Doctor Weston A. Price, DDS, studied 14 isolated tribes over a period of years in order to learn about how people are affected by diet and nutrition. He determined that traditional diets produce better physical health and emotional stability than do diets based on convenience foods. From his research, Dr. Price concluded that:
- Dental decay is caused primarily by nutritional deficiencies.
- Although radically different, 14 tribal diets provided almost complete immunity to tooth decay and resistance to disease.
- The diets contained no refined or devitalized foods.
- Laboratory analyses revealed that all of these diets were unusually high in protein, vitamins, minerals and especially in fat soluble factors found in animal fats.
- Contact with civilization, followed by adoption of the "displacing foods of modern commerce," was disastrous for all groups studied.
- Rampant dental caries were followed by progressive facial deformities in children born to parents consuming refined and devitalized foods.
- These changes consisted of narrowed facial structure and dental arches, along with crowded teeth, birth defects and increased susceptibility to infectious and chronic disease.
- Significantly, when some natives returned to their traditional diets, open cavities ceased progressing and children subsequently conceived and born, once again had perfect dental arches and no tooth decay.
- If civilized man is to survive, he must incorporate the fundamentals of primitive nutritional wisdom into his modern life-style.
