Bifidobacteria colonize the digestive system (including the appendix) of healthy people as well as the vagina of healthy women. You keep harmful bacteria and pathogens away. The settlement of bifidobacteria in the intestine and/or vagina can be achieved with the help of high-quality probiotics. At the same time, the diet must be rich in indigestible carbohydrates (fiber) so that the bifidobacteria find enough food and also really settle permanently.
Bifidobacteria for a healthy gut
Researchers have identified more than twenty years ago that bifidobacteria are among the most important components of the intestinal flora. In adult humans, their share in the total intestinal flora is about 25 percent, while it reaches even 95 percent in newborns. The scientists had shown that the number of bifidobacteria can be specifically increased when abundant carbohydrates are eaten.
Bifidobacteria keep harmful intestinal bacteria away
Bifidobacteria decrease (like lactobacilli) the pH in the colon, by fermenting glucose to lactic acid. Undesirable intestinal bacteria and pathogens such as Salmonella, putrefactive bacteria or E. coli bacteria like such an acidic environment in the colon not and can hardly settle, therefore, and if they do, so they cannot multiply excessively and are to the “good” intestinal bacteria – such as bifidobacteria – kept under control.
Bifidobacteria in breast milk
Bifidobacteria are transmitted through the breast milk to the infant. Therefore, breastfed babies have, compared to non-breastfed to a significantly higher proportion of these microorganisms in the intestine. Bifidobacteria are able to survive the extremely acidic conditions in the stomach and then mainly to settle in the large intestine of infants, where they multiply rapidly. Babies thus obtain a natural protection against pathogens via breast milk. This fact also explains why breastfed infants have much less to infections than babies fed with conventional industrially produced infant milk.

In addition to the bifidobacteria, breast milk seems also to contain substances that accelerate the growth and proliferation of the intestinal bacteria. Studies have proven that the growth of bifidobacteria is stimulated by the addition of milk. Bifidobacteria against vaginal infections
Bifidobacteria colonize not only the intestines and the digestive system but also the female vagina. So the friendly bacteria not only protect our digestive tract from infection but also the vagina.
Bifidobacteria stimulate the immune system
However, bifidobacteria can do much more. They are known to communicate about specific signaling pathways with our immune system and stimulate as such. An Example can be the antibody production and the growth of certain immune cells. Moreover, they produce vitamins that we can get through the intestinal mucosa. The little helpers of our intestinal flora are so true heroes of the defense.
Diet changes the intestinal environment
The composition of the intestinal flora is extremely dependent on diet. A diet that is high in fat and meat, feeds the harmful intestinal bacteria that produce numerous toxic substances from unhealthy foods. These include the liver poisons ammonia and different amines as well as nitrosamines, phenols, cresols, and carcinogenic endogenous estrogens that can contribute to the formation of primary breast cancer. In addition, bile acids may arise which favor the development of colorectal cancer. If then also alcohol is enjoyed, and then boosts the productivity of the poor intestinal bacteria only and more and more intestinal toxic substances are formed. A healthy alkaline diet with probiotics is therefore particularly important to promote proper bowel bacteria and allow the wrong to starve.
