Seasonal transitions often bring sudden changes in temperature, humidity, and airborne allergens, making the body more vulnerable to infections like the common cold, flu, sore throat, and cough. A strong immune system is your best defense, and adding nutrient-rich superfoods to your daily diet can help your body fight off seasonal illnesses naturally.

1. Citrus Fruits

Oranges, lemons, sweet limes, grapefruits, and tangerines are packed with vitamin C, a powerful antioxidant that supports immune function and helps the body produce white blood cells. Regular consumption may reduce the duration and severity of common colds.

Benefits:

• Strengthens immunity

• Supports faster recovery from infections
