In the 1900s, Dr Weston A. Price, a dentist, did extensive research on the link between oral health and physical diseases. He was one of the major nutritional pioneers of all time, and his classic book Nutrition and Physical Degeneration is full of wonderful pictures documenting the perfect teeth of the native tribes he visited who were still eating their traditional diets.
Your Diet May be Even More Important Than Your Toothbrush
For healthy teeth and gums, nothing may be more important than your diet. Dr Price found in his work that the native people's teeth were perfectly straight and white, with high dental arches and well-formed facial features. And there was something more astonishing: none of the people Price examined practiced any sort of dental hygiene -- not one of his subjects had ever used a toothbrush!
Dr Price noticed some similarities between the native diets that allowed the people to thrive and maintain such healthy smiles. Among them:
The foods were natural, unprocessed, and organic (and contained no sugar except for the occasional bit of honey or maple syrup).
The people ate foods that grew in their native environment. In other words, they ate locally grown, seasonal foods.
Many of the cultures ate unpasteurized dairy products, and all of them ate fermented foods.
The people ate a significant portion of their food raw.
All of the cultures ate animal products, including animal fat and, often, full-fat butter and fatty meats.
If you, too, eat properly and maintain optimal health, you're highly unlikely to develop cavities or other dental problems. They really only occur when you're eating the wrong foods. So pay attention to your diet, as this is a key to keeping you safely out of the dentist's chair!
