Probiotics – such as a healthy probiotic food are?
Microorganisms that protect the bowel, strengthening the immune system and against cancer-keep – for many years, it is known that there are these health-promoting germs indeed: and in our intestines. You can also be taken in through food, especially yogurt, they should romp. But the advertising promises?
Probiotics for the intestinal flora
The gut is the largest immune system of the human body – who claimed that decades ago, was ridiculed, at best, mild. But in the meantime, this Knowledge is well established in medicine. Numerous studies have shown that diseases, is involved in our immune system or crazy plays, often his output in the intestine, or – Vice versa – the appropriate disease images can be improved by the support of the bacterial flora.
What probiotics are?
At this point, probiotics: These microbes are a natural part of our healthy intestinal flora. In addition, you can get in the Form of food or dietary supplements in the intestines, settle there, and the existing intestinal flora support – and in this way, our immune system stimulate, train, and strengthen. Particularly helpful turns out to be Lactobacilli (lactic acid bacteria) and bifidobacteria – their preventive and healing effects are proven now, however, with limitations:
- Not all strains of bacteria possess the corresponding effects in the studies demonstrated effects not only apply to the tested probiotic (which means that you are also others available)
- In the case of the intake via food only a small part of the health-promoting micro-organisms to reach the intestines – the other will be destroyed by the stomach and bile acid.
- In the case of food, the risk that due to improper storage or transport ways are no longer sufficient bacteria amount are available, there is also a disadvantage of the dietary supplements from the pharmacy (e.g., in the Form of capsules).
Probiotics are cucumbers included in lactic acid fermented foods – and not only since it yogurt drinks in small bottles in thick milk, Kefir and yogurt, Sauerkraut, beetroot and salt. Since time immemorial, these bacteria help to preserve food, because the strong acid production other harmful organisms have no Chance.
Effects of probiotics
Under the heading of “probiotic”, which means translated as much as “for life”, are the shelves of the grocery retailers now fully with a variety of products, almost all of their market share is more expensive than conventional products, at 15 percent. Not every consumer is immediately apparent the importance of the Lactobacillus casei Actimel or a Lactobacillus casei Golding and Gorbach (LGG). This – by the way, not genetically modified lactic acid bacteria have proved to be quite resistant to gastric and bile acid. In the meantime, there are numerous studies on the effect of probiotics:[1-9]
- In fact, certain probiotics, such as yeast (Saccharomyces boulardii) and bacteria Lactobacillus rhamnosus GG (for example, LGG or Lactobacillus acidophilus) can reduce the duration and Severity of gastro-intestinal infections and diarrhea diseases. You can even be used as a prevention against Travel diarrhoea (5 days before the start of the trip with taking start).
- Other bacteria promote digestion, and reduce the number of decay-forming bacteria in the colon; in the case of the milk sugar intolerance improve the digestion of lactose.
- In the case of small children, the consumption of milk protects acid bacteria with probiotic properties against certain intestinal infections, and helps to normalize the bacterial Overgrowth after antibiotic therapy.
- During pregnancy and breastfeeding from the mother ingested lactic acid bacteria (e.g., LGG®, Symbiolact comp.®) to prevent allergic reactions and specifically a eczema in the child.
- Probiotics seem to be the course of chronic to the influence of inflammatory bowel disease (ulcerative colitis, Crohn’s disease), and urinary tract infections positive.
- Possibly reduce probiotics, the risk for colon cancer, since they inhibit cell-damaging enzymes. A Japanese study has shown this effect for germ Lactobacillus casei Shirota.
- Possible disadvantage: It could be that you can worsen some diseases – diseases are affected there may be some autoimmune diseases, such as the Bechterew-disease.
It’s very important that you take probiotic products often, almost daily, and regularly. Otherwise, you will not be able to colonize the bacteria to the intestinal mucosa. Conventional, non-heat-treated yogurts and dairy products, the live Lactobacilli and bifidus strains of bacteria that are so beneficial to health. The DGE recommends a daily net intake of low-fat acidified milk products.
