Utilizing secondary data from academic journals, industry reports, and health organizations, the study synthesizes findings that highlight the critical role of nutrient-dense foods in enhancing healthcare workers' performance. Key elements such as omega-3 fatty acids, B-vitamins, antioxidants, and hydration are examined for their effects on mental clarity, energy levels, stress reduction, and immune support. The findings suggest that implementing functional nutrition strategies within hospitals can lead to improved employee health, increased job satisfaction, and reduced absenteeism, ultimately contributing to higher-quality patient care. This research underscores the need for healthcare institutions to prioritize nutrition as a fundamental aspect of employee well-being and organizational efficiency.
