Probiotics is one of the newest, hottest nutrition topics. What exactly are probiotics? And do you need them?
Probiotics are beneficial bacterial that are similar to those found naturally in your gut. Studies of probiotics are rather new, but studies suggest there are benefits of using probiotics in improving symptoms of gastrointestional diseases. The mechanism of these good bacteria to improve symptoms are not completely understood.
The problem with advertised products containing probiotics is that NOT all probiotics are the same. There are a variety of species and each specie does not necessarily act in a comparable manner.
Yogurts are often recommended as a source of probiotics; HOWEVER, not all the live cultures can survive the acidic environment of your stomach. Many yogurts (in the US) are pasteurized; pasteurization kills bacteria!
Many of the studies contain considerable limitations and therefore (in the medical field) no recommendations have been suggested; however, studies, even with their limitations are promising and hopefully in the future recommendations will transpire. (Promising studies exist with the following diagnoses: ulcerative colitis, antibiotic associated diarrhea, infectious diarrhea, irritable bowel syndrome, lactose intolerance, hepatic encephalopathy, and allergies!)
In the mean time, if you feel your symptoms are improving with the addition of probiotics, there is no reason to discontinue taking them; there does not appear to be any negative consequences associated with taking probiotics. (For more information please read here and here!)
