The answer is: Pulses and water

Daniel 1:12

In the heart of Babylon, young Daniel and his companions stood firm in their convictions even when faced with royal edicts. Instead of feasting on the royal menu, rich in meat and wine, they opted for "pulses and water." Pulses, which include legumes like lentils and beans, were common in the ancient Near Eastern diets and perhaps symbolize simplicity and humility compared to the lavishness of royal fare.

So why pulses? They provide essential nutrients, are high in protein, and their consumption reflects a commitment to dietary purity and personal beliefs. It’s fascinating how this moment foreshadows a broader theme in the Book of Daniel—faithfulness in adversity. His piety resonates throughout scripture and illustrates a profound principle: integrity and reliance on divine wisdom over worldly allure.

The intriguing part is how this "vegetarian" choice permeated throughout biblical culture. Fruits, vegetables, and grains are often celebrated in various scriptures, showcasing the diverse celebrations of God’s creation. On the other hand, there are also biblical echoes pointing to animal sacrifices and meals typically associated with covenantal community gatherings.

Even in Daniel's time, the differentiation of diet wasn’t solely a matter of physical sustenance but a bold declaration of identity and devotion. It highlights that sometimes, standing up for one's principles may require tasting life differently, and suggests that many who walk a faithful path face unique choices in their journey—a beautiful testament to the resilience seen throughout sacred texts.
