According to a new study , sugar-free products cause serious dental issues. Say what?  Say goodbye to your tooth enamel, that's what. A recent study by the University of Melbourne's Oral Health Cooperative Research Centre goes with the argument against these drinks. The research states that these sugar-free drinks we enjoy can actually cause extensive damage to the tooth enamel. The research team conducted tests for 23 different types of drinks (soft drinks and sports drinks). Even if the drink is sugar-free, they found that the drinks have acidic additives and if there are low pH levels, they can induce damage to the dental enamel. The researchers found that there is an occurrence of dental enamel softening and tooth surface loss after the tooth's contact to...

Epigenetics has had an increasing role in biological and medical research, newsw...
