The Pros of Probiotics

There has been lots of buzz in the media touting the benefits of probiotics as an essential component of a healthy diet.  Are you confused by this term, which sounds more like a chemistry experiment than something that should be a part of your diet?  Here’s some basic information on the pros of probiotics!

Probiotics are “good” or “friendly” bacteria that is found either naturally in our food, or is added to food during the processing.  They can also be found in dietary supplements.  Examples of food that may contain probiotics are yogurt, kefir (a fermented milk beverage), miso, tempeh, and some juices and soy beverages.  So, when you see a product that claims to have “live active cultures,” that is referring to probiotics.

Most probiotics found in food act similarly to those “good” bacteria naturally found in our digestive system.  Our normal digestive system contains about 400 types of these “good” bacteria that help to keep it working properly.  They are important for proper development of the immune system, to protect against microorganisms that could cause disease, and to aid in the digestion and absorption of food and nutrients.  The science behind the potential benefits of probiotics is still in an early stage; however there is some encouraging evidence for the use of probiotics in the following areas:

• To treat diarrhea (this is the strongest area of evidence) and/or promote regularity.To prevent and treat infections of the urinary tract and intestines.To treat irritable bowel syndrome To reduce recurrence of bladder cancer 
• To prevent and manage eczema in children

Scientists are not exactly sure how probiotics work but they believe that the good bacteria replace or crowd out the bad bacteria in the intestinal tract. Another theory is that the good bacteria keep the intestinal tract acidic so bad (harmful) bacteria can't survive.  

It’s important to realize that probiotics work like a charm in some people and don't do a thing in others. Probiotics are not a magic bullet to prevent or cure disease, but they are considered safe since good bacteria are already a part of the digestive system. They can act to assist in improving digestive health, but should not replace a healthy and well balanced diet.
