. Studies have shown that Lactobacillus acidophilus can lower cholesterol, regulate immunity, and reduce the infection of Candida vaginitis.
Lactobacillus brevis: It exists in the human mouth, mouse tail and intestine, as well as in milk and cheese. Studies have found that Lactobacillus brevis can inhibit intestinal pathogenic bacteria, maintain the function of the digestive tract, promote appetite and immunity adjust.
Lactobacillus casei: referred to as “C bacteria”, this bacteria is quite acid-resistant, with a survival pH of about 3, just within the pH range of gastric acid, which can effectively pass the test of gastric acid choline, and has a large scale enter the intestinal tract for reproduction. Studies have found that Lactobacillus casei has the functions of lowering blood pressure, lowering cholesterol, promoting cell division, producing antibody immunity, helping to prevent cancer and inhibiting tumor growth, as well as relieving lactose intolerance, allergies and other health care effects.
Lactobacillus paracasei: referred to as “LP bacteria”, it is also resistant to gastric acid and bile salts, and has a good colonization effect in the intestine. On the one hand, it promotes the secretion of cytokines in the body, and on the other hand, it inhibits the sensitive immune response caused by cells , to balance the immune system, may be effective for allergic symptoms such as atopic dermatitis, allergic rhinitis, allergic conjunctivitis, allergic asthma.
Lactobacillus delbrueckii subsp. Bulgaricus: It is a subspecies of Lactobacillus germanium and is widely used in the production of yogurt. It has the functions of regulating gastrointestinal health, promoting digestion and absorption, increasing immune function and assisting Anti-tumor and other effects.
Lactobacillus rhamnosus GG: referred to as “LGG bacteria”, is currently the most studied probiotics in the world. Studies have found that Lactobacillus rhamnosus GG strain can promote and activate immune function, and at the same time can help the growth of other beneficial bacteria, reduce allergies to dairy or food, and treat acute diarrhea.
Bifidobacterium
Bifidobacterium bifidum: referred to as “B bacteria”, it helps maintain the acidic environment of the intestinal tract, reduces the reproduction of harmful bacteria, enhances immunity, lowers cholesterol, improves constipation and regulates the physiological function of the intestinal tract.
Bifidobacterium infantis: It is found in the intestines of infants, so it is called “Bifidobacterium infantis”, which can slow down the inflammatory damage caused by the overreaction of the human immune system .
Bifidobacterium lactis: It is isolated from the feces of healthy infants and is one of the most common flora in the human intestine. It is resistant to gastric acid and bile salts, and can relieve gastritis and improve lactose intolerance.
Bifidobacterium longum (Bifidobacterium longum): Bifidobacterium longum is the main beneficial bacteria in the intestinal tract, and it is also a real human protozoa, which can effectively regulate the cellular immune response and reduce the content of allergy-causing antibody IgE in the blood of allergic patients. In turn, it can effectively improve allergic symptoms caused by pollen, and can also improve diarrhea caused by antibiotics and food pathogens.
Bacillus
Bacillus coagulans: Studies have found that it can treat acute and chronic diarrhea, chronic constipation, bloating and indigestion caused by intestinal flora imbalance.
Clostridium
Clostridium butyricum: also known as “Clostridium butyricum”, “butyric acid bacteria” or “Miyagi bacteria”, it can prevent chronic diarrhea, antibiotic-related enteritis, constipation or alternating diarrhea and constipation and other symptoms, and help to adjust the intestinal tract Road function.
Can every body type be supplemented with probiotics?
Probiotics have many benefits to the human body. Most of the modern people are in a sub-health state, and most people’s intestinal bacteria are out of balance. If they can be supplemented in time, it will be of great help to health. However, is probiotics suitable for everyone? From a health point of view, it is suitable for everyone to eat, but only in moderation.
Although probiotics are suitable for the vast majority of people, patients with immunodeficiency, infants, premature babies, pregnant women, extremely weak people, cancer and other patients must discuss with a doctor or nutritionist before using them; on the other hand, if Long-term use of sugar-sweetened yogurt as a probiotic supplement will increase the risk of sugar and obesity, and is not beneficial for patients with poor blood sugar control.
As for some studies, probiotic supplementation in severe and sepsis patients may increase the chance of infection. Bacterial infection in critically ill patients is often caused by the translocation of bad bacteria, rather than probiotics. If good intestinal bacteria are supplemented, the probability of infection is not high. Clinical treatment still tends to let critically ill patients supplement with probiotics.
