? Intestine is an important digestive organ, the largest detoxification organ and the largest immune organ, so why is it the largest?
? Because there are intestinal villi in the intestine, each intestinal villi will increase the contact surface. If our intestines, including folds, are completely spread out, its contact area is equivalent to the area of a 200㎡ house, so it is the largest contact area between the human body and the outside world and the largest contact organ of our human body.
Intestine is the largest digestive organ, detoxification organ and immune organ of human body, and it is also the first organ of human body to age.
Around the age of 25, the intestinal function will be gradually affected and decreased, which is closely related to the flora in our intestines. There are more than 500 kinds of intestinal flora in normal adults, the number of which is about 1 000 trillion, which is the largest microecological environment of human body. The total weight of all strains reaches 1.5kg, which is equivalent to the weight of1liver or 4 hearts. Therefore, intestinal flora will affect our digestion, detoxification and immunity, and our health can not be separated from intestinal flora and such a microecological environment.
Second, the intestine is roughly divided into three kinds of bacteria.
1, beneficial bacteria, that is, probiotics we often say, are closely related to our human health, and it can synthesize a variety of vitamins; Participate in the digestion of food; Promote our intestinal peristalsis; Inhibit the growth of pathogenic bacteria; Decomposition of harmful and toxic substances.
2. Harmful bacteria, as the name implies, are harmful to health. In the intestinal flora, it and beneficial bacteria account for 20%-30% respectively. If harmful bacteria are out of control, in the case of mass reproduction, it will lead to a variety of diseases, such as abdominal distension, diarrhea, constipation, etc., which are related to harmful bacteria, and at the same time, it will also produce some carcinogens that affect health.
3, neutral bacteria (that is, conditional bacteria 40%-60%), like grass, have a dual role, that is to say, it will tend to a large number of strains, for example, when the number of beneficial bacteria is greater than harmful bacteria, neutral bacteria will follow the team of beneficial bacteria, and the body is in a healthy state at this time. On the contrary, if there are more harmful bacteria, neutral bacteria will be biased towards harmful bacteria, which will cause some unfavorable factors to the body, that is to say, the nature of our neutral bacteria will change with the human body.
4. The flora that should be paid attention to in weight management.
90% of the bacteria in the intestinal flora belong to two categories: Firmicutes and Bacteroides. Firmicutes can help the human body effectively absorb energy in food and quickly convert it into fat for storage. On the other hand, Firmicutes can also regulate the gene expression of our energy storage, that is, change our physique. Many studies have confirmed that there is a high correlation between obesity and people with a large number of scleroderma in the intestine.
Bacteroides, on the other hand, absorbs energy at a relatively low rate and is good at decomposing carbohydrates. It is not easy to convert the absorbed energy into fat for storage. The study also shows that people with high bacteroides content are not easy to gain weight.
? Sweet food, a lot of meat and fried food are all high in sugar, fat and calories, and the cellulose will be relatively low, so the food with a structural proportion will lead to the frequent increase of Firmicutes. Then, on the contrary, if you eat some balanced and nutritious food at the same time. At this time, the number of bacteroides will increase. In other words, the adjustment of diet structure will affect the changes of our intestinal flora and also change our body shape.
? Intestinal conditioning cycle is more than two weeks, so the catering diet is basically more than two weeks to achieve the most basic cycle of intestinal conditioning. A key step of weight management is to adjust the changes of intestinal flora, so as to maintain a healthy weight and not easily rebound. Because it will not only affect the changes of flora in our intestines or change our body shape, but also change our physique, so that it is not easy to gain weight, which is what we often call lean physique.
Third, the flora in our intestines is not innate. Actually belongs to outsiders. How did it come from?
? In the mother's womb, our fetus is basically in a sterile environment. In the days after the birth of the fetus, bacteria will enter the body through vaginal substance intake during childbirth, oral intake during breastfeeding and air inhalation in the later period, and bacteria will colonize in our intestines, forming the initial intestinal flora of newborns. As the baby grows up, the species structure of our intestinal flora will gradually stabilize, and mature intestinal strains will be formed in the early infancy. At this time, probiotics are dominant and the number will be more.
As adults, we begin to contact different diets, and even some partial eclipse and picky eaters will cause acid-base imbalance in the body. In addition, some drugs are used in our diseases, and some antibiotics are frequently used at present, which leads to acid-base imbalance in the body and decreased immunity. This will cause intestinal flora imbalance, leading to a gradual increase in the number of harmful bacteria and a relative decrease in the number of beneficial bacteria.
? In middle-aged and elderly people, our whole body functions will naturally age, at the same time, our metabolism will also decline, and the vitality of the intestines will naturally decline. Therefore, even if the whole body is in good health during this period, it is difficult to avoid the aging of intestinal flora. Moreover, our intestines begin to age around the age of 25, so the adjustment of the whole intestine and the maintenance of flora balance should be as early as possible, especially before we reach adulthood. This is the best time to help adjust the proportion of intestinal flora.
Thirdly, the regulation of intestinal tract can be summarized as three main steps:
First, clear. Remove harmful substances in the intestines, and there are many harmful bacteria. At this time, we need to clean up our intestines.
Second, raise. Is to cultivate, cultivate, and put a lot of beneficial bacteria into our bodies. At this time, we will supplement our beneficial bacteria.
Third, decide. Eliminate harmful bacteria and cultivate beneficial bacteria, and plant a good proportion of flora in our intestinal flora. Cultivate the proportion of flora in the whole intestinal environment to maintain the health of our intestines.
