What can you do to keep your kids cavity-free? Feed them fewer carbs.
Dr. Roger W. Lucas, pediatric dentist, explains the link between carbs and cavities in his book More Chocolate, No Cavities: How Diet Can Keep Your Kid Cavity-Free. Simple carbohydrates such as flour and juice feed mouth bacteria that cause cavities. On the other hand, high fat and protein foods don’t.
The dentist even claims that it is better to give children really dark chocolate (70%+) than snacks such as juice and crackers in preventing cavities. The chocolate contains a lot of fat, that protects the teeth from the sugar.
