Peat Archive

Ray Peat discussed dental health in the context of nutrition and hormonal balance. He argued that tooth decay is primarily a nutritional disease related to calcium and phosphorus metabolism, vitamin D status, and thyroid function — not simply about sugar consumption and oral bacteria. He was critical of water fluoridation, noting evidence that fluoride is an enzyme inhibitor that can suppress thyroid function.

Peat recommended adequate dairy consumption (for calcium and phosphorus in proper ratio), vitamin D, and vitamin K2 (which directs calcium to bones and teeth rather than soft tissues). He noted that Dr. Weston Price's research documented how traditional diets produced excellent dental health without modern dental care.
