• Beta-glucans: These are naturally occurring polysaccharides found in oats, barley, and mushrooms that enhance the immune response by activating immune cells.
• Zinc: Present in nuts, seeds, and legumes, zinc is crucial for immune cell development and function.
• Antioxidants: Foods rich in antioxidants, such as berries and green tea, help combat oxidative stress, which can weaken immune function.
• Polyphenols: Found in foods like dark chocolate, berries, and green tea, polyphenols have anti-inflammatory properties that support immune health.
