The link i provided gives info on Weston Price who traveled the world researching physical degeneration and diet. He found the tribes and cultures that relied on food in the area they lived rarely if ever suffered from health problems. The people who learned to transmute there foods into digestable material had strong healthy teeth, bones, facial structure, ect. However the cultures that had lets say a railroad going into there town, making them subject to imports of sugar, flour, and other denatured foods, ended up having epidemics of diseases, poor health, skeletal deformations, rotting teeth, ect.
The health of our mouth is in close relation to the health of the organs in our body. We shouldnt need braces or regular health checkups if our parents ate properly and if we then continue to eat properly once born. Obviously it is unfortunate if we didnt have such luck however it is wise to correct our eating habits in order to encourage a strong future for ourselves and our children.
