probiotic, any of various live microbes, normally germs or yeast, that are ingested or otherwise administered as a means of potentially helping the avoidance and treatment of particular health conditions, mainly gastrointestinal disorders. The idea that the intake of particular bacteria can benefit food digestion as well as immune function emerged in the early 20th century, with the work of Russian-born zoologist and microbiologist Élie Metchnikoff. Interest in probiotics surged in the early 21st century, when more became known about the human microbiome. 
The essentials of probiotics
Probiotics are foods or supplements which contain live microbes intended to preserve or improve the “great” germs (typical microflora) in the body. Prebiotics are foods (generally high-fiber foods) that act as food for human microflora. Prebiotics are used with the objective of enhancing the balance of these microbes.
Probiotics remain in foods such as yogurt and sauerkraut. Prebiotics are in foods such as entire grains, bananas, greens, onions, garlic, soybeans and artichokes. In addition, probiotics and prebiotics are contributed to some foods and offered as dietary supplements.
Research is ongoing into the relationship of the gut microflora to disease. The health advantages of presently readily available probiotics and prebiotics have actually not been conclusively proved.
Nevertheless, side effects are unusual, and most healthy grownups can safely include foods that contain prebiotics and probiotics to their diet plans. Future research may lead to innovative probiotics with higher potential to enhance health.

The term probiotic is derived from Greek and literally means “for life.” It was first created in 1965 by Lilley and Stillwell to describe substances secreted by one microorganism that promote the development of another In 1974, Parker modified this definition to “… organisms and compounds which contribute to digestive microbial balance”. The existing definition of probiotics by Food and Farming Organization of the United Nations (FAO) and the World Health Organization (WHO) is “live microorganisms which when administered in appropriate amounts give a health advantage to the host”. Probiotic organisms require specific qualities to enable them to apply optimum restorative effects. Of these characteristics, there are some that are considered almost essential for a probiotic to have healing results, including gastric acid and bile salt stability, ability to stick to the intestinal tract mucosa, and capability to colonize the digestive tract 
The word ‘probiotic’ is originated from the Greek meaning ‘for life’ and has actually had numerous different meanings throughout the years. It was first utilized by Lilley and Stillwell in 1965 to explain substances produced by one microorganism which stimulated the growth of another. It therefore indicated the specific opposite of ‘antibiotic’ and its etymological pedigree was beyond reproach. However, its usage in this type did not continue and it was subsequently used by Sperti (1971) to describe tissue extracts which promoted microbial growth. It was not until 1974 that Parker utilized it in the context in which we will utilize it in this book. His definition was ‘Organisms and substances which contribute to intestinal tract microbial balance’. This meaning related probiotic usage to the intestinal tract microflora but the addition of ‘substances’ provided it a large connotation which would include prescription antibiotics. In an effort to improve the definition, Fuller (1989) redefined probiotics as ‘A live microbial feed supplement which beneficially affects the host animal by enhancing its intestinal microbial balance’. This modified meaning stressed the requirement for a probiotic to be practical.
