Not everything that glitters, is edible: US FDA

Not all food decorative glitters are safe to eat, warns the US Food and Drug Administration (FDA). By law, edible glitters and dust products must list their ingredients. Edible ingredients include cornstarch, sugar and colour additives. According to the FDA, only glitters that mention 'edible' on the label are safe to use. If the product just mentions 'non-toxic', it should be avoided.
