Our bodies are naturally wired to conserve energy, a trait inherited from ancestors who faced food scarcity. Even today, we expend about 1,400 calories daily just to stay alive, leading us to instinctively avoid unnecessary physical activity despite readily available energy sources. This perspective, distinguishing between athletic performance and true health, is explored by Daniel Lieberman, a Harvard professor of Human Evolutionary Biology.

Maya Salsedo, a 2012 Brower Youth Award winner, champions food justice, driven by her family's history of food insecurity. Descendants of Puerto Rican emigrants who worked in Hawaiian sugar cane fields, her family consistently faced challenges accessing healthy food.

This experience spurred Salsedo to action. In 2011, as a youth organizer with Rooted in Community, she proposed the Youth Food Bill of Rights.

Her work has since inspired peers nationwide, establishing a foundation for dialogues on what food justice means to today's youth.
