1, intestinal flora balance and human health The intestine is one of the most strenuous organs of the human body, more than 95% of the body’s nutrients are absorbed from the intestine, while 99% of the toxins are also entering the body through the intestine. It is also the largest micro-ecosystem in the body, with more than 500 kinds of flora living in it, and the intestine is in charge of more than 70% of the body’s immune function. Healthy human body between the beneficial bacteria and harmful bacteria interdependent, to the constraints of the micro-ecosystem in a dynamic balance, but when the human body encountered various changes in the environment, the balance of the flora is broken, the number of beneficial bacteria decreased, the number of harmful bacteria increased, the human body will be followed by a variety of diseases. 2, healthy intestinal guardian – probiotics Probiotics on the human body in the end what health care and anti-disease effects? Some foreign scholars believe that its role can be summarized as follows: ① solve the long-term diarrhea and constipation caused by irritable bowel syndrome; ② relieve the symptoms of lactose intolerance; ③ prevent fungal infections; ④ relieve the role of allergies and enhance human immunity; ⑤ promote intestinal digestive health; ⑥ reduce serum cholesterol; ⑦ prevent cancer and inhibit tumor growth; ⑧ protect the liver and kidney; ⑨ maintain the health of smokers. ①Solve chronic diarrhea and constipation caused by irritable bowel syndrome: poor diet or taking antibiotics can break the balance of intestinal flora, which leads to diarrhea. Probiotic supplementation can help balance intestinal flora and restore normal intestinal pH to relieve diarrhea symptoms. ② Relieve the symptoms of lactose intolerance: Lactobacillus can help the body break down lactose and relieve diarrhea, flatulence and other uncomfortable symptoms, which can be consumed with milk. ③Prevent fungal infections: Lactobacillus acidophilus in sour milk can inhibit the reproduction of Candida albicans in the vagina. This was confirmed in a double-blind controlled trial done in Europe. In a double-blind controlled trial conducted in Europe, women who received 150 ml of sour milk containing high levels of probiotics orally per day each had a much lower incidence of vaginal infections than women in the placebo group. This is because the Lactobacillus acidophilus in sour milk inhibits the growth of Candida albicans in the vagina. ④Allergy relief and immune system enhancement: There is a very well-developed immune system in the intestinal tract. Probiotics can regulate the immune activity that is too low or too high to a normal state by stimulating the immune function in the intestine. This immunomodulatory effect of probiotics is also believed to help fight cancer and suppress allergic diseases. ⑤ Promote intestinal digestive health: Probiotics can inhibit the proliferation of harmful bacteria in the intestine, reduce toxins and promote intestinal peristalsis, thus improving intestinal function and bowel movement. ⑥Lowering serum cholesterol: Europe’s Caucasus mountains and Mediterranean coast are famous for longevity, and local people often drink homemade sour milk, rarely suffer from diabetes, cardiovascular disease and obesity, and a lot of scientific research has confirmed that this is related to the richness of probiotics in sour milk. These probiotics can reduce serum cholesterol levels, in addition, long-term supplementation of probiotics can also help prevent bone loss and osteoporosis. (7) Preventing cancer and inhibiting tumor growth: To put it simply, probiotics can adsorb carcinogens and process or transfer carcinogens, reducing their toxicity. Probiotics can help the body to keep away from harmful bacteria and harmful enzymes, so they do not have the opportunity to process carcinogens ⑧ Protect the liver and kidney: many scholars have used probiotic preparations for the treatment of liver disease. Scientists door had introduced bifidobacteria to the intestines of liver disease patients, and found that the sick people’s blood ammonia decreased, while appetite increased, which helped the recovery of liver disease. Probiotics applied to the treatment of cirrhosis, hepatitis, the results proved that Ming can effectively improve the liver protein metabolism function, reduce the level of endotoxin in the blood. ⑨ Maintain the health of smokers: “American clinical research” probiotics can reduce the damage condition of blood vessels of smokers, probiotics can reduce LDL level and improve HDL level, while probiotics have a positive effect on the response and level of insulin in human body. 3.Supplementation principles Premature babies, C-section babies: need to supplement a variety of effective probiotics a week after birth to help babies form a healthy intestinal flora to avoid the occurrence and aggravation of allergic symptoms. Babies with eczema, constipation, thrush, bacterial diarrhea, indigestion, allergies, and those on antibiotic medication need probiotics. Babies who play antibiotic medication: within 2 hours of using medication, it is necessary to supplement lactoferrin, and after 2 hours, probiotics and mineral zinc to avoid disorders of the baby’s intestinal flora that make the baby have more than diarrhea and avoid the side effects of antibiotics on the baby. Need to adhere to supplementation for 3 months, in addition to a comprehensive, balanced and adequate supplementation of all other required nutrients. Probiotics are the green antibiotics, known as the post-antibiotic era alternatives! We usually take oral antibiotics and anti-inflammatory drugs to solve minor problems, such as: cold and fever, sore throat, diarrhea and constipation, bacterial infections, etc., today you can use probiotics to solve, it not only plays the role of antibacterial and anti-inflammatory, but also very safe for our body. Probiotics can promote the absorption of a variety of nutrients, which is especially suitable for pregnant women and infants with poor digestive and absorption functions. Probiotics can effectively reduce the incidence of diarrhea and constipation when infants and toddlers are switched to milk. Pregnant women who have poor appetite, eat less, have poor digestion and are prone to constipation need to supplement probiotics. When supplementing probiotics, it is best to add a small amount of probiotics to extend the life of probiotics. 4, common allergy symptoms in babies Common allergies in infants and children are: gastrointestinal symptoms caused by food allergies, allergic asthma and rhinitis, eczema. Reasons for the occurrence of eczema: eczema is the most common allergic condition in infancy. According to medical research, it is proven that the root cause of allergies is the dysbiosis of the intestinal system in the body. When babies are first born, their immune system is immature and relatively susceptible to infections and allergies, while probiotics can speed up its maturation and make it sturdy, thus preventing the occurrence of allergies. The latest research shows that the higher the number of probiotics in the baby’s intestine, the smaller the chance of allergies. Proper supplementation of probiotics can effectively fight against allergies. Because the baby’s own immune system is not yet mature, maternal antibodies gradually disappear after birth, and the baby is in the susceptible period in the first 6 years after birth, many babies will have gastrointestinal function, imperfect immune function, weak body resistance, digestive disorders, intestinal malabsorption and infectious diseases, etc. These small states not only hinder the physical growth and development of the baby, but also have a negative impact on the development of the baby’s intelligence and cognition, and the development of emotional and social skills, For therapeutic chemical drugs, mothers are bound to worry about the harm brought to their babies, while probiotics, a unique natural ecological therapy to bacteria, by maintaining the balance of the intestinal flora, maintain the dominance of probiotics, improve the baby’s immunity, promote gastrointestinal digestion and absorption, prevent various diseases, and guard the healthy and balanced growth of each baby. 5.How to preserve probiotics Probiotic products must be stored in low temperature refrigeration. This can maximize the number of active probiotics. General shelf life within 1 month, refrigerated temperature control at about 2-10 ℃. It is recommended to put in the refrigerator fresh layer, avoid in the temperature is too high or direct light preservation, which will cause excessive fermentation of live bacteria inside, the taste becomes sour, the effect is affected. 6, precautions (1) brewed milk powder or preparations containing probiotics, pay attention to the use of warm boiled water (35 ~ 40 ℃) to baby, brewed milk or probiotic preparations should be taken in time to avoid the death of probiotics failure. (2) Probiotics can not be taken with antibiotics. Antibiotics, especially broad-spectrum antimicrobials, cannot identify harmful bacteria and beneficial bacteria, so it often kills the beneficial bacteria when it kills the enemy. Supplementing probiotics after taking antibiotics can play a good role in maintaining the balance of intestinal flora. (3) Babies over 1 year old can drink probiotics. Especially for babies with loss of appetite, constipation, frequent diarrhea or indigestion, long-term choice of probiotics can also regulate gastrointestinal function. (4) Foods for probiotics are fiber, lactose, starch and oligosaccharides; so while supplementing probiotics, you should eat more root vegetables, fruits and seaweed and other foods, which is the same as arranging an environment in the intestines that they like to grow. Most of the probiotics do not like meat and glucose, if the food containing probiotics contains too much sugar will also reduce the activity of the strain. (5) If there is no indigestion, bloating, diarrhea or other factors that disrupt the balance of intestinal flora, additional intake of excessive probiotic preparations for infants and children is not advocated.
