2. Rotten Teeth
Sugar in any form rots the teeth, and it’s really the only thing that does.
Consider the difference between the populations of Nigeria, where very little sugar is eaten, and America, where people eat way too much. In Nigeria, only 2% of the population has tooth decay; in America, a staggering 92% of people do.
The acids in our diet can also contribute to enamel loss, but its sugar that creates cavities.
