The Effect of a Chewing-Intensive High-Fructose Diet on Oral Halitosis

The effect of a chewing-intensive high-fiber diet on oral halitosis was examined. Fast food is engineered to be eaten fast, so the thickness of the tongue coating might increase and that could contribute to bad breath. The participants were randomized to a high-Fiber, high-chew meal with a whole grain roll with jam and a raw apple versus a low-fiber low-chew white bread roll with jelly and it cooked out. And the result? A significantly lower bad breath score immediately after the high- fiber meal and then two and a half hours later compared to the low-f fiber meal.
