Since four thousand years the human race is using lactic bacterias for the fermentation of foods. These bacterias are used in the whole world, in particular in milk products such as yogurt, cheese, butter and kefir.
The benefits of yogurt and lactic acid-producing bacteria such as yogurt species have been investigated in numerous studies in recent years. Studies showed promising health benefits for certain gastrointestinal conditions, including lactose intolerance, constipation, diarrheal diseases, colon cancer, inflammatory bowel disease, Helicobacter pylori infection, and allergies. The benefits of yogurt consumption to gastrointestinal function are related to effects mediated through the gut microflora, bowel transit, and enhancement of immune responses.
The main benefit of probiotics is to improve the intestinal tract health. Probiotics improve the intestinal health tract by adhering and colonizing the gastrointestinal tract, interacting with a wide range of specific human epithelial cells, thus modulating and improving the immunity of the gastrointestinal tract.
A vast variety of different species of good microorganisms are found in kefir. This is why it is actually so healthy. Because kefir is such a balanced and nourishing food, it contributes to a healthy immune system and has been used to help patients suffering from different disorders.
Kefir is reported to have various health benefits such as anti-tumour, anti-inflammatory, anti-neoplastic (inhibiting or preventing the development of abnormal biological tissue or organ) and pro-digestive effects. It has been shown to control several cellular types of cancer.
