A term used in conjunction with probiotics is "prebiotics" which describes the process or describes foods that have added non-living microorganisms to substances in order to improve human health issues through food products. At the present time, probiotic usage is mainly focused on solving a universe of health issues associated with organs related to the colon such as the mouth, throat, stomach, small intestine, and the vaginal canal. Prebiotic usage however, is focused mainly on health issues affecting the colon. Some of the foods and nutritional products that are being supplemented with prebiotic or probiotic microbes include vitamins and medications, yogurt, snack bars, snack mixes and some snack spreads, desserts, milk products for adults and infants, cheeses, and meat products.
