Chewing gum lowers stress and improves memory. What it does not do is improve oral health and freshen the breath.....you have to clean your tongue of the food deposits to get a fresh breath! The global chewing gum market is worth over $20 billion, and because chewing gums are mistakenly associated with oral health, some clever companies have begun selling "probiotic chewing gum" which contains artificially added probiotics. Swedish probiotics producer BioGaia, offers BioGaia Probiotic Chewing Gum, a sugar-free gum containing the healthy bacteria Lactobacillus reuteri, which fights against the bad bacteria that cause cavities.
A Canadian company, Cultured Care is also selling Probiotic Gum, which contains artificially added Streptococcus salivarius. Research by microbiologists at the University of British Columbia shows that this probiotic produces antibacterial substances that can kill certain bad bacteria, and hence protects against oral thrush, dental cavities, and bad breath. Yogurt is the one food that contains natural probiotics but Dr. Bob Hancock, professor in the department of microbiology and immunology at the University of British Columbia says: "I don't really like yogurt and there aren't necessarily enough of the right probiotics in yogurt to make a difference anyway. The thing about the gum is that it seems like a good way to introduce the healthy organisms to the oral cavity."
