Among the controllable factors affecting intestinal health, diet is the most crucial one, beneficial bacteria can be directly supplemented by yogurt, lactobacillus drinks and other probiotic drinks; on the other hand, it is also important to eat more dietary fiber, because it is fermented in the intestine to produce short-chain fatty acids, which can provide “nutrients” for the growth of probiotics, and can also improve the bowel movement ability. Therefore, what to eat and how to eat is very critical. Throughout the past decade, the relationship between nutrition and intestinal health has become more closely linked with the high incidence of intestinal tumors and the increased use of antibiotics. In clinical and daily life, there are two major changes: First, probiotics are becoming more widely used in clinical settings. Many hospitalized patients suffer from diarrhea, and after prescribing probiotics to them, they can often achieve more obvious relief; secondly, under the propaganda of experts in nutrition and gastroenterology, people gradually realize the importance of keeping the balance of intestinal flora, and the awareness of probiotic products is gradually increasing, and more and more people start to choose probiotic drinks in their daily life. It should be reminded that when we take care of intestinal health, there are still some misconceptions, usually we should keep in mind the following 4 points: 1, the most important dietary balance. Keep in mind the recommendations of the Chinese dietary pagoda, do: food diversity, cereal-based, coarse and fine mix; usually eat more fresh fruits and vegetables and potatoes; every day to supplement milk, soy and its products. 2, dietary fiber can not be less. Dietary fiber can help us create a better intestinal environment, promote the reproduction of beneficial bacteria to check and balance the harmful bacteria. It also has the ability to prevent constipation, lower cholesterol, prevent intestinal cancer and other effects. So we should consciously eat more mixed grains, potatoes and fresh vegetables and fruits, etc. 3, the correct choice of probiotic products. We emphasize that probiotics should be sufficient and “alive” to reach the intestine, so when choosing probiotic products, we should pay attention to whether it can resist the strong bactericidal effect of digestive juices such as gastric juice and bile, and can reach the intestine in an active state. Not all products on the market can do this, so you have to choose to “fire the eyes”. At the same time, the cold chain of probiotic drinks is also crucial, in the sale of transport and storage should be low-temperature preservation; we buy from the supermarket to home should be promptly put in the refrigerator, if you feel too cold to drink in winter, can be placed at room temperature for an hour or two before drinking. Equally important, we should pay attention to identify lactobacillus drinks and drinks containing lactic acid, the former contains probiotics, the latter is just blended out of milk powder, lactic acid, sugar and so on. 4, probiotic drinks are best to drink after meals. After a meal, the acidity in the stomach is low, and it is relatively easy for probiotics to live through the stomach to reach the intestines. In addition, when taking antibiotics, as antibiotics are more likely to kill the relatively fragile beneficial bacteria, so the probiotic supplement should be doubled, but must be staggered with the time of taking antibiotics for more than 1 hour. Finally, probiotic drinks are recommended to drink every day, because even the best strains of bacteria can not reside in the intestine for a long time. Let’s do a intestinal care people, pay attention to intestinal health, keep the intestinal tract young, together to approach the secret of “intestinal life”!
