Cold and flu season is here, and many little ones are already coming home with scratchy throats and sniffles. While a daily multivitamin can help fill gaps, I prefer to support immunity with wholesome, nutrient-dense foods. Whenever possible, I like to fight colds with food.
Vitamin C is one of the most commonly mentioned nutrients for supporting the immune system. Although studies differ on how much it prevents or shortens illnesses, I find it worthwhile to increase Vitamin C–rich foods during this time of year.
Here are my top five foods that deliver a Vitamin C boost:

Bell Peppers: Bell peppers are versatile and easy to eat raw or cooked. Yellow peppers are especially high in Vitamin C, providing about 184 mg per 100 g serving.
Broccoli: Broccoli is great raw or steamed and easy to include in generous portions. One cup of chopped broccoli delivers roughly 81 mg of Vitamin C.
Strawberries: These sweet berries can offer as much Vitamin C as oranges, though they may be less abundant in colder months. Expect about 59 mg of Vitamin C per 100 g serving.
Green Chili Peppers: Small but mighty, green chilies contain a surprisingly large amount of Vitamin C. A single green chili can provide about 109 mg—add a couple to a stir-fry for an easy boost.
Kiwi: Kiwi is a favorite for many because it’s tasty and portable. Each fruit contains around 84 mg of Vitamin C, and it’s easy to eat several in one sitting.
One of my go-to recipes featuring broccoli is Oriental Tofu Salad. I often boost its immune-supporting potential by adding chopped green chilies and diced bell peppers, and serve it alongside kiwi, oranges, and strawberries for a Vitamin C–packed meal.
Those are my preferred foods to increase Vitamin C—what are your favorite ways to keep colds at bay?
