May 29th is World Intestinal Health Day. As an important organ of the human body and the largest immune organ, the gut actually accounts for 70% -80% of the body's resistance. Therefore, gut health is very important for each of us. Imbalance of gut microbiota can easily lead to diseases. The bacteria in the gut are collectively referred to as "gut microbiota", and the number of gut microbiota is unimaginable. There are nearly 1000 to 1150 types of bacteria in the human gut. The imbalance of the bacterial community can easily trigger various diseases. The intestinal flora likes to live in the deepest part of the intestinal tract. A large number of intestinal bacteria mainly live in the colon and the distal small intestine. Their density distribution decreases from the distal end of the intestinal tract to the proximal end, and from two directions outside the intestinal cavity. Bacteria are divided into beneficial, harmful, and neutral bacteria. Beneficial bacteria can help us digest food and absorb vitamins; Harmful bacteria may cause various diseases; Neutral bacteria, also known as "conditional pathogens," only become pathogens when the "environment" is not good. Optimizing the microbial community structure is beneficial for calcium absorption. Many people believe that drinking milk and bone soup can supplement calcium, but simply supplementing calcium cannot prevent osteoporosis. If the microbial community is dysregulated and the absorption capacity is poor, supplementing calcium is naturally useless. The close relationship between gut microbiota and osteoporosis has been increasingly confirmed by research - calcium absorption in patients with osteoporosis is the result of the interaction between estrogen levels, gut microbiota, and the host immune system. When estrogen levels are insufficient, the types of gut microbiota decrease, the barrier effect weakens, and the immune response is abnormal. Appropriate microbiota can have a certain therapeutic effect on osteoporosis by changing these adverse states; At the same time, the gut microbiota can produce estrogen metabolites, playing a replacement role. Moreover, compared to some drugs with side effects, gut microbiota can become a safer treatment strategy. Therefore, adjusting the structure of gut microbiota, promoting the growth of beneficial microbiota in the gut microbiota, and reducing the proportion of harmful microbiota have significant implications for maintaining bone health. Poor dietary habits can easily lead to dysbiosis of the gut microbiota. In daily life, there are two factors that can easily lead to dysbiosis of the gut microbiota. Eating foods high in oil, salt, fat and protein for a long time in an unbalanced diet will reduce the number of beneficial bacteria such as bifidobacteria and lactobacilli in the body, and increase the number of harmful bacteria such as Enterococcus and Enterobacteriaceae, causing intestinal flora imbalance. Not paying attention to dietary hygiene can cause harmful bacteria to adhere to food and water and enter the human body, growing crazily in the nutrient rich and temperature appropriate environment of the intestine, leading to imbalance of the gut microbiota. Adjusting the gut microbiota in this way is beneficial for bone protection. To solve osteoporosis, it is not necessary to rely solely on calcium supplementation. Adjusting the gut microbiota can be a good way to improve osteoporosis. Pay attention to dietary patterns and have sufficient water intake every day; Strengthening physical exercise, such as aerobic exercise such as walking and cycling, can effectively improve constipation; Maintain a fixed time for defecation, usually starting in the morning and two hours after meals for regular bowel movements; Eat more fiber rich foods. Coarse grains, fruits, and fresh vegetables are all good sources of dietary fiber, such as celery, cucumbers, apples, bananas, etc. Eat less junk food with high sugar and fat. In addition, you can choose to supplement high-quality probiotics. Probiotics as
