Research studies show that the consumption of refined carbohydrates — like sweetened beverages and sweet and starchy foods — promotes the growth of acid - producing bacteria in the mouth and the progression of tooth decay.3 One exception is xylitol,
a naturally sweet compound found in birch trees, berries, mushrooms, corn husks, and oats.
It was back in 1908 when Japanese chemist Kikunae Ikeda proposed umami as a fifth taste — in addition to salty,
sweet, sour, and bitter — brought about by glutamic acid, a
compound which
naturally occurs in a number foods.
