The intestine is the largest digestive organ of the human body and the largest detoxification organ of the human body, as well as our “second brain”. It can be said that intestinal health not only affects the overall health of the body, but also affects our emotions, so maintaining intestinal health is the key to ensuring our health and happiness. Intestinal health, where does it come from? Constipation, diarrhea, indigestion …… When these symptoms appear, we know that there is something wrong with the intestinal tract. But, did you know? In addition to changes in the intestinal tract itself, intestinal health is actually largely influenced by the intestinal flora. The process of beneficial bacteria overcoming harmful bacteria in the gut is the process of building up gut health. There are a large number of bacteria living in our intestines, about 10 times the total number of our human cells, with a total weight of up to 1.5-2 kg. They can be divided into beneficial bacteria (such as butyric acid-producing Clostridium casei, lactic acid-producing Lactobacillus, Bacillus coagulans, etc.), harmful bacteria (such as hemorrhagic Escherichia coli) and intermediate bacteria (such as Enterococcus). In a healthy state, the number of beneficial bacteria is significantly higher than the number of harmful bacteria, accounting for more than 75% of the total intestinal flora. When there is a problem in the intestine, the harmful bacteria will proliferate and the number of beneficial bacteria will decrease. The intermediate bacteria are the grass on the wall, which side of the power will fall to which side. Therefore, in daily life, maintaining the absolute advantage of beneficial bacteria in the intestine is the key to ensure intestinal health. Intestinal health, what are you afraid of? 1, bad diet The bacteria in the intestine mainly feed on what we eat, healthy diet to raise healthy flora, junk food, high-fat diet and other unhealthy diet can also lead to imbalance in the flora. 2, drug abuse Taking antibiotics, antipyretic and analgesic drugs, chemotherapy drugs, etc., will stimulate the intestinal mucosa and disrupt the balance of intestinal flora. It causes antibiotic-related diarrhea, irritable bowel syndrome, chemotherapy-related diarrhea and other intestinal health problems. 3, bad emotions Hate, grief and other bad emotions can affect intestinal health through the brain-gut axis. Studies have found that bad emotions can make the colon will appear non-peristaltic high motor state; sadness, disappointment, intestinal peristalsis increased leading to diarrhea; fear and frustration, the colon no contraction activity. 4, ageing Each of us can not escape the ravages of age, the intestines are the same. From birth, our intestinal flora began to gradually establish, after reaching a stable period, the proportion of probiotics generally account for more than 80% of the total intestinal flora, the number of probiotics in middle and old age will gradually decrease with age, while the number of harmful bacteria increased, leading to long-term constipation, foul-smelling stools and intestinal flatulence. How to maintain a healthy intestinal tract? On the basis of understanding the above information, the intestinal health care methods will be whistled. 1, to healthy diet three meals a day should be meat and vegetables, appropriate to reduce the growth of high protein, saturated fatty acid foods that are not conducive to the beneficial flora, eat more vegetables rich in dietary fiber, fruits, potatoes, whole grains and other foods. Intervention can also be done through the intake of finished dietary fiber. 2, avoid the abuse of drugs such as the above-mentioned antibiotics, aspirin, Protaxon, indomethacin and other antipyretic and analgesic drugs, etc., must be used with caution. Of course, this is not to let everyone eliminate the use, in case of necessity can be used reasonably, but when there is room for choice, do not abuse. 3, supplement probiotics oral probiotics into the intestine, can defeat harmful bacteria, restore the balance of intestinal flora, in order to improve intestinal function and maintain intestinal health. Especially for people who already have intestinal problems, it is more necessary to supplement probiotics. For the aging of the intestinal tract caused by ageing, people should start supplementing probiotics to take precautions whether they show symptoms of intestinal discomfort or not in middle age. Bacillus coagulans and Clostridium casei preparations that can supplement probiotics and promote the synergistic proliferation of bifidobacteria and lactobacilli, as well as inhibit the growth of harmful bacteria, are good choices.
