All that the provided reference states is:
Whatever the real origin, yogurt is mentioned in records of ancient civilizations from India to Iran; by 500 BCE, holy men on the subcontinent had labelled the delicious mixture of yogurt and honey "the food of the gods".
Is this true? Who are these holy men and where do they label the mixture of yoghurt and honey, "food of the gods"? Where does the date of 500 BCE come from?
