7 Seasonal Foods to Boost Your Immune System This Thanksgiving
October 31, 2025
As cold and flu season arrives, your immune system could use a little extra support. The good news: fall produce is packed with nutrients that help you stay healthy and energized. Add these seven seasonal foods to your Thanksgiving table and enjoy the benefits all season long.
1. Sweet Potatoes
Rich in beta-carotene, sweet potatoes support immune health by helping your body produce vitamin A. Try roasting them or swapping them into your favorite mashed potato recipe for a colorful twist.
2. Cranberries
These tart berries are bursting with vitamin C and antioxidants that help your body fight off illness. Fresh cranberry sauce or a sprinkle of dried cranberries on a salad adds both flavor and a health boost.
3. Brussels Sprouts
High in vitamin C and fiber, brussels sprouts help keep your immune system strong and digestion on track. Roast them with olive oil and a drizzle of maple syrup for a simple, nutritious side.
4. Garlic
A natural immune booster, garlic contains compounds that have antiviral and antibacterial properties. Use it generously in stuffing, mashed potatoes or roasted vegetables for extra flavor and protection.
5. Citrus Fruits
Oranges, grapefruits and clementines shine in late fall. Their vitamin C helps reduce the length of colds and supports your body’s natural defenses. Keep a bowl on the counter for an easy, immune-system-friendly snack.
6. Pumpkin
Pumpkin isn’t just for pie; it’s full of vitamin A and antioxidants that help your body fight infection. Add pumpkin purée to soups, smoothies or oatmeal for a dose of seasonal nutrition.
7. Spinach
Loaded with iron, vitamin E, and antioxidants, spinach helps strengthen your immune response. Serve it in salads, stir it into casseroles or sauté it as a simple side.
This Thanksgiving, fill your plate with color. These seasonal foods don’t just taste great; they can lead to lasting change. AtlantiCare’s dedicated teams are here to help you live healthier every day of the year.
