What are probiotics?
Of course, pathogenic germs can spoil food and lead to massive gastrointestinal infections - but that's just one side. Other bacteria have been used in food production for centuries because they are needed for the production and preservation of cheese, yogurt, as well as sauerkraut or beetroot. For many years, the generic term probiotics has been used to sell many products containing large quantities of lactobacilli or bifidobacteria. Most are yoghurts, but now there is also sausage and cheese with probiotic properties.
Importance of probiotics for our digestion
The bacterial strains survive in large numbers the attack of gastric and bile acids, get into the small and large intestine and there - but only with regular ingestion - displace other, not so friendly minded bacterial species. Probiotic bacteria promote digestion - especially in lactose intolerance - and mitigate the course of diarrhea. During pregnancy, they seem to lower the risk for the baby to get eczema or allergies. It also discusses positive effects on cholesterol and colorectal cancer risk.
Living with or without bacteria?
Because of human disequilibrium among the micro-organisms, one could conceivably kill all human germs in order to get around this problem - unfortunately, animal studies have shown that this sterility leads to a fatal infection already occurring. So only the middle ground and the arrangement with our "roommates" remain: Take measures to maintain the protective normal flora, eg help your digestive system with additional lactic acid bacteria, and if possible avoid medications such as antibiotics or massive disinfectants and cleansers, which disturb the sensitive system of bacterial diversity.
