One of the best known dietary laws is the prohibition to mix meat and milk. The Sefer HaHinuch points out that one is not allowed to eat, cook, or benefit from, a mixture of meat and milk and this broad scope suggests that the concern is not just physical or even spiritual health. Perhaps the answer is found in the opening chapter of the Book of Daniel. The young Daniel, captive in the Babylonian palace, would not defile himself with the king’s provisions and with his drinking wine instead he insisted let them give us from the grains that we may eat, and water that we may drink. Daniel understood that without commitment to kashrut, his Jewish identity may not outlive the Babylonian captivity.
