Middle-aged people eat probiotics, which can bring us many benefits, so we should drink more probiotics in our daily life. Let's take a look at the specific role and efficacy of middle-aged people eating probiotics. Welcome to forward!
Function and efficacy of probiotics in middle-aged people 1 1, physiological and intestinal characteristics in old age
After entering old age, the metabolic function of human body declines, especially the changes of digestive system.
For example: teeth fall off, affecting chewing function; The tongue taste buds atrophy, taste cells decrease and the salty threshold increases. The secretion of saliva, digestive juice and digestive enzymes decreases, which affects the absorption and utilization of food. In addition, the rate of esophageal peristalsis and gastrointestinal emptying in the elderly is reduced, and the time for defecation to pass through the intestine is prolonged, which makes the stool hard and constipation often occurs.
It is worth emphasizing that because there are hundreds of different bacterial flora living in the intestine, factors such as diet, antibiotic treatment and environmental exposure will change the bacteria in the intestine. In healthy children, 70% of intestinal bacteria are probiotics, while the proportion of probiotics in adult intestinal bacteria is only 10% ~ 15%, and the proportion is even lower after 60 years old. In old age, the number of probiotics in the body is greatly reduced, the resistance is reduced, and intestinal infections are more likely to occur. Therefore, the elderly need to supplement probiotics.
2. Cultivate intestines with bacteria and cure bacteria with bacteria.
Probiotics are living microorganisms that can maintain the balance of human intestinal flora and promote human health.
Microecological regulators in probiotics can not only prevent diseases, regulate human microecological imbalance, maintain intestinal microecological balance and improve human health, but also use the principle of biological antagonism to achieve the therapeutic purpose of treating bacteria with bacteria. Probiotics, in particular, have rapid onset and long-lasting effects, and have irreplaceable therapeutic and health care functions, greatly changing the methods and standards for human use of antibiotics.
With the rise of microecological theory, medicine has moved from the era of bacteriostasis to the era of promoting bacteria. "Treating bacteria with bacteria" means to colonize beneficial bacteria in the intestine, inhibit the reproduction and proliferation of harmful bacteria, and make the human body reach a healthy state. A great deal of research and medical practice have found that microecological preparations made of probiotics such as intestinal bifidobacteria, lactobacillus and streptococcus faecalis can effectively supplement human intestinal bifidobacteria, lactobacillus and streptococcus faecalis, adjust the microecological balance of intestinal tract, play a health care role and make the intestinal tract younger.
3. What are the effects of probiotics on the health of the elderly?
◆ Helps to synthesize vitamins necessary for human body;
◆ Probiotics produce antibacterial substances such as butyric acid and acetic acid;
◆ Bifidobacterium can prevent the synthesis of nitrosamine, a carcinogen;
◆ Accelerate intestinal peristalsis and prevent the occurrence of colorectal cancer;
◆ It can directly absorb cholesterol and reduce the risk of coronary heart disease;
◆ Reduce the adverse reactions caused by radiotherapy.
The function and efficacy of middle-aged people eating probiotics II. Relationship between intestinal flora and human body
1, and its relationship with food digestion, absorption and nutrition
People's health is inseparable from the proper intake of protein, fat, vitamins, carbohydrates and trace elements. However, a series of complex processes such as absorption and decomposition in vivo are closely related to intestinal flora. Intestinal flora is a normal microorganism in human intestine, such as Bifidobacterium and Lactobacillus, which can synthesize various vitamins necessary for human growth and development. These nutrients play an important role in human health, once lacking, it will cause many diseases.
2. Relationship with body immunity
A large number of beneficial bacteria, such as Bifidobacterium and lactic acid bacteria, live in the intestine. These beneficial bacteria block or inhibit the invasion of intestinal mucosa by producing organic acids, hydrogen peroxide and other substances As antigen stimulation, intestinal flora can promote the development and functional maturity of immune system and enhance immunity.
3. Relationship with tumor
Some bacteria in intestinal flora, such as Escherichia coli, Clostridium, Enterococcus, Bacteroides, etc., can promote the combination of nitrite and amine in food to form ammonium nitrite with strong carcinogenic effect. However, some intestinal flora, such as Bifidobacterium and Lactobacillus, can degrade ammonium nitrite into nitrite and amine, which can inhibit cancer. Therefore, whether the intestinal flora promotes or inhibits cancer depends on which flora is dominant. In the case of intestinal microecological balance, cancer-inhibiting bacteria are dominant, so it is mainly to inhibit cancer.
4. Relationship with cholesterol absorption and bile acid metabolism
Some beneficial intestinal flora, such as colon flora, can reduce the absorption of cholesterol and the concentration of endotoxin in blood under the condition of microecological balance. In addition, hydrolases and reductases in colon microorganisms also participate in the metabolism and enterohepatic circulation of various host organisms.
5. Fermentation of food ingredients
Intestinal flora has metabolic function, and colon flora is decomposed into CO2, H2, short-chain fatty acid amine and indole after some fermentation, in which short-chain fatty acids can promote the absorption of calcium, magnesium and iron in colon.
6. Relationship with constipation
Healthy intestine and the balance of intestinal flora are inseparable. Under normal circumstances, beneficial bacteria are dominant in intestinal flora, such as Bifidobacterium and Lactobacillus. Normal stool contains 70-80% water, and the maintenance of water benefits from intestinal flora. Therefore, it is very necessary to maintain good health and keep beneficial bacteria in the intestine dominant. If there is no intestinal flora in the intestine (such as taking antibiotics to kill most intestinal flora), there will be no perfect combination of flora and water in the feces, which will be dry and hard, and constipation will be inevitable. It can be seen that intestinal flora is closely related to human health. If there is a problem in the intestine and the intestinal flora is disordered, then your health will also be threatened. Therefore, it is very important to protect intestinal health and establish the balance of intestinal flora ecosystem. Protecting human health and supplementing probiotics are effective ways to maintain or adjust intestinal microecological balance, prevent diseases and improve human health and immune function.
The role and efficacy of middle-aged people eating probiotics 3 The role and efficacy of probiotics
1, intestinal function
Probiotics can maintain the intestinal health of the host and inhibit the reproduction of harmful bacteria. Probiotics can also produce a variety of enzymes to participate in the process of food digestion, which is beneficial to the intestinal digestion health and enhance the intestinal immunity.
2, anti-cancer effect
Supplementing suitable probiotics can maintain the balance of intestinal flora and significantly reduce the incidence of intestinal cancer. Similarly, if the microecological balance of the intestine is broken and can't be repaired in time, then your intestinal health will definitely be affected, greatly increasing the chance of suffering from intestinal cancer.
3. Reduce blood lipids
Probiotics play a key role in maintaining intestinal health, because it can bind cholesterol and harmful fatty acids in the intestine, prevent them from being absorbed by the intestine, and also allow these unhealthy lipids to be excreted in time.
4. Promote the absorption of nutrients
When the intestinal tract absorbs calcium, iron and vitamins, it is necessary to maintain a good intestinal pH environment. The reduction of ph is beneficial to the absorption and utilization of these nutrients, and the products thanks to probiotics in the intestine can reduce the intestinal ph, promote the absorption of various nutrients, and maintain the metabolism of various functions of the host.
5. Relieve lactose intolerance
Some people have lactose intolerance, and then they can't absorb the nutrients in milk, but drinking yogurt can solve this problem. Because probiotics in yogurt can produce enzymes that promote lactose decomposition, it is beneficial to the digestion and absorption of lactose by the host and relieves diarrhea and abdominal pain caused by lactose intolerance.
