A healthy immune system assists in safeguarding the body against diseases and infections. Although there is no single food that can provide immunity, some nutrients are important in building your body’s natural defenses. Adding immune-boosting foods to your daily meals can promote overall health and resistance to common diseases.

Vitamin C is one of the most potent immune-boosting nutrients. Vitamin C raises white blood cell levels, which drive infections away.

Since the body does not store vitamin C, eat these foods every day for a sustained immunity boost.
