If you’re reading this, you already know how important eating well is for good health. As Dr. Mark Hyman puts it, “Food is literally the most powerful medicine you have available to control your health.” That’s always true—but right now, as we’re all trying to protect ourselves and our families from a global pandemic, eating healthy feels even more urgent.
Luckily, there are many commonly available, delicious foods that you can incorporate today—no matter what your particular taste, eating style, cooking ability or budget—that are specifically powerful for boosting your immune system.
Here are some nutrients to focus on, and the foods where you’ll find them in abundance. Of course, keep getting as wide a variety of foods onto your plate as possible; eat plenty of vegetables, beneficial fats and high-quality protein for overall good health.
Vitamin C from
Why it’s helpful: Vitamin C is an antioxidant, so it fights free radicals in the body, helping to reduce inflammation. Research suggests vitamin C may help prevent respiratory infections, and aid in treating them when they do occur. A lack of vitamin C is associated with increased risk of illness.
Where you’ll find it: Red bell peppers, citrus, strawberries, spinach, kale, broccoli, cauliflower
- Protein Power Smoothie: Along with strawberries, this fast and easy smoothie gets an extra shot of vitamin C from a secret ingredient: Red bell pepper.

- “Flu Shot”: This juice is an immune-boosting powerhouse, with three different kinds of citrus (grapefruit, blood orange and lemon). Raw honey, cinnamon, garlic and ginger all pitch in illness-battling properties, and make this elixir bracingly delicious.
Why it’s helpful: Research suggests that vitamin D may help regulate the immune system, so the body doesn’t under- or overreact (the latter can lead to autoimmunity). Lack of vitamin D is also associated with greater risk of infection.
Where you’ll find it: Salmon, sardines, egg yolks, fortified dairy
- Curry Frittata with Onions, Broccoli & Cherry Tomatoes: Eggs are a great source of vitamin D—and this tasty frittata, great for any meal of the day, gets bonus points for also incorporating vitamin C-rich broccoli.

Canned wild salmon, featured in this recipe, is a budget-friendly and convenient way to enjoy it. These tasty patties get extra points for being rich in protein (also important for immunity), and for having anti-inflammatory turmeric.

Why it’s helpful: Vitamin A also helps regulate the immune system, so that it operates efficiently. Plus, research suggests vitamin A may help protect children from pneumonia and other respiratory illnesses.
Where you’ll find it: Animal sources such as dairy, fish, and meat, have preformed vitamin A. With plant sources, you eat compounds called carotenoids, which the body converts into vitamin A. Carotenoid-rich foods include carrots, sweet potatoes, cantaloupe, spinach, pumpkin, and winter squash

Vitamin A is fat soluble, so you need to eat fat with it in order for your body to absorb it.

Serve it alongside fish, chicken or steak for dinner—or have it with a fried egg on top (vitamin D!) as something different for breakfast.
Why they’re helpful: Fermented foods contain probiotics, beneficial bacteria that help crowd out bad bacteria in our microbiomes that can cause inflammation and other illnesses. Regularly including fermented foods in your diet helps maintain a healthy gut, the place where much of the immune system lives.
Where you’ll find it: Yogurt, kefir, sauerkraut and pickles (make sure the label says “raw” or “fermented”), kimchi, miso, apple cider vinegar (must contain the “mother”), kombucha
