Your immune system works around the clock.

It helps your body respond to bacteria, viruses, and other threats, while constantly repairing and maintaining tissues. And although no single  food can magically “boost” your immunity, your everyday diet can provide many of the  vitamins, minerals, protein, and other nutrients your immune system needs to function properly.

The good news?

You don’t need exotic ingredients or expensive supplements.

Many helpful  foods are already sitting in your kitchen.

Here are 20 nutritious foods worth including in a balanced diet.

1. Citrus Fruits

Oranges, lemons, grapefruit, and other citrus fruits are well known for their vitamin C content.

Vitamin C supports normal immune function and also acts as an antioxidant.

Try adding orange slices to breakfast or using fresh lemon in water, salads, or cooked dishes.

2. Kiwi

Kiwi provides vitamin C along with fiber and other beneficial nutrients.

It’s an easy addition to breakfast, yogurt, or a fruit salad.

3. Red Bell Peppers

Red bell peppers are another excellent source of vitamin C.

They can be eaten raw, roasted, grilled, or added to soups and stir-fries.

4. Broccoli

Broccoli provides vitamin C, vitamin K, folate, fiber, and other plant compounds.
