After millions of years of satisfying our sweet tooth with an occasional lick of honey, today we’re dumping between 29 and 40 teaspoons of refined sugar onto our daily plates, which is radically different from even our grandparents’ intakes that were closer to 4 teaspoons at the turn of the 20th century. Sugar is not just in candy, cakes, and desserts, it’s also in baked beans, catsup, fruited yogurts, granola bars, and cereals, to name only a few. It’s no wonder that only 2% of Paleolithic teeth were decayed, compared to 60% of teeth in the 19th century, and 95% of teeth today. (Excerpt from my book, The Origin Diet.)
