Probiotics: new trend or old medicine?
AbstractProbiotics may be described as live organisms that are microscopic in size, which when administered in adequate amounts, improve an individual’s health. Probiotics, such as lactobacilli that is ingested in yoghurt, have been used since the early 20th century to treat a variety of ailments, typically infections of the mucosal surfaces of the body, such as the gastrointestinal tract or the vagina. In fact, probiotics have been used for as long as people have been eating fermented foods. Most probiotics are bacteria, but some yeasts are also used as probiotics, e.g. Saccharomyces boulardii (also called S. cerevisiae or Brewer’s yeast).
