The answer is: Pulses and water

Daniel 1:12

In the Book of Daniel, we stumble upon a fascinating moment of stood-up loyalty and wisdom. When brought to the Babylonian court, Daniel and his friends, Shadrach, Meshach, and Abednego, were faced with being inculcated in the royal lifestyle, necessitating a departure from their dietary customs. They chose pulses (a kind of legume) and water instead of indulging in the rich foods from the king's table. This choice tangoed not only with dietary restrictions but also demonstrated their faith and commitment to their values in a foreign land.

Pulses, often honored for their nutritional benefits, contain protein, fiber, and essential vitamins. Some scholars suggest that this vegetable-forward diet may have influenced Daniel’s exceptional ability to maintain his health and vigor, prompting eventual wins in wisdom and favor with the king. The whole saga speaks to a broader theme in literature—a refusal to conform means staying true to oneself.

An interesting tidbit is that the ten-day test they proposed resulted in remarkable outcomes. The healthier physiques of Daniel and his friends were seen as divine providence showcasing the belief that one's faith can lead to strength and resilience. This episode in Daniel's life also parallels various biblical narratives, shedding light on the recurring motif of faith, perseverance, and God's providential hand in times of challenge—an echo of stories from many in the Israelite tradition. Food for thought, indeed!
