The gastrointestinal tract represents the most extensive interface between the human organism and the external environment. The human gastrointestinal tract is settled by a complex microbial ecosystem, in which microbiota, nutrients and host cells interact extensively. This is a crucial process for intestinal homeostasis and the establishment of a true partnership with the host. The various bacterial communities that make up the intestinal flora have many functions, including metabolism, barrier function and nutritional function. The relationship between intestinal flora and human health is increasingly recognized. It has now been determined that a healthy intestinal flora is mainly responsible for the overall health of the host.

About 100 trillion bacteria live in the human intestine. These intestinal bacteria look like lush bushes, so they are also called “intestinal bacterial clumps”. Among the 100 trillion https://www.redhatsafety.com/ intestinal bacteria, bifidobacteria are the best probiotics, not only can make people healthy and longevity, but also beneficial to body shaping and beauty. There are good and bad bacteria in the intestinal flora that move in the intestine. If bifidobacteria, which is very beneficial to the human body, increase, it can help us “wash” the intestines.

Maybe you can’t imagine how huge the number of 100 trillion is. To put it in an analogy, there are about 4.5 billion people on the earth, and one hundred trillion is more than 20,000 times the 4.5 billion. If the bacteria in a person’s intestine are arranged in a row, the length of the bacteria can go around the earth more than 2 times.
