In what way is knowledge bread?

Knowledge is often referred to as "bread" in the metaphorical sense that it sustains and nourishes the mind, much like bread nourishes the body. Just as bread is a fundamental staple in many diets, knowledge serves as a foundational element in personal growth and understanding of the world. It provides the essential nutrients for critical thinking, creativity, and informed decision-making, enabling individuals to thrive intellectually and socially. Additionally, like bread, knowledge can be shared and broken down into smaller pieces, allowing for communal growth and learning.
