A probiotic is a product with a sufficient number of viable microorganisms to alter the host's microflora to produce beneficial health effects (Schrezenmeir & de Vrese, 2001). Probiotics are ingested in an attempt to prevent or treat a specific pathologic condition. Although the desired effect is similar, prebiotics are different. Prebiotics are nondigestible food ingredients, such as inulin and oligosaccharides, that stimulate development or activity of beneficial intestinal bacteria (Gibson & Roberfroid, 1995). Synbiotics are products that contain both pre- and probiotic agents and imply synergy between the two with enhanced benefits to the host (Conway, 2001
