Inside our digestive tracts, trillions of bacteria have taken up residence. These bacteria need us and we need them to survive. It's a symbiotic relationship we have with these parasites. Although we don't often think about it, the bacteria that live within us help digest our foods, protect us from disease, and improve immune functions. Without bacteria, we would not survive very long.

Unfortunately, many of us suffer from illnesses related to an imbalance of these gastrointestinal bacteria- illnesses caused by too many aggressive bacteria and too few defensive, "healthy" ones. Allergies, eczema,vaginal and urinary tract infections, diarrhea, and inflammatory bowel disease are just a handful of the medical conditions now known to arise when unhealthy bacteria ovegrow and outnumber the healthy ones in our gastrointestinal tracts. Fortunately, probiotics provide us with an easy way to put things back into balance again.

A probiotic is any product that contains enough live microorganisms to bring about beneficial health effects. Essentially, probiotics are healthy bacteria- healthy bacteria that are easily ingested and help to restore the balance inside our digestive system.

In this book, we will find out just why we need these bacteria and explore which probiotics, according to current scientific and medical research, are most effective for treating a variety of health concerns.
