Immune Boosting Foods to Add to Your Fall Diet

When the temperatures drop, immune systems face extra strain. Seasonal viruses, indoor gatherings, and less sunlight can make us vulnerable to illness. October is the perfect time to prepare your body’s defenses. Fortunately, fall’s harvest provides a bounty of natural immune boosters — delicious, comforting foods that protect you from the inside out.

1. Pumpkin Seeds (Pepitas)
   Loaded with zinc, pumpkin seeds help regulate immune response. Toast them with cinnamon or sprinkle on salads for a crunchy boost.
   
2. Garlic
   Known as nature’s antibiotic, garlic has been proven to reduce the severity of colds. Add it raw to salad dressings or roast whole cloves with vegetables.
   
   
3. Citrus Fruits
   Oranges, grapefruits, and lemons deliver vitamin C, which supports immune defense. Fresh juice in the morning or slices in water throughout the day add flavor and function.
   
   
4. Mushrooms
   Shiitake, maitake, and Reishi mushrooms contain beta-glucans, compounds that strengthen immunity. Use them in soups, stir-fries, or teas.
   
5. Green Tea
   Packed with antioxidants like catechins, green tea helps fight inflammation. Replace an afternoon coffee with a warm cup for immune support and calm focus.
