Eating sugar and genetics may not be the culprits in tooth decay. A dentist, Dr. Weston A. Price, wrote in Nutrition and Physical Degeneration about cultures in the world with no dental access or toothpaste use who have perfect teeth. Other cultures with similar diets experience excessive tooth decay. Price theorized that the difference was from dietary factors.
Two other doctors hold the same theory. Sir (Dr.) Edward Mellanby, discoverer of Vitamin D deficiency causing rickets, and his spouse, Dr. May Mellanby, found that poorly formed teeth, which develop as children grow, are more susceptible to decay and concluded that diet affects oral health by three things: getting sufficient minerals, fat soluble vitamins like A, D, E, and K, and how bio-available these are and how well the body is absorbing them. The key is these are influenced by sugar consumption plus phytic acid in the diet.
Phytic acid is phosphorus bound with other molecules creating a phosphorus that is difficult for humans and animals with one stomach to absorb. The phytic acid molecules not only block phosphorus availability, but bind readily with other minerals like calcium, magnesium, iron and zinc, making them unavailable to the body too.
Phytic acid is a principal form of phosphorus storage in plant tissue, in the bran part of grains and other seeds. It is also found in nuts and legumes with smaller amounts in some fruits and vegetables. The foods especially high in phytic acid include seeds, nuts, bran, oatmeal, and soybeans. View a list of the phytic acid content of various foods to see which to avoid and methods to decrease phytic acid content in them.
The human body converts phytic acid into phytates which are unabsorbable and remove calcium from the body. Consumption of large amounts of phytic acid results in lost calcium and lower absorption rates of other minerals.
Agricultural use of high phosphorus fertilizer is increasing the phytic acid content in many foods which are abundant in the modern diet. The result is that most Americans have higher rates of tooth decay, mineral deficiencies and osteoporosis. The body in mineral-starvation mode uses as few as possible which the adult body may handle for several years, but children lacking calcium and phosphorus suffer poor bone growth and rickets, are shorter, and have narrow jaws and tooth decay. Those lacking zinc and iron are anemic and may have mental retardation.
A poorly formed jawbone results in teeth not spaced correctly requiring braces. Teeth and bones can regenerate dentin, the tooth layer under the enamel, and remineralize from the outside of the tooth when phytic acid is removed from the diet and minerals and fat soluble vitamins are added. Phytic acid must be minimized in the diet, reversing it to high in animal fats and fat soluble vitamins and low in grains, sugars, and vegetable oils. In addition to healthy bones and teeth there are side benefits of optimal weight, improved concentration, and increased energy.
The Drs. Mellanby published their study in the British Medical Journal. Read the book Cure Tooth Decay: Heal and Prevent Cavities with Nutrition by Rami Nagel for a better understanding of phytic acid and details on how to reverse affects on teeth and bones.
