Certain diets may give bad breath a big boost

Consuming pungent foods like garlic, onions, smoked fish or asparagus can give people a powerful case of halitosis, but ultimately the residue from these foods can be scrubbed away or rinsed out with a specialty breath freshener. Diets can get truly halitosis-inducing, though, is when they advocate skipping entire food groups.

Recently, the British Dietetic Association named the Dukan Diet one of the five worst weight-loss regimens of the year. The reason, according to organization spokesperson Sian Porter, was that "The 'Do-can't diet' is hard to stick with, hard on your kidneys and expensive."

Similar to the Atkin's Diet, the Dukan Diet is an eating system that invites practitioners to consume almost nothing but protein. The regimen itself is ketogenic, meaning it relies on putting the body into a state of ketosis, in which the organs burn fat rather than carbohydrates. This process can increase weight loss, but many health experts say the Duakn system is inadvisable.

Dian Griesel, the co-author of TurboCharged, a book about fruit-based dieting, said that ketosis can cause halitosis and other negative side effects.

"Participants complain of constipation, fatigue and bad breath. This indicates dietary imbalance," Griesel stated.

A diet is one's personal choice, which is why no matter what an individual eats, they can be sure to reduce bad breath by using an oral care probiotics product.
