Navigating the New Normal: 15 Essential Health Protocols for Post-Pandemic Travel

6. The Impact of Nutrition on Immune Health

Nutrition plays a foundational role in building and maintaining immune strength. During the pandemic, increased attention was given to diets rich in vitamins, antioxidants, and anti-inflammatory properties. Nutrients such as vitamin C, D, zinc, and protein became part of public health discourse. While no food alone can prevent illness, a balanced diet supports the body’s ability to respond to infections. The pandemic also exposed global food inequities and the importance of access to nutritious options. As we emerge from crisis mode, nutrition must remain a priority—not only for recovery but for strengthening long-term immune defense and public health equity.
