Modern Diet Ruins Teeth

Modern Diet Ruins Teeth

A recent study shows that prehistoric man had better oral health than us—that was despite the fact that we now have toothbrushes, floss and modern dental technology at our disposal.

Researchers explain that our current poor oral health status has been affected by the way our diets have evolved since the Stone Age. Our counterparts thousands of years ago hunted and gathered their food. When farming started, the typical diet changed significantly, and during the industrial revolution our diets shifted again so that it is now dominated by processed and manufactured foods.

Researchers from the University of Adelaide, The University of Aberdeen and the Wellcome Trust Sanger Institute in Cambridge have been analyzing the DNA found in calcified bacteria on the teeth of humans from ancient and modern times. They have discovered that the composition of bacteria in the mouth has changed completely over thousands of years.

One of the study’s authors has explained:

“The composition of oral bacteria changed markedly with the introduction of farming, and again around 150 years ago. With the introduction of processed sugar and flour in the Industrial Revolution, we can see a dramatically decreased diversity in our oral bacteria, allowing domination by caries-causing strains. The modern mouth basically exists in a permanent disease state.”

That last sentence is of great concern!
