Top 10 Superfoods to Boost Your Immune System

Our immune system is our body's frontline defense against disease and infection. As the seasons shift — bringing about cooler weather, pollen spikes, and close-contact indoor activities — maintaining a strong immune system becomes even more critical. While no single food can guarantee immunity, scientific research shows that certain foods can prime and support your body's natural defenses.

Today, let’s explore 10 science-backed superfoods that can help you stay vibrant and resilient throughout the year.

Why Nutrition Matters for Immunity

The immune system relies on a steady supply of nutrients to function optimally. Vitamins, minerals, antioxidants, and anti-inflammatory compounds found in whole foods help to:

• Increase production of immune cells

• Enhance communication between cells

• Reduce oxidative stress and inflammation

• Support the integrity of the skin and mucous membranes (your body’s first physical barrier against pathogens)

According to a 2020 review published in Frontiers in Immunology, a nutrient-dense diet can significantly strengthen both innate and adaptive immunity.
