Boosting Immunity with Seasonal Superfoods

The holiday season is a time for gathering with friends, family, and community—but it can also be a time when our immune systems need extra support. With colder temperatures, busy schedules, and more time spent indoors, focusing on nutrition becomes key to staying healthy, active, and energized.

The good news? Winter brings a variety of seasonal superfoods packed with nutrients that can help keep your body strong and your immune system ready to take on whatever the season brings. Here are a few of my favorites and simple ways to enjoy them:

Top 5 Winter Superfoods

1. Winter Squash
Varieties like butternut, acorn, and spaghetti squash are winter staples for good reason. They’re rich in vitamins A and C, antioxidants that support immune health, vision, and skin.

Try it: Roast butternut squash with a little olive oil and cinnamon for a warm, nutritious side dish, or add it to soups and stews for extra comfort and flavor.

2. Citrus Fruits
Oranges, clementines, and grapefruits are at their juicy best this time of year. Loaded with vitamin C, they’re your go-to for boosting immunity and fighting off colds. Plus, their natural sweetness makes them a satisfying snack.

Try it: Toss grapefruit segments with a handful of baby spinach, walnuts, and a light vinaigrette for a refreshing salad.

3. Dark Leafy Greens
Kale, spinach, and Swiss chard thrive in cooler weather and are packed with vitamins K, A, and C as well as iron and fiber. These greens not only strengthen your immune system but also keep digestion on track.

Try it: Add a handful of greens to smoothies, omelets, soups, or sautés.

4. Nuts and Seeds
Almonds, walnuts, and pumpkin seeds provide zinc, protein, and healthy fats, all essential for immune function and sustained energy.

Try it: Sprinkle chopped nuts on oatmeal, yogurt, or salads for a nutrient boost, or enjoy them on their own for a portable, satisfying snack.

5. Root Vegetables
Carrots, sweet potatoes, and beets are not only hearty and versatile but also packed with beta-carotene (which converts to vitamin A), fiber, and antioxidants.

Try it: Roast a mix of root veggies with herbs and olive oil for a colorful, nutrient-dense side dish.
