Probiotics are live, selected microbial strains that have a beneficial effect on the human body and when introduced into the body, they colonize in the digestive tract, especially in the large intestine, exerting a beneficial effect on the health of the host. The microbial strains, so that they can be included in the probiotics, must be thoroughly tested and meet several conditions. These microorganisms multiply in the gastrointestinal tract and are competitive for pathogenic microorganisms that cause infection. Probiotic bacteria are found in natural yogurts, sour milk, sauerkraut, pickled cucumbers. Many studies show a positive correlation between the consumption of probiotics and the risk of developing certain cancers. Probiotics are most likely to reduce the risk of developing colorectal cancer.
